Concrete foam lifting is ideal for Denver homeowners who need to lift concrete slabs, sidewalks, driveways, or anything else that needs to be raised. It’s important that sunken concrete is repaired to prevent injury and improve visual appeal. Learn more about concrete foam lifting vs mudjacking and why foam lifting is our preferred method.
How Does Concrete Foam Lifting Work?
The concrete foam lifting process involves a technician drilling strategic holes in the concrete and using special hoses to pump polyurethane foam through the holes to stabilize the soil underneath and lift the concrete slab. The foam expands and completely fills voids below the concrete surface, raising it back into place.
It’s the preferred method over traditional mudjacking, which has a similar process except it uses a ‘slurry’ mixture of water, dirt, and cement. Other downsides of mudjacking are that it requires heavier equipment and bigger drill holes, and underground water retention can wash out the mudjacking slurry.
Advantages of Concrete Foam Lifting in Denver
At Concrete Repairs Denver, we specialize in concrete foam lifting because it offers numerous advantages over mudjacking. Here are the most notable benefits of using foam to lift sunken concrete:
Polyurethane foam takes just 15 minutes to cure, which means the concrete surface can be lifted and returned to use once the process is complete. Mudjacking, on the other hand, typically takes a day or two to cure.
Smaller drill holes
Foam lifting requires fewer drill holes and the sizes of the holes are also smaller. A mudjacking hole size is 2-3” whereas a foam lifting hole size is 3/8-5/8.” This makes concrete repairs more discrete and requires less labor.
As mentioned earlier, mudjacking slurry can wash out from underground water retention due to heavy rainfall, poor drainage, and underground water pipes. Polyurethane foam is hydrophobic, which means it repels water and stays hard in contact with moisture.
Smaller, lighter equipment
Polyurethane foam weighs much less than mudjacking slurry, which is made of water, dirt, and cement. Since the material is lightweight, the equipment is smaller and lighter too, allowing our team to lift concrete surfaces in narrower spaces like a sidewalk between buildings.
No soil compaction
Concrete foam lifting has a high strength-to-weight ratio, so it puts less pressure on the soil beneath the concrete surface while increasing load-bearing capacity. This is particularly important for supporting the weight of a concrete driveway with a vehicle parked on it.
Compared to mudjacking, foam lifting is a faster and easier process. The smaller, lighter equipment requires fewer technicians, saving on labor costs.
Lift and Level Your Sunken Concrete
Elevate the safety and appearance of your sunken concrete slab with professional concrete foam lifting. In less than an hour, you can have a beautifully level surface that reduces the risk of injury and makes your home’s exterior more attractive. Since concrete foam lifting is newer than mudjacking, relatively few companies have the equipment and expertise to do it. Concrete Repairs Denver does!
