Does Your Basement Or Slab Foundation Need Repaired?

There are several different methods and solutions that must be waded through before making the proper call for your home and family. Foundation fix is outlined as : the art of underpinning or stabilizing a structure which 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 more stable than the current soil the is resting on. This is accomplished by providing extra support from this footing or wall thru piers or anchors. The people responsible for designing and creating these methods include foundation engineers and foundation repair contractors. A foundation engineer is responsible to evaluate the structure in question and then provide a proposal for his design.

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

This underpinning provides a way to lift the home to an acceptable level and forestall further settlement. Slab on grade or pier and beam foundations are the most susceptible to weak or expanding soils. or expanding soils. Thanks 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 houses are monolithically poured with the slab and beams cast together creating a firm foundation. This rigid foundation becomes at the mercy of differential settlement when moisture levels under the slab don’t remain consistent. This can spring from damaged water lines, poor drainage or maybe insufficient guttering.

Steel push piers and helical piers are usually an engineer’s suggested solution for these conditions. These piercing systems supply a deep foundation that may now be lifted off of to get back a satisfactory elevation. In extraordinary cases, disastrous failure can happen from these wall stresses.

When basement houses are originally designed it is with normal moisture content. Poor drainage often causes unjustified pressure to build behind basement walls exerting forces on the basement foundation. This is often 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 extra 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 complete excavation of the affected area. 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 extremely heavy loads due to their design and the fact of their installation force equates to their resisting force. Whatever the solution to your concrete cracks knowing the cause of your foundation problem is the first step to fixing your foundation. Hiring a professional engineer is always the 1st step to making your house structurally sound. Now go out and take a look at your foundation for a concrete crack or settlement.
