Why Choose Us

Built for load and longevity

  1. Structural thinking, not cosmetic fixes
    KOM treats retaining walls as load and drainage systems first. The goal is a wall that stays stable under surcharge loads, soil movement, and water pressure.
  2. Repair vs replacement guidance you can trust
    Not every failing wall needs full replacement. KOM evaluates movement, drainage, backfill, reinforcement, and site loads to recommend the safest path with clear reasoning.
  3. Drainage is planned from the start
    Most wall failures trace back to water. KOM scopes drainage, backfill, and discharge paths early so the wall performs through wet seasons and irrigation cycles.
  4. Coordination with engineers, inspectors, and stakeholders
    When engineering is required, KOM works in alignment with the approved drawings and inspection requirements so the project stays compliant and predictable.
  5. Documentation that supports property records
    HOAs and commercial owners often need records for maintenance files, insurance coordination, future sales, and compliance. KOM provides clear closeout documentation.

What We Do

Retaining Wall Services We Provide

  • Retaining Wall Inspections and Condition Assessments
    For walls showing bowing, cracking, separation, washout, or settlement. KOM checks wall alignment, drainage performance, backfill conditions, and risk impacts to nearby assets.

  • Commercial Retaining Wall Repair
    Best when movement is limited and stable and the root cause is correctable. Common repair scopes include drainage improvements, partial rebuilds, reinforcement work, wall realignment, and surface restoration.

  • Retaining Wall Replacement and Rebuilds
    Required when the wall is structurally compromised, movement continues, reinforcement is missing, or the wall supports buildings, drive lanes, slopes, or key infrastructure. KOM plans demo, excavation, rebuild, and restoration as one controlled sequence.

  • Block Retaining Wall Installation for Commercial Sites
    Segmental block systems can be a strong commercial option when built to spec. KOM installs systems with proper base prep, reinforcement where required, geogrid integration, and drainage details that relieve hydrostatic pressure.

  • Engineered and Structural Retaining Wall Builds
    For walls that function as structural elements and support surcharge loads. This includes reinforced segmental systems, load bearing walls, hillside stabilization, and grade change management around buildings and access roads.

  • Drainage and Water Management for Wall Performance
    Drainage is often the deciding factor in wall life. KOM scopes weep paths, drain lines, gravel zones, filter fabric placement, discharge routing, and water control measures to reduce pressure buildup and soil saturation.

Our Process

Engineered from ground up

Built for compliance. Executed with control. Handed off trade-ready.

1) Site Walk and Scope Review
KOM reviews wall type, site grade, nearby structures, utilities, access limits, and visible failure signs. The goal is to identify what is happening and what could fail next if left untreated.

2) Repair vs Replacement Recommendation
KOM explains what can be stabilized, what must be rebuilt, and why. Recommendations are based on movement severity, load demands, drainage failures, and constructability on the site.

3) Engineering and Permitting Coordination
If the wall height, loads, or jurisdiction require it, KOM coordinates with engineers and aligns the scope to permitting and inspection requirements. The build plan follows the approved design intent.

4) Build Sequencing and Risk Controls
KOM plans excavation, shoring needs if applicable, material staging, drainage installation, reinforcement steps, and restoration. This reduces surprises and protects adjacent improvements.

5) Construction and Closeout Documentation
KOM completes the work, verifies drainage function, restores affected areas, and provides documentation suitable for HOA files or property management records.

Retaining Wall Services FAQ

Most failures trace back to water and pressure. Common causes include poor drainage design, hydrostatic pressure buildup, improper backfill, inadequate compaction, missing or undersized drainage systems, clogged outlets, and construction shortcuts that ignore reinforcement requirements. Even a strong wall system can fail if water cannot exit the wall zone.

Yes, but commercial block walls often require reinforcement, geogrid systems, and tighter controls on base prep, backfill, and compaction. The wall must be selected and installed to match height, site loads, and drainage conditions. KOM installs block systems as engineered retaining solutions, not just landscape walls.

Often, yes. Requirements vary by jurisdiction and depend on wall height, location, and load conditions. Walls supporting slopes near buildings, parking areas, or public access areas are more likely to need engineering. KOM coordinates with engineers and aligns construction with local approval and inspection requirements when needed.

Rapid changes in lean, new or widening cracks, separation at joints, sudden sinkholes or washout behind the wall, water actively pushing through joints, and settlement that impacts sidewalks, curbs, or utilities can indicate higher risk. KOM can assess these conditions and advise on immediate stabilization steps.

Yes. KOM can provide scope details, photos, basic closeout notes, and other documentation that helps with HOA records, insurance coordination, and long term maintenance tracking.
