- SBS (Styrene Butadiene Styrene) Modified Bituminous sheet waterproofing is prefabricated elastomeric membranes that are reinforced with mats consisting of polyester, fibreglass or a combination of both reinforcement types. SBS modified bituminous membranes are available in varied thicknesses with specific physical properties to satisfy the demands of particual waterproofing conditions as well as surface finishes that facilitate various application methods.
- Composition
- Bituminous and modified bituminous flexible membrane systems are composite sheet membranes which are thermoplastic in nature but display variable elastomeric properties when modified. These sheets generally consist of bitumen (oxidized or modified), reinforcement, and surfacing materials. The performance of these membranes may be compromised by subtle, seemingly inconsequential changes in composition.
- The formulation of the bitumen is critical, particularly when its physical properties are modified by the addition of polymers. Bitumen is most commonly modified with styrene butadiene styrene (SBS). The manufacturer must ensure that a suitable degree of compatibility exists between the bitumen and the polymer and that a thorough mix has been obtained. The careful selection and combination of bitumen and polymer (the type of modifier, the percentage of polymer used, etc.) determines the physical properties and long term performance of the modified bituminous "binder". The binder provides the membrane with its waterproofing capability and may impart the following properties:
- low temperature flexibility
- elasticity
- high temperature resistance to flow
- resistance to aging
- The bitumen utilized for oxidized bituminous membranes has been "blown", similar to roofing asphalt. This produces a higher softening point and, therefore, a more useful temperature range.
- The physical properties of the binder are further enhanced by the imposition by saturation or coating onto a carrier or reinforcing mat, most commonly a textile such as:
- non-woven spun-bonded polyester
- woven polyester scrim
- fibreglass mats
- woven fibreglass cloth
- combinations of the above.
