Services
Underpinning
We reinforce existing foundations using conventional concrete methods and helical pile systems. Our 50+ years of experience ensure appropriate method selection based on soil conditions and structural requirements. All work follows building codes and engineer specifications to prevent future settlement issues.
Helical Anchors
Our helical anchor installations provide tension and compression support for settling structures. We use ICC-ES certified Earth Contact Products anchors with load capacities verified through ASTM testing. This method offers 50% cost savings compared to replacement in many residential applications.
Hillside Restoration
We repair mudslide damage and stabilize slopes using soil nailing, retaining walls, and recompaction techniques. Our crews implement emergency protection measures and permanent solutions that meet geotechnical engineer requirements while minimizing environmental impact through drought-resistant vegetation.
Concrete Slabs
Our concrete repair services include slab replacement, structural decks, and decorative finishes. We use rebar reinforcement and proper subgrade preparation to minimize cracking. Our master finisher ensures durable, aesthetically pleasing results for both functional and decorative applications.
Drainage Improvement
We install French drains, area drains, and swales to prevent water damage to foundations. Our systems divert surface water and groundwater away from structures using proper trenching, piping, and grading techniques to protect against soil erosion and settlement.
