• Proven Protection – Effective against both Formosan and native subterranean termite species, with 100% efficacy when properly installed
• Non-Chemical Solution – Pesticide-free and safe for children, pets, and the environment
• Durable Quartz Particulates – Precisely sized (8–16 mesh), angular/sub-angular stones are too small for termites to pass through, too heavy to be moved, and too hard to chew
• LEED-Eligible – Recognized by the Green Building Certification Institute for nontoxic pest control credits
• Reduces Termiticide Use – Minimizes reliance on chemical treatments over the life of the structure
• Versatile Applications – Effective around exposed vertical slabs, bath traps, piers, and other concrete leave-outs
• Long History of Success – Technology developed in Hawaii, Australia, and the Pacific Rim since the 1950s

• Material: Angular / Sub-angular quartz particulates
• Mesh Size: 8–16 (field-proven for termite exclusion)
• Fineness Modulus: 3.83
• Mohs Hardness: > 6
• Void Space: 1.72% (calculated via water displacement)
• % Retained on Sieve (8–14): ≥ 90% (ASTM D451)
• Packaging: 50 lb Bag (Part Number: TERMPART50TX)

Common Substrates / Installation Areas:

• Concrete Perimeters & Foundations – Installed in a wedge-shaped trench (min. 4" wide x 5" deep) along exposed vertical concrete
• Bath Traps / Leave-Outs – Can be poured into open traps before slab pour or combined with TRM Micromesh for “belt and suspenders” protection
• Concrete Piers & Slabs – Fills gaps or leave-outs to eliminate subterranean termite entry points
• Brownfield / Contaminated Sites – May qualify for LEED credits as a below-grade toxin barrier

Installation Guidelines:

1. Excavate a trench or leave-out at vulnerable points
2. Clean vertical surfaces of mud and debris
3. Fill trench/void with TRM Particle Barrier to grade level
4. Compact as needed to eliminate gaps
5. Inspect annually and maintain barrier integrity; refill if voids/disruptions occur

Maintenance: Must be visually inspected regularly. Licensed pest management professionals should assess and repair as needed.
