Request a QuoteProject Considerations in Wellington
- Soil report first. Ground conditions vary from plot to plot in Wellington. A geotechnical investigation tells the engineer whether a raft is the right foundation.
- Winter rain. Most rain falls in winter. Trenches can flood and pours move to dry days, so allow extra time from about May to August.
- Summer heat. Hot, dry summer days dry slab surfaces quickly. Ask when the contractor will pour and how they will cure the concrete.
- Extensions to older homes. A new raft next to an existing house has to work with the old foundations. Ask the engineer how the two will be joined.
Approvals
- Building plans. Plans for new buildings and extensions in Wellington are submitted to Drakenstein Municipality for approval.
- Engineer. A registered engineer designs the raft, inspects the steel and signs off the work.
- NHBRC. New homes must be enrolled with the NHBRC before construction starts.
- Heritage. Buildings older than 60 years and properties in heritage areas may need heritage approval for alterations.
What the Work Includes
- Groundwork. Clearing, levelling, compaction and trenching for ground beams.
- Damp-proofing. Sand blinding, DPM and termite treatment where specified.
- Steel. Mesh and beam reinforcement fixed to the engineer's drawings.
- Concrete. Ready-mix pour, finishing and curing.

Plans for new buildings and extensions in Wellington are submitted to Drakenstein Municipality for approval. The engineer's raft design forms part of the submission.
Is a raft foundation always needed in Wellington?
