We installed a new liner, lid and pump at this sump location in a St. Thomas home. There was also floor-wall joint seepage present, so we installed our WaterGuard drainage system, which takes groundwater seepage to the sump pump. Our ThermalDry vapour barrier in seen on the walls. 

Great work Jefferson, Jose and Nathan!

Problem: An unfinished cold storage area is a great place to store items to keep cool, such as canned food, even in the warm summer months. Although closed off from the rest of the house, if there’s water penetrating any area, it creates a damp, humid and unhealthy environment which affects the entire home in what is known as “The Stack Effect”.    

Solution:  We installed a French drain system on the problem walls in the cold storage area, added a powerful sump pump with a battery backup for improved drainage and reliability and finished it off with our BrightWall® rigid basement wall system. Now this cold storage area is dry, heathy and will look fantastic for years to come.

Problem:  Even newer homes can have problem basements. This basement often felt damp and smelled musty. Excess water vapour was entering the space from the unsealed sump pump lid.

Solution: To help control humidity, we installed the super quiet and efficient SaniDry™ Sedona Dehumidifier. It’s connected directly to their updated sump pump system, so with regular maintenance, these homeowners will never have to worry about excess moisture or a damp feeling basement again.

Any lid on a sump pump which is not sealed to the slab is not airtight. The lid to the right in this photo has a slot to allow it to be put in place around the discharge line. Other than preventing some objects from falling in, it servers very little purpose.
Radon Mitigation and Sump Lid - St. Thomas, ON
In the unfinished area of the basement, we created an in-floor drain which effectively moves any and all leaking water into their new heavy-duty sump pump system. We then finished the floor with fresh concrete. This area is now a clean and dry space for storage - just what the homeowners wanted!

Job Stories From St Thomas, ON
Radon Gas Solution in St Thomas, ON

Radon Gas will seek any opening in a basement to enter the home. The air pressure in a basement is usually lower than the outside as air will migrate to the upper levels of the home during the heating season.

 

Cracks in the floor and walls are one of the main culprits to let radon gas into the home. Advanced Basement Systems wall called to a home in St Thomas, ON after the home owner found high levels with proper testing. Large cracks under the carpet were discovered during the inspection. The mitigation included repairs to the cracks and a proper powered vent system installed.

 

The home is now testing lower levels of Radon gas and is safe for the home owners.

Old house, damp basement. Water enters basement through cracks after rain and winter. Looking for economical solution. Can be available for on-site review Thursday Aug.28

I have a bump out that I found wasn't insulated properly, probably since the house was built. It wasn't sealed off from the basement so there is easy access for it to be sprayed so I was just wondering what the cost would be.
