If water repeatedly follows a visible crack in a basement foundation wall, the crack may be providing a direct path from wet soil outside into the basement. Leakage often appears during heavy rain or snowmelt and may range from minor dampness to active dripping or water running down the wall

What is Hydrostatic pressure?
One critical component of any waterproofing system is removing water that accumulates around the footing and foundation. Otherwise, the water builds up, and under the pressure of its own weight, will pe*****te through the cracks and pores in the concrete walls and up through the floor slab. If there are any flaws in the waterproofing, hydrostatic pressure will ensure they leak.

Foundation cracks can happen for many reasons. During the construction of your home, the use of non-porous backfills like clay and organic matter will attract water over time resulting in foundation cracks during freezing and thawing; or if during the pour, the concrete was not properly cured, interrupted or not poured over properly tamped crushed stone

Even if your foundation was built perfectly, cracks could still occur. They might be hairline cracks, diagonal cracks, or horizontal cracks. The most common suspect for cracking is plain old water. The moisture of all kinds accumulates around the foundation causing the soil to expand. Cracks appear when the expanding soil puts pressure on the foundation walls and footings. Over time you may also spot hairline cracks, which are often harmless but should be monitored to ensure proper structural integrity.

Every long-lasting waterproofing system starts with one thing, access. Our crew is excavating around the home's foundation so we can reach the exterior walls and prepare them for a brand-new waterproofing membrane. It's a big job, but it's the best way to tackle water problems where they begin.

Why excavate the foundation? Because the most effective waterproofing happens from the outside in. Once the foundation is fully exposed, we can inspect the wall, make any necessary repairs, and install a continuous waterproofing membrane that helps keep groundwater out of the basement.

The name Lake Ontario comes from the Wendat word Ontari’io, which, appropriately, means “the lake is beautiful, the lake is big”.

The name is more than 400 years old, predating both the Confederation of Canada and the Declaration of Independence of the United States of America.

We know that America is changing. Their trading relationships, their foreign policies, their national monuments, their hydronyms.

Canadians also know that naming reality means calling it Lake Ontario – then, now and always.
