"We shopped and spoke with many "facade restoration experts" before choosing to work with High Tech and we are so glad we did our research. Shaiful was by far the most knowledgeable contractor we spoke with and made us feel confident that he was capable of solving our issues.  When it was clear that there was no saving our original cornice, he offered up more than one suitable way forward. We decide to let his crew re-create the original piece from stone. The work they did left us with a beautiful and artistic facade the functions well in collecting rain water from the roof. The crew was respectful, clean and on time. They went above and beyond all of our expectations in touching up every minor detail so that the whole front of the house was left looking brand new. We could not be happier. Our home looks better than we could have imagined. I recommend High Tech Construction with no hesitation.

Concrete Leveling questions, answered by experts

Pros often use mudjacking or polyurethane foam injection to level a sunken concrete patio. Both methods lift the slab by filling voids beneath it. After properly compacting the soil beneath it to prevent future settling, the concrete may need to be removed and re-poured for severe sinking.

There is no real alternative to underpinning, although mudjacking and polyjacking are other repair methods that can add support from underneath your foundation. Rather than placing supportive piers under your structure, these involve pumping a material under your slab to lift a sunken section back into its original position. Polyjacking, in particular, is sometimes a suitable solution for stabilization issues under slab foundations, but underpinning is often accepted as the best and most permanent solution.

The polyurethane used for polyjacking will expand and cure in 15 to 30 minutes. After that point, your slab will be safe to walk on and even drive on in the case of a sidewalk or concrete driveway. Double-check with your concrete lifting specialist to confirm a curing timeline, as products can differ.

Polyjacking can be a permanent solution to sunken concrete if you also address the underlying issue—like poor drainage—at the same time. The polyurethane material itself can last as long as or even outlast the concrete you’re lifting it with. Your sunken concrete issue will likely return if you don’t couple polyjacking with proper drainage to prevent future soil movement and sinking.

A slurry of cement, sand, and water is injected beneath the concrete to lift and stabilize it.
