Subterranean termites inhabit native sandy soils across Jubail. When construction activities disturb the ground, workers often inadvertently bury timber formwork scraps, creating immediate food sources that attract termite colonies straight to foundation footings.
Pre-Construction Prevention Checklist:
- Site Debris Removal: Ensure all wooden formwork stakes, wood chips, paper cement bags, and organic roots are completely cleared from sub-grade soil before chemical application.
- Horizontal Soil Barrier: Apply approved termiticide uniformly across the entire graded sub-base soil prior to laying vapor-barrier polyethylene sheets and pouring concrete slabs.
- Vertical Trench Barrier: Excavate narrow perimeter trenches around building foundation beams and retaining walls, treating the soil as it is backfilled to form an unbroken chemical shield.
- Utility Penetration Sealing: Treat soil surrounding plumbing sleeves and electrical conduit penetrations, which provide direct upward pathways for foraging termites.
