Pre Construction Soil Treatment

Post construction treatment is recommended for the buildings where floor concrete is laid without applying Termiticide. The only way to apply the Termiticides is by injecting the Termiticide to the soil under the floor slab through a set of drilled holes on floor, closer to foundation footings (Wall-floor Junction area). This chemical will be dispersed under the floor slab and make barrier for termites. The uniformity of the chemical barrier cannot be determined and therefore there is a risk of re-infestation compared to pre construction soil treatment in this process your floor has to be drilled approximately 1.5 feet apart near the walls where necessary.
This process is relatively more expensive than pre construction treatment since it consumes much time and chemicals. But is only remedy for this kind of situation.
