The system is consisted of network of Chemical resistant, Polyethylene (LLDPE) tubes with ‘Pressure compensated’ chemical emitters on the tube at a constant spacing. These fluid emitters discharge anti termite chemicals in to soil, making a uniform chemical barrier against the termite access points. The tubes are laid beneath the ground floor slab along the vulnerable construction joints, expansion gaps, outer perimeter and inner perimeter of the entire building. Other vulnerable openings are also covered with a branch network. The recharging inlets are placed in a suitable area for easy recharge. The system is recommended to be recharged every 4-5 years to sustain the chemical efficacy levels and to maintain the protection against soil termites throughout the economic life of the building. The Piperguard, chemical recharging system is a proprietary product of John Piper International (Pvt) Ltd. (Patent No. 15141 Sri Lanka). This system is the most realistic and environmental friendly alternative after total ban of long lasting Organo- Chlorine Termiticides such as DDT, Aldrin and Dialdrin. Offering 10 year warranty for a short life chemical such as a Bifenthrin is far from reality as its efficacy remains maximum for about five years under tropical environmental conditions. (Please refer the facts sheets of the Bifenthrin (page 7)(http://cpmservices.com.au/Label/Label%20-%20Biflex%20Ultra%20LoOdour.pdf )and other pesticides).
