Project manager Steve recommended a closed sub floor Drainage system called GrateDrain to redirect water from under the basement floor at the floor wall joint to the new GrateSump , the GrateSump can remove up to 2400 gallons of water per hr from the Basement. Steve also recommended a high volume dehumidifier to eliminate the high levels of moisture in the basement and to eliminate the homeowners fear of mold. Crew Foremen Dwight C Project Manager Steve C

The challenges we faced were that it was a very large basement, requiring around 240 feet of drainage system with a full vapor barrier and 3 sump pumps. Another challenge was that the floor in the lower basement was very hard to jackhammer in order to install the system.

To address this, we installed a full drainage system with a complete vapor barrier and 3 sump pumps.

Project Manager Steve Custus went out and solved this problem a few 100 times before so he knew exactly what to recommend. He recommended a window well drain that would catch any water inside the window well before it reaches the window and channel the water in the grate drain drainage system below that will channel the water to the Grate Sump .

This was a tough job because we had to do all the waterproofing from the exterior. Another challenge we faced was that a concrete slab was in the way, so it had to be removed and put back by us in order to complete the installation. To address this, we installed a below-grade dampproofing solution with tar and membrane on the outside of the foundation wall.

Senior Project Manager Ed Went out to sit down with the clients to hear about all their concerns with their basement. Ed recommend the homeowners reduce the relative humidity in the basement by bring it down below 50% this would make the basement more comfortable and preventing mold growth at the same time . Ed explain how important it is to choose the right size dehumidifier , because of the size of the basement Ed recommended the compact model dehumidifier that covers up to 1700sq . We also closed up the open Sump pit that was humidifing the air with tons of moisture. Last but not least we replaced all the old leaky windows in the basement , because it’s key when trying to condition the air in the basement you keep all outside air out of the space.

Project Manger Steve Custus went out and met with the investors . He recommended a Grate- Sump basin with a built in pump stand , air-tight sump lid with a floor drain and because of the high water levels he recommended a higher capacity Sump pump with a dual float switch to ensure them they won't have another issue when it comes to the Sump pump.

I had water soaking my finished basement floor after recent storms and called to get a free inspection; the company scheduled someone to come out to evaluate and discuss solutions like French drains, sump pumps, or concrete repairs.
