How the Estimating Engine Works
Input your raw site dimensions and instantly receive a verified PDF breakdown to hand directly to your aggregate supplier.
Enter Site Dimensions
Enter exactly what is on your drawing: trench depth profiles, pipe outside diameters (OD), or circular pit geometry. No need to manually calculate total volumes first.
Apply UK Standards
The DigFill engine automatically cross-references structural displacement formulas, aggregate compaction modifiers, and specific soil swell percentages for your muck away.
Export to Site Log
Every calculation yields precise Type 1 MOT tonnages and 16T grab lorry schedules. Values are saved immediately to your active Site Log archive to share with your foremen.
The Core Calculators
One Pro membership unlocks the complete suite of UK groundworks and drainage tools.
Trench Builder
Calculate layer-by-layer pea shingle bedding, native pipe surrounds, and Type 1 MOT backfill weights. Automatically deducts pipe volume via OD displacement.
Open Trench Module →Manhole Logic
Calculate exact backfill aggregates surrounding precast concrete chambers. Automatically factors in ring wall displacement, working space, and ironwork build-ups.
Open Manhole Module →Muck Away Logistics
Integrated directly into our calculators. Converts solid trench dimensions into loose spoil using native soil swell factors, outputting exact 16T grab lorry counts.
See Logistics Engine →Calibrated to British Standards
Every tool output cross-references published UK specifications, replacing site guesswork with unquestionable mathematical logic.

Software FAQ
What is groundworks estimating software?
Groundworks estimating software, like DigFill, automates the complex mathematics required on UK construction sites. It calculates exact aggregate tonnages (like Type 1 MOT or pea shingle), accounts for soil swell factors for muck away lorries, and processes pipe displacement without the need for error-prone manual spreadsheets.
Does DigFill calculate pipe displacement?
Yes. DigFill's trench module automatically subtracts the physical volume of your drainage pipe (using the Outside Diameter) from the surrounding backfill layers. This prevents you from over-ordering expensive aggregate on long drainage runs.
