Retaining Wall Geotechnical Engineering

What This Engineering Scope Covers

• Active and passive lateral earth pressure parameter determination
• Equivalent fluid pressure for wall design
• Allowable bearing capacity at wall footing depth
• Sliding and overturning stability analysis
• Seismic earth pressure increment for high-seismic zones
• Surcharge loading from traffic, structures, or equipment
• Drainage design recommendations behind retaining walls
• Drainage fill specification to prevent pressure buildup
• Native soil vs. engineered fill parameter differentiation
• Geotechnical parameters for wall design per site-specific conditions

How Apex Grid Handles This

Apex Grid Engineering is a multi-discipline firm with multi-state PE coverage confirmed per project. We provide retaining wall geotechnical engineering as a standalone service or coordinated with structural, MEP, civil, and geotechnical engineering under one contract. Our engineers produce PE-stamped permit packages that building departments accept — and we respond to plan check comments as part of the scope.
