After Hurricane Florence and the secondary rains and flooding, it will be time to take stock of your home, foundation, and belongings. Whether or not your home was in the direct path of Hurricane Florence, homes all over the country were hit with the effects and aftereffects of the hurricane. Many of these had flooding and standing water as well. After this, you may notice that your concrete slab is sinking. Whether that’s on your patio, in your garage, or your steps you may find that they have begun to sink and now you need slap repair.
This is a fairly common phenomena! Your concrete slab is sinking or settling because water has deeply permeated the soil and caused it to become unstable under your slab. This is especially true in areas where the soil was not compacted properly and was already a risk. When the soil is not properly compacted, it is looser and easier for water to get into. The water then displaces the soil and causes it to exert pressure against other areas. This is usually most apparent against the side of your foundation walls where cracking and bowing is found. However, in the case of a slab, there may only be the evidence of settlement a few weeks after a big storm–perhaps even longer. Clay soils are even more susceptible to this type of damage.
Luckily, in most cases a slab will not need to be replaced. This saves you a lot of money, time, and energy. There are two main options for slab repair, polyjacking and mudjacking. They are one in the same in most respects, but polyjacking does tend to win out over mudjacking for its quick dry time, minimal holes, and durability. However, mudjacking can be the right choice in other situations.
Polyjacking uses a polyurethane foam which hardens extremely quickly and lifts the slab. It is inserted through small holes drilled into the concrete. No heavy machines are on the lawn either as the foam will be injected through a long tube. After the holes are filled, they will harden to be the same color as the rest of the concrete. Mudjacking is similar, but uses bigger holes and a dirt/mud mixture to raise the slab. This takes longer to harden, and it may eventually need redone in the future. Both can be good choices, as they will raise your slab and keep it there, depending on what you’re looking for and what your budget is.
