Concrete settling is terrible news for commercial or residential properties. When a concrete surface cannot perform their vital functions anymore, swift action is needed to prevent further damage.
The primary cause of concrete failure is sunken soil. Concrete is strong, durable, and reliable, but they are as healthy as the soil that lies beneath them. When the soil below the concrete is unable to carry the weight, the concrete sinks. If the soil beneath the concrete slab is not compacted well enough, or if its maximum load-bearing capacity cannot withstand the stressed the slab is undergoing, failing is inevitable. When there is uneven surface due to sinking soil, the section that has the support of the concrete slab on the floor may begin to crack.
When concrete in our homes, driveways, offices, and warehouses begin to sink, it makes the structure unattractive and prone to hazards and liabilities.
When the soil beneath the surface of your concrete fails, and the concrete begins to sink, owners are often faced with the challenge of finding the most effective method of repair. There are two options in fixing failed concrete – lifting or replacement. For replacement, you will watch the demolition of your expensively constructed concrete work. Then you will have to close work or shift the base of your operation to a new place. The work will take weeks to complete meaning you will have to make do with limited options for the time being. For concrete repair, one very effective method of fixing your sunken concrete is through concrete lifting. Concrete lifting poses a lot of advantages over other concrete repair options. Apart from being less expensive, time-saving, and environmentally friendly, concrete lifting provides additional benefits that include rapid cure time, and a lightweight and waterproof product.
Concrete leveling works for many sunken concrete problems. They include:
- Concrete sidewalks & steps
- Interior floor slabs
- Concrete pool decks or pool surrounds
- Concrete patios & landings
- Sun rooms with concrete floors
- Concrete driveways
- Concrete roadways & parking areas
- Roadways including bridge approach
The use of concrete lifting leaves us with a series of options. Two of the most effective concrete lifting options are foam jacking and Sandjacking.
Polyurethane foam jacking is replacing mud jacking due to its speed, versatility and longevity. Foam jacking involves drilling of a small hole on the sunken concrete for polyurethane foam passing. As the foam expands underneath, it fills the cavity with a structural polyurethane foam. With techniques like mud jacking, the repair could take a few days. However, with foam jacking, concrete can be filled and driven over in just minutes after repair.
Sandjacking is a concrete lifting alternative that is done by lifting sunken concrete with jacks, pipes and braces. No holes are drilled in the slab if both sides are accessible. This method employs the use of dried limestone sand for filling the void. If there is a need to drill holes, they are filled with grout afterwards. Sandjacking is structurally stable and can supply 99% compaction of fill.
Voids beneath concrete are also common when the soils below have settled but the concrete hasn’t settled yet. Both Foam Jacking and Sandjacking are possible solutions for filling the void cavity beneath the concrete to provide structural integrity for the concrete slab to prevent settling and cracking.
Here is What You Need to Note:
When the soil beneath concrete structures fails, it causes an uneven surface, giving way for sunken concrete. If your specific structure shows signs of sunken concrete, call us to help find the primary source of its problem before applying a solution. Concrete leveling is the best repair method for settled concrete. Concrete leveling will not disrupt your workplace and save you money. If any concrete problems arise in your home or work facilities, we are a call away from fixing your concrete. Our team is always available to carry out your repair work to your maximum satisfaction.
