… and how can it affect my construction project?

As you know, Geofoam (key to a geo-composite system) is a product that works wonders for all types of projects, even those that require a special need such as a drainage system. Your construction project may be requiring special insulation for a drainage system, soil stabilization or a combination thereof. Geofoam and a geo-composite or synthetic is the answer of which you seek.

This type of system is designed to create a water/moisture runoff using both Geofoam and a geotextile or two. In deep tunnel projects, for instance, blocks of Geofoam may be fastened or glued together to form an impenetrable barrier covered with geotextile on either side. These geosynthetic materials create soil stability and moisture escape to retain the structure’s integrity. The great thing about this technology solution is that this system can be utilized at depths up to forty feet, and provides protection of up to 80kPa, or 1600-foot pounds of lateral pressure.

Benefits of Using This Form of Geosynthetic Solutions

  • Protection against heave and stress from soil expansion, shifting, movement
  • Lightweight and easy to install
  • Can be brought onsite pre-constructed for speed and efficiency
  • Reduces condensation through dew point shifting to the exterior walls
  • Puncture or deformity of waterproofing membranes disallowed
  • Waterproofing protection during backfill operations
  • Improves R values for insulation purposes (R-3.5 per inch – ASTM C-518) for below grade
  • Relieves hydrostatic pressure
