Within the Saint-Gobain group, GCP’s internationally recognised waterproofing membrane technologies are setting the standard for reliability and performance in demanding construction applications. Across Africa, these solutions are available through Chryso Southern Africa, offering contractors and engineers a range of advanced products for below-ground and above-ground protection.

Among the leading solutions in the range are BITUTHENE® 3000 and low temperature membrane, PREPRUFE® 120S pre-applied membrane and PREPRUFE® DLM (Detailing Liquid Membrane) - each engineered for specific site conditions to ensure long term waterproofing integrity.

BITUTHENE® 3000 is a self-adhesive high-performance membrane designed for critical waterproofing applications in basements, retaining walls and substructures. It combines a robust cross-laminated HDPE film with a self-adhesive rubberised asphalt layer, providing excellent adhesion, tear resistance and durability. Its proven track record in both commercial and infrastructure projects makes it a go-to choice for challenging environments.

For projects where colder conditions can impact installation, BITUTHENE® Low Temperature Membrane offers the same reliable performance with a special adhesive formulation designed to allow easier handling and application in lower ambient temperatures. This ensures quality results year-round.

The PREPRUFE® 120S Membrane is a fully adhered, pre-applied waterproofing system that forms a permanent bond to concrete, preventing water migration and protecting against ingress even if the membrane is damaged during construction. This feature is particularly valuable for deep basements, tunnels and other below-grade structures where water pressure can be significant.

PREPRUFE® DLM (Detailing Liquid Membrane) has been developed to deliver the same pre-applied fully bonded performance in horizontal applications, offering high durability, chemical resistance and consistent protection for waterproofing details.

“These membranes are proven in projects worldwide and have been extensively tested in the harsh conditions often encountered locally,” Andries Janse van Rensburg, Specialty Materials Head ‑ Infrastructure BU at Chryso Southern Africa. “Choosing the right membrane is critical to ensuring the service life and performance of a structure, and our technical team works closely with customers to specify the best solution for each application. With these products, contractors benefit from both ease of installation and long-term protection.”

Through Chryso Southern Africa, customers gain access to not only the GCP range but also the technical expertise needed to ensure correct specification, detailing and installation - all essential for avoiding costly failures later in a project’s life.

From commercial basements to large scale civil works, the combination of Chryso’s local support and GCP’s proven technology is providing the South African construction sector with waterproofing membranes that deliver dependable performance in every application.
