Expert Termite Barriers That Work
The single biggest area where termite treatments fail, is when drilling and injecting through concrete has taken place. It is always our recommendation that a treatment strip be cut into all concrete areas along the perimeter of the house. This allows the soil replacement technique to be used, that is, where the soil below the concrete areas can be excavated and replaced with a clean soil or loam mix. This method of treatment ensues two things. Firstly, the treatment or chemical barrier has a longer life expectancy (that is, what the manufacturer has deemed as the life expectancy of their chemical product). Secondly, it creates a complex barrier around the property.
Where this method of treatment is declined by the customer (and drilling is requested), then the limitations and limited life expectancy of this method of treatment must be accepted by the customer.
