Commercial Development

A Multi-Layer Base with Dual-Metalized Film Technology

The Land Science research and development team of scientists have invested years in developing the TerraShield vapor barrier system, which delivers orders of magnitude higher vapor intrusion protection as compared to any other composite vapor barrier system. The innovative use of two separate layers of aluminum combined within flexible polyethylene results in the TerraBase layer having >100X greater chemical resistance compared to HDPE (10mil)1.

Nitrile-Advanced Spray-Applied Technology

Land Science researchers have developed a break-through technology which incorporates nitrile into the spray-applied core formulation, a material known for its superior chemical resistance. The resulting spray-applied core barrier offers an improvement of up to 10X in chemical resistivity and protection over any other spray-applied barrier in the market today1.

Reduce Your Liability

When developing properties on sites with known environmental impacts, one of the biggest issues is the risk to human health. Failure to address these issues can result in adverse health effects and millions of dollars in legal exposure. TerraShield was designed specifically to eliminate risk of exposure by employing innovative technologies to provide best-in-class chemical resistance and durability. Backed by a robust warranty and installed by Land Science-certified applicators, each TerraShield installation is rigorously tested to ensure the quality of every seal and ultimately the complete vapor barrier system installed.

  • TerraBase lab-tested to be 100x more effective than 10 mil HDPE sheets
  • TerraCore nitrile-modified core laboratory tested to be up to 10x more effective than spray-applied asphalt latex core material
  • Highest level of protection available in a vapor barrier system
  • Land Science Certified Applicators ensure barriers are properly installed, reducing risk

The TerraShield System

TerraShield Bond is a proprietary protection layer comprised of high-density polyethylene (HDPE) thermally bonded to a geotextile fabric. The bond layer is placed over the Nitrile Core to:

  1. Enhance the curing of the membrane
  2. Increase puncture resistance
  3. Provide the ability to bond the vapor barrier directly to the underside of the concrete slab

The nitrile core is applied at 40 mils, is sprayed to the TerraShield base layer, it seals the seams of the base layer, as well as, around penetrations and perimeter terminations.

TerraBase is a patent-pending 25-mil thick composite geomembrane comprised of double layers of flexible chemically resistant HDPE and metalized films PET/ MET, laminated to a tear resistant woven polyethylene and a high puncture reinforcement geotextile.

TerraVent is a low-profile, trenchless, flexible, sub-slab vapor collection system used in lieu of perforated piping. It consists of a heavy duty 3-dimensional, high flow, polypropylene dimpled core. The core is then wrapped and bonded with a non-woven geotextile to prevent soil, sand or gravel pass into the dimple core. TerraVent core is made from 100% Post-Industrial/Pre-Consumer polypropylene regrind material.
