Caisson & I-Beam Retaining Wall
Redondo Beach / Pylons, Beam Installation & Land Support

Retaining Wall Contractors
Deep caissons and steel beams for a Redondo Beach retaining wall.
This Redondo Beach project is a structural retaining wall support job for a sloped residential site. Urban Construction is installing pylons, also known as caissons, approximately 30 feet deep, setting steel I-beams, filling the caissons with concrete, and preparing the wall system to support the land and neighboring properties behind the site.
The drone photos show compact excavation equipment, staged wide-flange steel beams, protected access points, and active grading around the wall line. It is the kind of retaining wall scope where careful sequencing matters: layout first, deep support next, then beam setting, concrete, wall assembly, and backfill.
Project Scope
- Pylons / caissons drilled approximately 30 feet deep
- Steel I-beam placement for structural wall support
- Concrete-filled caisson system
- Retaining wall construction for uphill property support
- Tight residential access and staged material handling
- Excavation, grading, and backfill coordination
- Redondo Beach retaining wall contractor project

How the work comes together
A structural support sequence, not just a wall.
Site access and layout
Drone documentation shows a tight residential work area with plywood access protection, staged steel, and excavation paths planned around existing fences, neighboring yards, and the block wall above the site.
Deep caisson support
The project scope calls for pylons, also called caissons, reaching about 30 feet deep. These vertical shafts create the structural support needed before the retaining wall system is built.
I-beam installation
Wide-flange steel I-beams are staged on site and moved into position with compact excavation equipment. Once set, the caissons are filled with concrete to lock the steel in place.
Wall support and backfill
After the posts and concrete are in place, the retaining wall assembly can support the soil and properties behind the site, with backfill and final grading coordinated as the wall progresses.

Retaining wall expertise in coastal hillside conditions.
Retaining wall projects in the South Bay often involve more than block, concrete, and finish grading. When a wall supports an uphill property or works near existing homes, the structure may need deep foundations, engineered steel, concrete-filled caissons, drainage planning, and careful sequencing around limited site access.
On this Redondo Beach project, the visible scope includes a compact track excavator, staged I-beams, protected access panels, active excavation, and a wall line positioned below neighboring properties. That combination points to a structural support project where the below-grade work is just as important as the finished wall.
Urban Construction supports these projects through excavation coordination, concrete placement, retaining wall construction, site protection, and communication with the property owner as the work moves from layout to final backfill.
