Termite reticulation system
A termite reticulation system is perforated pipes under the slab perimeter, letting termiticide be re-injected from outside when chemical life expires. No trenching.
Ask Chalkline about this →A termite reticulation system is a network of perforated pipes installed around the slab perimeter before the pour through which a soil termiticide can be re-injected from outside the building when the chemical’s protection period expires. It is the alternative to re-trenching every 8 to 10 years to refresh the chemical barrier. Used with non-repellent termite actives, most commonly fipronil or imidacloprid, where the transfer-effect protection depends on a fresh chemical zone.
Why builders fit one
Chemical barriers have a finite life: bifenthrin about 10 years, fipronil about 8. After that the owner faces three choices:
- Re-trench and re-treat. Expensive, disruptive, often blocked by post-build landscaping.
- Switch to a physical barrier. Major work.
- Pre-installed reticulation. Pest tech recharges through the existing inlets. No digging.
The reticulation pays for itself the first time it’s recharged 10 to 15 years later.
Install
- Perforated PE or PVC pipes in the slab perimeter footing trench, before pour.
- Inlet manifolds brought up at external corners and door thresholds.
- Certified design by a pest tech under AS 3660.1.
For a builder
- Book the pest installer into the slab program early. Pipes go in pre-pour; missed window = re-trench at recharge.
- Mark and protect the inlets. Note on the durable notice and as-built.
- Cost it as a premium. Add now, save much more at recharge.
