Retaining Wall Engineering

The wall usually is not the only problem.

DRJ designs retaining systems around the geometry, loading, drainage, foundations, existing conditions, and construction constraints that actually control the project.

Specialty practice

When the concept exists, but the difficult part still needs engineering.

DRJ is frequently brought in after the wall alignment, grading concept, or preferred wall system has already been established. The task is to turn that concept into a stable, practical, buildable system.

Large precast gravity walls
Segmental retaining walls
Geogrid-reinforced systems
Tiered walls
Conventional concrete walls
Wall replacement + repair
Stream / flood-adjacent walls
Rail / roadway-adjacent walls
What gets checked

Stability is only the start.

01

External Stability

Sliding, overturning, bearing, eccentricity, embedment, surcharge, and foundation conditions.

02

Internal + Structural

Block configuration, reinforcement, connections, geogrid layout, concrete, steel, and specialty details where required.

03

Site Integration

Drainage, grading, utilities, slopes, adjacent structures, access, fences, traffic, waterways, and field constructability.

Typical workflow

From concept to something that can actually be built.

Understand

Review the civil concept, wall geometry, geotechnical data, loading, and project constraints.

Resolve

Identify the controlling sections and work through the geometry, stability, and constructability issues.

Document

Prepare calculations, plans, details, notes, and supporting information appropriate to the project.

Support

Respond to reviews, revisions, field questions, substitutions, and construction-phase issues when needed.
