Pre Construction Termite Treatment
Pre-construction termite treatment is a critical process in the building industry aimed at protecting structures from the devastating effects of termite infestations. This preventative measure involves treating the soil and building materials with termiticides before the construction begins. By implementing these treatments, builders can ensure that the foundation of the building remains secure and free from termite damage. Termite is a major pest of properties, and the potential for termite infestation is huge due to growing urbanization and construction activities.

How To Find Termites?
Finding termites can be challenging, as they often hide inside wood or soil. However, there are some signs that can indicate their presence, such as
- Hollow or damaged wood. You can use a screwdriver or a similar tool to probe the wood and check for hollow spots or tunnels.
- Termite swarms. These are winged termites that emerge from their nests to mate and start new colonies. They usually swarm in spring or summer and are attracted to light sources. They may shed their wings after swarming, leaving piles of wings behind.
- Mud tubes. These are thin tubes made of soil and termite saliva that termites use to travel between their nests and food sources. They are often found on walls, foundations, or other structures.
- These are small pellets of wood that termites excrete. They may look like sawdust or coffee grounds and are usually found near termite-infested wood.
- If you suspect you have termites, you should contact a professional pest control service to inspect and treat your property.

Pre-Construction Anti-Termite Treatment
Treatment of soil below the raft
The blue mark represents the Premise treated area Treatment for buildings with a basement starts after the excavation for the basement is complete and before laying soling and Plinth Cement Concrete Before laying the rubble soling and Plinth Cement
Treatment of soil along the retaining walls
The soil retained by the walls (soil coming in contact with the retaining wall) shall be treated at the rate of 7.5 lit./m? of the vertical surface so as to affect a continuous outer chemical barrier, in continuation with that of the one formed below the raft.
The treatment shall follow the backfilling as backfilling is done in stages of 30 cm but not to exceed a depth of 1 meter. Rodding may be carried out to facilitate the treatment
Treatment of soil Surrounding Pipes, Wastes, and Conduits
When pipes, wastes, and conduits enter the soil inside the area of the foundations, the soil surrounding the point of entry shall be loosened around each such pipe, waste, or conduit for a distance of 150 mm and to a depth of 75 mm before treatment is commenced. When they enter the soil external to the foundation, they shall be similarly treated at a distance of over 300 mm unless they stand clear of the walls of the building by about 75 mm. Chemical emulsion to be poured at the rate of 7.5 lit./m2 of vertical surface
Treatment of soil Along the External Perimeter of the Building
Treatment of Soil Along the External Perimeter of the Building After the building is complete, the earth along the external perimeter of the building should be rodded at intervals of 150 mm and to a depth of 300 mm. The rods should be moved backward and forward parallel to the wall to break up the earth. The chemical emulsion should be poured along the wall at the rate of 7.5 lit./m? of the vertical surface. In the event of filling being more than 300 mm, the external perimeter treatment shall extend to the full depth of filling up to the ground level so as to ensure the continuity of the chemical barrier.
