Foundation repair is complex and should only be handled by a company with the right experience, equipment, and knowledge. It’s a job left to the professionals, and if you see signs of concern, it’s essential to act immediately. Contact Sugar Land Foundation Repair Solutions for professional expertise.
The first step is determining what type of repair is needed. Many factors can influence this.
Piering or piling is a method of foundation repair that involves the transfer of the weight of the structure from the weaker, expansive clay soil to a deeper layer of rock and stable soil. This technique is a much more permanent solution than slab jacking and can help prevent future damage to your home or building.
The first step in determining if this method is appropriate for your foundation is to have a geotechnical engineer compile a detailed report on the soil conditions under the structure, its load-bearing capacity, and other important information. Once the report is complete, a foundation contractor can then discuss repair options with you.
This method is often recommended for homes that are built on a pier and beam foundation, as opposed to the more common slab foundation found in newer construction. Pier and beam homes are often raised off of the ground with a crawl space underneath them, which can make accessing the structural support system much easier than in a slab foundation home.
Once the piering process begins, the foundation repair team will install temporary brackets along the foundation. They will then drill holes down to the weight-bearing soils and fill them with concrete. These new piers will then be attached to the existing foundation, which will help to prevent further shifting and provide stability for your home.
Piling can also be used for commercial or industrial buildings that are located in areas with particularly challenging soil conditions. These types of buildings require a large amount of stability for their continued use and safety, so it is essential to ensure that the soil under the structure is in good condition.
Helical piles and piers are often utilized in these types of applications because they offer exceptional durability and strength. They can be pushed into the ground using hydraulic pressure, which can save time and money during installation.
Basically, these foundation support systems are large steel cylinders that have been pre-cast or pre-stressed. The cylinders are drilled into the ground and then pressed into place with hydraulic rams. The foundation repair team will continue pressing the piers into the ground until they reach what is called “the point of refusal,” which means that the soil can no longer support the piles.
Soil modification or stabilization
Soil stabilization is an engineered process where a contractor blends in additives to improve the engineering properties of soil. These additives can be dry (cement, lime, fly ash) or wet (asphalt, emulsion, BASE ONE, calcium chloride). The goal of this process is to reduce the shrinking and swelling characteristics of wet and expansive clay soils as well as improving the load-bearing capacity of granular or dense sub-grade intended to support pavement sections, building pads and runways.
This is a highly effective method of soil improvement that allows a construction team to build on site in marginal soil conditions without the need for costly remove and replace. Many job sites where foundations, roads or airport pavement are being built have naturally wet and elastic clay soils that can be treated with soil stabilization to add strength and engineering properties to the soil.
One of the most common ways to repair a cracked and shifting foundation is through slab jacking. A concrete contractor will drill holes around the displaced section of your foundation, then pump a liquid material underneath your home to lift it back into place. This method is less expensive than other repairs and can usually be completed in a few hours.
If you notice a stair-step crack pattern in your home’s foundation, it’s essential to contact a professional right away. A contractor will scrub the crack with a wire brush and vacuum up debris to make sure that the area is clean and free of any other underlying issues. A syringe or caulk gun can then be used to inject epoxy or polyurethane into the crack until it is completely filled. This will seal the crack and help to prevent further damage, but a full evaluation by a professional is recommended.
The most important thing to remember is that even small signs of foundation problems should be evaluated by a professional. The longer you wait to address concerns, the more likely it is that serious structural problems will develop within the bedrock that supports your foundation. It’s also worth noting that many foundation repair methods are invasive and require heavy equipment. Unless you have a great deal of experience in the field, this is a job best left to the professionals.
When foundation construction or repair involves a difficult soil condition, piles are a common technique. These large, steel-cored concrete cylinders are driven into the ground using a heavy machine and can be very versatile in their ability to carry different types of working loads. They are also useful for supporting structures that extend above water or ground level. They are also often used for foundations that need to be able to withstand both bending and compression stresses. They are commonly found in marine foundation construction, multi-story foundations and retaining walls.
There are a few different types of piles that can be used for foundation construction and repair, including pressed concrete piers, helical piles and bell bottom piles. While the installation process may vary, all of these pilings provide excellent support for a sinking foundation and offer more stability than slab jacking. They can also be a long-term solution that does not require extensive excavation of the surrounding soil.
If you want to know more about how pilings can help in your home’s foundation repair, your experienced crew or contractor should be able to explain the advantages of each type of pile. In general, concrete piles are the most popular and can be installed quickly. They can also be more affordable than other types of piles. However, they do not offer as much flexibility as other types of piles.
To install a concrete pile, a hole is dug near the damaged foundation in your Central Texas home. Then, a concrete cylinder is lowered into the hole and a powerful hydraulic ram is used to drive it into the ground. The cylinders are prefabricated, so there is no need to wait for the concrete to cure on site.
This method of foundation repair is a bit more time consuming than other methods but can be very effective in tough soil conditions. In addition, the concrete piles will not rust or be affected by corrosion. This makes them a great option for areas with high salt content. Another benefit of this method is that it requires less demolition of existing structure.
Poured concrete piers
Poured concrete piers, also known as pilings, are another option for foundation repair. They’re a lower-cost alternative to steel piers, but the soil conditions under your house will determine whether this is an adequate remedy. Concrete piles are blocks or cylinders of pre-cured concrete that’re driven or placed below your foundation into compacted soil. They may be a few inches long and wide or many feet long and thick. The length and thickness of the piles will depend on the type of soil under your home, the weight of your structure and how much support the soil needs.
To install poured concrete piers, your contractor will dig holes beneath your foundation. They may use an auger, which resembles a large corkscrew, or a backhoe to drill these shafts. They’ll also add a rebar or steel cage inside the hole to give the pier strength. Then they’ll fill the hole with liquid concrete and allow it to cure. Once the pier is ready, your foundation contractor will attach it to your foundation.
A good quality drilled concrete pier can be a sound solution for foundation repair, but you’ll want to consider your options carefully before hiring a contractor. There are some bad apples in the construction business, and some will take shortcuts that can end up costing you big.
One of the most common shortcuts is not drilling the shafts deep enough. The shafts should be driven to the point where they’re at or above the “frost line” — the depth where the soil no longer freezes in winter.
