Oxidized Steel Rebar Repair Cost

Next up, oxidized rebar expansion. This type of horizontal expansion of the reinforcement steel breaks out the side of the stem wall and post tension foundation types also. The main difference between the two is, stem wall Foundation types go deeper into the ground. post tension Foundation types are usually only 12in to 14in tall and allow moisture to go in underneath the slab oxidizing the reinforcement Steel. This oxidation of the reinforcement steel is breaking out the sides of load-bearing walls around the perimeter of these homes. Stem wall Foundation types because they are deeper, do not allow moisture to go underneath them and is unlikely to occur. However, because the paint is only painted down to the top of the dirt grade. The moisture goes directly into the vertical wall, oxidizing the reinforcement steel. There is no protection from this moisture and oxygen getting to the reinforcement steel causing oxidation process. This oxidation process causes a low voltage electrical current to charge the interior reinforcement Steel. Thus causing the expansion in horizontal crack that is very typical in prominent arid climates of Arizona. This type of foundation repair, done correctly, remove the affected cancerous rebar that exists, and replace with same diameter reinforcement bar coated with rust inhibitor epoxy. Most professionals will agree, to sandblast Bastille clean. the problem with this repair method is, you cannot remove the rust on the far side of the steel without removing it. if not removed this cancer is expansion oxidation of the reinforcement steel will continue and come back later in time.

Post Tension Foundation Repair Cost

Post tension foundation repair cost can be from $500 to $50,000+ depending on the type of damage. Most of which we see here in the desert climate of Arizona region, is oxidation of the reinforcement Steel. Because of the fact that these Foundation slabs are considered floating slabs. Meaning they float on top of the ground because of the expansive soil problems that were discovered. this type of post tension Foundation is very susceptible to oxidation of the re-enforcement hairpins on the interior walls around the perimeter footing. This perimeter footing wall is not only shallow but allows moisture to readily infiltrate underneath the steel. Water vapor transmission then wants to reach equilibrium evaporating upwards with the oxygen. This process starts the oxidation process. The half moon wedges, that hold the cable tension to 27000 psi. these Legends are also made of steel and corrode, releasing the tension on the cable or cables. This causes subsidence, or sudden settlement, and other detrimental damage, including structural problems. I don’t agree with post-tension slab construction, because of the effect that it allows moisture directly underneath, causing these types of damage to happen. To correctly repair this type of damage, once the cables have been released. the cable is then removed pushed through buy the new cable. The new cable is then tightened after the interior reinforcement hairpin has been removed and replaced. The structural patch secures the bracket and hairpin . After proper curing of this patch material, tension can be reapplied to the cables. This type of damage, meaning the release of the cables, is sudden, and may be covered underneath homeowners insurance coverage and policies. Please refer to your home insurance policy.

Beans homes foundations are constructed monolithically because they are much stronger and hold up to the elements better than any other type of foundation structure. the footprint signature of the bottom of these foundations are usually 16 in width and 16 in wide by 24 in tall. Sustainability of these types of Foundations monolithic, I also reinforced with steel throughout. not only in the perimeter footing running continuously, but also have returned bars into the interior floor slap approximately 4 foot spacing. Because of the footprint is so wide settlement of these homes becomes less likely over the years. because of the Holmes age the roads are built up around them over the years, the grass gets mowed and cut, the wind blows more dirt, and over time the elevation around these homes become negative. now the holding of the moisture from the rain water coming off of the roof and Landscaping hold near these homes in this type of situation. bombs have been used to remediate this moisture from affecting the foundation stability from subside ins, and settlement issues. Subsidence issues will cause interior floor crack heave foundation heave, doors not to close correctly, cracks in the ceiling, drywall, and window cracking. interior floors can be ground down structurally crack stitching and a floor leveling underlayment can be installed to level uneven floors.
