At Diamond Masonry & Waterproofing, we provide solutions that are tailored to the specific challenges your Plainedge property faces, whether it’s high groundwater, runoff from heavy rains, or poor drainage grading.
When it comes to basement waterproofing, french drains are very important. Installed around the perimeter of your home, either inside or outside, these systems collect groundwater before it can reach your foundation and safely guide it away.
When water gets under your home, a sump pump takes care of it. These powerful pumps automatically activate when water levels rise, pushing moisture out and away from your foundation.
Even small cracks in your foundation walls or floor can cause big problems over time. If not addressed, they allow water to seep in, leading to mold, structural damage, and expensive repairs.
Water that pools on driveways, patios, or walkways near your home can easily end up in your basement. Grated channel drains are designed to quickly capture surface runoff and direct it away from your foundation.
For homes that need extra protection, applying a waterproof membrane directly to the exterior foundation is one of the most reliable long-term solutions.
The slope of your yard can contribute to basement leaks. If the ground around your home slopes towards the foundation, it’s funneling water where you don’t want it. We can regrade the area around your home to improve drainage and prevent erosion.
Basement windows are often a weak spot for leaks, especially if water is collecting in the window wells. Our window well drainage solutions divert water away, keeping the window area dry and sealed all year long.
