Prokol Polymers UK were approached by one of its existing clients to look and provide a solution for long standing issue with water ingress to three asset tower block buildings on there flagship site. It was established from the brief and survey documentation over the years the key problem was failed expansion joint detail’s, this was on nearly all of the 2200 mm x 600 mm pre-cast external concrete panels. This issue was allowing water to ingress into resident’s properties causing internal damage and damp but more serious issues were around the building’s structural integrity. This problem was consistent over all three tower blocks on north and south facades.
The Planning & Site Set Up - Works Begin To Take Shape
Application Phase Two
Phase two consisted of further testing at higher and middle sections of the building as part of a belt & braces approach, further calibrated adhesion testing was carried out on the first south elevation block one before full seamless encapsulation was progressed.
The Final Seamless Hydrophobic Waterproof Memebrane
Finally the last phase of the application can be complete ready to seal the substrate and put back the original colour finish. The Prokol Polymers CE Certified Hydrophobic Pure Polyurea 136T seamless coating with 8 second cure was especially formulated to match the clients existing building colour and is fully UV stable, although glossy initially it is designed to matt to match in with the existing paint finish.
The CE Certified Pure Polyurea also has 330% elongation properties to allow for thermal movement or thermal shock and any building expansion & contraction demands there might be. The coating will also strengthen the building via conatinment and has high bond adhesion factors per millimeter.
Prokol Pure Polyurea Will Strengthen Brickwork by 75% & Concrete by 50%
The approved applicators work from a sophisticated computerised piece of spray equipment that is static and self sustained in a commercial van, the computer mixing the twin components competently then heats them to warm temperature (no hot works license required) and feeds them to a spray gun unit along 400ft of pre-heated flexible pipe, the Prokol CE Certified Pure Polyurea is then mixed at the end of the spray gun and delivered onto the required substrate. When the application has stopped the approved applicator team place the equipment on a recirculation mode which feeds the products separately back around the equipment resulting in zero waste.
Important Note: Prokol Hydrophobic CE Certified Pure Polyurea is Fully Inert has Zero VOC's (Volatile organic compounds) No odours manufactured using green chemistry and has full life cycle analysis.
