When foundations begin to sink or fail, repairs are needed. Typically, repairing a foundation offers a more cost effective solution than completely replacing a foundation. One of these repair solutions is to add concrete pilings. To put it simply, concrete pilings are concrete columns that are pushed in to the ground, underneath your existing foundation, in an attempt to strengthen and level out that foundation. While these types of pilings are most commonly used by residential homeowners for outdoor patios and deck construction, they are a viable option for foundation repair as well.
