Foundations with Limited Access? COLPHENE BSW is the Perfect Solution for You!

Posted by SOPREMA Experts on Aug 25, 2016 11:29:02 AM

Toronto, Montréal, and Vancouver are all examples of major Canadian cities where space is sometimes restricted on construction sites. In most construction projects located within large urban centres, access to the exterior walls of the foundation is difficult. Under these conditions, a high-performance pre-applied foundation waterproofing system must be used.

Watch the COLPHENE BSW video to learn more about the installation methods and unique benefits of this product.

 

 

 

COLPHENE BSW, the Ideal Solution!

The COLPHENE BSW system is the perfect solution when you’re waterproofing horizontal and vertical surfaces in blind side wall applications located in high-density areas. Its use is crucial when nearby buildings limit the access and excavation of a new project.

COLPHENE BSW membranes stand out from the competition due to their performance. One of the COLPHENE BSW membrane features is its adherence to cast-in-place concrete. Benefiting from the heat of the exothermic reaction that occurs during the curing process of concrete, the COLPHENE BSW system has superior adhesion due to the chemical and mechanical bond between the waterproofing membranes and structural concrete, which not only prevents water infiltration inside the building but also lateral water migration between the membrane and concrete.

BSW stands for “Blind Side Waterproofing”, because after the installation of membranes it will be impossible to have access to them once structural concrete is poured.

 

DUO SELVEDGE Technology, the Safest Choice.

Furthermore, for a safer installation, COLPHENE BSW H and COLPHENE BSW V membranes are provided with DUO SELVEDGE, a unique technology developed and patented by SOPREMA. This technology consists of providing an overlap of 100 mm (4 in) where the first 50 mm (2 in) of DUO SELVEDGE are sealed with a self-adhesive, and the other 50 mm (2 in) are then safely thermowelded or sealed with hot air.
