Thank you for your interest in our products and services. Our company was founded in 1980 and specializes in structural repair of both residential and commercial buildings, including the shoring and lifting of settling foundations, and pre-installation for new construction. Our specialty is the installation of the CHANCE® Helical Pier® Foundation System. KNOTTS CONSTRUCTION INC. is the Delaware, PA, and New Jersey installer for CHANCE® Helical Pier® components.

The patented, pre-engineered Helical Pier® makes old concrete and pipe pier support systems obsolete, providing a no-stress installation with minimal under-digging of the building. The Helical Pier® is drilled independently of the structure and provides an accurate reading of soil quality as it is driven. The Helical Pier® is effective in all types of soil, taking the worry and guess work out of structural underpinning. Contact us!
