WATERPROOFING SERVICES

Balcony Waterproofing
Ensure that your balcony remains safe and sturdy year-round. If left untreated their supports can weaken and fall prey to serious deterioration. We can protect the structural integrity of critical surfaces.

Below Grade Chemical Grout Injection & Epoxy
If your below grade walls cannot be accessed for waterproofing, we apply chemical grout injection to get into hard-to-reach places. This is vital to create a chemical seal to stop water damage within cracks and joints.

Exterior Wall Coating
These coatings are durable, flexible, tough, and breathable, designed specifically to safeguard the exterior envelope of your commercial property from the elements.

Water from planters continually saturates a building's substrate. If you notice leakage, installing a protective system or replacing the damaged system is imperative, including sloping, drain and clean-out repairs, and root barriers.

Water Testing
Testing is the most effective way to pinpoint the source of a leak. We test for water infiltration and air intrusion, including ASTM* Diagnostic Tests, to determine the type of repair needed for the best return on your maintenance investment.
