The integration of GCP’s internationally recognised waterproofing technologies into the Saint-Gobain group has established a new benchmark for reliability within the African construction sector. Distributed through Chryso Southern Africa, these advanced membrane solutions provide engineers and contractors with a sophisticated toolkit for protecting both below-ground and above-ground structures. By leveraging high-performance materials engineered for demanding environments, the partnership ensures that local projects benefit from global innovation tailored to the specific rigours of the regional climate.
At the forefront of this range is BITUTHENE® 3000, a self-adhesive membrane specifically designed for critical applications such as basements and retaining walls. This product utilises a cross-laminated HDPE film paired with a rubberised asphalt layer to offer superior tear resistance and durability. For installations facing the challenges of colder weather, the BITUTHENE® Low Temperature Membrane provides an adapted adhesive formulation, ensuring that the ease of application and bond strength remain consistent even when ambient temperatures drop, thereby maintaining project timelines throughout the year.
The PREPRUFE® 120S system represents a significant advancement in pre-applied waterproofing, creating a permanent, fully adhered bond to poured concrete. This unique mechanical bond is essential for deep basements and tunnels as it prevents lateral water migration, ensuring the structure remains protected even if the membrane sustains minor damage during the construction process. Complementing this is the PREPRUFE® DLM detailing liquid membrane, which offers the same high-durability and chemical-resistant performance for horizontal applications and complex structural details, ensuring a seamless and robust envelope.
Andries Janse van Rensburg, Specialty Materials Head – Infrastructure BU at Chryso Southern Africa, emphasises the importance of precise application and material choice in modern civil works. He notes that these membranes are proven in projects worldwide and have been extensively tested in the harsh conditions often encountered locally. He further states that choosing the right membrane is critical to ensuring the service life and performance of a structure, and the technical team works closely with customers to specify the best solution for each application.
Ultimately, the synergy between GCP’s proven technology and Chryso’s local technical expertise provides the South African construction market with a dependable safeguard against water ingress. By offering comprehensive support from the specification stage through to final installation, Chryso ensures that contractors can avoid the significant costs associated with waterproofing failures. From large-scale civil engineering works to commercial developments, these solutions deliver the long-term integrity required for the continent’s growing infrastructure.
