About Us

Since 1995 Hillside Companies has specialized in designing and constructing a variety of wall solutions for our customers.

Hillside has successfully completed many projects ranging from residential to complex, highly challenging commercial and public works construction.

Developers, architects, home builders, commercial and industrial customers are just a few of the clients Hillside works with. Contact Hillside for a complimentary review of your upcoming retaining wall engineering, design, or construction project.

Hillside has constructed millions of square feet of retaining walls in Southern California. Counties include San Diego, Riverside, Orange, Los Angeles, San Bernardino, Ventura, Santa Barbara, Imperial, Kern, and San Luis Obispo.

We design site-specific solutions to meet every need and application. For example, at the Hartley residence, Hillside designed and built 3 different wall systems (Keystone, Vista DSM & CMU) to meet the site constraints. Or the Mammoth Profession Center in Corona where Hillside designed and constructed Earthstone Walls, Keystone Walls, and Cast-in-place Walls. We contract for the grading, the street improvements, the site drainage, and wall waterproofing. Hillside is your one-stop-shop.

MSE Retaining Wall Design, Installation & Engineering

Hillside Companies specializes in the design and engineering of segmental retaining walls (SRW), gravity retaining walls, screen walls, and dry stack masonry (DSM) retaining walls. When our design team reviews a project, our primary goal is to ascertain which retaining system is best for that project. Often, the best solution includes two or three different retaining wall systems.

We are very interested in your project. Do you have walls already laid out on the plan and need engineering? Let us provide the engineering services for you. Do you need help with the site design to determine how to best retain the varying cut and fill situations on the site? We can help layout the walls to maximize site area, balance the site, or design the site to include more cost-effective fill walls while reducing the more expensive cut walls. Depending on the site’s geotechnical parameters, we can also design less expensive gravity cut walls where cast-in-place or shoring walls are proposed.

Hillside has designed projects for public works agencies, including the County of San Diego, the City of Los Angeles, the City of San Diego, and Fullerton. We have designed school/DSA projects for San Diego State University, Garfield High School, and Bella Vista Elementary School – Palm Springs, to name a few. Our scope ranges from multi-tract development like Brasada for Brasada Land, Altair, and Chapman Heights for William Lyon Homes to a single-family lot like the Mills residence.

Basin Walls

Detention ponds and extended storage basins provide practical solutions to national, state, and local requirements for stormwater runoff control and management. We design and build mechanically stabilized earth (MSE) retaining wall systems that offer innovative, cost-effective solutions to increase storage volume while minimizing the impact on usable land.

Slope Repair

For more than 15 years, we have performed mitigation for landslide and failed slopes throughout Southern California. From small backyard repairs using an engineered heavy duty pipe and board system, repairing a slope using structural geosynthetic reinforcement (GSR), retaining walls, or installing caissons and grade beams for more extensive landslide repairs…we are the answer.
