A Baker's Waterproofing Case Study

A home built in 1952 only started to experience sinking concrete around 2016. However, in the following two years, the problem quickly got worse. The Bethel Park homeowner was now concerned about her guests tripping on these uneven slabs.

She heard about Baker’s Waterproofing from her sister’s friend who works at Nicolella Roofing in Washington. So she set up a free concrete inspection.

Our certified specialist, Mike Felt, inspected the inside and outside of the home. Mike identified a cracked foundation, but the homeowner wanted to wait to complete that repair work.

One potential issue was the large tree nearby. Tree roots can cause damage to concrete as well as pose as an obstacle while attempting to fill in empty voids beneath concrete.


Mike recommended our PolyRenewalâ„¢ injection foam, and Caulk Joints joint sealant. Our crew installed these concrete solutions on three separate dates, each project lasting less than a day.

Our crew performed a deep cleaning to open the concrete’s pores. Then, we sprayed SealantPro to let it bond to the concrete for long-lasting protection against water and harmful chemicals.

Another day, we injected our high-density and lightweight polyurethane foam into the empty space beneath the sinking concrete. This foam expanded to lift and level each concrete slab.

Once the concrete was sealed and stabilized, we filled the joints between the slabs with our silicone-based sealant. This joint and crack sealant was specially engineered to provide long-lasting flexibility and to stand up to harsh weather conditions.

The homeowner mentioned that she wanted a safe entryway for her guests. She also told us that chipmunks ran through the voids below the concrete. Now, our injection foam reversed those issues for good! Plus, the appearance of the concrete around her home has greatly improved!
