Fixing a Gravel Filled Crawl Space in Essex County, ON

Problem: Many homeowners believe that putting a layer of gravel in their crawl space will solve the water and moisture problems. This isn’t true and doesn’t work. 

Gravel is porous and it does not stop water from moving or collecting.

Fixing a crawl space with a gravel floor presents two challenges:

  1. It is difficult to dig trenches and create drains to properly direct the water out of the crawl space compared to dirt.

  2. To further keep the humidity level acceptable and encapsulate the space, a very heavy duty liner is required, as the liner will be more prone to rips and tears with the rough gravel below it.


  • Our experienced team members were able to create trenches and drains to effectively move the water into the crawl space sump pump.

  • Our CleanSpace®️ Liner is super heavy duty and durable enough to withstand the rocky floor encapsulated below.

If you have a challenging crawl space, please reach out to us for a permanent solution: 1-844-320-1542

I have a leak through the foundation in the basement. Not sure where it is coming from. I already disconnected the downspout in the spring which seemed to resolve the issues in that area. But now the last two rain storms there has been water seeping in the cracks of foundation on the outer wall in the one room in basement. Looking for someone to assess and get a quote. Thank you

I have a smell in my crawl space that gets passed through the house through the furnace vents. I suspect it may be sump pump smell but I'm not certain. I need someone to come in and inspect the sump area and identify the smell and alleviate it if possible. Your speed reply would be greatly appreciated. Regards, Sally
