Hydro-Static Drainage // Natural Stone
SKU: MFD-GAB-2024

Engineered
Permeability.

San Diego's premier gabion retaining wall contractors. Where concrete dams water and fails, gabion walls channel it safely through. Natural stone captured in galvanized steel mesh creates a fully permeable drainage system—eliminating the hydrostatic pressure that causes 90% of retaining wall failures across Southern California hillsides.

Wire Gauge 8 GA / 4.0mm
Mesh Opening 3" — 3"
Drainage Rate 98.7%
Design Life 75+ Years

Pressure vs. Permeability

Watch water behavior in real-time. Concrete traps and builds pressure. Gabion drains and dissipates force.

Living Architecture

Gabion walls don't fight nature—they integrate with it. Over time, they become habitat.

Soil Stabilization

Root systems penetrate stone matrix, creating natural reinforcement that strengthens over decades.

Erosion Control

Dissipates water energy across thousands of contact points, eliminating scour and undercutting.

Wildlife Habitat

Stone crevices provide microhabitats for beneficial insects, lizards, and native plant species.
