Testimonial by Frank R. from Philadelphia, PA

Philadelphia, the City of Brotherly Love and the fifth-largest city in the U.S. is considered the birthplace of our great nation. Thomas Jefferson, John Adams, and Benjamin Franklin wrote the Declaration of Independence in Philly, and the Founding Fathers signed it here. Philadelphia is also the home of the Phillies, the Eagles, the 76ers, and the Flyers -- one of a handful of cities in the US that can boast teams from all four major sports leagues.

Philadelphia also sees its fair share of snow and rain throughout the year, and flooding is not out of the question, especially with a Spring thaw. There is always a risk of basements and crawl spaces flooding or leaking and that is where our basement waterproofing contractors can help.

Philadelphia's Best Basement Waterproofing Contractor & Crawl Space Repair Company

Not having a dry, waterpoof Philadelphia basement or crawl space can lead to mold growth, structural issues, rot, musty odors, and ruined belongings. Unfortunately, it also becomes a constant source of stress in your life. Fortunately, our waterproofing specialists are fully-trained with the backing of over 27 years of proven Basement Systems crawl space and basement waterproofing science.

Leaky basements can pretty much start from the day the house is built. Water can leak into your basement or crawl space through any kind of opening -- a foundation crack, the walls, floors, or joints between them, even solid concrete itself.

This is why the basement waterproofing products and systems in place from the Basement Systems Network is so critical to a healthy, dry basement or crawl space in your home. In order to have a fully waterpoofed home we install an internal drainage system that flows to an installed sump pump developed from years of proven testing. If their are any foundation cracks we can seal them. To avoid a wet basement going forward, we install an energy efficient basement dehumidifier to avoid moisture build-up. Contact us today for a FREE estimate for your crawl space or basement waterproofing needs.

PolyLevel™ Concrete Leveling & Lifting in Philadelphia

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

Our foundation repair 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 mudjacking (or slab jacking) instead of foam. Mudjacking is heavier, requires larger holes in the concrete, and does not last as long as PolyLevel. Call us today to learn more.

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

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

Job Stories From Philadelphia, PA
BQ Saves Plumbing Business from Collapsing

The owners of a Manayunk plumbing business in Philadelphia began experiencing issues with opening their windows and doors due to their cracked foundation. They noticed a large crack forming in the wall that connected their garage door to the building itself. The crack in the foundation was causing the building to sink, and needed immediate stabilization in order to save the building from completely collapsing. They reached out to us after seeing one of our "cracked foundation" yard signs and then scheduled a free estimate to determine how bad the problem actually was. 

After a representative visited the Manayunk business and performed an estimate, he was able to determine that the crack in the wall was causing the business to substantially sink, therefore making it difficult to open windows and doors. He proposed that the best solution for this problem was to insert a push pier system in the wall which would close the crack and stabilize the foundation back to where it originally once was. Four push piers were inserted into the wall, and in just a few days the foundation was stabilized. Since the push pier install, the owners of this Manayunk plumbing business have had fully functioning windows and doors, and the foundation has stopped sinking. Using our push pier system we were able to stabilize the foundation, and save a Manayunk plumbing business from collapsing.

We are considering refinishing our basement and know that there was a flood once in the past before gutters were re-routed. Currently I think some places might be having condensation issues, also have a radon system and wonder if that changes sump pump options.... Bottom line, would like to see what waterproofing would need to be done and get a quote for it before starting any renovations.
