It’s a network of micro-perforated pipes (usually 12mm–16mm) laid in a loop/grid pattern under your floor slab before flooring is finished — covering both the perimeter and the center of the floor for full coverage. Termiticide is injected through the network so it reaches every key termite entry point, creating a continuous underground chemical barrier.
Unlike older soil treatment methods — where re-treatment means drilling into your finished tiles or marble — a piping system is replenishable from outside the building. No drilling, no moved furniture, no smell indoors.
