Considerations for Your Retaining Wall in San Diego

At Unlimited Drilling and foundations, we have been building block walls in San Diego, along with many other types of retaining walls , such as concrete retaining walls since 1993 and we have just about seen it all.  Ultimately the experience of the retaining wall contractor, the equipment they use, and the quality of the materials will dictate how the finished product turns out.  We have years of experience building retaining walls in La Jolla and all over San Diego, which has arguably some of the toughest coastal retaining wall considerations of any area in the country.  We pride ourselves on getting the job done right the first time and setting expectations on job completion from the word go.
