Post Tension Slabs…
Post tension slabs are the way to go if you are trying to prevent termites from getting into your home. Its not always the absolute but with those cables tightened up, it should be better at preventing them from getting into the home – at least from the inside. Nothing will stop the termites from getting in from the outside of the foundation, except termiticides.
The picture below is from the front portion of the garage and honestly I don’t have any idea how they got there. The bad part of this termite activity are those cabinets which block the view of entry for those termites.
