A solid build starts with the right groundwork. Foundation excavation, RibRaft pad preparation and shed foundations across Christchurch and Canterbury.
From the first site cut to a prepared foundation pad.
NEXT Earthworks + Construction provides foundation earthworks in Christchurch for new homes, extensions, garages, sheds and rural buildings. We work with homeowners, builders and project teams to prepare the ground to the supplied plans and project specifications.
Depending on the job, our work includes topsoil stripping, foundation excavation, footing and pile-hole excavation, spoil removal, aggregate placement, grading and compaction. We plan access, levels and the construction sequence with your builder so the site is ready for the next trade.
Foundation excavation services
The groundwork your build needs.
01 / RIBRAFT
RibRaft foundation excavation
Site stripping, excavation and base preparation for RibRaft foundations. We prepare the footprint and working levels to the foundation plans, with aggregate placement and compaction as specified, ready for the foundation team.
02 / EXCAVATION
Foundation excavation
House cuts, slab footprints, perimeter footings and foundation trenches for residential and commercial projects. We coordinate spoil removal, site access and excavation stages around your build programme.
03 / REINFORCED PADS
Reinforced RibRaft pads
Earthworks and sub-base preparation for reinforced RibRaft pads, following the project-specific foundation design. Fill requirements, excavation depths and compaction are coordinated with your builder and engineer; reinforcing and concrete work are agreed separately.
04 / NZS 3604
3604 foundations
Excavation for foundations detailed under NZS 3604 where it applies to the project, including specified footing trenches and pile holes. Ground conditions and foundation requirements must be confirmed by the appropriate designer or engineer.
05 / SHEDS & GARAGES
Shed foundations
Pad preparation and foundation excavation for garages, workshops, farm sheds and other outbuildings. We can strip the footprint, cut and fill to the required levels, place aggregate and excavate footing or post holes to the supplied design.

A clear process
Plan the work. Prepare the ground.
01. Review the site
We review your drawings, access, levels and available ground information, then confirm the earthworks scope.
02. Excavate & remove
Strip the footprint, excavate to the specified levels and manage excess spoil and truck access.
03. Build the base
Place and compact specified aggregate, prepare the pad and complete the required footing or pile-hole excavation.
04. Coordinate the handover
Allow for the inspections and testing required by the project, and coordinate the next stage with your builder.

Foundation earthworks questions.
Tell us what you’re building and where. We’ll help define the excavation and preparation needed for your project.
Christchurch & Canterbury Foundation earthworks across Christchurch, Selwyn and Waimakariri, including Rolleston, Lincoln, Kaiapoi and Rangiora. Contact us to discuss your site.
What do you need to quote foundation excavation?
Send your site address, foundation plan, proposed levels and any engineering or geotechnical documents. It also helps to know the site access, build timing and whether spoil must be removed. We’ll confirm whether a site visit is needed before pricing.
Do you prepare RibRaft and reinforced foundation pads?
Yes. We carry out the excavation and ground preparation for RibRaft and reinforced pad projects to the supplied design and specifications. The quote will identify the earthworks included and how the work interfaces with your foundation contractor.
Can every site use an NZS 3604 foundation?
Foundation suitability depends on the building and the ground conditions. Your designer or engineer confirms whether NZS 3604 applies or a specific foundation design is required. We carry out the excavation to the approved project requirements.
How much do foundation earthworks cost?
Price depends on the footprint, excavation depth, ground conditions, access, spoil disposal, aggregate quantities and any testing or inspection requirements. A quote based on your plans and site information is more useful than a generic square-metre rate.
Do you excavate shed and garage foundations?
Yes. We prepare pads and excavate the specified foundations for sheds, garages, workshops and rural buildings, including footing trenches and post or pile holes where required by the design.
