Waterproofing (SpraySeal)

SpraySeal is a highly versatile elastomeric coating that is cold-


applied using a spray-on system. It can be used to cover a wide variety of surfaces both indoors and outdoors. With its unsurpassed ability to expand and contract, it can easily withstand all weather conditions.

Waterproofing must be able to accomplish three goals when we are considering it to be a foundation protector. Firstly, it must stop water vapor, the gaseous form of water that can be released by the surrounding soil and can move through concrete. Secondly, waterproofing membranes must be able to stop water under hydrostatic pressure. Finally, and being a characteristic unique to NaturaSealís waterproofing system, is that waterproofing must be able to span a crack in treated concrete.

Our waterproofing system accomplishes these three goals. With the ability to build up ones waterproofing protection layer to any desired thickness and when installed properly by our certified applicators, you are left with a protective membrane that is elastic, flexible in nature, self healing, and can withstand hydrostatic pressure.

Waterproofing is essential in areas where there is significant rain and/or high water tables. As water enters the ground, it collects around the foundation. The higher the water rises up the foundation, the greater the hydrostatic pressure is exerted against the concrete surface. This is especially true in areas with clay soils, as clay will absorb and hold more water than granular soil. This hydrostatic pressure forces water through porous concrete. Therefore, the sub-grade depth of the concrete structure, the degree of inherent hydrostatic pressure in the area, and the use of the interior space are important criteria to consider when determining whether damp proofing or waterproofing is appropriate.
