The sidewalk between this customers home and garage had become uneven over the years turning it into a trip hazard. The couple contacted NBS to "smooth" out their problem areas. We used PolyLEVEL injection to lift and level the sidewalk. After leveling, the joints were sealed with NexusPro Joint Sealant to avoid future water intrusion thus assuring a long lasting solution.
This is another example of a very common problem, settling concrete in front of the garage. With the driveway Northland Basement Systems fixed the sinking concrete with PolyLevel, bringing it back to its original position. Once the driveway was lifted and stabilized we used a SurfacePro concrete sealer to help protect the surface of the concrete. The joints or seams in the driveway were then sealed with NexusPro joint sealant to prevent water from getting under the concrete. The use of these three products together is called our "Concrete Protection System" and offers our customers the best long term outcome.
This customer was experiencing significant settlement in a corner of his garage. Our inspector recommended PolyLEVEL to stabilize and lift the affected area. Our technicians were able to stabilize and raise the floor to nearly it's original position. Our customer was pleased with the results.
Cracked concrete happens when part of a concrete slab breaks and sinks into underlying soil that has compressed or washed away. These cracks aren't just unsightly; they offer moisture a way to seep beneath the slab. This can cause the underlying soil to soften or even wash away completely. That in turn can cause the slab to crack further as it sinks into the void left by the washed-away soil.
To prevent moisture from seeping into the soil beneath, those cracks need to be sealed, as do the control joints that were cut between the slabs when they were first poured. While you could seal them with urethane caulk found at your local big-box DIY store, that is a solution that is prone to cracking, bubbling and drying out over time. Which means you'll likely be sealing them again... and sooner than you thought.
NexusPro is a silicone-based sealant for joints and cracks specially formulated to provide long-lasting flexibility and to stand up to harsh weather conditions. Unlike traditional polyurethane sealants, NexusPro resists UV rays, which means it won't crack, bubble or dry out. That means a single application can seal the joints and cracks in your concrete driveway, patio, pool deck or sidewalk for years to come, protecting it from damage caused by soil compaction and washout.
