Underslab Sheet Waterproofing with Non-Pesticide Termite Barrier | ||||||||||||||||||||||||||||||||||||||||||||||||||
This section is based on the products ofTERM Waterproofing and Termite Barriers, which is located at: 01 South Interstate 45 Highway Ennis, TX 75119 Phone: 214-515-5000 Fax: 972-875-9425 Email: info@polyguardproducts.com Web: http://www.polyguardproducts.com/term [Click Here] for additional information. Polyguard's history began with corrosion protective coatings in 1951, In 1970 structural waterproofing was added. Now we add TERM non-chemical termite barrier which is integrated into waterproofing. This results from 20+ years of work with entomology scientists. Water and termites 'leak' into the structure through the building envelope. Around most of the envelope, both types of leaks can now be stopped. Concrete floors and walls have joints; through which water and termites enter. Concrete slabs crack, creating new entry points. It cannot be predicted where cracks will appear in the slab, so full protection should include 100% underslab and foundation wall coverage with TERMŽ Barriers. The objective is first to block water, and second to block termites trying to find gaps as small as 1/50th of an inch. Since keeping termites out means keeping virtually all other insects out, you will see a variety of health, comfort, and environmental benefits. Above the slab, TERM Sill Barrier is installed and tied into flashing at the base of the exterior sheathing, providing protection from moisture, termite, and air leaks. Several non-waterproofing TERM barriers, which protect against termites at points of drainage, ventilation, and exposed perimeters, are also part of the TERM System. These protect areas where TERM Barrier waterproofing cannot be installed. | ||||||||||||||||||||||||||||||||||||||||||||||||||
