Anti Termite Treatment, Pre & Post Construction Termite

A.T.T  is the treatment given to the structure to protect it against Attack by subterranean termites, using a suitable chemical. The   chemical barrier   is a layer of soil in contact with the structure that has been suitably treated with approve chemical, so as to form an impervious barrier to kill that termites The following procedure of anti termite treatment to be done at the project site are based on IS 6313: 2001 The surface of the ground should be clean, compacted and firm. it should be free from any organic impurities. Safety goggles,  gloves  and face mask should be readily available at the site. The person conducting the anti termite treatment should be trained and should be wearing all the above safety gear during the operation. preliminary moisturing should be done when the soil is Sandy, loose and porous because the chemical solution may be lost due to percolation. The chemical treatment of the soil should start only after the foundation trenches and pi

Knapen system of drying walls

Principle of  Knapen system : A difference of 16 °C to 24 °C is required to displace the vitiation air from a building by means of a vertical air shaft. The Knapen Tube : The method of fixing the Knapen tube in the wall. it is a simple porous tube which is fixed with its mouth inclined outwards. As the tubes are porous the moisture of penetrates inside them. Due to difference of temperature the dry air enters in the tube from its top portion as indicated by arrow. This dry air evaporates the moisture and saturated air comes out from the lower portion of the tube. This circulation of air is due to perfectly natural laws, and remains continuous till there is any moisture left in the wall.
