The Quadrangle

November 30, -0001 | Haverford, PA

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.

Jamison Basement Waterproofing installed a full perimeter Grate -Drain (Closed) DrInage System to protect all 142 linear feet of their basement from water intrusion. Also installed was the patented freeze stop system which will prevent their basement from flooding should the exterior pipes ever freeze up in the winter time , The homeowners were also concerned about what would happen should a hurricane or other extreme weather event happen in the area again. To ensure that the basement would never flood even during power outages, Jamison Basement Waterproofing installed 2 sump pump which has a battery Inverter for 24-hr protection . Dave the Project manager also recommended several Inspection ports so that the homeowners could move their high volume dehumidifier from location to location without ever having to empty the water and to make inspection of their system in the future very easy for future annual service. Crew Foremen : Steven Custus and crew went over and behind to wow this client.

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.

The challenge we faced was that it was a stone foundation, and nothing is easy when trying to make an opening in an 18-inch-thick stone foundation wall. Each stone had to be removed one by one by a stone mason.

To address this, we installed a new egress window that is up to code for a secondary exit out of the basement. Now Chris can finish the basement and does not have to worry about the safety of his tenants if they ever need to exit out of the basement.

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

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.

The basement wall crack had an active leak for some time, so it took a little longer to stop the crack from leaking, especially because it had rained just a day before the installation.

To address this, we replaced the existing sump pump that had burned out with a new Fast Sump. We also repaired the leaking foundation wall crack. Now the homeowners can put their home on the market without the fear of losing resale value due to basement waterproofing issues.
