Bituroll
Fibreglass Reinforced Membrane
Bituroll is a polymer modified bituminous waterproofing membrane, manufactured from a mixture of bitumen and selected polymers, which are blended together to obtain good waterproofing properties. The bitumen compound also exhibits high heat and UV resistance properties. The polymerized bitumen is coated on to a dimensionally stable reinforcement core of non wovwn glass fibre carrier.

Products
Modified, torch-on waterproofing membranes with fiberglass, both sides are coated with polyethylene film or one side coated with polyethylene film, the other side is coated with silica sand, aluminum foil or natural or colored slate chippings (mineral stones).
Properties
This material has the ability to retain its shape after being stretched and therefore, is widely used in modified bitumen roofing, coatings, sealants and paving amongst other applications.
Waterproofing
Excellent resistance to positive water and vapour pressure.
Fiber Glass
More resistance to moisture due to the porosity of the sheets.
UV Resistance
Membrane is exposed to the sun, it must be resistant to UV rays.
Torch Applied
Long life span due to its tightness of membrane against the surface.
Heat Resistance
High resistance to mechanical damage and puncturing.
Flexible
Good flexibility. Can accomodate structural movements.
Rolled
Good dimensional stability under tension.
Environment Friendly
Developing new and alternative technologies.
Harmless
Resistant to water borne chemicals.
Area of Appllication
Bituroll is used as waterproofing membrane on the folllowing structures:
- Inverted roofs and parapets
- Terraces, balconies and patios
- Sunken slabs
- Bridges and tunnels
- Airport aprons and ramp areas
Bituroll membranes in tropical regions can also be used for waterproofin of below ground concrete sturcture like:
- Concrete foundation and footings
- Basements
- Pile heads
- Swimming pools and water retaining structures(externally)
