At Worthington Waterproofing, we are certified basement waterproofing specialists who go the extra mile to install a lasting water drainage system in your crawl space. Our crawl space waterproofing system is roughly the same for any area of your Delaware Valley home, including the basement. We’ll dig out a 15″ – 18″ trench for a French Drain and install a sump pump to send collected water outside. This system works continually to keep your crawl space dry and clean.

Here’s how we do it:

• Our experts jackhammer the cement floor next to your foundation walls to remove the cement and dig a trench around the interior. These trenches can go as deep as the bottom of the footer.
• We line the bottom of the trench with geotextile fabric to prevent animals and weeds from coming through. We also pour a 2″ – 3″ layer of Pea Gravel on top of the fabric.
• We’ll lay a 4″ perforated PVC pipe on top of the Pea Gravel, and we fill the trench with 3/4″ of clean crushed stone.
• The contractors lay a piece of MiraDRAIN drainage board roughly 6″ wide over the trench, and bend it roughly 6″ up the wall.
• Our team installs HDPE sheeting approximately 18″ up the wall and lay it over the MiraDRAIN for complete crawl space encapsulation. We seal the HDPE to the wall to prevent any water vapor or Radon from escaping into the basement.
• We re-cement over top of the trench and bring it back to the original floor level.

This drainage system collects moisture as it drains into the PVC pipe and funnels it to a ‘crock’ that is roughly 22″ wide by 24″ deep. Inside the crock is a heavy duty, cast iron, commercial-grade sump pump. Worthington Waterproofing uses Champion Pumps and Rich Tech sump pumps for most of our projects. These are available with anywhere from 1/3 horsepower (HP) up to 1 HP.
