What it does
SlabMate is a fast concrete calculator for tradespeople, landscapers, groundworkers, handymen, and practical DIY users who need clear material estimates. Enter dimensions for a slab, shed base, path, post hole, pad, footing, or simple pour and SlabMate calculates volume, litres, bag count, waste, estimated weight, cost, and material breakdown. A lightweight isometric preview helps spot obvious dimension mistakes before ordering or mixing. The calculator is free and works offline.
