Siplast Launches TeraPROOF Waterproofing System for Below-Grade Applications
The TeraPROOF portfolio includes pre- and post-applied membranes, liquid systems, and protection accessories—advancing Siplast’s goal of becoming a complete building enclosure protection provider.

Siplast announced the introduction of TeraPROOF, a full portfolio of high-performance materials for below-grade applications, engineered to create a robust waterproofing solution for commercial buildings. The materials support the company’s growth in becoming a complete building enclosure protection provider for its customers.
The waterproofing solutions include TeraPROOF Pre-Applied SBS Membranes and TeraPROOF STP Liquid Membrane, along with accessories such as TeraPROOF Protection CS1000 and TeraPROOF 10-11 Drainage Mat to complete installation. TeraPROOF systems are for horizontal and vertical waterproofing applications.
TeraPROOF Pre-Applied V-SBS and H-SBS Membranes are modified-bitumen, heat-weldable membranes for waterproofing applications. Designed for use in below-grade waterproofing systems before the placement of concrete, they consist of polyester mat impregnated and coated with SBS-modified bitumen. The top is surfaced with fine mineral aggregate and the bottom surface is coated with an SBS-modified bitumen adhesive layer specifically formulated for torch-lap sealing applications with a polyolefin burn-off film.
TeraPROOF STP Liquid Membrane is a liquid-applied, single-component, high-solids, flexible waterproofing membrane used in post-applied systems, such as concrete foundation walls, split slabs, inverted roof areas, planters, equipment wells, and other underground construction. It can also be used in detail flashing applications of pre-applied system applications, and used in conjunction with Pro Fleece for reinforcement of the membrane or detail areas.
TeraPROOF Protection CS1000 is a composite sheet (CS) utilizing a fleece-back and polymeric membrane. It is designed to protect the waterproofing membrane from puncture from sources such as compacted subgrade below pre-applied waterproofing, backfill damage on post-applied vertical waterproofing, or overburden elements in horizontal waterproofing assemblies.
TeraPROOF 10-11 Drainage Mat is a high-performance, two-layer drainage composite that ensures a continuous path for water discharge and relieves hydrostatic pressure buildup. It features a dimpled drainage core made of impact- and tear-resistant co-polymer polypropylene, fully bonded to a high-strength, needle-punched polypropylene Geotextile, allowing water to pass freely while blocking soil particles to prevent clogging.
“At Siplast, we are proud to offer TeraPROOF, below-grade waterproofing systems designed for both vertical and horizontal, and pre-and post-applied applications,” said Benjamin Meyer, AIA, NCARB, LEED AP, Building enclosure business Director, Siplast. “TeraPROOF is designed to integrate seamlessly with our premium roofing systems, vegetated and amenity systems, and above-grade wall systems. Our portfolio of TeraPROOF solutions offers exceptional protection from water intrusion for below-grade structures and enables critical building operations for the occupants.”
