Below Grade Waterproofing

Below grade masonry can be effectively waterproofed using the BarrierGuard System. This system provides a low cost and permanent mechanical seal against water ingress from hydrostatic pressure. Care should be taken to include waterproofing over the footing to assure wall and footing sealing. The BarrierGuard System should cover the underground surface and several inches above grade. BarrierGuard System should be applied from the outside. However, in some cases inside waterproofing is acceptable.

Curbs, Pitch Pockets, Roof Drains and Scuppers

These leak points require special attention to detail in flashing. These critical leak points must be well flashed with the full PremiumCoat System.

Note: Since many of these areas are heavy water collection points it is advised the BarrierGuard System be applied over the PremiumCoat System.

BarrierGuard will provide extra protection not only in water ponding conditions but also provide protection for water erosion areas. Please contact technical support for specific information.

Decks

Decks are roofs that you walk on and must be waterproofed with the complete PremiumCoat System. Special attention must be given to deck and wall junctions with Cant Strips. All posts, railings and walls must be treated. For increased protection, TrafficCoat abrasion resistant coating may be applied over the PremiumCoat System.

Flat Roofs

The entire field of flat roof can potentially leak and must be sealed using the complete PremiumCoat System. Care must be taken to prepare the surface by power washing and making any necessary substrate repairs before applying the PremiumCoat System. Ponding water conditions must be corrected at this time. And an attention to detail of all flashings and parapet walls is a must.

Fountains, fish ponds, planters, and retaining walls and other masonry structures that require waterproofing can be treated by the BarrierGuard System. There are many special applications that are difficult to waterproof but Hydro-Stop's BarrierGuard System works quite well. Please contact Technical Support for more information.

Gutters can be treated with the PremiumCoat System but the gutter must be pitched correctly. After proper preparation, including pressure washing and rust proofing using StableRust Primer, the PremiumCoat System is applied. Please contact Technical Support for more information.

Commercial metal roofs can be sealed by applying the PremiumCoat System over all leak points of the roof. Laps, seams, penetrations, skylights, screw heads and parapets must be sealed. Once the leak points have been properly flashed, the entire roof field is coated with two coats of FinishCoat. Proper preparation and priming of rusted areas with StableRust Primer is most important.

Parapets and Copings are part of the roof and are a major source of water intrusion. Water normally enters at the junction of wall and roof. It also enters from the top of the coping. The parapet wall can be completely sealed with the PremiumCoat System. Please contact Technical Support for more information.

Penetrations include any object that protrudes through the roof field. These are leak points and must be well sealed with the PremiumCoat System. Care should be taken to flash at least 6" up the penetrations and 6" down the penetrations. Please contact Technical Support for more information.

Skylights are flashed with the PremiumCoat System. The surface must be clean and the perimeter interface of roof and skylight must be completely sealed. Please contact Technical Support for more information.
