Why TrenchCalc

Use TrenchCalc for dayworks, project planning, on-site verification, material ordering, and compliance documentation. Calculate trench volumes and get material estimates on-site, without returning to the office.

Trench Volume Calculator

Trench Volume Calculator

Real trenches aren't simple rectangles. TrenchCalc performs multi-zone calculations with vertical, battered, and benched walls. Calculate foundation, bed, haunch, side fill, and overlay volumes separately — with culvert obstructions accounted for.

Cement Stabilization

Calculate UCS (Unconfined Compressive Strength) estimates for cement-stabilized materials. View 7-day and 28-day strength estimates.

Cement Stabilization
LiDAR Scanning

LiDAR Scanning

Measure trenches and stockpiles using your iPhone's LiDAR sensor — an alternative to tape measures. Scan various geometries and calculate volumes from 3D data.

What Sets TrenchCalc Apart

Multi-Zone: 7 distinct zones with different materials, geometries, and cement stabilization per zone
Field-Ready: On-site input, visual aids, and feedback built-in
Intelligent Validation: Real-time fit warnings and safety breach detection
AI-Powered Documentation: Voice-to-text diary with AI polishing
Integrated Workflow: 12 tabs working together with customizable interface
