Lifting Settled Pavement Slabs/Void Filling Using Slabjacking or Pressure Grouting
Our specialized slabraising system is an effective, inexpensive alternative to concrete replacement.

Our company can raise and stabilize settled concrete in streets, parking lots, driveways, sidewalks, warehouses, garages and offices. We can eliminate trip hazards, uneven joints (in warehouse floors) and standing water.

Most concrete can be raised with the cost of raising being less than half the cost of replacement.

Our conditional guarantee is for two years, double the industry standard for new concrete.

Other Services: In addition to raising settled concrete, we also do void filling of buried tanks, cement block walls, abandoned or discontinued pipes.

Advantages of Concrete Raising over Replacement

Immediate Access: You can drive on concrete that we have raised in three to four hours. You can walk on raised concrete immediately.

No Re-landscaping: We do not disturb existing landscaping.

Cost Effective: On third to one half the cost of replacement.

Quick: Because we raise your existing concrete, we do not have to tear out old concrete, haul it away, grade the area, set forms, lay wire mesh, pour and finish, wait for the concrete to cure, tear off forms and replace landscaping. We are done in a fraction of the time. Use of the area is only interrupted for a short period.

We can perform work in a clean and safe manner inside offices and warehouses, often completing our work on weekends or during the night. Your operations are not interrupted.

Here’s How Slabraising Works

A soil or sand and cement slurry is pumped under pressure into small holes drilled through the concrete slabs. The “slurry” displaces air pockets, water and water saturated materials, raises the slab and leaves a firm, permanent sub grade. When the slab has reached its proper grade, the holes are patched with high strength, quick setting cement.

As a preventative measure, in swampy or land fill areas, the process helps stabilize the sub grad for streets, parking lots, walks, warehouse floors etc., before noticeable settlement and cracking have a chance to occur.

One Typical Example: In a parking lot or street when it is raining, you can sometimes observe a fine spray of water or bubbles coming up through the joints when vehicles pass over the area. After the rain, there are small amounts of sand around the same joint. Water is being pumped (as a result of the flexing of the concrete) from a small void under the concrete and is carrying bits of sand etc. with it. With each rainfall, the void grows bigger and the flexing gets worse until cracking and failure of the concrete occurs.
