Methods of Repair
Discussion of ways foundation repair contractors do their thing…underpinning with steel, helical, drilled or push piers.
The three basic methods of underpinning a residential foundation, be it concrete slab or pier and beam, all have their critics. Remember, underpinning is the process of getting piers (or pilings) under the foundation to shore it up. The type of pier impacts the cost of foundation repair.
When you are researching foundation repair cost per pier you’ll find quite a difference in price depending on the type of pier the contractor or engineer recommends. The mix also includes the Millennium Composite Piling System (TM)
Earlier this year one of my neighbors (Roy) had foundation repair done on his concrete slab. The hot dry summer drought had done its damage and resulted in some of the classic signs of foundation movement.
You could see separation of the brick veneer away from the window frames in the front of the house and by the garage door. There was a big diagonal crack (half inch or so) in one of the sheet rock walls in a small office inside the garage area. Similar cracks had developed inside the house proper.
With the cost of foundation repair in mind, Roy called three foundation repair companies for bids.
The foundation companies all suggested piers for the front and both sides of the house.The company Roy picked uses pushed concrete piers, a very common foundation repair method in Texas.
You know a drought is taking its toll on the slab foundation in your area when the local television news is running stories on how busy foundation repair companies are.
While some parts of the U.S. are finally drying out after record flooding this spring, other parts of the country including Texas are experiencing record dry conditions.
As I write this, my soaker hoses are running. You know the drill, when in drought, water foundation.
A TV outlet in Austin, Texas has a news article where they are talking to both homeowners and foundation contractors and things are not good. Well, not for the homeowners.
One of the homeowners has a problem with his doors sticking, not latching properly, and now cracks are appearing in the walls. Those are classic signs of foundation issues. (more…)
The three most common ways of underpinning a home foundation in need of repair are steel piers, pre-cast concrete cylinders (or push piers) and the drilled bell bottom piers. Each method has it’s pros and cons and affects the cost of foundation repair.
Steel piers can be shoved into the ground deeper than concrete cylinders because they have a smaller diameter. Using concrete cylinders provides more surface area for the “skin friction” concept of engineering. The drilled bell bottom piers is the oldest method of foundation repair and still widely used although this method takes the most time.
I’m watching TV the other day and here comes a commercial for the Olshan foundation company pitching a combination of steel and concrete cylinders for a foundation fix.
Here’s the claim: (more…)
Foundation contractors sometimes offer up to three methods of underpinning a house foundation. These three main methods of repair include pushed concrete piers, steel piers and the drilled or bell bottom pier.
I’ve run across one company that says the bell bottom pier is the best way to go. It is the oldest method, most tested and most reliable form of underpinning a house with foundation problems. It is the type of pier used in highway and major commercial construction and has been for years. The company is Dawson Foundation Repair and has locations across Texas.
A Slab Foundation on Heavy Clay Soil is Subject to Movement
During the rainy season, clay soils expand with the added moisture. When the soils dry out the clay soils shrink. This can cause not only up and down movement of your foundation but also lateral movement. And this can cause the classic signs of foundation problems…diagonal cracks in the walls, inside and out, doors and windows that don’t work right and uneven floors. (more…)
