Fixing Erosion Under Concrete Slab

A wet concrete slurry is pumped under the slap to raise and support it.

Fixing erosion under concrete slab.

Foam injection is a solution similar to mud jacking but instead of dirt and cement you force polyurethane foam under the slab. There are no structural issues cracks etc above this area. Mix a small batch of concrete mortar and fill in the holes leveling the mortar to the surface of the slab using a trowel. Can anybody recommend the best way to fill this with rocks gravel concrete etc.

Patios don t tend to drain well instead producing runoff and therefore sometimes posing a significant soil erosion problem in home landscapes. With slabjacking a stable grout mixture is injected beneath the surface filling the voids and reestablishing the strength your slab needs to last for ages. The erosion only extends about 6 14 inches from left to right underneath the slab. Slabjacking is used to prevent everything from porch floors to patios and basement floors from shifting.

The foam is a two part product and when you combine the parts it quickly expands and solidifies creating enough upward pressure in the process to level the slab. If your patio causes erosion then taking several. Concrete is a very heavy material in addition to being unable to generate any upward pressure on the slab the added burden on the soil often speeds settling. You can affordably repair erosion under concrete once and for all.

A shortcut repair adding more concrete to level or even out the slab imposes even more weight on the soil increasing the risk of sinking in the future. Turn off the pump and remove the hose once the fill material has reached the level of the concrete slab. To keep it from eroding further and give some support to this area of the driveway. The void is completely filled in at this point.

1 855 752 2522 uses an expanding polymer foam injected under the concrete that fills voids and if necessary raises you re settled concrete back to the proper grade. Filling hollows under a concrete floor is done through a process called slabjacking. For areas of the slab that have settled significantly a process known as slabjacking might be useful.
