Waterproofing Membranes / APP or SBS Modified, Bituminous, Anti-Root Membrane
It is APP (Atactic Polypropylene) or SBS (Styrene Butadiene Styrene) modified, special anti-root additives content, torchon plastomeric or elastomeric waterproofing membranes with non-woven spunbond polyester felt; both sides are coated with polyethylene film.
Fields of Application
It can be applied to structural details of gardens, terraces and terrace roofs, and it eliminates the risk that plant roots damage through the waterproofing coating.
Features and Benefits
- Flexible and long lasting.
- Easy to applied on different kind of substrates.
- Has high elongation and tensile strength.
- Resistant to aggressive effect that may come from the soil.
- Easy to applied on dilatation, edge of chimney and parapet returns.
Application substrate should be cleaned off loose pieces, oil and other chemicals. Surface defects are repaired with the suitable REPAMERK repair mortars, corners are chamfered with PH 55 bitumen fillet tape. Before the application B PR 100 Bitumen Primer is applied as a primer to obtain better finish.
10 cm overtopping shall be allowed for joints and 15 cm overtopping for ends by using welding torch. The surface coated with mineral stone on joints should be heated and minerals should be buried in to the bituminous surface by using trowel before welding the joints together. The transverse joints of the first layer covering should be laid down in an offset position. For the top layer, longitudinal and transverse joints of the first layer should be centered. Roof covers should be laid perpendicular to the slope from the point where the slope is lowest.
