Cave Creek

Helical piles in Cave Creek, Arizona

Cave Creek sits on the northern edge of the Phoenix area, where foundation trouble usually comes from dry soils reacting to water. The Arizona Geological Survey describes expansive clays that swell when wet and shrink as they dry, and collapsible soils that compact suddenly when wetted or heavily loaded. A leaking irrigation line or poor drainage beside a house can set either problem off.

Helical piers carry a structure past unstable near-surface soil, and they go in without adding the water that often triggers collapse. Typical Arizona uses include foundation repair after settlement, patio covers and ramadas, and ground-mount solar. Frost is rarely a factor in the low desert, so soil strength usually sets pile depth.

Costs and what to ask

According to HomeGuide, helical piers in the U.S. usually cost about $2,000 to $4,000 apiece installed, with most around $3,000. Arizona prices depend on how deep piers must go to get through problem soil and on access around the structure. Our our helical pier cost guide explains the variables. Questions worth asking a Cave Creek contractor:

• Will an engineer design the piers from a geotechnical report, and has the contractor worked on collapsible or expansive soil?
• Will you provide installation torque logs for each pile?
• What shaft size and galvanizing are specified, and how is extra depth priced?
• Who pulls the permit, and what does the warranty cover if a leak contributed to the settlement?
