We have a horizontal crack in our basement (does not leak and is not bowed). The lower half of the basement is poured and the upper is brick. It is the brick area that the crack is located.

Water coming in through basement floor.
Vicinity of Locust in Welland
Have a crack in my basement, leaks with heavy rainfall
Vicinity of Grange Ave in Welland
Whenever the ground is saturated we have water coming up through the basement floor at the first step, has only been an issue in the spring and with all the melt and heavy rain this year it's getting worse.
Vicinity of Wallace Ave S in Welland
Recent sump pump overflow. Could not keep up with the rain fall. Some water damage inside. Waterlogged yard, looking for solutions to dry existing damage and prevent further incidents. Looking for someone to come out as soon as possible.

Small leak in basement
Vicinity of Carlton Ave. in Welland
The attached single car garage walls are cracking due to the foundation settling. I think the footings may not be deep enough to support the brick covered block walls. The walls of the house itself over the basement are not cracking.
Vicinity of Hatter Ave in Welland
Foundation walls cracked, crumbling in some areas, bowing one one side of the house. No basement, crawl space
Vicinity of Charlotte Crt in Welland

Moisture in basement wall from leak
Vicinity of Mcmaster Avenue in Welland
My house has a block foundation, with at least 1 leaky spot that becomes very wet when it rains. The main beam support posts are also in rough shape from what looks like a poor repair by the previous owner (old wooden posts combined with non permanent steel columns) drywall upstairs is cracking and there is a noticeable slope in the floors.
Vicinity of Harold Ave in Welland
My basement has an area that gets wet when it rains but I can never tell where the water is coming from. The baseboards for the basement washroom are ruined by this moisture. Also my sump pump sometimes floods when it rains a lot. Please help!
