What we build
Services
Storm drain, box culverts, channels, bridges, retaining walls, pump stations and structural concrete, self-performed by our own crews.
Ready to roll up our sleeves and get to work
For 45 years, Slater, Inc. has built storm drain and structural concrete for agencies, developers, contractors and subcontractors across Southern California. Over that time we have built the crews, the fleet and the material inventory to start your project quickly and finish it without costly delays.
Our multiple crews let us meet ambitious schedules, our long supplier relationships keep materials moving, and our reputation with regulatory agencies helps keep approvals and compliance on track.
