Retaining wall contractor Los angeles & Southern California
Suncore Engineering and Construction builds retaining walls that support grade changes, protect structures, and manage water flow. From new construction and ADU sites to repairs and hillside corrections, we focus on stable foundations, clean finishes, and jobsite coordination that keeps work inspection-ready and moving forward
What We Do
Retaining walls are not just about appearance—they’re about stability and water management. We help owners, contractors, and developers install retaining wall systems that support soil loads, create usable space, and reduce erosion and drainage issues. Our team coordinates site prep, base work, wall construction, and practical details that make the wall perform long-term.
Where Retaining Walls Are Used
Retaining walls are commonly used for hillside lots, yard leveling, driveway and access support, ADU site preparation, slope corrections, and property improvements where space or grade changes need stable support. We also support post-damage and repair scenarios where soil movement or drainage issues have created wall failure concerns.
What Makes a Retaining Wall Last
A retaining wall performs best when the base is prepared correctly, alignment is consistent, and drainage is treated as a core requirement—not an afterthought. Proper backfill, compaction coordination, and grading transitions help reduce hydrostatic pressure and improve long-term performance. If the wall supports higher loads or has complex site constraints, early coordination with the design team prevents costly changes later.
Retaining Wall Services We Provide
New Retaining Wall Construction
We build new retaining walls for grade transitions, yard leveling, driveway support, and site development needs, aligned with the project requirements and approved plans.
CMU Block Retaining Walls
CMU walls are a common, durable option for many sites. We support layout, block installation, reinforcement coordination, and a clean finished look.
Poured Concrete Retaining Walls
Concrete retaining walls can be a strong solution for tight spaces, higher loads, or performance-driven projects. We support formwork coordination, reinforcement readiness, and inspection-aligned pours.
Segmental Block / Gravity Wall Systems
For many landscape and site applications, segmental block wall systems offer a clean and practical solution. We coordinate base prep, leveling, and consistent alignment.
Drainage & Backfill Coordination
Drainage is often the difference between a wall that lasts and a wall that fails early. We coordinate gravel backfill, drain line placement (as required), and grading transitions to support proper water flow.
Retaining Wall Repairs & Rebuilds
If a wall is leaning, cracking, or showing movement, we can evaluate the site conditions and support repair or replacement work based on the project scope and requirements.
Our Process
We begin with a walkthrough to review site conditions, grade changes, access, and the purpose of the wall. Next, we define a clear scope and coordinate sequencing with related work such as grading, utilities, and concrete so the wall construction fits the overall schedule. During execution, we focus on base preparation, consistent installation, and drainage/backfill coordination tied to the project requirements. Finally, we support inspection readiness and turnover by keeping the work organized, clean, and aligned with the approved scope.
Why Suncore Engineering & Construction
We approach mission-critical builds with an engineering mindset that prioritizes buildability, sequencing, and documentation. Our team is field-ready for concrete, site work, and interior buildouts, and we’re structured to coordinate alongside MEP and IT teams with clear communication and predictable execution. We operate with safety, compliance, and inspection readiness as a baseline, and we move fast on walkthrough scheduling and next steps.
Frequently Asked Questions
What type of retaining wall is best for my property?
It depends on height, soil conditions, available space, and the intended load. After a walkthrough, we can recommend the most practical wall type for your site.
Do retaining walls need drainage?
Most retaining walls require drainage considerations. Managing water behind the wall is critical to long-term performance.
Can you repair a leaning or cracked retaining wall?
Often yes—depending on the cause and condition. Some situations require rebuild or replacement, especially if movement is significant.
Do I need permits for a retaining wall?
Some jurisdictions require permits depending on wall height and location. Requirements vary by city and project scope.
How long does retaining wall construction take?
Timeline depends on size, access constraints, excavation/base prep needs, and inspections. After a walkthrough, we can provide a schedule range.
Do you work on hillside lots or tight access sites?
Yes—scope depends on site conditions and safety requirements. A walkthrough is the best way to confirm feasibility
