Signs of a settling foundation can be very subtle at first -- many homeowners can go months or even years before noticing a crack in their foundation. The long-term damage from foundation settlement, however, is ongoing and will lead to more severe foundation problems.
The signs of settling and sinking foundation are:● Stair-step cracks in brick or concrete block foundation walls● Cracks around doors and windows● Cracks in a concrete slab floor● Jamming, sticking doors and windows● Cracks in drywall
There are usually a number of different soil layers underneath a house.
Foundation settlement and house movement can occur when one of these soil layers can't support the weight of the home.
When foundation settlement causes your house to become unlevel, we can help
We recommend stabilize, repair, and restoring a foundation that's been damaged by issues related to foundation settlement and poor supporting soils by utilizing or patent-pending process. We utilize polyurethane foam to lift and level your foundation and your home. Polyurethane foam has been proven to be effective in raising concrete and filling voids. We have taken it further perfecting the process of raising your home from the inside by lifting the supporting structure and filling it with polyurethane foam. This specialized foam sets creating a solid base from which the foundation supported. The foam, once hardened, is as strong as concrete with less on the weight on the existing soil. It is also pervious to water, which was likely a contributing factor to your home sinking.
Total Foundation Replacement
To completely replace your home's foundation, the soil will have to be removed from around your home and your home will be jacked up and placed on temporary supports. Next, your foundation walls are completely removed, and a new set of walls are constructed. This is expensive, time-consuming, and extremely disruptive for a family. Even worse, it doesn't even address the real problem -- the soils around your foundation.
Many homeowners remove and replace their foundation without addressing the problem that caused the foundation issue in the first place. When this happens, they often find that after several years, they're facing the same problem all over again.
We address the problem using polyurethane foam. The foam expands to fill voids that contribute to the sinking and settling our your home.
To install concrete underpinning, the soils must be excavated from around the foundation. Larger concrete footings are poured beneath the existing footings. Once the concrete has cured, the soil is backfilled. When it comes to foundation footings, "bigger" is not necessarily "better." Most of the time, the underpinning will not extend beyond the problem soils under your home. If this is true, the larger footings you just paid for will continue to move and cause damage.
Concrete shrinks as it cures and small gaps can form between the new and old footings. Open gaps beneath a home are never a good thing!
When concrete underpinning is installed and fails to solve the problem, it is much more expensive to repair. Before installing a new foundation system, all that added concrete will need to be removed.
To install concrete piers under a home, the soil will first need to be excavated from around your foundation. Short, 6"-8" wide concrete cylinders are then pushed into the soil on top of one another, strung together by a wire. Shims are then placed between the top of the concrete pier and the footing, then the soil is backfilled. The over-lifting process required to perform shimming may lead to further damage to your foundation.
Blunt, wide concrete cylinders are difficult to push deep into the ground, making it very difficult to extend them past the poor supporting soils under your home.
Concrete can crack and break when under pressure, and even in response to temperature changes, making concrete piers a flimsy repair method.
Additionally, there is nothing to guide the direction for the pier, which means they might not be installed straight. So how will they support your home?
Because of these and other reasons, very few companies will recommend this kind of approach.
