Product catalog summary
Product Description
GeoVent™ is a three-dimensional vent core wrapped in a non-woven, needle-punched filter fabric. It is designed for use with GEOVENT active/passive gas venting systems, including end outlets.
Application
GeoVent™ is intended for active or passive venting applications, particularly when used with CETCO vapor intrusion mitigation systems.
Benefits
  • Direct installation on subgrade, eliminating the need for trenching and reducing the risk of damaging existing underground utilities.
  • Proximity to vapor intrusion barriers enhances the effectiveness of gas venting.
  • Higher ventilation efficiency due to greater opening area per linear foot and integral filter fabric.
Physical Properties
  • Compressive Strength: 8,500 - 11,000 psf (407 - 527 kN/m²) as per ASTM D 1621.
  • Thickness: 1.0 in. (2.54 cm) as per ASTM D 1777.
  • Flow Rate: 30 gpm/ft width (372 lpm/m) with a hydraulic gradient of 0.1 as per ASTM D 4716.
Packaging
Available in rolls of 1 ft. x 165 ft. (0.3 m x 50 m).
Testing Data
  • A.O.S.: 70 US Sieve (0.212 mm) as per ASTM D 4751.
  • Grab Tensile Strength: 100 lbs. (0.45 kN) as per ASTM D 4632.
  • CBR Puncture Strength: 250 lbs. (1.11 kN) as per ASTM D 6241.
  • Flow Rate: 140 gpm/ft² (5,704 lpm/m²) as per ASTM D 4491.

GEOVENT-1

TECHNICAL DATA DESCRIPTION GEOVENT™ consists of a three-dimensional vent core that is wrapped in a non-woven, needle-punched filter fabric. GEOVENT End Outlets are available for use in conjunction with GEOVENT active/passive gas venting systems. APPLICATION GEOVENTrM is designed for use in the following application: • An active or passive venting when used with CETCO vapor intrusion mitigation systems. BENEFITS • Installed directly on subgrade eliminating trenching and potential interference or damage to existing underground utilities • Placed in closer proximity to the vapor intrusion barrier allowing for more effective venting of any accumulated gas • Greater opening area per lineal foot of pipe and integral filter fabric allows for higher ventilation efficiency TESTING DATA GEoVENT™ allows for ease of installation directly on the subgrade, eliminating the need for costly and labor-intensive trenching.
