TBM PBF

TBM PBF is Plastomeric waterproofing membranes manufactured in an advanced continuous calendaring process by saturating and coating a synthetic carrier with a waterproofing compound made of a special grade of bitumen, which is modified with APP polymers. While the APP polymers enhance the thermal, mechanical, and aging properties of the membranes compound, the mechanical characteristics of TBM PBF is established by the non-woven continuous filament spun-bond Polyester which acts as the reinforcement that provides the membrane with its particular tensile strength, tear resistance, puncture resistance and elongation properties.

TBM PBF coated with PE (Polyethylene) film on the lower and upper surfaces and applied with an oxyacetylene burner.

USES

TBM waterproofing membrane are multi-purpose membranes for protected roofing & waterproofing applications subjected to different mechanical stresses and normal weathering conditions, and are recommended as a base layer in multi-layer systems in various application. TBM PBF products with higher reinforcement weights, respectively, accommodate applications with moderate, considerable, significant & critical mechanical stresses. TBM membrane series are particularly recommended for the following Applications.

  • Roofing or re-roofing works for sloped and flat protected roofs.
  • Waterproofing of underground structures
  • Waterproofing of wet areas, mechanical rooms and terraces.

APPLICATION

TBM PBF is usually applied by using a propane torch or a hot air generator as well as by mechanical fastening. It can also be applied using special adhesives in cold or hot applications. The substrate surface must be clean, dry, smooth, and free from any irregularities. According to the surface conditions, a coat of TBM Mastic primer required prior to the application of the membrane. TBM Product can be applied to the substrate fully bonded, semi bonded or loose laid, and the method of adhesion to the substrate shall be decided according to the waterproofing system design. Side laps should be from 8-10 cm, while end laps should be from 12-15 cm. For more info on application refer to application guide.

PACKAGING

TBM PBF, is launched into the market in rolls 1m wide and 10m long, with 3mm Thickness.

STORAGES & HANDLING

Rolls must be vertically stored in roofed-over spaces. If the rolls have to be stored outdoors for a long period of time, then they must be covered with a protective layer in order to protect them against the sunlight. If the rolls are to be stowed without pallets, they are not stacked one on top of another. In palletized stowage, two rows may be stacked one on top of the other.
