What does pre-construction treatment cover?
Termites reach buildings through the soil. They build their colonies below the surface and then work their way through backfill, sand and gravel until they find the timber and organic materials inside the structure. Once the concrete is poured and the floors are finished, reaching those layers becomes very difficult and the soil beneath stays untreated.
Call or message us on WhatsApp at any stage of construction before the foundations, backfill or floor slabs are poured, tell us your district and the current stage of the build, and we agree a time with you.
The treatment goes through these layers and surfaces in sequence, depending on which stage the build has reached when you call.
- Base excavation and natural soil
The soil layer at the base of the excavation is treated before any construction work, because termites start moving from this level upward through the structure.
- Foundation walls and sides
The sides of the foundations are treated before backfill is placed against them, as this zone is hidden after finishing and forms a direct path from the soil into the building.
- Backfill and sand layers
Each layer of backfill added on top of the treated soil needs treating in turn, because termites move between layers and do not stop at one treated band.
- Under-slab and basement zones
The surface directly beneath the floor slab is treated just before the concrete is poured, as that is the last chance to reach this zone before it is sealed.
- External perimeter of the building
A band of soil along the full outer perimeter of the building is treated to close off termite entry points from the sides, not only from below.
- Service ducts and pipe penetrations
The points where drain pipes and cable ducts pass through the slab are small gaps that insects use later and need treating before they are sealed.

Tell us the build stage
Tell us whether the project is at excavation, foundations, backfill or pre-slab stage, and where it is, and we agree what is needed.

We agree a time and you prepare
We settle on a time that fits the contractor's schedule, and it helps to let the construction crew know in advance so the target zone stays uncovered.

Treatment and what to check after
The agreed layers are treated in sequence, and it is advisable to wait until the treatment is complete before continuing with backfill or pouring concrete on top.

Questions about Pre-construction termite treatment
Can the soil be treated after the foundations are poured but before the backfill?
Yes, and this is one of the most important intervention stages because the sides of the foundations are still exposed. The soil touching the foundations and their sides can be treated before backfill is placed on top, which closes a main path from the soil into the building.
What should I prepare at the building site before treatment?
Tell the contractor the time in advance so the target zone stays clear of building materials. The cleaner the layer to be treated is from large gravel and rubble, the easier and more thorough the access will be.
When exactly should I ask for pre-construction treatment, and is it too late if backfill has started?
Treatment can be requested at any stage before the final slab over the soil is poured. If backfill has partly started, the upper layers and exposed sides can still be treated. The situation that calls for a different approach is when concrete and finishing are fully complete, and that is discussed when you call.
Do I need to notify or get approval from the contractor before treatment?
Telling the contractor the time is a practical step, not a formal requirement, and the purpose is simply to make sure the crew does not complete backfill or pouring before treatment finishes. We ask about the site details when you call and agree a time that works for everyone.
Does treatment differ between a villa and a residential block at this stage?
The principle is the same, but the footprint, the depth of the excavation and the number of floors affect the scope and the number of layers that need treating. That is why we ask about the building type and its dimensions when you call, so we agree on what suits your specific site.
