Sump Pumps Before & After Photos

The groundwater seepage from this crawlspace had resulted in mold affecting the surfaces of the wooden structural elements and paper-faced insulation in the subfloor & walls. We removed the insulation and cleaned the structural elements - drying them & coating in a white breathable EPA registered fungicidal coating. In order to prevent this from happening again - we installed a drainage system gravity fed to a SmartSump Pump System to pump water to the exterior and away from the foundation. We also added Drainage Matting, Terrablock Floor Insulation, & sealed 20 mil antimicrobial & cord reinforced liner to the earth and walls for a true CleanSpace Encapsulation System. We air-sealed perimeter rim penetrations and reinsulated. This crawlspace is warranted to be free from minor damage to the liner and ground water on top of the liner for 25 years!

Sump pumps fail over time. Most of the time we can replace them with a SmartSump Pump System: a 1/3 HP M53 Zoeller cast iron pump, which is placed in a deep and durable liner with an airtight lid with an airtight floor drain, CleanPump Stand, and battery powered WaterWatch Alarm System.

The liner is installed into stone and sits flush to the grade of the Earth floor. The 1.5” discharge line runs through the rim to the exterior. The exterior discharge line includes an IceGuard to prevent ice buildup, 10’ of 3” PVC discharge line buried several inches for grass to grow over it, & a LawnScape Outlet to allow gravity to expel water and help prevent debris from entering the discharge line. This unit pumps 2,580 gallons per hour at a 5’ head. After tying in the CleanSpace Crawlspace Encapsulation System into the top of the liner and tightening down the lid - This crawlspace is protected from the devastating effects of groundwater seepage - had it been left unchecked, structural damage most likely would have cost the homeowner 10x more sometime in the future. Looks good & functions great!
