We are currently working on a brick addition on a home in Walnut Creek. The foundation settlement seemed to be caused by the weight of the structure on a spread footing build in poorly compacted fill. The area has settled over 3-inches in a span of about 16-feet. Because of the weight of the structure the Earth Contact Products model-350 steel resistance pier was used for the added loads. With a total of 13 piers installed to an average depth of 30 feet and individualy load tested to 35,700 lbs, it should be leveled within the week.
