Valentine Corporation's Perma Jack Division specializes in foundation underpinning, stabilizing and leveling in the S F Bay Area utilizing a unique and patented pipe pile system - The Perma Jack System . Since 1978 Valentine Corporation has installed thousands of Perma Jack piles in the greater San Francisco Bay Area. Perma Jacks are installed on both residential and commercial properties to correct foundation settlement caused by a variety of conditions. These conditions range from highly expansive soils, to poorly compacted fill, to improper drainage. In most cases, structures and foundations are not only stabilized, but they are also leveled at little or no additional cost to the owner.

Our Perma Jack System is much faster than the older methods of underpinning and stabilizing because there is less excavating. Jobs take on average, one to two weeks to complete. Additionally, when the Perma Jacks are tested, they are immediately locked off in place without waiting for concrete to harden. Hence, repair time is greatly reduced. Our Perma Jack System also provides minimal disturbance to the owners and occupants of the structure being stabilized.
