There are multiple different techniques and solutions that must be waded through before making the correct decision for your house and family. Foundation repair is defined as: the art of underpinning or stabilizing a structure that has moved from its originally created design.

To underpin a home or structure one must extend the current foundation into a soil strata or layer that is deeper and steadier than the current soil the is resting upon. This is accomplished by providing additional support from this footing or wall via piers or anchors. The people in charge of designing and instituting these with and foundation fix contractors. A foundation engineer is responsible to size up the structure in question and then provide a proposal for his design.

With appropriate building sites becoming rarer many home builders have been building homes on less than ideal lots. These subpar lots have less than appropriate soil conditions to support many structures.

This underpinning provides a method to lift the home to an OK level and prevent additional settlement. Slab on grade or pier and beam foundations are the most susceptible to weak or expanding soils. Due to the nature of having an enormous surface area resting on the uppermost soil layers these foundations have a propensity to move as the soil moves. Most slab on grade homes are monolithically poured with the slab and beams cast together making a stiff foundation. This rigid foundation becomes susceptible to differential settlement when moisture levels under the slab don’t remain consistent. This can come from broken water lines, poor drainage or maybe insufficient guttering.

Steel push piers and helical piers are often an engineer’s suggested solution for these conditions. These piercing systems supply a deep foundation that will now be lifted off of to regain an adequate elevation. In extreme cases, catastrophic failure can occur from these wall stresses.

When basement homes are initially designed it is with normal moisture content. Poor drainage often causes undue pressure to build behind basement walls exerting forces on the basement foundation. This is regularly the source of concrete cracking and water to infiltrate the space. There are two common fixes to bowing basement walls. These wall anchors are embedded into competent soils beyond a section of influence surrounding the structure. With this system total excavation isn’t needed and because of this additional soil load, wall recovery is accomplished over time with continued tightening of the anchor rods.

Next, there are helical tiebacks. This system of basement or retaining wall anchoring involves the entire excavation of the areas affected. Helical anchors are screwed into the soil hydraulically, and then attached with a wall plate situated within the basement wall. With the full excavation the wall can be instantly pulled back to plumb. The helical anchor can resist extraordinarily heavy loads due to their design and the fact of their installation force equates to their resisting force. Whatever the answer to your concrete cracks knowing the reason behind your foundation problem is step 1 to fixing your foundation. Hiring a professional engineer is always the first step to making your home structurally sound. Now go out and take a look at your foundation for a concrete crack or settlement.
