A: Refer to this page for more information to help with estimating the cost.
“How much does it cost” is a really tough question. Let’s start with a generalization, and then go to some specific areas:
TERM was designed with the concept that the termite barrier should be integrated with waterproofing materials already in use. Polyguard produces a wide range of building envelope materials which seal out water, and seal off energy leaks. The goal, which is now achieved, is to use the same materials to also seal out termites from the structure.
Having achieved that goal, we can state that, wherever the building envelope uses the widely accepted “peel and stick” materials using asphalt modified polymers are being used – in other words the type of waterproofing which Polyguard has been supplying, the addition of TERM Barriers to the project should only cause a slight to moderate increase in project cost.
Having said that, there could be a significant increase in cost of protection underneath the slab. Underslab vapor barriers are inexpensive to buy and they install fast and easily. However, in higher end projects, full underslab waterproofing is being adopted. This is because the severe abuse of concrete slab construction puts thousands of punctures in vapor barriers, which reduces their effectiveness. The punctures may each be small – but they are big enough for termites to get through. (Also remember that termites chew through plastic)
Anyway, if you are one of those who has already moved to full underslab waterproofing, the incremental cost of TERM Underslab Barrier should be moderate.
Comments on the most significant TERM commercial applications are below.
