Piering is a process used to reverse or stabilize foundation settlement.
The piering process uses steel tubes that utilize the weight of the structure to drive the piers to bedrock or other load bearing strata. The piers are spaced about 7 feet apart and are used to level or stabilize an existing foundation. Once the tubes are driven, the load of the structure is fully transferred to the pier through an underpinning bracket that is positioned underneath the footing. The structure is then stabilized and will prevent any future settlement. They can also be used to lift the structure back to as close to the original position as possible.
Wall restaints are an essential element in the stability of walls.
When a wall is bowed less than 2 inches it is recommended that the wall be restrained from further inward movement with steel wall restraints. When hydrostatic pressure from the soil is putting pressure on the foundation walls and causing them to lean or bow inward, it is necessary to supply an equal resistance on the opposite side of the wall to ensure the wall will not continue to shift, crack, and bow. Steel beams are installed vertically against the wall and anchored to the floor joists above and to the concrete floor below.
Poor grading and drainage can damage foundation walls to the point they need to be rebuilt.
As foundation repair specialists we have access to the most innovative products in our industry such as hydraulic equipment and helical wall anchors that can straighten and stabilize foundation walls that have bowed, tilted and cracked. When the foundation damage is so extensive that stabilization techniques are not cost effective we recommend that the walls be rebuilt to avoid extensive and ongoing repairs. After clearing the basement we will build a strong temporary framework to support the beams and floor joists that rest on the wall that's going to be replaced. Replacement foundation walls are typically constructed from concrete block, stone or poured concrete. A new poured-concrete footing provides a solid base for the block wall if the old one is defective. Once the new wall is complete, the temporary supports can be dismantled.
Years of neglect on a foundation can lead to leaning or bowed walls.
Through the years we have researched all the systems and methods used for straightening foundation walls. In order to straighten a wall the soil is excavated down to the footing. Once the pressure has been removed, hydraulic lifting equipment is set in place to restrain the wall while lifting the framing above off of the foundation. The hydraulics are then used to straighten the wall. Permanent restraints are then set into place to prevent future inward movement.
Crack injection is an easy and fast way to repair foundation cracks.
Leaks in concrete structures have been a problem for homeowners since concrete was first used. For this issue we use a special polyurethane resin that is injected into the concrete crack or hole under high pressure, expanding to fill the void. Polyurethane injection can be done from the inside without digging. This method provides a waterproof seal through the entire width of the concrete. Not just a surface patch. Polyurethane is water activated, so injecting it into a crack achieves an excellent bond to wet surfaces. It has the advantage of penetrating into very small cracks, no shrinkage and has elastic strength to tolerate the expansion and contraction of concrete.
Sump pumps help keep your basement, garage or crawlspace dry and clean.
If you have a flooded basement or one that is susceptible to flooding, then you know that it may be quite costly to repair the damage. When your neighborhood gets hit with downpour, the water trickles down into the lowest areas of your property, and can find its way to your basement if there are any tiny leaks or cracks in your foundation. A basement with water damage can be breeding ground for bacteria and mold to grow. The damp environment and unpredictable temperatures are some of the main contributors.
Interior and exterior drainage systems are recommended in basements that have water coming in around the perimeter.
To install interior drains, a trench is dug out along the wall. A perforated pipe and stone bed or footing drain are installed in this trench to lead the water away. The floor is then concreted over again. This method leaves a gap between the floor and wall that allows water from the wall to flow down into the drain. The water could be from a poorly installed window well, a crack in the wall or raising water tables. It is recommended to have your downspouts buried and extended away from your foundation so that water is diverted to a different location.
Center supports can sometimes sag and sink over time due to unstable or poorly compacted soil.
Sagging, sloping, and out-of-level floors are common in old houses and can be easily repaired most of the time. With our hydraulic systems we can lift the framing back up and stabilize it to prevent future settlement.
Earth anchors are devices to permanently stabilize and secure basement and retaining walls.
These earth anchors provide an opportunity to straighten your basement wall over time. Minimal soil disturbance is necessary for the installation of these anchors which make them a very popular choice for homeowners . The anchor works on any type of basement or retaining wall. The installation can be done very quickly. The wall plates must be positioned correctly to supply support for the effected areas. The earth anchor must be placed in a solid soil mass or concrete ditch beyond any previous excavations. Over time the anchors can be tightened down in order to re align the wall.
