Pre-Construction Termite Treatment South Africa, often called soil poisoning, is a termiticide treatment applied to the ground before the floor slab and foundations are covered. It is booked by owner-builders, contractors and developers to protect new buildings and extensions against subterranean termites.
- Have the plan or footprint size (m²) and the foundation layout ready.
- Give the planned date for casting the slab.
- Say whether you need a treatment certificate for an inspector, bank or buyer.

- Foundation trenches. Trenches are treated after excavation and before concrete or brickwork goes in.
- Under the slab. The compacted fill is treated after levelling and before the damp-proof membrane and slab are placed.
- Around the perimeter. Some providers treat the outer edge later, before paving or backfill.
- Certificate. The provider records the area, product and date and issues documentation.
Timing is the critical part. If the slab is cast before the treatment, the opportunity is gone and only post-construction methods remain.
Coordinating Soil Treatment With Your Builder
- Agree who books the provider: you, the builder or the site manager.
- Give the provider at least a few days' notice before each stage.
- Keep the area dry and undisturbed after treatment until the membrane and slab go down.
- Ask whether the provider needs to return for extensions, paving or a second phase.
Site Inspection and Documentation
Before quoting, a provider may visit or work from the plans to confirm the footprint, trench lengths and access. After treatment, ask for written documentation showing the property, date, treated area and product used, and any guarantee period the provider offers, in writing.
Is Pre-Construction Termite Treatment Required?
The SANS 10400 building regulations include requirements for protecting buildings against termites in areas where termites are a risk. How this is applied varies between municipalities, and banks or inspectors may ask for a certificate. Check with your local building control office or your architect. It is not compulsory everywhere in South Africa.

Ballpark figures, not quotations. Ranges compiled from price guides published by South African pest-control and quote websites, checked 20 October 2026 and rounded where needed. They are not our prices and no provider is bound by them. Minimum charges, return visits for each stage and certificate fees vary by provider, so ask for them in writing. Published guides vary widely, so treat the ranges as a sanity check only. Most sources do not state whether VAT is included, so confirm VAT on every quote.

After the Slab: Ongoing Termite Protection
- Keep the paperwork with the building plans for future sales.
- Avoid breaking the treated zone with later digging unless it is re-treated.
- Keep soil and mulch below the damp-proof course.
- Have any later activity inspected under termite control.
Treatment for Homes, Extensions and Developments
Single homes and extensions need one or two visits. Townhouse complexes, schools and commercial buildings need treatment scheduled across phases, often coordinated through the main contractor.

Pre-Construction Termite Treatment FAQs
Can soil treatment be done after the slab is cast?
Not in the same way. Once the slab is down, protection relies on drilling through the floor or treating around the perimeter, which is a post-construction termite treatment.
Does an extension need its own treatment?
Usually yes. The new footprint has not been treated, so it needs its own soil treatment before its slab is cast. Check with your building control office.
Who should pay for pre-construction treatment, the builder or the owner?
It depends on the building contract. Check whether it is included in the builder's price or listed as the owner's responsibility.
What paperwork should I get?
Written documentation with the address, date, treated area and product, plus any guarantee terms. Keep it with your plans and occupation documents.
How long does pre-construction treatment last?
It depends on the product, soil and later disturbance. Ask each provider what period their documentation or guarantee covers.
