Formed after the building's ground beams have been constructed prior to the concrete-foundation being poured. This is accomplished by applying pesticide into trenches in the soil adjacent to the said ground beams and any other structures in contact with the soil. The said pesticide will be applied to both sides of the said ground beams at a rate of 4 litres per 1 linear meter of trench the soil surface of the concrete-foundation is sprayed at an application rate of 5 litres of pesticide per square meter. The said barrier will prevent Subterranean Termites from penetrating the building through cracks and crevices on the reverse side of the foundation.

The second (2nd) stage of the treatment will be performed when the proposed building has been erected. The treatment involves application of pesticide to areas such as expansion joints of concrete slabs, near plumbing or utility entrances through concrete-foundation. The walls of the first floor of the building and any other level, which is in close proximity with the soil, will be treated with pesticide. We will also conduct spraying of pesticide on the entire roof trust, which will be performed once the said roof trust has been constructed.
