You can avoid this expense if you do it yourself with the help of a jacking pump which can raise the concrete slab to the needed level.
Do yourself concrete lifting.
Mix a small batch of fast setting concrete.
Polyurethane foam is then injected under the slab filling voids and raising it to the correct level.
Geolift works in three steps.
You should also get a steel.
Injection holes are strategically drilled into the concrete slab s that requires lifting.
Polyfoam is stronger and longer lasting than traditional mudjacking.
Lifting a sunken slab may be necessary to level the surface.
High density polyurethane foam is injected into holes that expand to lift and level the sunken concrete.
With a concrete drill or masonry bit drill small holes into the sunken area and slowly pour a thin mixture of cement into the holes.
And yes it is a foam just like your beloved spray foam.
In time however concrete slabs can crack or sink due to pressure or from movement during settling.
Geolift can help to lift existing concrete surfaces and fix those problem areas around your house with much less labor.
You will want to add some reinforcement wire to prevent fracturing and probably use a surface preparing glue.
Otherwise you could crack the concrete.
Use diamond tipped core drill to bore several large diameter holes through slab.
Add some of the concrete dust removed from the holes after drilling to the mix to tint the mix the same color as the slab.
Foam jacking also known as polyfoam or polyjacking is a modern version of mudjacking that levels concrete slabs in a less invasive way.
Fast setting concrete is necessary to patch the holes when you re finished filling them up.
That ll allow the sunken slab to lift up.
Cut through slab with gas powered saw fitted with 12 inch diamond blade.
Basically you clean the concrete buy a bag of cement mix it up and dump it on top finish it yourself.
Place the concrete into a grout bag and inject it into the holes filling them up to the level of the slab s surface.
Geolift works for driveways sidewalks patios garage floors even pool decks.
The equipment is contained in a trailer rig with a long hose capable of reaching direct to the concrete slab location.
Use the brick chisel and sledgehammer to undercut any edges of the sunken concrete as necessary.
Concrete lifting with a small sledge hammer brick chisel and drill this is another method for doing it yourself.
Hack to fix sunken concrete.
