Permatec Substructure Waterproofing System
The Neuchatel Permatec Substructure Waterproofing system offers a “protected membrane” solution, typically utilizing a drainage board. It is fully bonded to the “POSITIVE” side of the structure, usually concrete, and combined with an Neuchatel Plasdrain drainage board, structural concrete, and backfill as required for performance. It should not be used on the “NEGATIVE” side of the structure, such as the inside of basements.
Neuchatel Permatec ECOwrap provides a flexible, fully bonded, and monolithic waterproofing system for flat or vertical substrate surfaces. Details like upstands, abutments, and penetrations are fully integrated into the Permatec system to ensure complete security.
For Substrate Waterproofing designs, the system may extend to the vertical surface of external walls in underground car parks and storage areas. It is advisable to include a vertical drainage board for drainage and protection, along with a drainage system at the base of the wall to allow for the free flow of accumulated water in the ground.
