September 29, 2016 | Newtown square, PA

The challenge we faced was that it was a pretty tough pump dig, but besides that, everything went smoothly.

To address this, we installed a Grate Sump with an airtight lid, a 1/3 horsepower Fast Sump, and a built-in pump stand to capture groundwater seepage, with the discharge line running to the back of the yard.

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 challenge we faced was working in a finished basement. To address this, we installed a Santa-Fe system.

Marie C

August 08, 2016 | Drexel Hill, PA

Since it was a finished wall, it was not possible to see behind it, which made the leak harder to find. However, once the wall was cut, the leak was identified. To address the issue, we provided one wall of drainage system with a new pump replacement and a backup inverter for 24-hour protection.

Mallory B

The challenge we faced was that this basement had a wide footer, so we had to break out a little bigger than usual.

To address this, we installed a full perimeter drainage system along with a sump pump with water backup, and we dug the discharge line underground 10 feet away from the home for proper drainage.

Dave

August 23, 2016 | Havertown, PA

We provided a grate sump with drainage system along on pe wall we also cut the finish walls 4ft high and ran 4ft vapor barrier up the walls as well .

Project Manager Steve Custus recommended we install our ultimate Sump pump system 2 Basins one with an Half horse power pump , the other a 1/3hp pump combine they can handle close to 6 gallons of water per hour . Last but not least a Battery Back up inverter that can handle 2800 gallson per hour if the power was to go off ... Now the homeowners finally has peace in mind !

We replaced the clog part of her existing system then applied some outside damp proofing to prevent mud from washing in again.

Lizanne

October 10, 2016 | Drexel hill, PA

The challenges we faced were that we had a totally finished basement with carpet and everything, so our Senior Project Manager Steve first had to find the leak by starting with an outside water test to locate it.

Steve had seen this problem a few times before, so he knew how to approach it. After finding the leak, he recommended removing the lower portion of the wall. We then installed a new drainage system, parged the wall where the mud was washing into the basement, and tested the existing sump pump. Problem solved, and the homeowner was happy that she did not have to replace her entire existing drainage system.

Adam B

January 27, 2017 | Havertown, PA

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.
