Almost all concrete driveways and walkways will eventually sink over time. This can be due to excess water, improper compaction and simply the weight of the cement. This produces uneven concrete which causes a tripping hazard, creates an unaesthetic curb appeal and can cause potential water damage as uneven concrete can direct water towards the building’s foundation.
Concrete Lifting has many names including mudjacking, slabjacking, and polyurethane concrete lifting. Different methods can be used, but Concrete Experts uses the latest polyurethane technology that is faster, stronger, and can be done with much less intrusion into the concrete than with traditional mudjacking. Here are some of the many benefits:
In order to lift the concrete, small holes must be drilled into the existing cement in order to pump the material beneath. With mudjacking, the holes can be almost 2 inches in diameter. Our polyurethane system requires much fewer holes that are only 5/8 of an inch and can be spaced much further apart.
Polyurethane foam is waterproof, preventing further damage. It is incredibly strong and durable, yet light- weight which can help to precent sinking problems in the future.
Polyurethane is pumped beneath the concrete in liquid form and is therefore able to spread further and more fully to fill the void. This also allows us to lift the concrete more evenly as opposed to mudjacking which lifts from one point. This means the likelihood of the concrete cracking is much less.
Polyurethane will not expand or contract. The more traditional mudjacking uses a slurry mixture which is water absorptive, meaning that when water is in the ground and it freezes it can displace the soil creating voids. With polyurethane in the ground there will be less movement of the ground during extreme temperature change.
