Multi-layer estimators for the jobs where one material isn’t enough — paver patios, walls, veneers, and other builds that stack base stone, bedding, and finish material on top of each other.
Cobblestone Calculator

Use Calculator →Stone Wall Calculator
Estimate the tons of stone needed to build a dry-stack or mortared stone wall.
Use Calculator →Walkway Stone Calculator
Compare walkway stone options and calculate the tons your path needs.
Use Calculator →Layered Builds Need Layered Estimates
A paver patio is really three orders: crushed base stone, bedding sand, and the pavers themselves — plus edge restraint and joint sand. Estimating them as one lump either overbuys the cheap material or underbuys the critical one. The paver base calculator splits the base and bedding layers for you with industry-standard depths.
The same logic applies to walls and veneers: structural fill, drainage stone behind the wall, and face material each get their own line. More specialty tools are joining this category — retaining wall block, gabion fill, veneer coverage, and flagstone are next.
