The first and the most important part is the site preparation. The removal of trees, stumps, roots etc. from the site reduces the chances of an attack by the termites.
The sides and bottom surfaces of the foundation trenches and pits are treated with chemicals.
The backfilled soil of the built up wall is treated. The chemicals are directed towards the masonry surfaces so that the earth in contact with such surfaces is well treated with chemicals.
The top surface of consolidated earth within support walls is treated with chemical emulsions.
The treatment of wall and floor junctions is done to ensure continuity in the vertical chemical barrier.
The earth on the external perimeter of the building will also be treated to ensure maximum protection.
