Concrete Lifting / Leveling

Does your driveway, sidewalk, walkway, concrete steps or patio have problem areas where sunken concrete has caused uneven surfaces and tripping hazards to form?
Sinking Concrete Repaired

Conditions where outdoor concrete has already begun to sink are not uncommon in Arizona and are often the result of shifting or a weak soil base or erosion.

Symptoms of Sunken / Sinking Concrete:
  • Sinking concrete steps or sidewalks
  • Cracked, bumpy and uneven driveways or patios
  • Cracking and sinking under concrete slabs
  • Washout of soils under concrete slabs
  • Repeated cracking of concrete slabs

Have you noticed horizontal cracks on the outside foundation stem wall of your building? If so, this could be a serious foundation problem.

Usually these horizontal cracks are a result of the rebar oxidizing.  Given enough time, the concrete will spall and eventually split as the rebar dissipates in entirety.

What Causes Stem Wall Cracking?

This is caused by chloride ion exchange in the moisture laden pores of the concrete that facilitates the oxidization of the rebar. Once started, it's very difficult to stop with traditional means. Sealing the crack with epoxy will not stop the rebar from continuing to oxidize and expand.

Cracks may start out small, but continue to grow like the picture above. These cracks are a result of the rebar oxidizing (rusting). This occurs because the pores of the concrete contain miniscule amounts of water that actually conduct electricity, forming a tiny current between the rebar and the outside of the concrete wall. This current facilitates a flow of chloride ions that cause the rebar to rust.

Eventually the rebar grows large enough to break the concrete out completely on its own, causing total failure. Don't ignore the warning signs! The good news is that we can fix these problems. We are your trusted experts for stem wall repair. 

 

Crack Stitching

By utilizing pre-cured carbon fiber stitching systems used to bridge shear forces, we can repair cracks in foundations and floor slabs. The systems are installed at a fraction of the cost of traditional steel dowels and with less heavy equipment and disruption to the homeowner. 

Arizona Foundation Solutions are certified applicators for HJ3 Composites and is the preferred applicator for Arizona. HJ3 is one of the world leading authorities on the use of these materials in the construction environment.

We cut stitches into your cracked foundation's concrete, drop carbon fiber laminates into the cuts and adhere with low viscosity polyurea. This system is stronger, faster and more cost-effective than the more traditional embedment of rebar dowels into the concrete. Crack Stitching is a reliable way to repair concrete & foundation cracks running along your floor.
