Our Services Include

Replacement or Repair of Foundations

Replacing or repairing a foundation is required if the foundation beneath a house has either shifted or expands and contracts too readily. This expansion and contraction is caused by changes in soil moisture content. Because foundations are designed to be soil-supported, any soil movement also causes the foundation to move.

This soil expansion and contraction normally extends to a depth of 8-12 feet below the soil surface. This first 8-12 feet of below the surface is called the "active zone".

Dug out and Foundation Slab Replacement

Slab replacement is required if the concrete slab beneath a house has either began to sink or crumble. In which case new concrete will be poured into the breach.

With foundation replacement, a foundation is the concrete border outlining a structure. A foundation requires replacement if it begins to sink in. When this happens new concrete is needed to fill and replace the old crumbling foundation.

Creative Drainage and Ventilation

Creative Drainage involves the installment of proper drainage systems around the home.

Most building codes and roofing manufacturers require proper ventilation for warranty purposes. The most effective ventilation is a balance between intake (eaves) and exhaust (roof) as the warm air in the attic rises and is released through the roof vents it pulls in cooler air from the eave vents which keeps the attic temperature cooler.

Proper ventilation can also help to prevent ice dam formation in winter months by keeping the inside attic temperature closer to the ambient temperature outside. Intake vents are normally installed in the eaves or soffit areas of the home to bring in cool air to the attic space.

House Lifts & Under Space Additions - Framing

While there are several reasons you may need to lift a house, the main reasons are usually to dig a foundation or fix a crumbling foundation. Some homes were built on a slab with just a crawlspace.

Now that people are looking to expand their living space, one option is to build a finished basement. For homes that do not have a basement, this means the house must be lifted in order to dig and pour the foundations walls.

Retaining Walls/Slabs/Leveling/Seismic/Erosion

Retaining Wall- A retaining wall is a structure designed and constructed to resist the lateral pressure of soil when there is a desired change in ground elevation that exceeds the angle of repose of the soil. The active pressure increases on the retaining wall proportionally from zero at the upper grade level to a maximum value at the lowest depth of the wall.

Leveling- Leveling involves flattening a surface so it is completely level. This act is required if a foundation begins to dip or warp, this can cause cracks or damage to a structure's foundation and concrete slab that is located just underneath a home

Seismic & Erosion- A foundation for a home is built strong for support. However natural occurrences such as erosion and seismic shifting (aka: earthquakes) can result in the damage of a house's foundation. We provide the service of repairing damage caused by these natural occurrences which involves replacing or repairing a house's foundation and concrete support slab.
