What is Bituminous waterproofing?

Bituminous waterproofing systems are designed to protect residential and commercial buildings. Bitumen is a mixed substance made up of organic liquids that are highly sticky and viscous, and are waterproof.

Roofing felt components

Bituminous membranes are made up of more than one product:
Bitumen - Mixed with a filler component such as limestone or sand. Polymers are added to the bitumen such as APP (atactic polypropylene) a plastic additive that gives rigidity and tear resistance, or SBS (styrene butadiene styrene) a rubber additive that gives more elastic benefits.
Base Products - Polyester, fibre glass, rag fibre (hessian), and paper. These products are bought in roll format and are pulled through the bitumen mixes on huge rollers. The base product becomes saturated in huge tanks by the tar like bitumen substance, creating rolls of waterproof material.
Mineral - (Optional) Small granules are added to the top of the felt, decreasing the products fire vulnerability.
Thin, transparent film - This product is added to the base of the felt during manufacturing on all torch-on products. This stops the felt from sticking to itself when rolled up during the packaging process.

Composition

The complex chemical composition of bitumen makes it difficult to identify the specific component(s) responsible for adverse health effects observed in exposed workers. Known carcinogens have been found in bitumen fumes generated at work sites. Observations of acute irritation in workers from airborne and dermal exposures to fumes and aerosols and the potential for chronic health effects, including cancer, warrant continued diligence in the control of exposures.

Benefits

Bituminous roofing products are used for waterproofing roofs on buildings.
  1. Benefits include that they move with the structure and do not absorb water. Bitumen is a hydrocarbon and is created from crude oil.
  2. The products have an extremely long life span, with most membranes having BS (British Standards) marks against each product name.
  3. There is low noise pollution during application.
  4. Bituminous membranes protect insulation and can reflect harmful sun rays. New products also contain photovoltaic cells that can produce solar energy.
  5. Bitumen is not water soluble, non-biodegradable

Asphalt or Bitumen

Asphalt, also known as bitumen, is a sticky, black and highly viscous liquid or semi-solid form of petroleum. It may be found in natural deposits or may be a refined product; it is a substance classed as a pitch. Until the 20th century, the term asphaltum was also used.

The primary use of asphalt/bitumen is in road construction, where it is used as the glue or binder mixed with aggregate particles to create asphalt concrete. Its other main uses are for bituminous waterproofing products, including production of roofing felt and for sealing flat roofs.

The terms asphalt and bitumen are often used interchangeably to mean both natural and manufactured forms of the substance. In American English, asphalt (or asphalt cement) is the carefully refined residue from the distillation process of selected crude oils. Outside the United States, the product is often called bitumen. Geological terminology often prefers the term bitumen.

Common usage often refers to various forms of asphalt/bitumen as "tar", such as at the La Brea Tar Pits. Another term, mostly archaic, refers to asphalt/bitumen as "pitch". The pitch used in this mixture is sometimes found in natural deposits but usually made by the distillation of crude oil.
Naturally occurring asphalt/bitumen is sometimes specified by the term "crude bitumen". Its viscosity is similar to that of cold molasses while the material obtained from the fractional distillation of crude oil [boiling at 525 °C (977 °F)] is sometimes referred to as "refined bitumen".

Thermal Insulation Prevents Heat From Escaping

What is thermal insulation?

Thermal insulation is the reduction of heat transfer (the transfer of thermal energy between objects of differing temperature) between objects in thermal contact or in range of radiative influence. Thermal insulation can be achieved with specially engineered methods or processes, as well as with suitable object shapes and materials. It can keep an enclosed area such as a building warm, or it can keep the inside of a container cold. Heat is transferred by from one material to another by conduction, convection and/or radiation. Insulators are used to minimize that transfer of heat energy. In home insulation, the R-value is an indication of how well a material insulates.

To understand widely, please follow the questions below:
  • Where is thermal insulation used?
  • How does insulation work?
  • What is the R-value?
  • What is the product for thermal insulation?

Where thermal insulation is used

If you have an object or area that is at a certain temperature, you may want to prevent that material from becoming the same temperature as neighboring materials. This is usually done by employing a thermal insulation barrier.

For example:
  • If the air outside is cold, you may want to protect your skin by wearing clothes that keep the cold out and the body warmth in.
  • If your house has cool air inside during the summer, you may want to prevent the temperature from becoming the same as the hot air outside by having the house well insulated.
  • If you have a hot drink, you may want to prevent it from becoming room temperature by putting it in a thermos bottle.
In any location specially in Saudi Arabia where there are materials of two drastically different temperatures, you may want to provide an insulating barrier to prevent one from becoming the same temperature as the other. In such situations, the effort is to minimize the transfer of heat from one area to another.

How insulation works

Insulation is a barrier that minimizes the transfer of heat energy from one material to another by reducing the conduction, convection and/or radiation effects.

Insulating materials

Most insulation is used to prevent the conduction of heat. In some cases radiation is a factor. A good insulator is obviously a poor conductor.
Less dense materials are better insulators. The denser the material, the closer its atoms are together. That means the transfer of energy of one atom to the next is more effective. Thus, gases insulate better than liquids, which in turn insulate better than solids.
An interesting fact is that poor conductors of electricity are also poor heat conductors. Wood is a much better insulator than copper. The reason is that metals that conduct electricity allow free electrons to roam through the material. This enhances the transfer of energy from one area to another in the metal. Without this ability, the material--like wood--does not conduct heat well.

Insulation from conduction

Conduction occurs when materials—especially solids—are in direct contact with each other. High kinetic energy atoms and molecules bump into their neighbors, increasing the neighbor's energy. This increase in energy can flow through materials and from one material to another.

Insulation solid to solid

To slow down the transfer of heat by conduction from one solid to another, materials that are poor conductors are placed in between the solids. Examples include:
  • Fiberglass is not a good conductor nor is air. That is why bundles of loosely packed fiberglass strands are often used as insulation between the outer and inner walls of a house.
  • Conductive heat cannot travel though a vacuum. That is why a thermos bottle has an evacuated lining. This type of heat cannot be transferred from one layer to the other through the thermos bottle vacuum.

Insulation gas to solid

To slow down the heat transfer between air and a solid, a poor conductor of heat is placed in between.
A good example of this is placing a layer of clothing between you and the cold outside air in the winter. If the cold air was in contact with your skin, it would lower the skin's temperature. The clothing slows down that heat loss. Also, the clothing prevents body heat from leaving and being lost to the cold air.

Insulation liquid to solid

Likewise, when you swim in water, cold water can lower your body temperature through conduction. That is why some swimmers wear rubber wet suits to insulate them from the cold water.

Insulation from convection

Convection is transfer of heat when a fluid is in motion. Since air and water do not readily conduct heat, they often transfer heat (or cold) through their motion. A fan-driven furnace is an example of this.
Insulation from heat transfer by convection is usually done by either preventing the motion of the fluid or protecting from the convection. Wearing protective clothing on a cold, windy day will inhibit the loss of heat due to convection.

Insulation from radiation

Hot and even warm objects radiate infra-red electromagnetic waves, which can heat up objects at a distance, as well as lose energy themselves. Insulation against heat transfer by radiation is usually done by using reflective materials.
A thermos bottle not only has an evacuated lining to prevent heat transfer by conduction, but it also is made of shiny material to prevent radiation heat transfer. Radiation from warm food inside the thermos bottle is reflected back to itself. Radiation from warm outside material is reflected to prevent heating cold liquids inside the bottle.

R-value

The R-value of a material is its resistance to heat flow and is an indication of its ability to insulate. It is used as a standard way of telling how good a material will insulate.The higher the R-value, the better the insulation.

Definition

The R-value is the reciprocal of the amount of heat energy per area of material per degree difference between the outside and inside. Its units of measurement for R-value are:
(square feet x hour x degree F)/BTU in the English system and
(square meters x degrees C)/watts in the metric system

Table

Insulation for the home has R-values usually in the range of R-10 up to R-30.
The following is a listing of different materials with the English measurement of R-value:
Material R-value
Hardwood siding (1 in. thick) 0.91
Wood shingles (lapped) 0.87
Brick (4 in. thick) 4.00
Concrete block (filled cores) 1.93
Fiberglass batting (3.5 in. thick) 10.90
Fiberglass batting (6 in. thick) 18.80
Fiberglass board (1 in. thick) 4.35
Cellulose fiber (1 in. thick) 3.70
Flat glass (0.125 in thick) 0.89
Insulating glass (0.25 in space) 1.54
Air space (3.5 in. thick) 1.01
Free stagnant air layer 0.17
Drywall (0.5 in. thick) 0.45
Sheathing (0.5 in. thick) 1.32
The R-value is proportional to the thickness of the material. For example, if you doubled the thickness, the R-value doubles.

What is Membrane Waterproofing?


Membrane Waterproofing
Definition

The application of a layer of impervious material, such as felt and asphaltic cement, to a foundation wall.

Types of Membrane Waterproofing:


Asphalt Membrane

    An asphalt membrane comes in a rolled sheet that builders place around the foundation's walls before they back-fill the area with dirt. The asphalt membrane is an elastic sheet that will cover small cracks if they develop in the foundation's walls. Asphalt membranes require protection boards to help keep them from slipping.

Polymer-Based Sealant

    Polymer-based sealants are chemicals that can be sprayed or painted onto the foundations walls. They are less effective as waterproofing membranes because they cannot cover cracks. They do work for many years, however, to keep the wall of the foundation free from water penetration.

Urethane Sealant

    Urethane is a synthetic substance that works well as a prevention and repair tool. Urethane-based sealants are simple to use. The chemical is thick and will help re-seal small cracks in the foundation.

Air Gap Membrane

    An air gap membrane requires more labor but works really well on all types of foundations. This sheet is polyethylene, which is a common plastic, and has small dimples throughout it. The dimples allow for air pockets and helps reduce the pressure against the foundation wall. After rolling out this sheet, the builders will attach it to the foundation, making it less likely to move around and become less effective.


What is Waterproofing?

Waterproof or water-resistant describes objects relatively unaffected by water or resisting the ingress of water under specified conditions. Such items may be used in wet environments or under water to specified depths. Waterproofing describes making an object waterproof or water-resistant (such as a camera or watch).

Waterproofing is used in reference to building structures (basements, decks, wet areas, etc.), watercraft, canvas, clothing (raincoat, waders) and paper (e.g., milk and juice cartons).

Waterproofing should not be confused with roofing, as roofing cannot necessarily withstand hydrostatic head, and waterproofing can.

The standards for waterproofing bathrooms in domestic construction have improved over the years, due in large part to the general tightening of building codes.
In building construction, a structure needs waterproofing since concrete itself will not be watertight on its own (but note concrete is easily waterproofed with additives). The conventional system of waterproofing involves 'membranes'. This relies on the application of one or more layers of membrane (available in various materials: e.g., bitumen, silicate, PVC, EPDM etc.) that act as a barrier between the water and the building structure, preventing the passage of water. However, the membrane system relies on exacting application, presenting difficulties. Problems with application or adherence to the substrate can lead to leakage.

Over the past two decades, the construction industry has had technological advances in waterproofing materials, including integral waterproofing systems as well as more advanced membrane materials.

Integral systems work within the matrix of a concrete structure, giving the concrete itself a waterproof quality. There are two main types of integral waterproofing systems: the hydrophilic and the hydrophobic systems. A hydrophilic system typically uses a crystallization technology that replaces the water in the concrete with insoluble crystals. Various brands available in the market claim similar properties, but not all can react with a wide range of cement hydration by-products, and thus require caution. Hydrophobic systems use fatty acids to block pores within the concrete, preventing water passage.

New membrane materials seek to overcome shortcomings in older methods like PVC and HDPE. Generally, new technology in waterproof membranes relies on polymer-based materials that are extremely adhesive to create a seamless barrier around the outside of a structure.

PVC Waterstops

INTRODUCTION

PVC Waterstops are used for providing water impermeability in expansion-contraction (structure) joint seen in concrete structures exposed to high & low water pressure and for preventing vibrations and deformations that would appear in concrete blocks.
Bitumat Waterstops is an internally cast PVC waterstop system manufactured in a range of sizes for use in reinforced concrete structures. It is essential to form a continuous waterstop network at all joints to prevent the ingress of water and it is vital to use factory produced fabrications. Bitumat Waterstops, internal flexible waterstop systems, have been developed for positive embedment in insitu concrete by creating a valve action to seal the water path, suitable for horizontal and vertical applications.

USES

  • Dams
  • Ponds
  • Canal lining
  • Water cisterns
  • Water refining facilities
  • Swimming pools
  • Deck
  • Construction tunnels
  • Hydro electricity & thermal plants
  • Bridges
  • Refining facilities
  • Metro constructions
  • Power plants viaducts
  • Supporting walls
  • Flooring settled on ground & foundations
  • Industrial structures
Bitumat waterstops serve as a barrier to the passage of water through, across, or along a construction joint in a concrete structure exposed to water on one or more surfaces. They are extruded from high grade PVC compounded with first quality plasticizers to form a pliable waterstop system.
They are:
  • Flexible
  • Strong and resilient
  • Weather resistant
  • Unaffected by low temperatures or constant immersion in water
  • Resistant to many chemicals found in the soil.
  • Easy to install
  • Accomodates joint movements while preventing eater movement through the joint.
PVC Waterstops

Forming & Positioning Requirements

PVC waterstops are installed prior to the initial concrete pour to ensure proper positioning. Split formwork is generally required for slab-to-slab, slab-to-wall joints where ribbed or dumbbell style waterstops are used. Split forms allow half of the waterstop to be positioned inside the first pour with the other half projecting into the second pour.

PVC Waterstop is easily butt spliced with a Teflon coated, thermostatically controlled splicing iron. The ends of the waterstop must be cut square to form matching edges. Uniformly melts the ends 380º using the thermostatically controlled splicing iron. It is important to use an indirect source of heat for this procedure. Direct exposure to a flame will change the chemical composition of PVC and result in a weak weld. When an 1/8" diameter melt bead develops on each waterstop end, remove the splicing iron and firmly press the two ends together in proper alignment. Hold until the material has fused and cooled. Allow the splice to cool naturally; do not quench. Melt temperature of the splicing iron must be maintained to avoid burning or charring the material. Heating irons haveresistance type heating elements and experience dimished performance if a reduced voltage is supplied. Avoid operating with long runs of small gauge extension cords.

Slab Joints

The Bitumat PVC Waterstop is supported in specially prepared split stop-end formwork which holds the waterstop in the horizontal plane to prevent displacement and folding so that half its width will be cast into the concrete approximately half way through the thickness of the slab.
Care must be taken to ensure that the waterstop is retained 'in the horizontal plane and that adequate compaction of concrete takes place below the web of the waterstop in order to avoid "honeycombing". Lifting the waterstop during compaction to release entrapped air will assist in forming dense compacted concrete. After stripping the formwork supporting the waterstop, the second half can be cast into the adjoining slab with similar precautions taken with regard to "honeycombing".

Wall Joints

The waterstop must be supported in split-end form work as described for slab joints, with great care taken to ensure that the waterstop does not fold over ufider the weight of the poured concrete. To eliminate fold-over, the waterstop should be wired to the reinforcing stee! using the wiring holes provided. A fully continuous waterstop network shall be formed using factory made junctions with site joints limited to simple butt welds between similar sections.

Bitumat BituTherm - Thermal Insulation


Click here to see product datasheet


The arid deserts of Arabia ensure that the scorching sun beats hard on the standing buildings during the day and then a thermal shock for the building in the night when the temperature drops to less than half. If you want your home to be warm in the winter and save on your heating bills, your insulation has one task... to keep the heat in! But if you want your home to stay cool on the warmest summer days, insulation's job is different... it must keep the heat out. How can one product do both? It's easy to understand once you grasp the simple concept of heat transfer.This daily occurrence takes its toll on the best of buildings if not suitably and adequately protected against the ravaging nature.

Heat flows naturally from a warmer to a cooler space. In winter, the heat moves directly from all heated living spaces to the outdoors and to adjacent unheated attics, garages, and basements wherever there is a difference in temperature. During the summer, heat moves from outdoors to the house interior. To maintain comfort, the heat lost in winter must be replaced by your heating system and the heat gained in summer must be removed by your air conditioner.

WHY INSULATE?

Heating and cooling account for 50 to 70% of the energy used in an average home. Inadequate insulation and air leakage are leading causes of energy waste in most home.
  • Reduce the consumption of electrical energy up to 40% during the cooling process inside the building.
  • Increases the level of comfort for the inhabitants in a building as it provides a cooler interior ambience.
  • The usage of AC is minimized. This helps to reduce the cost of power consumption.
  • Protects the building materials from the constant fluctuations in temperature thereby helping to enhance the expected life of the building.
  • Reduces environment pollution and the heat transmitted into the buildings.
  • Helps in preserving the national limited energy resources.
  • Thermally Insulated buildings have less noise pollution from the AC's & chiller rooms as also from the noise. penetrating from outside.

BITUMAT BITUTHERM

Produced in Dammam Saudi Arabia using the latest computerized state of the art technology, Bitumat BituTherm Extruded Polystyrene panels are specially formulated to suit the very harsh Middle Eastern climatic conditions. Bitumat BituTherm is an intelligent way to insulate a building.
Bitumat uses the most sophisticated German know how to ensure that the product is consistent, water resistant, reliable and able to maintain its high R Value for long periods. Bitumat BituTherm boards are made in a continuous skin surface & developed into a closed cell structure. Bitumat BituTherm maybe tested as per BS EN 13164-2001, ASTM C 578-95 or relevant DIN Standards.
The blended polystyrene polymer compound is heated, put through an extrusion process & exposed to normal atmospheric conditions so that the material will expand. The blended polystyrene polymer compound is heated, put through an extrusion process & exposed to normal atmospheric conditions so that the material will expand. The blended polystyrene polymer compound is heated, put through an extrusion process & exposed to normal atmospheric conditions so that the material will expand. XPS is available in several different densities and has an R-value at 75 degrees fahrenheit (24 degrees celsius) of about 5 per inch (25mm) of thickness.

Bitumat BituTherm can be used for Roofs, Walls or even Basement. Some salient features of BituTherm are:

  • Due to Closed-cell and homogeneous structure high resistance to water absorption thus ensuring that the product is not only dimensionally stable but capable of maintaining its K value for long periods.
  • Desirable resistance to vapor diffusion so that breathability is maintained.
  • Sufficient strength against heavy loads.
  • Excellent K and R values.
  • Long-term high insulation efficiency.
  • Resistance to ageing and rotting.
  • High resistance to thermal cycling.
  • Non Toxic and non hazardous to humans & environment.
  • Eliminates thermal bridging with its tongue & groove edges.
  • Available in various types for roofs, slabs, and walls.
  • Very light in weight with no additional load on the building.

APPLICATION ROOF

Bitumat BituTherm (R) can be very conveniently installed on a roof. In classical as well as Inverted roofs. It can be used with most roof membranes if appropriate precautions are observed. Once the waterproofing membrane has been installed and flood tested, the Bitumat BituTherm insulation boards can be installed loose laid or spot bonded to the waterproofing membrane. In protected roof membrane assemblies, ballast is applied after Bitumat BituTherm board roof insulation has been looselaid over the roof membrane. The amount of ballast will vary with the project's wind-uplift resistance requirements & thickness of the Bitumat BituTherm roof insulation board.

WALLS

Bitumat BituTherm (W) can be used as wall insulation also. It can be applied in several ways including as a sandwich application.

FLOORS

Heavy duty Bitumat BituTherm (F) can be used for floor applications also. The higher density and compressive strength makes it ideal for such applications.

MULTIPLE-LAYER INSULATION

NRCA's recommended specification is for multiple-layer insulation. Bitumat urges double-layer application, especially when the total required thickness of XPS insulation is more than 2 inches (50 mm).

STORAGE & HANDLING PROTECTION

During storage and handling, Bitumat BituTherm insulation materials should be protected from the weather & petroleum-based solvents, adhesives and direct contact with certain coal-tar products. Bitumat BituTherm insulation should be protected from direct contact with asphalt at temperatures more than about 250 degrees fahrenheit (121 degrees celsius), and it should not be exposed to flames or other ignition sources.

COVER WITH ROOF MEMBRANE

It is recommended that insulation boards be covered with a complete roof membrane by the end of each day's work. For protected membrane roof systems using Bitumat BituTherm insulation, it is suggested that the insulation be secured with appropriate ballast by the end of each day's work.

JOINTS

When double-layer Bitumat BituTherm insulation is used, the joints of the insulation boards in the top layer should be vertically staggered & offset from the joints in the underlying layer. The end joints of adjacent rows of insulation boards should be staggered, and the edges of abutting insulation boards should be in moderate contact.
