Deep Soil Foundation Repair
Foundation Underpinning in Michigan and Northern Indiana
Industrial Strength Solutions
Ayer’s CG provides deep soil foundation repair for existing structures as well as end-bearing deep foundations for new construction applications, including helical pile and helical tension anchor systems as well as push pier systems for underpinning existing commercial and residential structures.
Helical Piers owe its name to the helical plates welded to the pier shaft. These plates drive the pier into the soil providing anchoring strength as the weight of the foundation is transferred to the pier. Additional sections can be added to the pier until it reaches the necessary depth. Helical piers have a great deal of versatility for stabilizing and restoring foundations and masonry elements.
The Supportworks push pier system utilizes high-strength round steel tubes and a load transfer bracket (retrofit deep foundation repair bracket) to stabilize and/or lift sinking or settling foundations.
The Supportworks push pier system develops a factor of safety against pier settlement by the pier installation methods used and the sequence with which multiple piers are driven and then re-loaded. Piers are first driven individually using the maximum weight of the structure and any contributory soil load.
Helical piles are a factory-manufactured steel foundation system consisting of a central shaft with one or more helix-shaped bearing plates, commonly referred to as blades or flights, welded to the lead section. Extension shafts, with or without additional helix blades, are used to extend the pile to competent load-bearing soils and to achieve design depth and capacity. Brackets are used at the tops of the piles for attachment to structures, either for new construction or retrofit applications. Helical piles are advanced (screwed) into the ground with the application of torque.
