CONCRETE SLAB REPAIR COSTS

Polyurethane concrete lifting is a cost-effective alternative to replacing concrete.

Concrete raising can usually be done for less than half the cost of pouring new concrete.

However, the savings may be even greater, since when concrete raising the costs of demolition, removal, and landscaping are eliminated.

Polyurethane concrete lifting raising achieves the same results as traditional mud jacking, but with a lightweight material that requires smaller and fewer injection holes and generally a longer lasting result. Also known as foam lifting/poly lifting/foam jacking, polyurethane concrete raising is the latest and greatest concrete repair method available.

FOAM JACKING BENEFITS

Over time, concrete slabs like patios, sidewalks, and driveways, can settle unevenly causing the slab to dip or slant. Aside from being an eye-sore, uneven slabs can be tripping hazards, make it difficult to shovel or blow snow, or even cause water to puddle leading to seeping or ice jams.

Can you replace a slab foundation?

Yes, it is possible to replace a slab foundation, but it is a complex and costly process that requires professional expertise.

Replacing a slab foundation involves removing the existing concrete slab and installing a new one. This may be necessary if the existing foundation has become damaged beyond repair or if it is no longer able to support the weight of the structure above it.

The process of replacing a slab foundation typically involves the following steps:

Excavation: The area around the foundation is excavated to expose the existing slab and provide access for the replacement.
Removal: The existing slab is broken up and removed, along with any damaged or unstable soil.
Preparation: The area is graded and compacted to ensure a level and stable base for the new foundation.
Reinforcement: Reinforcing materials, such as rebar or wire mesh, are installed to strengthen the foundation and prevent cracking.
Pouring: A new concrete slab is poured and allowed to cure, typically over the course of several days.
Finishing: The new slab is finished to ensure a smooth and level surface.

Replacing a slab foundation is a complex process that should only be done by experienced professionals. It can be costly, depending on the size and complexity of the foundation, but it is often the best solution for structures that require a stable and durable foundation.

What type of foundation repair is best?

The best type of concrete foundation repair will depend on the specific type and extent of the damage to the foundation. Some of the most common types of concrete foundation repair include:

Crack repair: If the foundation has cracks that are not severe, they can often be repaired using epoxy or polyurethane injection. These materials can fill the cracks and prevent further damage.
Slabjacking: This involves injecting a mixture of cement and other materials beneath the foundation to lift it back into place if it has settled or sunk. This method can be effective for small areas of settlement.
Carbon fiber reinforcement: Carbon fiber straps or sheets can be used to reinforce and strengthen foundation walls that have cracked or shifted.
Piering: This involves installing steel piers beneath the foundation to provide support and lift it back into place. This method is effective for severe settling or shifting of the foundation.

The best type of concrete foundation repair will depend on the specific circumstances of the foundation damage. It's important to consult with a professional foundation repair contractor to determine the most appropriate repair method for your situation. A qualified professional can assess the extent of the damage and recommend the most effective and long-lasting repair method.

What kind of cement to use for foundation repair?

The type of cement used for foundation repair will depend on the specific type and extent of the damage to the foundation.

For minor cracks and small repairs, hydraulic cement or epoxy can be used. Hydraulic cement sets quickly and is ideal for filling cracks and small holes, while epoxy is a strong and durable adhesive that can be used to bond concrete surfaces and fill larger gaps.

For more significant foundation repairs, a cementitious grout mix may be used. This is a blend of Portland cement, sand, and other additives that can be used to fill voids and stabilize soil. It can be pumped into the ground beneath the foundation to lift and support it.

In some cases, it may also be necessary to use a specific type of cement, such as high-strength or fast-setting cement, depending on the needs of the repair.

It's important to consult with a professional foundation repair contractor to determine the most appropriate type of cement for your specific foundation repair needs. A qualified professional can assess the extent of the damage and recommend the most effective and long-lasting repair method, including the appropriate type of cement to use.

How do you repair a damaged concrete slab?

Repairing a damaged concrete slab can be a simple or complex process, depending on the extent of the damage. Here are the general steps for repairing a damaged concrete slab:

Clean the damaged area: Remove any loose or broken concrete and clean the area thoroughly with a wire brush and a solution of water and detergent.
Prepare the crack: Use a chisel and hammer to widen the crack to a uniform depth of at least 1/4 inch. This will provide a better surface for the repair material to bond to.
Apply concrete patching compound: Fill the crack with a concrete patching compound, using a trowel to smooth the surface. Follow the manufacturer's instructions for mixing and applying the compound.
Let the compound dry: Allow the compound to dry completely, usually for at least 24 hours.
Sand and seal the surface: Once the compound is dry, sand the surface to make it smooth and level. Then, seal the surface with a concrete sealer to prevent water from penetrating the repaired area.

For larger damaged areas, the repair process may involve using a concrete resurfacer or pouring a new layer of concrete over the damaged area. It is important to follow the manufacturer's instructions and consult with a professional if you are unsure about the extent of the damage or the repair process.
