Concrete Leveling

Fix sunken, uneven concrete without the mess and cost of replacement.

Concrete leveling and repair equipment in Dover, NH

What Is Concrete Leveling?

Concrete leveling is a process that raises sunken concrete slabs back to their original position. Over time, concrete can settle or sink due to soil movement, erosion, or poor base preparation. This creates uneven surfaces that are not just unsightly but also dangerous. Trip hazards form where one slab is higher than another. Water pools in low spots instead of draining properly. Doors and windows can stick if the foundation settles. Concrete leveling fixes these problems without tearing out and replacing the entire slab.

The process works by injecting material underneath the sunken slab. This fills voids in the soil and lifts the concrete back up. We use two main methods: polyurethane foam injection and mudjacking. Both are proven techniques that restore level surfaces quickly and affordably. The choice between them depends on your specific situation, but both avoid the disruption and expense of full replacement.

At Brickhaven Dover Concrete, we specialize in concrete leveling for driveways, sidewalks, patios, garage floors, and more. We have the equipment and experience to handle residential and commercial projects throughout Dover, NH. Most leveling jobs are completed in a single day. You can use the concrete within hours of completion. Compare that to replacement, which requires excavation, hauling away old concrete, pouring new concrete, and waiting days for it to cure. Leveling is faster, cleaner, and costs a fraction of replacement.

Leveling also makes sense environmentally. You are not sending tons of old concrete to a landfill. You are not using new raw materials. You are simply restoring what you already have. This reduces waste and conserves resources. It is a smart choice for your wallet and for the planet.

How We Level Concrete

We use two proven methods for concrete leveling. Each has advantages depending on your situation:

Polyurethane Foam Injection

Polyurethane foam injection is the modern approach to concrete leveling. We drill small holes through the sunken slab, usually about the size of a penny. Then we inject expanding polyurethane foam through these holes. The foam expands and fills voids under the slab. As it expands, it lifts the concrete back to the correct height. The foam hardens quickly, usually within minutes. It is lightweight but incredibly strong. It will not wash out or break down over time.

Polyurethane foam has several advantages. The holes are small and barely noticeable after we patch them. The foam is waterproof, so it will not absorb moisture or break down. It adds almost no weight to the soil, which is important in areas with weak or unstable ground. The process is clean and quick. You can use the concrete within hours. Foam injection works well for driveways, sidewalks, patios, pool decks, and garage floors.

Mudjacking

Mudjacking, also called slabjacking, is the traditional method. We drill larger holes through the slab and pump a mixture of sand, cement, and other materials underneath. This mixture fills voids and lifts the slab. Mudjacking has been used for decades and is a proven, reliable method. It works well for heavy slabs and areas where weight is not a concern.

Mudjacking is typically less expensive than foam injection. The materials cost less, so the overall price is lower. It is a good choice for large areas like commercial parking lots or warehouse floors. The downside is that the holes are larger, usually 1 to 2 inches in diameter. The mixture is heavy, which can be a problem on soft soils. And it takes longer to cure, though you can usually use the concrete within 24 hours.

Which Method Is Right for You?

We assess your situation and recommend the best method. For residential driveways, sidewalks, and patios, foam injection is usually the better choice. It is faster, cleaner, and leaves minimal evidence. For large commercial slabs or situations where cost is the main concern, mudjacking can be more economical. Either way, you get a level surface that performs like new. Both methods are far better than living with uneven concrete or spending a fortune on replacement.

Benefits of Concrete Leveling

Concrete leveling offers significant advantages over replacement. Here is why it makes sense:

  • •Cost Savings: Leveling typically costs 50 to 70 percent less than full replacement. You get your concrete back to level for a fraction of the price. This frees up your budget for other projects or improvements.
  • •Speed: Most leveling projects are completed in a few hours to a day. You can use the concrete almost immediately. Replacement takes days or even weeks when you factor in demolition, excavation, pouring, and curing.
  • •Less Disruption: There is no jackhammering, no heavy equipment tearing up your property, and no dump trucks hauling away debris. Leveling is relatively quiet and clean. Your landscaping stays intact.
  • •Safety: Uneven concrete is a trip hazard. Someone could fall and get hurt. Leveling eliminates these hazards and makes your property safer for family, guests, and customers.
  • •Improved Drainage: Sunken slabs create low spots where water pools. This leads to ice in winter, mosquito breeding in summer, and erosion over time. Leveling restores proper drainage so water flows where it should.
  • •Preserves Existing Concrete: If your concrete is structurally sound, there is no reason to replace it. Leveling extends its life by decades. You get more value from your original investment.
  • •Increases Property Value: Level, safe walkways and driveways improve curb appeal. Buyers notice when concrete is uneven or cracked. Addressing these issues makes your property more attractive and valuable.

We level all types of concrete surfaces. This includes driveways, sidewalks, patios, pool decks, garage floors, basement floors, warehouse floors, and more. If it is concrete and it has settled, we can likely level it. We evaluate each situation individually to determine if leveling is the right solution. In most cases, it is.
