Saint Gobain Chryso Pre-applied Self-adhesive Florprufe 900 membrane  . 

One single product for preventing rising dampness as well as preventing termites, rats and red ants from entering into the blockwork/brickwork.


CHRYSO PREPREUFE DPC is a pre-applied self-adhesive HDPE based DPC membrane manufactured with ROTERPROOF™ technology for protecting the structure from water ingress, rising dampness, termite attack, rodent and red ant attack. 

 Prevents rising dampness from entering into the building floor area, thereby protects the structure from the hollowness or debonding of tiles/granite/etc.  Prevents the growth of termites.  Prevents the attack of rats and red ants.  Fast and easy application.  Excellent Resistant to acid, alkali and aggressive ground water conditions.  Can be applied over rammed/consolidated earth. 

Self-Adhesive Waterproofing Membrane is a cold-applied, flexible sheet used to protect surfaces from water ingress. It is composed of a rubberized bitumen adhesive layer laminated with a protective film (HDPE, aluminum, or polyester), which adheres directly to the substrate without requiring heat or open flame.

�� Technical Specifications (Typical)

HDPE (High-Density Polyethylene) Membrane Waterproofing is a premium solution used to protect basements and underground structures from groundwater ingress, hydrostatic pressure, and moisture-related damage. It provides a flexible, durable, and chemical-resistant barrier, ideal for both new construction and repair projects.

🧰 What is HDPE Membrane?

An HDPE membrane is a pre-formed sheet composed of tough plastic (HDPE), often layered with adhesive or bonding agents. It offers excellent tensile strength, root resistance, and low permeability, making it suitable for permanent below-grade waterproofing.
