Ultimately, the answer to the question: “Can All Concrete Be Restored?” is no. What we do in this situation once this has been done is void fill the area in order to fill any gaps and airspaces to lock in the aggregates in order to halt any water or critter infiltration into the affected area(s). If there is enough access from the sides, we also recommend that you fill the area with as much 1/4 down limestone as possible prior to requesting a void filling estimate. This must be done from above (injecting the product through the top of the slab with injection holes) if there is no complete access from the sides. If you are only worried about a loss of aggregates and you do not need any lifting done, we recommend void filling with our stabilizing foam systems to lock in your aggregates and keep out any water or critter infiltration. If you have a structural pour that needs to be raised, you will need to contact a foundation specialist to inspect and mechanically raise or replace your structural slab. This is most common with concrete staircases, & garage and basement floor grade beams and footings. If you are able to ask your home/building contractor whether or not it is a structural pour, we advise you do so for your own future reference in case you notice settlement. This makes it a structural pour.įootings and grade beams may have been poured with screw piles, but poured concrete slabs would only utilize screw piles if they were meant to be structural pours. If your concrete was poured on a pile (also known as a screw pile, screw anchor, or a helical anchor), this means that you have a ground anchoring system attached to a slab. Structural Pours/Slabs Utilizing Helical Piles: If you are unsure on whether or not you have a poured, slab-on-grade concrete slab, please visit our gallery to view some photos and you will know right away once you see one of our photos. A mudjacking or tindlestone mixture will not work on these either. Slab-Jack Kings uses polyurethane raising, levelling, void filling and stabilizing foam systems that are designed specifically for application and use beneath poured, slab-on-grade concrete slabs. You will need to contact a landscaping company in order to do this as this involves mechanical raising and levelling. Patio Stones/Landscaping Bricks, Asphalt, Etc: They want to move in the path of least resistance, which means that these gaps and broken sections will not only allow the product to seep upwards towards the surface of your concrete, but they will also likely make it worse.Ĭoncrete itself is not strong enough to withhold the pressure of a lifting product on its own when it is not properly reinforced with steel rebar. The reason being is because concrete raising materials cannot defy gravity. Unfortunately when your concrete is too broken up, has too many larger gaps that are too close together, your concrete was not poured thick enough, too narrow or with not enough-no rebar, we cannot lift it. Broken or overburden concrete with little-to-no rebar reinforcement: We usually recommend these over concrete staircases in the majority of the situations like yours. This would also be another cost-effective alternative solution for you. If you’re finding you’ve had these settlement issues only over the past few years, installing a wooden staircase, as opposed to a concrete staircase would definitely release such a heavy burden on this unstable soil area. We recommend removing your hollow cast or precast step and replacing it with another staircase. However, concrete raising materials for concrete lifting are made specially to lift poured concrete slabs and simply attempting to lift staircases like these with concrete lifting material can cost almost as much as replacement would be due to material cost and ends in breakage of the step or staircase itself, or your house foundation. If the step or staircase were sitting on top of a poured concrete slab, such as a patio, landing, driveway, etc. If you cannot see a slab beneath it then that means it would be tied into the house wall or it might also be fastened with a helical pile at the base. Unfortunately we aren’t able to lift staircases like this. Precast or hollow cast steps and staircases: Can All Concrete Be Restored? When is a slab too damaged to raise vs replace it?
