Ascenol

Plan your paving project with confidence before you lift a single slab. Ascenol calculates exactly how many block pavers, slabs, or setts your area needs, maps every cut, and guides you through the job from first string line to last joint — all from your phone. Draw your area using ready-made templates for patios, paths, driveways, shed bases, and L-shapes, then add cut-outs for trees, posts, or drains. Pick from eight real-world paving units — from a classic 200x100 block paver to a 900x150 porcelain plank — choose your bond pattern, and Ascenol tiles the whole area instantly. Every piece is colour-coded: full units, straight cuts, corner cuts, notches, and slivers. The Best Start engine searches all valid bond offsets and finds the starting position that minimises your total cuts and waste. Tap any piece on the live plan to see the exact cutting instruction and track how its offcut is reused downstream. The Cuts tab lets you tick off each saw cut as you make it. A complete materials list — pavers, sub-base, bedding sand, jointing sand, and edge restraint — is computed for your exact shape, with configurable waste allowance, pack rounding, and optional cost totals. When you are ready, export a high-resolution plan sheet to share with your supplier or keep on file for the job. Ascenol works entirely offline. No account required, no subscription, and nothing leaves your device.
