Stem Wall Cracks

 The steel interior reinforcement bar expands up to five times its size in diameter, from 1/2 inch #4 bar to 2.5 inches, breaking out the weakest side of stem wall foundations. Once this electrical current, or drive, takes hold, it will continue left and right unless repaired immediately. The crack is allowing more moisture and oxygen to the interior reinforcement steel. Chloride ion exchange in pores of concrete low voltage electrical current oxidizes the rebar. Most stem wall repair contractors here in Arizona do not remove the reinforcement steel that’s causing the stem wall foundation crack problem. The cracked wall is chipped out to expose the reinforcement steel rebar within, without excavating the dirt down to the  top of the bottom support footing. Why? “because there are no intentions of waterproofing or painting the patch work once completed. And cost less in labor costs”. “All stem wall repair should be waterproofed”. It is most likely, and is recommended worldwide, that steel needs to be sandblasted, and the rust removed from the steel reinforcement bar. However, sandblasting does not remove the hard to get to far side of this contaminated (rust) oxidized rebar. This is why it is recommended that the reinforcement steel be completely cut out and removed entirely, and replaced. Any rust left behind may cause more cracking of the foundation wall that was repaired.

Delay In Your Stem Wall Crack Repair Can Lead To Structural Issues.

Sika Solvent-base, is a rust inhibitor patch material and is widely used throughout the United States. This rust inhibitor deters the oxidation process, but does not solve the issue of the rust that could not be removed. This material has to have cure time before any acrylic waterproofing or paint, could be installed on it, or it will just (alligate) or peel off. This time frame can run from 7 to 21 days curing time. This is why most all other stem wall repair companies do not waterproof or paint their repairs, or they recommended that you Don’t paint, just to get out of it. Not to mention excavate the dirt next to the foundation. If only all foundations were waterproofed prior to dirt being replace back next to the perimeter of these foundations, This type of foundation problem may not exist. It is becoming more apparent over time, that the experience of these results are quite clear to those who are in the concrete stem wall foundation repair industry. Home builders, architectural and engineering firms, have yet to get caught up to speed why these horizontal cracks in stem wall foundations are acutely present and becoming more numerous over time. Concrete Repairman® does recommend removal of oxidized rebar, or reinforcement steel, and replaced with new steel, encapsulated with two-part rust inhibitor epoxy coated steel, and not fiberglass products. The recommended replacement is, that if the steel has scaled more than 20%, the rebar should be removed and replaced. This new replacement steel, encapsulated with rust inhibitor epoxy, should be installed after surface a vertical stem wall foundation has been thoroughly cleaned, and any chipping cracking and flaking of the concrete stem wall be removed. A high-performance structural grout, specifically hydraulic grout, is used to build back these concrete vertical stem wall foundations. High grade polymers are used as a primer coat prior to any patch material being applied. These polymers, or primer coats, should be tacky or dry to the touch prior to patch bedding for the reinforcement steel is installed. This allows the new reinforcement steel to be embedded securely at the proper position, and location. The following concrete stem wall repair method is installing hydraulic structural grout patch in lifts. The reason why lifts are required is because of slump issues. Adding too much patch, and or too wet of patch, will fall off, or slump away creating air pockets. Slump of any concrete cementitious material, including patch materials, should be at its lowest levels possible. (ASTM C143 – ACI slump test video). Meaning that, the overuse of water will only decrease the strength of any patch, or concrete, and be at a higher slump. 4″ to 4.5″ slump is recommended. The over abundance of water in the mix, also reduces durability, (watch this video of “Foundation Repair Problems caused by Over Use of Water in Patch Mix with NO Primer Coat” improper use of patch material), however will increase the workability. *The overabundance of water used in mix designs, and trapping moisture at the surface vertical or horizontal slabs, will create spider cracks to occur, including patchwork. This especially happens when the steel blade of a Fresno traps the moisture or ( bleed water) that comes to the top of the slab prematurely. The use of a Fresno steel blade in the finishing process should be done when the bleed water subsides. Your slabs or patchwork will not have spider cracks if proper finishing techniques are used.* After embedment of new reinforcement steel encapsulated with rust inhibitor epoxy, another lift is added to cover. Continuing with lifts out to a plumb vertical face that matches the existing concrete stem wall’s vertical wall top and bottom. Prior to the outside patch becoming dry and hard, a trowel is used to smooth, and finish the vertical surface. Once the patch has time to cure out usually within just a few hours, or even minutes, (depending on humidity, and temperature), and has turned to a dull shade, waterproofing can be applied. No need to wait 14 to 28 days for curing. Once the waterproofing of the stem wall has dried, exterior house paint then can be applied just below the dirt grade elevation. Foundation Repair Phoenix.

Instead of using a waterproof coating, opt for a rust-free system. The resulting rebar won’t stain the stem wall, and won’t leach into the environment. Using the right material can prevent future problems.

Regardless of the type, you can expect to pay between $4,000 and $12,000 for the repair. More about foundation repair

When evaluating the costs for foundation repair, keep in mind that the cost will vary depending on how much of the foundation is to be lifted. For example, if a crack is over an eighth of an inch, you’ll likely have to hire a structural engineer. However, if the cracks are wider than one-eighth of an inch, they’ll require a structural engineer. For more extensive foundation repairs, you’ll need to consider slabjacking, which involves pumping a concrete mix under the foundation. This can cost up to $500, while a concrete block foundation can require up to $13,000 for the work.
