Anti-termite treatment applied before the levelling course
Why — act while you have leverage
Pre-construction soil treatment is a one-time opportunity. Once the PCC is poured over untreated soil, the chemical barrier cannot be recreated without drilling the finished floor.
What to look at
- A dated invoice naming the chemical and its concentration
- Treatment of trench sides as well as the base
- Photographs taken while the soil is still visibly wet
- Anti-termite treatment invoice naming chemical and concentration
Documents to ask for

How to check it yourself
The treatment is applied to the bottom and sides of the dug trenches, to the backfill, and to the plinth-filled earth before the levelling course goes down. The 2022 revision permits chlorpyrifos, imidacloprid and bifenthrin; the chemical actually used and its concentration go on the invoice.
Where this comes from: IS 6313 (Part 2):2022 — Anti-Termite Measures in Buildings, Pre-Constructional Chemical Treatment (Fourth Revision) (indian standard or building code)
