Siplast Introduced TeraPROOF Waterproofing System for Below-Grade Applications

Siplast has introduced TeraPROOF, a range of high-performance materials curated for below-grade applications, offering a trustworthy waterproofing solution for commercial building utilities. This launch promotes the expansion of the company into a full-service building enclosure protection provider.

The TeraPROOF waterproofing solutions offers Pre-Applied SBS Membranes, STP Liquid Membrane, and accessories like Protection CS1000 and Drainage Mat 10-11, designed for both horizontal and vertical applications.

TeraPROOF Pre-Applied V-SBS as well as H-SBS Membranes are heat-weldable, modified-bitumen membranes designed for below-grade waterproofing. Made with a polyester mat coated in SBS-modified bitumen, they feature a mineral-surfaced top and an adhesive-coated bottom for torch-lap sealing, with a polyolefin burn-off film for easy application before concrete placement.

TeraPROOF STP Liquid Membrane is a high-solids, flexible, single-component waterproofing solution for post-applied systems, including concrete foundation walls, split slabs, inverted roofs, planters, equipment wells, and underground construction. It can also be used for flashing details in pre-applied systems as well as reinforced with Pro Fleece for added strength.

TeraPROOF Protection CS1000 is a composite sheet with a fleece backing and polymeric membrane, designed to protect waterproofing membranes from punctures caused by subgrade compaction, backfill damage, or overburden in horizontal and vertical applications.

TeraPROOF 10-11 Drainage Mat is a high-performance, two-layer composite that provides continuous water discharge as well as relieves hydrostatic pressure. It features a dimpled drainage core made of impact-resistant co-polymer polypropylene, bonded to a high-strength, needle-punched polypropylene Geotextile to allow water flow while preventing soil clogging.
