Sealing joints fills and secures gaps or cracks in concrete, providing protection through a weather-tight seal. This prevents damage from moisture, freeze/thaw cycles, and weed growth. In some cases, it can also help prevent further settling of the concrete slab, depending on if there are underlying factors.
Some situations require more than a sealant. If you are suspicious of active movement in the foundation or structure, pushing a flexible sealant into cracks and hoping it will stop the damage is not the best solution. This will not address the core of the problem. Sealants can hide ongoing movement and can tolerate small increases of cracking, but it will not withstand major issues underneath. If a concrete area has had sealant applied before and the cracking continues, it makes an assessment of the area much more difficult. Only a professional will be able to address these situations and understand what else may be going on. Sealant does not fix a structural problem, and it’s critical you address the underlying issues rather than attempt to cover a big problem with a sealant. If a foundation is settling actively or there is frost heaving present, call in a professional to help. In many cases, sealing cracks and joint sealing can mitigate the problem, but soil issues such as poor drainage will need further repair.
