What is under the ground here

Sampled inside the Fontana city limits, the USDA survey reads Tujunga at about 80 percent of the survey, with Quarries alongside it. By texture that survey runs 100 percent sand. Weighted linear extensibility runs 1.5 percent, which is the figure USDA turns into a low shrink swell rating.

The typical house dates to 1988, and the single biggest block of the stock, 13,754 homes, went up in the 1980s. The 17,256 homes finished before 1980 are the ones where drainage was rarely engineered and backfill was rarely compacted. Mortgages sit on 81 percent of the owner occupied homes in Fontana.

What California customers say

Excellent Company. I had our foundation stabilized using deep injection polyurethane. They came out gave me a timely estimate, coordinated when the work was going to be done. On the day of project, Stephen did the work. Extremely tidy and explained what he was doing thoroughly. When he was finished, he left the jobsite spotless. Far exceeded my typical contractor expectations.

In a world where everyone is out to get your money Jason provided me his honest assessment of the repair I needed which was going to end up being a huge risk for me if I went through with his services. I appreciate Jason and his transparency on all the risks surrounding my project and how he was truly looking out for me. Thanks again Jason I appreciate your punctuality and professionalism. I wish the repair made more sense for me to follow through with your services but if anything comes up in the future I have you guys locked in.

I'd like to commend the team at Dalinghaus Foundation Repair for a job well done repairing spalling in our stem wall in Tucson, AZ. Ted provided our inspection and proposal, maintaining good communication without undue pressure throughout our decision-making and permitting processes. Jaime coordinated with local permitting and Lesley kept us informed as to processes, payments and scheduling. Our construction team consisted of Thomas, Josh, and Desmond who arrived ready to work and on-time. They were professional, competent, courteous and kind, receptive to our questions, efficient in their work and thorough in their clean-up. We are grateful to the entire team at Dalinghaus for their help in preserving the integrity of our home and recommend their services without reservations.
