How to Install a Termite Barrier Around a House

TERM® waterproofing with non-chemical termite barriers provides a superior solution to a complete termite barrier system around the house. Working together since 1999, Polyguard and entomology scientists developed TERM® Barriers: a non-pesticide, waterproofing/termite physical barrier.

TERM® Barriers prevent Subterranean, Formosan, Drywood, and Dampwood termites from entering a house through several common entry points:

  • Gaps created through the expansion and expansion of the concrete slab’s joints
  • Cracks in the concrete slabs
  • Gaps that occur around the slab penetrations during construction and by the expansion and
  • contraction of metal pipe
  • Gaps caused by the corrosion preventing plastic sleeves used around penetrations
  • Opening the bath traps and mop sinks to drain overflow water creates termite entry points
  • Foundation cracks and joints
  • Gaps at isolation joints
  • Seams and joints at the edges of sheathing material
  • Termite mud tunnels at exposed concrete perimeters
  • Windows, soffits, and roof fascia risk attack from swarming Formosan, Drywood, and Dampwood termites

Termites can significantly damage your house’s integrity and value. Protecting your real estate investment requires the application of quality termite prevention methods and prompt remediation if you discover termites.

Termite Damage

Termites cause nearly $40 billion in damage globally and destroy parts of more than 600,000 houses in the U.S., which is why termite prevention and control is critical.

Termites will warp and weaken the house and structural frame. They can also damage the inside of a home by eating anything that contains cellulose: books, cardboard, clothing, etc. Additionally, termites will attack outbuildings, wood fences, firewood piles, and any outdoor wood.

Signs of Termite Infestation

Termites often damage a house long before the owners realize they have a full-blown infestation. Signs that you have termite issues include:

  • House settling, that causes the floor to sink
  • Doors and windows not closing and opening properly
  • Bubbling behind paint and wallpaper
  • Water-like damage on the ceiling
  • Honeycomb-like denting (caused by tunneling termites) on the hardwood baseboard’s surface, door and window frames

Types of Termites

Nearly 2,800 species of termites live on the planet, but only a few cause us problems: Subterranean, Formosan, Drywood, and Dampwood termites.

Subterranean Termites

Subterranean termites represent 95 percent of the termite damage in North America. A colony of subterranean termites can include one million members, and eat up to 15 pounds of wood weekly, destroying house foundations, support beams, plastic pipes, insulation, and more.

Specific signs you have subterranean termites include:

  • The smell of mildew or mold
  • The presence of mazes within the walls
  • Mud tubes or tunnels (made from termite saliva, wood, and soil) near the foundation

Formosan Termites

A single colony of Formosan subterranean termites contains several million termites, which makes them ten times as destructive as American native termites that live in colonies of several hundred thousand.

Formosan subterranean termites infest wood and other cellulose-based goods. They enter structures where the wood touches the soil, by traveling through mud tubes from the wood to the ground, commonly entering through openings created by unsealed cracks and joints. Swarms may also infest roofs and other above-ground spaces.

Formosan termites thrive in warm and wet climates, like that found in the southeast U.S., but the risk is rapidly spreading into other areas of the country.

Signs of Formosan Termites Include:

  • Swarmers near doors, lights, and vents
  • Hollow sounding wood
  • A grain pattern in the wood, caused by feeding termites

TERM® Termite Barriers for House Construction

The TERM® Barrier Systems Division of Polyguard Products specializes in sustainable pesticide-less pest barriers. TERM® offers Termites, Energy, Radon, and Moisture prevention in a single building envelope solution. The sustainable system significantly reduces the need for pesticides during the house’s lifetime.

Polyguard offers TERM® Barriers for protecting specific parts of a house:

TERM® Underslab Water|Termite Barrier

TERM® Underslab Water|Termite Barrier

The TERM® Underslab Barrier is the base component of the TERM® Barrier System for blocking termites and water at the slab joints and cracks. It also elongates to accommodate joint and crack movement and can self-heal small punctures.

TERM® Termite Sealant

TERM® Termite Sealant

TERM® Termite Sealant applies with a smoothing tool or a caulking gun. It protects against termites and water at the TERM® membrane barriers overlaps, gaps, and penetrations. Metal and chemical-free, Term Termite Sealant can prevent termite entry by:

  • Sealing the corrosion preventing plastic sleeves on metal pipes
  • Sealing slab gaps, penetrations, and seams
  • As a part of the TERM® Full Bath Trap Barrier to prevent termites, fire ants, rodents, moles, etc. from getting under bathtubs at ground level
  • Detailing small tears and gaps found during inspection or construction on vertical or horizontal portions of the TERM® building envelope pest barrier system

TERM® All Pest Bath Trap Barrier

TERM® Termite Sealant


Polyguard’s TERM® All Pest Bath Trap Barrier combines a stainless-steel screen with 0.02-inch apertures, that is sealed with TERM® Termite Sealant. It blocks termites, fire ants, rats, mice, snakes, and moles from entering through bath traps in a concrete slab. Contractors install the non-chemical barrier after pouring the concrete slab and finishing the rough plumbing.

TERM® Foundation Barriers

TERM® Foundation Barriers

For twenty years, contractors have applied peel-and-stick, pliable TERM® Foundation Barriers to concrete or insulated concrete foundation walls to seal foundation joints and cracks to prevent water and termite intrusion. In addition, puncture-resistant TERM® Foundation Barriers minimize construction damage. It is also the only physical termite barrier with 19 years of testing and an evaluation report by the International Code Council AC380 ESR 3632.

TERM® Sill Plate Barrier

TERM® Sill Plate Barrier

The TERM® Sill Plate Barrier is an adhesive sealant that stops termites from accessing wood framing through joints in the floor or concrete cracks - significant access points for subterranean termites. It also blocks moisture from the steel sills, which reduces corrosion and protects borate-treated wood from leaching the mineral.

TERM® Flashing Moisture|Termite Barrier

TERM® Flashing Moisture|Termite Barrier

Builders can install Peel-and-Stick TERM® Flashing Moisture|Termite Barrier at the intersection of the horizontal concrete slab and exterior sheathing, a common entry point for termites found on the slab’s outside or foundation wall. TERM® Flashing Moisture|Termite Barrier also stops energy and moisture leaks at the slab and sheathing intersection.

In addition, you can use TERM® Flashing Moisture|Termite Barrier to seal sheathing seams and the gaps around door and window openings, to further protect against termite and water intrusion.

TERM® Isolation Joint Barrier

TERM® Isolation Joint Barrier

Peel-and-stick, TERM® Isolation Joint Barrier incorporates termite sealant and stainless-steel wire mesh with 0.02-inch apertures to seal isolation joints (cold joints) that happen in the gaps where patios, sidewalks, and driveways connect with the house, spaces where termites and other pests can infiltrate.

TERM® Particle Barrier

TERM® Particle Barrier

TERM® Particle Barrier protects several points on the structure from termite entry, including the exposed concrete perimeter and bath traps. TERM® Particle Barrier consists of sub-angular or angular quartz particulates with mesh sizes (number of mesh openings in one linear inch) between 8 and 16 to form a non‐chemical barrier to Formosan and Eastern subterranean termites.
