Termite physical barriers have a visual inspection zone that should be exposed for ongoing inspections, especially on the perimeter of a brick veneer home like the one in the video below. It is critical to ensure the barrier is exposed above ground level to ensure visual termite inspections can be carried out by an expert and regularly by the owner.
Covering a physical barrier inspection zone with anything will render the barrier ineffective. If you cannot inspect the inspection zone (being the product line that protrudes to the outer edge of the home, usually the perimeter), it is most likely you will get termites attacking your home.
A physical barrier is designed to prevent concealed entry only; the barrier is designed to force the termites out in the open so that you can see them. Covering the perimeter physical barrier in a brick veneer home like this video below is asking for trouble.
The system installed in this video appears adequate; the only reason it will not work is the homeowner not keeping the inspection zone clear by removing soil and pavers and items like stored goods and the electrical box, garden shed in this instance.
