Waterproofing a Box Gutter

Box Gutter Waterproofing is specialized. More than 90% of commercial/industrial Roofs have Box gutters that are designed to redistribute water away from roofs.  Most commercial landlords experience the complete opposite.  Blocked gutters can pool water in gutters causing them to rust and allow water to ingress.  This water leaks destroy masonry compositing  and building structure integrity including.  Leads from Box Gutters are known to destroy product or work environment is under the roof.

Projects

Tygervalley Centre

Waterproof Lab was contracted to seal a leaking box gutter above one of Tygervalley Centre’s anchor tenants. The failed waterproofing was removed and replaced with EPDM - a strong advantage of using this waterproofing system in this application was the waterproof membrane’s high UV resistance to the strong African sun and the fact that we could terminate the membrane against the vertical wall of the parapet with aluminium termination bar.

Firestone RubberGard EPDM would be highly recommended as the best advice to solve your problem. The beauty about using this system is that there is NO pap and lap.  The membrane is factory cured and we adhere a rubber membrane all alongside the upstand and length of your gutter.  Most time we will seal an entire 30m length gutter with rubber membrane and no seems hence reducing the risk of membrane join leaks (See below for application advice);

 Most waterproofing systems on the market do not cater for the African Sun high UV.  Also most systems cannot take pooling water. Firestone RubberGard EPDM meets both criterias making it a most superior waterproofing system for your Roof Gutter.  Please see explanation, below;

EPDM is a strong, highly flexible rubber membrane, with minimal seams (joints) which is designed as a reliable medium for sealing gutters & many other waterproofing problems.

(See methodology below);

In some instances this might be necessary. However, in most cases depending we recommend unscrewing the roof sheets from the purlins and tucking the Waterproof Lab RubberGard membrane under and refastening the screws.  This eliminates the necessity to go through the expensive procedure of removing your roof and gutter.  In short Waterproof Lab’s Firestone RubberGard membrane will save you thousands if not hundreds of thousands of rands in a case of a big roof.

This is a simple procedure, which is covered In detail in the methodology below;  Also see the videos on Waterproof Lab’s website
