Installation Engineering of EPDM Membrane

EPDM membranes can be factory assembled from smaller width sheets by a hot vulcanising process, using suitable rubber-based adhesive or room temperature vulcanisable adhesive system, to form a higher width waterproof joint surface. Alternately, the individual sheets can be welded at site with the help of a proper adhesive system. 

As the EPDM membrane is elastic and tear resistant at low temperatures, the sheets can be manipulated over pipes and curves in any weather and can also be fitted properly around projections. 

For use on roofs, the surface of the roof or the substrate must be clean, free from debris, chipping or other materials prior to the laying of the built in sheet is necessary. If the surface is rough or uneven, an appropriate board sheet material can be used to provide a smooth surface. 

The following methods can be used for installation engineering of EPDM membrane  

Ballasting is an economical and quick system to secure an EPDM roof membrane. Waterproofing sheet is simply fitted over the flat roof or to a low slope, and covered with cleanly washed well rounded gravel with a diameter of 40-50 mm. Corners may be ballasted with suitable concrete slabs to prevent the sheeting from wind uplift and the perimeter can be fixed with contact adhesive.
