Unbeatable Advantages You’ll Love
- ✓ Installs in a weekend — no contractor required. Drive the ground pipes, drop the posts, slide in the panels. No mortar, no concrete footings, no digging.
- ✓ 12,000 psi — roughly 3× stronger than standard concrete. Every panel is glass-fiber reinforced and engineered to handle soil pressure, freeze-thaw cycles, and decades of outdoor exposure.
- ✓ Maintenance-free for 50+ years. Unlike timber (rots), steel (rusts), or standard block (spalls), GFRC holds its finish and structural integrity season after season.
- ✓ Looks like natural stone. Costs a fraction. Four premium finishes — Stackstone, Corten Steel, Limestone, and Brickyard — that most people assume is real quarried stone.
- ✓ Order exactly what you need. The calculator above builds your component list to the foot. No minimums, no waste, no guessing.
Site & Installation Requirements
Ground pipes must be driven a minimum of 36" below grade. Account for this when planning in frost-heave climates.
Site soil must support a minimum of 1,500 psf. Expansive clay, saturated soils, loose fill, and similar unsuitable soils require remediation before installation.
Excavate a trench 8–12" wide and at least 6" deep. Backfill with compacted granular material (stone dust) before driving ground pipes.

The HomeBridgePC GFRC Retaining Wall Post is the structural backbone of the Garden Retaining Wall System. Cast from high-strength GFRC in a limestone finish, each post accepts a driven galvanized ground pipe through its center channel for secure anchoring, then receives wall panels in its side channels to form the wall face.
Two Post Types
- Inline Post — Accepts panels on two opposing faces. Used for all straight runs between the start and end of your wall.
- Corner Post — Accepts panels on two adjacent (90°) faces. Used wherever your wall changes direction at a right angle.
Installation
Drive a 1" Schedule 40 galvanized ground pipe (sold separately) into the soil at each post location using the Homebridge Driving Mandrel (sold separately). Slide the GFRC post over the pipe — the pipe runs through the post's center channel and locks it plumb and secure. No concrete footing required. No digging. Once posts are set, panels slide in from the top.
