PVC waterproofing membrane construction process
1. Prior to commencing construction, it is essential to clear any debris and refuse from the primary floor surface. The foundational layer must be thoroughly cleaned, ensuring that no sharp objects are present.
2.Apply the polyethylene film, overlapping it and securing it with a self-adhesive strip for the next phase of construction.
4. For the pre-PVC waterproofing membrane, position the PVC membrane according to the designated line control points on the insulation layer, ensuring that the laying direction aligns with the orientation of the pressure plate’s corrugation.Lay the PVC membrane flat and loose over the insulation, keeping it straight and untwisted. Trim the 120mm lap width as needed.
8. The final step involves securing the PVC waterproofing material at the head, fastening it with a bead, and sealing it with an appropriate sealant.
