Perma-Jack is a frictionless steel pier system used to stabilize the foundations of settling structures, such as houses or buildings and some porches. Steel piers are driven to bedrock, or equal load bearing strata, providing unvarying support, unlike many other piers and anchoring systems. Perma-Jack Company introduced the first remedial steel pier stabilization system available. The system was invented in 1974 and patented by George Langenbach, the founder of Perma-Jack Co., and has remained a privately owned business over the last 34 years. The Perma-Jack System has provided a dependable, quality, low impact solution for foundation stabilization. While others make claims, Perma-Jack has been the most reliable and the longest operating remedial steel pier system in use today.
