Foundation Underpinning in San Rafael

underpinning methods in San RafaelThis specific job in San Rafael, California was bid by three different foundation contractors to underpin and re-level the structure. With 85% of the house being within a 1/4-inch off level and about 15% of the home experiencing some heaving due to poor drainage, it was in serious danger.

Two other contractors bidding on the job suggested to underpin and lift the entire foundation to the highest point of the house. We won the bid based on our engineer’s recommendation to underpin the heaved area of the foundation, undermine that area, and then lower the affected part of the foundation.

With the installation of six resistance piers, we successfully underpinned and lowered the heaved area and saved the homeowner approximately $22,000 in the process!
