My father, Don purchased Elyria Pressure Seal in 1974 and I proudly purchased the company from him when he retired in 1987.

Our market area quickly expanded from the west side of Cleveland to include all the Cleveland, Akron, Canton, Painesville areas, as well as Put-In-Bay. Since Elyria Pressure Seal’s inception back in 1967, we’ve sealed over 43,000 foundations – all of them with our time-honored commitment to customers:

“Residential jobs will be serviced within 24 hours of when they are ready.”

In 1987 Elyria Pressure Seal recognized the need for foundations that where both dry and warm. Working with waterproofing and insulation manufacturers we pioneered the Waterproofing and Insulation – Protection Board concept which most builders use today.

We use a variety of quality waterproofing and Insulation, Protection and Drainage Boards and can customize warranty lengths from 10 Years to Lifetime to fit your needs.


Bone Dry Waterproofing began operations in 2004 to serve the Columbus and surrounding area. We have consistently grown our market share and offer this market a variety of Waterproofing, Insulation, Protection and Drainage Boards, Crack Injection and other residential and commercial services.
