Helitech Concrete Leveling

Whether your uneven sidewalk poses dangerous tripping hazards or you need to raise sunken concrete in your driveway, patio or garage floor, Helitech offers a fast, cost-effective solution. Concrete Leveling Contractors Strongsville lifts your concrete to a safe, stable position at about a third of the cost of replacement.

Traditional repair methods include mudjacking and polyjacking, which use cement slurry or foam to "jack" the slab back up into place. Both processes are time-consuming and messy, but they're also cheaper than replacing the sunken concrete.

Repairing Sunken Concrete Slabs

Whether you have concrete slabs outside your home or at your place of business, keeping them level is important for a number of reasons. Uneven concrete is not only unsightly, but it can also pose a tripping risk for people or vehicles. It can also lead to further damage if left untreated.

Fortunately, repairing sunken concrete is a quick and hassle-free repair process called concrete leveling. This method involves drilling holes and injecting an expandable polyurethane foam to fill voids and lift slabs back to their original position.

Unlike mudjacking, which uses cement mixed with sand to raise slabs, this method is much faster and cheaper. Another benefit is that it doesn’t require any wait time for the mixture to cure. This allows your customers to return to their normal activities immediately. This method also is a better alternative to pouring new concrete, as it addresses the underlying issues rather than just covering them up.

Mudjacking

Mudjacking uses a mud-like mixture of cement, water, soil and sand to lift concrete slabs. Using a nozzle, the liquid-like material is pumped through 2-inch holes in the concrete surface.

The slurry raises the sunken concrete, which is then patched with concrete mix or a concrete topping. It can be used to level driveways, patios, pool decks, porches and sidewalks.

One of the disadvantages of mudjacking is that it requires underlying soil support to keep the lifted concrete in place. This means the heaving and settling caused by erosion or drainage issues can cause the concrete to sink again.

Another alternative to mudjacking is foam leveling, which uses polyurethane instead of slurry. The foam is injected through 2-inch holes in the concrete surface and expands to lift it back into place. The polyurethane doesn’t require a long time to cure, which allows the area to be used again right away. It’s also mold and water-resistant and more durable than slurry.

Polyurethane Foam

Sometimes called "foam jacking" or "poly leveling," this process uses polyurethane foam to lift sunken concrete slabs. It is less invasive than traditional mud jacking and doesn't require any machinery to operate. Its curing time is just 15 minutes, which makes it one of the fastest concrete lifting methods available.

The polyurethane foam used in concrete leveling is a high-density material that's pumped underneath the slab through tiny ports about the size of a penny. It begins to expand immediately, filling in voids and lifting the concrete at the same time. It is made of six main components: polyols, diisocyanates, blowing agents (water or chemicals), surfactants, and catalysts/curatives. Polyols are organic molecules that contain hydroxyl groups, while diisocyanates are isocyanate compounds that react with the OH groups to form polyurethane. The water or chemical blowing agent generates gas, which expands the polymer and creates the foam. Polyurethane is waterproof, which means it won't wash away or degrade over time from weather conditions.

Limestone Slurry

A carbonate sedimentary rock, limestone contains the skeletal fragments of shellfish and other shallow-sea creatures. It also contains the minerals calcite and aragonite, both of which are different crystal forms of calcium carbonate. Gardeners use it in their lawns, contractors build buildings and roads with it, and water treatment professionals insert it to help reduce a high level of acidity in their water systems.

Unlike mudjacking or polyurethane foam, this concrete repair method uses all-natural materials that are safe for the environment. The limestone slurry grout is pumped at low pressure into small holes, which allows for more precise control of the lifting process and limits damage to surrounding areas.

A-1 uses micronized limestone that is sourced from local quarries near each of its franchises to provide the best results possible. This allows them to support the local economy while providing a more consistent product with better engineering properties than conventional limestone powders. This micronized limestone also helps to decrease the permeability of the concrete, which improves its durability and strength.
