The HomeBridgePC GFRC Retaining Wall Panel is the foundation of the Garden Retaining Wall System — a premium precast concrete panel that slides into place between driven posts to create a clean, permanent retaining wall with a professional stone aesthetic.Each panel is cast from Glass Fiber Reinforced Concrete (GFRC) and achieves approximately 12,000 psi compressive strength. Unlike timber that rots, steel that rusts, or standard concrete block that spalls, GFRC panels are impervious to freeze-thaw cycles, UV degradation, and moisture intrusion. Maintenance-free for 50+ years.How It WorksPanels slide vertically into the channels of installed GFRC posts, stacking from the ground up to your desired wall height. No mortar, no adhesive, no fasteners. Each panel locks in place by gravity and the post channel geometry. Add or remove panels as needed for future adjustments.Available Finishes Corten Steel — Industrial weathered-steel look that will never rust or stain your patio surfaces Limestone — Classical quarried limestone texture, timeless and versatile Stacked Stone — Traditional mortared stack-stone pattern, works with any home style Brick Veneer — Classic red brick running bond with smooth posts, caps, and sill for a refined look Specifications Dimensions: 48" × 25" × 1" Weight: 64 lbs per panel Material: GFRC (Glass Fiber Reinforced Concrete) Finish: Sealed high-strength concrete Country of Origin: USA How Shipped: Pallet Ordering guidance: For a standard wall run, panels are spaced between posts set at 48" on center. Each panel covers one 4-foot section. Count your linear feet, divide by 4, and that's your panel quantity. Corner posts require one panel per exposed face.
