Stone foundations leak as a result of failing masonry walls. Exterior water volume builds up and infiltrates the interior basement resulting in leaks.
Stone foundations constructed from 1600 to early 1920's were built using stone and lime mortar.
Best case scenario is that your foundation has one hundred year old mortar. That's a minimum of one hundred years of ground water softening lime and washing out bonding agents in the mortar and waterproof coatings.
Common causes of basement leaks are failing masonry, failing lime coatings, cracks, voids, loose stones, spalling bricks or aged sandy mortar in foundation walls.
At Thompson Crowley, we specialize in stone foundation restoration and waterproofing. The first step to any leak repair is masonry repairs.
We offer interior and exterior masonry repairs to prevent leaks and flooding.
Beyond basements leaking, aged mortar in foundation walls also causes structural concerns.
Failing mortar results in stone foundation bases moving, settling, sinking and cracking on the inside walls and exterior.
Stone foundation masonry restoration restores your foundation's masonry and waterproof coatings. It preserves and protects your foundation from leaks and any structural concerns with the added benefit of being waterproof.
