Pre-Construction Anti-Termite Treatment: What Builders and Homeowners Should Know
Pre-construction anti-termite treatment protects a new building from below, before the floor and foundation are sealed off. This guide explains when it is done, why timing matters, and what to ask your contractor.
Most termite problems in buildings start in the soil. Termites travel up from the ground through gaps in the foundation and floor, so the best time to stop them is before that ground is covered by concrete.
Pre-construction anti-termite treatment does exactly that. The soil is treated while the foundation is still open, so a protective layer sits under and around the building once it is finished.
This guide is only about new construction. If you already live in a building and are seeing signs of termites, our termite guide and after-construction treatment page are the right places to start.
Why it matters for new buildings
- Once the floor slab is cast, the soil underneath cannot be reached again in the same way. Treatment has to happen at the right stage or the chance is lost.
- Fixing termites in a finished building is usually harder and more disruptive than treating the soil during construction.
- Our pre-construction service follows the IS 6313 Indian Standard for anti-termite treatment and includes a treatment certificate.
- Building approvals in Maharashtra commonly ask for an anti-termite treatment certificate, so it is worth planning for early.
When pre-construction treatment is done
Treatment is done in stages as the building goes up, not in a single visit. The main stages are before the PCC (plain cement concrete) is laid, before the floor slab is cast, and on the perimeter walls during backfilling. Because each stage depends on the construction schedule, the treatment team needs to work with the site engineer so they are called at the right time.
What the treatment covers
The aim is to treat every point where the building meets the soil. That includes the soil surface before the slab is poured, foundation walls, column pits and the area around the structure. Missing one of these points leaves a gap termites can use later.
Questions to ask your contractor
Ask who is doing the anti-termite treatment and whether it follows IS 6313. Ask at which construction stages they will treat, and how they will be informed before each stage begins. Ask whether you will receive a treatment certificate and what details it will show. Ask what happens if a stage is missed or the schedule changes. Finally, keep the certificate with your building papers so you have a record if you need it later.
Pre-construction vs after-construction treatment
Pre-construction treatment is planned into building work and treats the soil before it is covered. After-construction (post-termite) treatment is for buildings that are already standing, where the team has to reach the soil by other means. For renovations where the structure is opened up, pre-construction methods may still be possible; if the structure is intact, after-construction treatment is used.

Pre-Construction Termite Treatment: frequently asked questions
When should pre-construction anti-termite treatment be done?
In stages during building work: before the PCC is laid, before the floor slab is cast, and on the perimeter walls during backfilling.
Can it be done after the building is finished?
Not in the same way. Once the slab is cast the soil underneath is covered, so finished buildings need after-construction (post-termite) treatment instead.
Will I get a certificate?
Yes. Our pre-construction service includes a treatment certificate, which is commonly needed for building approvals in Maharashtra.
Which standard should the treatment follow?
Ask for treatment that follows IS 6313, the Indian Standard for anti-termite treatment of buildings.
How much does it cost?
It depends on the building size, foundation type and soil area. An estimate is given after a site visit.
