Post Tension slabs are the way to go if you want to avoid cracks and settling of your home. Its also conducive to preventing termite activity as there are generally only the outside foundation to worry about. These slabs are often used in bridges, elevated slabs, walls, and columns. Usually you will see rebar which helps to strengthen the concrete. More and more homes are being built with this feature.
Of course there are always exceptions to every situation, sometimes the cable dislodges or breaks. I don’t see it very often but termites can get through the pipes entry points but generally speaking the cables should pull the concrete tighter.
Arizona has a moderate to heavy activity of termites, generally due to warm weather and this year rain. I always recommend getting a termite inspection every few years and especially if you are buying a home. Don’t take the word of anyone unless they are a licensed termite company. Some realtors and home inspectors will tell you don’t worry but use caution when you’re spending a lot of money. They always say that your home is the biggest investment you will ever make, be wise and hire a Termite Professional. Call ProBest Pest Management 480-831-9328 or 623-414-0176
