About

Retaining Wall Planner

Features
Read full description

Retaining Wall Planner turns a wall layout into a shareable yard-order sheet for blocks, caps, base gravel, drainage gravel, fabric, drain pipe, waste buffers, and rough material cost. Enter wall size, block face dimensions, base trench, drainage width, and local prices to estimate what to buy before you call the yard or schedule delivery. The order sheet separates base counts from waste buffers so the rounded-up material list is easier to check with a supplier or crew lead. The app works offline, has no account requirement, and stays focused on small retaining wall material planning instead of broad contractor management. Important: Retaining Wall Planner is a material estimating tool, not an engineering or permit tool. Verify manufacturer instructions, site conditions, drainage needs, soil loads, and local requirements before building.
