Core excavation calculators
Start here for bank volume, trench volume, foundation excavations, cut/fill balance, and itemized earthwork pricing.
Excavation Volume Calculator
Estimate rectangular, trench, or slope-sided excavation volume and convert bank volume to loose spoil with soil swell factors.
Trench Volume Calculator
Calculate utility, footing, or drainage trench volume with rectangular or trapezoidal cross-sections.
Foundation Excavation Calculator
Plan slab, crawlspace, or basement dig volume with working room and optional strip footing excavation.
Cut and Fill Calculator
Compare cut volume and fill demand so grading work can balance onsite material before hauling or importing soil.
Excavation Cost Calculator
Build an excavation estimate for digging, hauling, disposal, labor, equipment, and markup.
Material quantity calculators
Convert earthwork volumes into reusable fill, imported material, weight, and density-based quantities.
Backfill Calculator
Estimate backfill volume, compaction allowance, material weight, and truckloads for trenches, foundations, and walls.
Soil Swell and Shrink Calculator
Convert between bank, loose, and compacted soil states with material-specific swell and shrink factors.
Cubic Meters to Tonnes Calculator
Convert soil, sand, gravel, concrete, and other material volumes to tonnes using density.
Topsoil Removal Calculator
Estimate stripping volume, weight, and truckloads before grading, site prep, or foundation work.
Gravel Calculator
Calculate gravel volume and weight for drainage layers, working pads, access roads, and fill zones.
Hauling and spoil planning
Size dump truck loads, stockpile footprints, and haul-away quantities from loose excavation spoil.
Dump Truck Load Calculator
Estimate dump truck trips with both bed capacity and payload limits for soil, gravel, rock, and debris.
Spoil Pile Calculator
Plan loose spoil pile footprint, pile height, slope angle, and setback needs around an excavation.
Dump Truck Sizes for Excavation Hauling
Compare typical dump truck cubic yard capacity, payload limits, and the difference between volume-limited and weight-limited hauling.
Spoil Pile Planning Guide
Learn how to stage excavated material while preserving access, drainage, trench edge setbacks, and site safety.
Trench and safety planning
Check trench slope geometry, OSHA safety concepts, soil behavior, and practical planning limits before digging.
Trench Sloping Calculator
Calculate OSHA-style trench slope or bench dimensions from soil type, depth, and excavation geometry.
OSHA Trench Safety Requirements
Review trench protective systems, soil classification, access, inspections, and common depth thresholds.
Soil Types for Excavation Planning
Compare soil types by density, swell, shrink, moisture sensitivity, sloughing tendency, and reuse as fill.
How to Estimate Trench Excavation Volume
Walk through trench width, depth, length, slope allowances, bank volume, loose spoil, and hauling estimates.
Excavation guides
Use these guides when you need reference tables, material selection help, or a full earthwork workflow.
Excavation and Earthworks Guide
Overview of the excavation calculator set with workflows for volume, soil state, hauling, cost, and safety planning.
Backfill Material Guide
Choose native soil, structural fill, sand, gravel, crushed stone, bedding, or drainage material for backfill.
Understanding Soil Swell and Shrink Factors
Understand why bank excavation volume, loose spoil volume, and compacted fill volume are not the same.
Gravel Density Chart
Reference gravel, stone, sand, soil, and backfill densities for hauling, ordering, and volume-to-weight conversion.
