Foundation Crack Repair

One of the ways that water finds its way into your home is through small cracks in your foundation, as well as up through the floor in your basement. For many of these leakage areas, it is possible to fix the leak and stop the water from coming in. If we can catch a leak early, before the water has time to erode and expand the crack, the easier (and less expensive) the repair is.

Perma-Dry Waterproofing provides foundation crack repair in Bellevue, WA for small cracks and leaks. We use low pressure to inject the leaking area with either foam or epoxy. These materials are flexible, which works perfectly with your concrete basement as the concrete expands or contracts with the temperature and weather, allowing for a permanent, watertight seal.

Crawl Space Waterproofing

The crawl space is probably one of the most neglected area of your home in Bellevue, but it also one of the most important when it comes to air quality and keeping your home dry. Water can easily saturate the soil in your crawl space, leading to damp, poor quality air; dangerous mold and mildew growth; and water damage of your home or the items stored in the space.

At Perma-Dry, we utilize a variety of crawl space waterproofing techniques to address the specific, individual issues with your crawl space. Whether your wet crawl space is caused by any combination of seasonal groundwater fluctuations, cold weather condensation, rain drainage problems, and more, we tailor an individual solution that addresses the problem(s) at the source. These solutions include vapor barriers, sump pumps and other interior drainage systems, exterior drainage systems, Clean’n’ Dry Encapsulation liners, and more.
