WHAT IS A STEEL PIER?
A 2 7/8" to 3 1/2" well casing is pressed into the ground to a resistance of 5000psi. The pier is then topped with a special bracket which attaches to the beam of the foundation. The structure is then lifted using this bracket.
The steel pier, also called a steel piling is consistently the deepest driven pier providing the most foundation support.
HOW LONG DO STEEL PIERS LAST?
Steel piers provide the very best in long lasting foundation support with minimal impact on vegetation.
HOW ARE THEY INSTALLED?
The strong, steel pier is driven to solid rock or a hard load bearing strata at depths of as much as 80 feet. There are tens of thousands of steel pier installations in the Dallas Fort Worth Metroplex.
The amount of repair time is dependent upon the depth to which the pier system must be driven.
WHAT IS A CONCRETE PIER?
For homes and light commercial buildingson slab foundations, concrete piers are columns that are formed by pouring liquid concrete into holes drilled into the ground.
HOW LONG DO CONCRETE PIERS LAST?
It is simple, concrete piers will last as long as your concrete foundation.
HOW ARE THEY INSTALLED?
In each location where a pier is going to be installed, a hole is drilled down to the target depth, generally between 12 and 20 feet below the surface of your slab. Each hole is typically 12 inches in diameter.
Next, a set of reinforcing steel bars are tied together and lowered into the hole.
The concrete is allowed to cure or harden for 7 days.
When all of the piers are hardened, hydraulic jacks are placed on the piers and are then used to lift your foundation.
Once your foundation is lifted, steel and concrete spacers are placed on the piers to support your foundation, and the hydraulic jacks are removed.
The final step is to cover the piers and clean up.
WHAT IS MUDJACKING?
Mudjacking means the process of lifting a building, driveway, or any object by pumping concrete (known as mud to people who work with it) underneath it.
Mudjacking is also performed by injecting polyurethane resins. When the resins mix underneath a foundation, they form a plastic that contains gas bubbles. As the gasses and plastic expand, they can lift buildings. Polyurethane injection is much more costly than lifting with concrete, but it is much more precise and controllable.
WHEN SHOULD MUDJACKING BE USED?
We use mudjacking as a convenient and inexpensive way to lift pool decks, patios, driveways and other items made of concrete that is 3 to 6 inches thick. Mudjacking is cheaper than pouring new concrete, and can often be completed in a day or two.
On foundations mudjacking is used when a foundation is so weak that piers or pilings can not be installed. Mudjacking should not be used under a foundation if there is a chance that the soils under the mud will expand. If soils under injected mud or concrete expand, the soils will push up on the overlying structure and move it upwards.
It has become all to clear and evident, that improper drainage often leads to the need for foundation repair and house leveling.
In North Central Texas, much of the problem is attributed to the rapid hydrating and dehydrating of clay soil.
When moisture collects under a concrete slab, especially here in the metroplex, the soil swells. This swelling or upheaval causes the slab to bend, shift and crack. As the slab bends, even before breaking, damage will occur to masonry, sheetrock and tile floors. Then as the soil begins to dry out, another round of shifting could occur causing damage.
Cracks in masonry, sheetrock and tile floors are visible signs of foundation problems and you should contact Triple Jay Foundation immediately for a free estimate to minimize further foundation damage and repair costs.
HOW DO I KNOW IF I HAVE DRAINAGE PROBLEMS?
Malfunctioning Gutters and / or downspouts that dump
Cracks in the foundation
The land should slope downward away from the foundation to assure that water does not collect near or under the slab, and also to prevent a soil robbing, streaming effect. The slope should be in the range of 1 inch per foot for the first 8 feet from the foundation.
There should be no pooling or accumulation of water either along the perimeter or within 20 feet of the foundation.
Plant borders may contribute to localized pockets of moisture accumulation. The borders act as a natural water reservoir, and occasionally sprinkler systems are run more often in the planted areas than in the grassy sections of the lawn.
Water from A/C units should be directed at least 3 feet away from the house.
HOW ARE SOME COMMON DRAINAGE PROBLEMS REPAIRED?
Practical solutions to fix drainage problems:
Repairs may include grading to alter the drainage slope, adding surface drains, or adding French drains.
Sometimes French drains and surface drains are confused.Surface drains remove water at the surface, while French drains collect and drain away sub surface water. Sub surface water is often the culprit as it causes soil in the first 3-5 feet of depth to expand, directly driving upward the beams which provide structural integrity to the house.
A French drain may include surface drains, but also includes a buried perforated pipe that collects sub-surface water. The drain is buried around three feet away from the slab, to a depth of at least the bottom of the perimeter foundation beam. Distance to the house should never be less than the excavation depth of the drainage system. Excess water either flows off through the drain pipe, or is accumulated in a reservoir and pumped away by an automatic sump.
