Termite Control

1. SCOPE
This standard (Part 2) gives recommendations for the chemical treatment of soils for the protection of buildings from attack by subterranean termites. It includes reference to the chemicals to be used, lays down minimum rates of application for usage, and outlines procedures to be followed while the building is under construction.

2. REFERENCES
The Indian Standards given in Annex B contain provisions, which through reference in this text, constitute provision of this standard. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this standard are encouraged to investigate the possibility of applying the most recent editions of@e s@dm,ds indicated.

3. TERMINOLOGY
For the purpose of this standard, the following definitions shall apply.
3.1 Chemical Barrier The layer of chemically treated soil in immediate contact with the foundation and floor structure of a building which kills or repels termites thus forming a barrier which is impervious to termite entry.
3.2 Soil Treatment The application of chemicals (toxicants) to the soil adjacent to and under a building to form a chemical barrier which is lethal or repellent to termites. 3.3 Pre-Construction Soil Treatment This is a process in which soil treatment is applied to a buildlng during the early stages of its construction.

4. SITE PREPARATION
4.1 The removal of trees, stumps, logs or roots from a building site reduces the hazards from subterranean termites. Similarly, the sub floor area should be kept free from all debris in which new colonies of termites might be established. In order to ensure uniform distribution of the treating solution and to assist penetration, some site preparation, may be necessary. The information given in 4.1.1 to 4.1.4 is for guidance in preparing a building site for chemical treatment.
4.LI Heavy Soils and Sloping Sites On clay and other heavy soils where penetration is likely to be slow and on sloping sites where run off of the treating solution is likely to occur, the surface of the soil should be scarified to a depth of at least 75 mm.
4.1.2 Sandy or Porous Soils On loose, sandy or porous soils where loss of treating solution through piping or excessive percolation is likely to occur, preliminary moistening to fill the capillary spaces in the soil is recommended.
4.1.3 Levelling, Excavations and Filling All sub floor levelling and grading should be completed; all cuttings, trenches and excavations should be completed with backfilling in place, borrowed fill must be free from organic debris and should be well compacted. If this is not done supplementary treatments should be made to complete the barrier.
4.L4 Concrete Formwork All concrete formwork, Ievelling pegs, timber off-cuts and other builder’s debris should be removed from the area to be treated.

5. CHEMICALS AND RATE OF APPLICATION
5.1 Basic Principle Chemical toxic to subterranean termites maybe used effectively to check termite infestation in the soil. These are useful in the treatment of new building sites and may also be used to eradicate existing infestation in buildings and to prevent reinfestation. The effectiveness and/or residual activity depend upon the choice of the chemicals, the dosages adopted and the thoroughness of application. The chemical solutions or emulsions are required to be dispersed uniformly in the soil and of the required strength so as to form an effective chemical barrier which is lethal and repellent to termites.

Ensuring Long-Lasting Protection from the Ground Up

Our Pre-Construction Termite Control Services provide essential protection for new buildings, preventing termite infestations from the outset. By treating the soil and foundation areas before construction begins, we create a barrier that deters termites and protects the structural integrity of your property. Our advanced and eco-friendly treatments ensure long-lasting defense, giving you peace of mind that your investment is safeguarded from termite damage right from the start.
