House and building cuts
Topsoil stripping, platform cuts, benching and trimming for new homes, additions, garages, commercial buildings and large sheds.
Excavation Christchurch
Make the right cut first.
Accurate excavation for site cuts, foundations, drainage, pools, retaining walls and detailed site work across Christchurch and Canterbury.
Excavation planned around the finished result.Levels, access, services, spoil, drainage and the following construction stage considered before digging begins.

Precision where the site demands it.
Excavation is not simply removing soil. The correct depth, profile, access and handover determine whether foundations, drainage, retaining and finished levels work as intended.
TBT Earthworks completes residential, rural and commercial excavation using machinery matched to the site—from controlled work around existing property through to larger cuts and complex hillside projects.
Site cutsPlatforms, benching, topsoil removal and construction levels.
FoundationsRibRaft, ring, engineered, house, garage and shed excavation.
Tight accessPlant and work methods selected for the available working room.
Clean handoverCartage, drainage, trimming and site preparation coordinated.
Excavation services
From detailed digging to major cuts.
Each job is assessed around drawings, underground services, access, soil conditions, required levels and where excavated material will go.
Foundation excavation
RibRaft, ring and engineered foundation excavation completed to the plans and prepared for the construction stage that follows.
Trenches and services
Drainage, service trenches, soakage excavation, swales and detailed water-management work coordinated with the wider site.
Retaining-wall excavation
Failed-wall removal, pole and footing excavation, benching, drainage preparation, backfill and access formation.
Pool excavation and removal
New pool excavation, old pool breakup and removal, controlled backfilling and preparation for the intended finished use.
Hillside and confined work
Staged excavation where slopes, neighbouring structures, narrow access and material movements require careful planning.
Included in the scope
Dig, move, prepare and hand over.
One coordinated scope reduces double handling and protects access for the work that follows.
Site assessmentPlans, services, access and required finish reviewed.
ExcavationBulk and detailed digging completed with suitable plant.
Spoil managementOnsite reuse, stockpiling or removal planned before work.
Imported materialFill and aggregates supplied, placed and compacted where required.
Drainage preparationSite water, subsoil drainage and finished falls considered.
Final trimmingThe excavated area left ready for the next contractor.
How excavation is planned
The finished level controls the first movement.
Getting the sequence right prevents re-excavation, lost access and unnecessary spoil movements.
01
Review plans and siteConfirm access, services, levels, ground conditions and intended construction.
02
Set the work sequencePlant, trucks, spoil and imported material organised around available space.
03
Excavate under controlCut depths, profiles and working platforms monitored as the job progresses.
04
Prepare the handoverTrim, drain, backfill or grade the work area for the next stage.
Excavation questions
What determines the job?
Access, depth, services, ground conditions, quantities and spoil disposal usually have the greatest effect on excavation cost and timing.
What excavation work do you undertake?
We undertake site cuts, foundations, drainage and service trenches, pools, retaining-wall excavation, hillside cuts and other detailed or bulk excavation.
Can excavated material remain onsite?
Sometimes. It depends on material quality, available space, finished levels and whether the soil is suitable for the proposed reuse.
Do you remove spoil?
Yes. Trucking and disposal can be included, or suitable material can be relocated and reused onsite where the project allows.
Can you work from engineered plans?
Yes. We regularly complete excavation associated with engineered foundations, retaining walls, drainage and civil site requirements.
Do you handle difficult-access sites?
Yes, subject to a site assessment. Machinery and the work sequence are selected around safe access and the space available.
