Foundation Repair and Basement Waterproofing In Grand Valley, ON Foundation Repair and Basement Waterproofing In Grand Valley, ON

In Grand Valley, Ontario, this basement has seen better days. The cellar had problems, and the homeowners wanted to renovate the basement to increase the property value. For starters, the basement walls started to bow inwards, leaving the foundation unsupported, which can eventually make the house collapse. With the weak walls, they started inviting water into the basement. The water would trickle down the block foundation and pool all over the basement floor leading the owners to constantly replace the soaked belongs, move everything around, and worry about mold buildup. With their options being limited, they decided to research and see their options to fix their basement permanently. 


After some research, the homeowners found Clarke Basement Systems to do the work. They had our experienced System Design Specialist, Ben Wallis, come to the home to show our new clients what work will be done and how much it will cost them. He suggested our GeoLock™ Wall Anchors to straighten the wall, UltraSump 4 for water circulation, ThermalDry® wall membrane to insulate the basement, and our WaterGuard® perimeter drainage system to reroute the water to the sump. On a later day, our Installation duo, Dustin and Alan, arrived at the home to start the work. The process took two days and made them less worried, knowing that the basement won't collapse and would remain dry.

Hi looking for a quote
Project Location: Grand Valley, ON
Hello, I have a cold cellar that hasn't been cleaned in over 8 years. Do you guys do this as well as check the insulation, etc?
Project Location: Grand Valley, ON
I am looking to have the triple safe pump installed at my house. I work 6 days a week and was hoping to have a quote done on Saturday afternoon or a Sunday if possible.
Project Location: Grand Valley, ON
We have a stone foundation that is letting in puddles worth of water into our basement when it rains. Last year we extended the drainspouts away from the house, but that clearly hasn't been enough. We think we need to do some work with grading but want someone to look at the exterior of the house before we do that.. we also wonder if we should be putting something like limestone mortar on the inside for extra sealing.
