Common Problems

Water in the Basement

90-95% of water issues are due to poor drainage or improper guttering
The obvious signs of water problems is water running down foundation walls
Cracks in basement floor slabs (heaving) is normally a sign of water under the floor slab and is caused by an expansion of clay soil under the floor slabs
Other signs of heaving would be cracking in sheetrock in upper levels usually resulting in doors not fitting properly

Efflorescence – water beneath floor / behind wall

Efflorescence is a white powdery substance that builds up by cracks or around the perimeter of the basement between the floors and walls
Proper drainage is to have a one inch drop in grade away from the foundation or six to ten feet away from the home which is not always possible
All concrete patios, sidewalks, or driveways should be sloped away from the home

Drain Tile and Sump Pumps

Sometimes the only way to take care of water in a basement is to install a perimeter drain tile system in problem area to lead to a sump pit with a sump pump. Water is then drained to the exterior of the home.

Negative Drainage of Concrete Surfaces

Mudjacking is a process of mixing soil with Portland cement and water and dydraulically pumping slurry underneath the surface to lift the slab back to its proper level
Another option is total replacement of a concrete surface which usually runs from two to three times the amount of Mud Jacking

Epoxy/Urethane Injection

Epoxy or urethane injection is a process of sealing cracks in poured concrete walls in which two-part epoxy is spread over the outside of a crack
We usually recommend urethane over epoxy because it sets up as it expands and also remains flexible and will hold a seal better
Hydraulic cement is another way of patching cracks
Tuck pointing is the only way to patch cracks on block and stone walls

Wall Deflection

All types of foundation walls are subject to deflection or inward movement. It is usually caused by hydrostatic pressure due to improper drainage
Vertical Wall Restraints are the most common way to repair these walls. Common spacing is four feet on block walls and six feet on concrete and stone walls.
Deadman Anchors are also used to restrain walls but most commonly where there is a walk out or exposed foundation wall opposite of the problem

Wall Replacement

Having to replace a wall is most common in cement block walls, less common in stone walls, and least common in concrete walls
Usually, concrete walls can be excavated and pushed back to a more plumb position
When block walls are replaced, we fill the hollow cells vertically every thirty inches with rebar and concrete. We also put reinforcement wire on every other course of the blocks

Settling

Settling is a problem in many houses in the area
Settling is caused by foundation footings being placed on unstable soil
The most common time to see signs of settling is during droughts. Cracks in sheetrock, stone or brick veneers, and fireplaces are common signs
The most effective way of taking care of settling issues is Piering
There are different ways or Piering but the most effective of all are hydraulically driven piers which are fused to solid structure or bedrock
Different types of piers that we offer are: Model 350 hydraulically driven piers, helical lift piers, helical porch pier, helical slab pier, and new construction piers
Many of the issues that have been discussed in this section can be avoided with proper maintenance of property. If signs are already showing it is normally too late to take preventative measures and problems should be addressed immediately.
