Take a look at this wet basement transformation. This basement was flooding and water was leaking through the stone walls. The wet basement was causing a musty smell throughout the whole house. We waterproofed the basement, installing a french drain around the parameter along with a SuperSump sump pump to drain out any water. We also installed a CleanSpace liner along the walls to direct all moisture into the french drain and then into the SuperSump sump Pump. This solution is permanent and comes with a lifetime warranty.

Look at this sinking concrete along this the sidewalk in Downingtown, PA. Uneven concrete is a huge tripping hazard. PolyLevel is the perfect solution and is a great alternative to total concrete replacement. With our PolyLevel system concrete is permanently lifted and stabilized. This sidewalk was ready to be used only 15 minutes after the injection. We also caulk to points around the concrete to prevent future erosion.

PolyLevel™ Concrete Leveling & Lifting

The sunken and cracked concrete in your garage, basement, or around your Downingtown home is both an eyesore and a safety hazard. It is also likely to get worse, but we can fix it for you.

Our experts use PolyLevel, a superior polyurethane foam. Small holes are drilled in the concrete, the foam is injected and the expanding foam lifts the concrete. The majority of contractors you will call use mudslurry instead of foam. Mudslurry is heavier, require larger holes in the concrete and does not last as long as PolyLevel. Call us today to learn more.

We Fix
  • Cracked Driveways
  • Uneven Patios
  • Sinking Sidewalks  
  • Sinking Basement & Garage Floors        

  • Tilted Concrete
  • Sunken Pool Decks
  • Highway & Commercial Issues


Job Stories From Downingtown, PA
Concrete Repair in Downingtown, PA

These homeowners in Downingtown, PA finally decided to call us after years of visitors tripping on their walkway. Sinking concrete results in major tripping hazards and these homeowners realized this first hand. Sinking concrete is also an eye sore and lessens the curb appeal of your home. These homeowners knew they needed to repair this concrete walkway so they called us!

When we arrived we knew that our PolyLevel system was the perfect solution for this sinking concrete. Our PolyLevel system lifts and levels sinking concrete by filling the void between the eroded soil and the concrete slab. The lightweight polyurethane foam turns from a liquid to a solid, fills the void, and then solidifies and permanently stabilizes the concrete creating a flat even surface on top and eliminating all tripping hazards. After the concrete is lifted and stabilized we apply caulk to the joints to seal and prevent future moisture from seeping under the slab. The process is noninvasive and cost efficient.

These homeowners do not have to worry about tripping hazards and have a beautiful level entrance to their home.

We have a small ally between our home and our neighbors. It is sinking in parts and cracked in others. Instead of tearing it all out I discovered Polylevel. Considering the close quarters it seems like a perfect solution. Please call between 9am and 5pm any day of the week.

Vicinity of Harbour Ridge Ln in Downingtown
A recent inspection was conducted for a home I would like to purchase and evidence of both a cracked foundation in the basement and moisture entering the area appear to be present. the inspector recomended contacting you for a quote/estimate for mitigation. The inspector indicated that it could be as simple as redirecting the spout away from the house however we would still need to seal the crack, or it could require excavation to the front of the house or sealing from the inside to direct water to the sump pump. Unfortunately the inspection period is over on the 20th so we will need a verbal estimate over the phone to include the price in our request - this was left off the inspection report. If repairs are to be done we would be using BQ. I can answer any questions you have about the crack or the moisture, and can include the inspection report as well as contact information for the inspector. Email or text message is best for initial contact as I do not use my voicemail. Thank you and look forward to speaking with you soon!

Vicinity of Karrens Way in Downingtown
I have a approx 25 yr old home with full basement, cinder block wall, and slab monolithic floor. It does not flood, but has been damp and moldy always. I keep a dehumidifier running constantly and 2 years ago paid an outfit to remediate the mold,(sprayed muriatic acid) and paint the cinder blocks. The slab floor has a 1 to 2 inch gap all the way around and after heavy rain, I can literally see water running into the channel between wall and slab. I need a permanent solution.
