Certainly! The foams we use are are particularly engineered to lift and expand using the substrate as well as the surrounding soil as a springboard. Our foams are Department of Transportation (DOT) approved, and our services have been requested numerous times to repair highways and roads. As it contracts and expands, the foam pushes against the surrounding soil walls as it expands and contracts. It will lift the slab based on the amount we inject.
We use foams that are particularly engineered to solve this issue. The foams are permanent, and they waterproof as well as expand in the surrounding areas so that they can seal off the cracks and gaps caused by moving and shifting soil. Additionally, we inject to fill the cracks and gaps in the foundation that have been a result of a moving and shifting foundation.
Also, we can treat an entire exterior wall by performing a task known as "Curtain Grouting". We probe the soil surface with the use of pipes from the top as well as inject the foam through the pipes, which seals off the walls below grade. The foam amazingly expands at 1500 psi, and it coats the exterior wall, which establishes a permanent waterproof seal.
Yes, by replacing it. But it cannot be addressed with a foam injection. Our specialized equipment and materials will only raise and lift solid slabs that have dropped or fallen as a result of soil erosion underneath the slab, thus causing it to drop as well as fall. The foams are pressurized upon injection and can escape through the cracks as well as fracturing, thus "blowing out" the pieces of foam and concrete. Frequently, one must replace the slab when slabs are splintered, broken, and fractured.
It can occur again, and it depends on the scenario as well as your particular situation. A factor caused the soil to erode in the first place. Once we lift a slab back to its original position and fill the void, water can proceed with coming in after the fact and continue to erode the soil around the foam. The problem of the water source must be handled by installing a french drain or redirecting the water. We are skilled at inspecting, analyzing, and advising properly no matter the situation.
We certainly can! This is one of our many specialties. The deterioration of a bulkhead or seawall is a total nuisance and can be very expensive when doing a traditional repair or replacement.
We use our resin foams and can inject numerous feet in the ground filing to seal off voids that arose at the base of the seawall where water is coming in underneath and washing soil out and away. This is usually a consequence of tide changes, rustling, moving water, and other man-made as well as environmental problems.
If the water comes in from a failed seawall in of itself, then we can repair that problem too. This is generally caused by the rustling, moving water, tide changes, and other environmental and/or man-made issues.
Should the water be coming in from a defective seawall in of itself, then we can repair that also. We utilize what is known as a "Curtain Grouting" technique, which involves inserting rods in the ground as well as injecting through the rods with pressurized foams. The foam is injected at 1500 psi while coating and plastering all of the seawall by expanding as well as sealing off any voids or cracks in the seawall structure.
