Water Proofing

Self-adhesive rubber asphalt compound with imported cross-laminated film and high performance formula to form high-performance, cold constructed, self-adhesive water proofing membrane.


Product specification
» Thickness 1.2~2.0mm; width: 1~2m;length according to design requirements.

» Excellent physical properties, especially high tear strength and dimensional stability; 
» Reliable bonding, easy to overhaul: firm bonding, any local damage to the coil, water will be limited to a small range, no turbulence.
»  Unique self-healing: It has unique self-healing properties, can automatically heal small cracks, and tiling roofs are more powerful.
»  Simple and quick construction: According to the site conditions, wet and dry paving can be selected, and the construction is simple  and quick. 
»  Unique wet paving technology, high degree of freedom of construction: wet or even without leveling the base surface can be constructed, not affected by the weather, the rainy season construction, the advantage is more prominent, is the most powerful "weapon" to protect the construction period


Scope of application
Mainly suitable for industries and civil in the basement, underground, square floors, roof gardens, terraces roof, etc

A brief description
» It is SBS (Styrene Butadiene Styrene) modified, torch-on elastomeric waterproofing membranes with fiberglass or non-woven spunbond polyester felt; 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).


Fields of Application
» It is used in curtain walls, foundations, and projects with high tensile requirements, basement walls, balconies, terrace roofs, inclined roofs, water tanks, manmade ponds, retaining walls, concrete channels as well as bathrooms and any wet surfaces.


Features and Benefits
» Applicable on different kind of surfaces at cold temperature because of high elastic property.
» Has high elongation and tensile strength.
» Resistant to aggressive effect of the soil.
» Easily applied to the details such as dilation,
» Edges of chimney and parapet returns.


Surface Preparation
» 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. Recommended to use B PR 100 Bitumen Primer is used as a primer before the application of membrane to accomplish 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.
