Foundation repair system utilizing dissolvable spacers

Abstract

A foundation repair system which employs dissolvable spacers to reduce installation force during pier shimming operations. The system includes concrete piers driven to refusal, topped with pier caps and pier cylinders. A dissolvable spacer is positioned on top of one cylinder, creating a temporary elevation. This allows corrosion-resistant shim plates to be installed on an adjacent pier cylinder with reduced hammering force, decreasing installation impact and preventing pier damage. The dissolvable spacer naturally dissolves when exposed to moisture, leaving little to no residual material. The system may also incorporate galvanized or stainless-steel shim plates for corrosion resistance, and double-stacked pier caps for enhanced load distribution. The method addresses installation force problems that cause pier cracking, while providing long term structural durability.
