Semi-Wrap Pipe Penetration Prefab

Scope of Application

Designed for wrapping pipe penetrations in TPO/PVC waterproofing membranes. Ideal for pipes that are too tall or have elbows, preventing direct membrane sleeving. The semi-wrap design allows two prefabs to be joined on-site around the pipe for complete sealing.

Technical Advantages

• Strong Adaptability & Flexible Installation: Accommodates pipes with diameters ranging from 80 to 160 mm. Can be trimmed on-site for a snug fit around smaller pipes

• Convenient Semi-Wrap Installation: Enables quick and straightforward on-site wrapping, significantly improving overall installation efficiency

• Monolithic Structure Prevents Cracking: Injection-molded as a single piece from homogeneous material, eliminating potential weld failure and leakage risks associated with overlapping P-class membrane seams
