Pre installed chemical recharging system

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)(
)and other pesticides).
