The Most Efficient Geocell Connection Device

The most productive way to connect GEOWEB sections, and assure the longest performance is with ATRA® Keys.  3X stronger than staples, they provide a more secure and permanent load-transfer connection—and the polymeric material won’t corrode, even when exposed to corrosive environments. 3X faster than stapling, ATRA keys are easy to install with just one worker, and assure a positive connection with one easy turn! No pneumatic staplers. No jams. No compressors. No hassles. Watch the comparison video

Durable Polymer Won’t Degrade.

The ATRA key’s inert polymer material will not degrade or corrode like staples so the connection strength and performance remains the same for the life of the installation.

Three Times Faster Than Stapling.

Field testing revealed the ATRA key is three times faster than stapling operations. GEOWEB sections are quick to connect with a simple turn of the ATRA key.

Three Times Stronger Than Stapling.

Performance research confirmed the pull out strength of the ATRA key is three times stronger than stapling. Stapling can fail with a “zipper effect” where each staple can disengage.

Connection Certainty.

ATRA keys inserted through defined cell wall i-slots ensure the required connection is made. With stapling, contractors seldom use the recommended number of staples per connection, creating a weaker connection point.

Labor Savings. One Worker vs. Two for Stapling.

Only one worker is required per connection point with ATRA keys. Stapling requires two workers on each connection point –one to hold the sections together and the other to staple.

No Compressors or Equipment Required.

ATRA keys do not require any additional equipment. Stapling requires air compressors, generators, staplers and staples -the equipment and hoses must be continually moved around the jobsite.

Hassle-Free Connection.

GEOWEB sections are made with ‘i-slots’ for easy installation of ATRA keys in any soil or weather conditions. Staplers are prone to chronic problems with misfires and jamming, especially at wet, muddy or sandy sites.

Safer for Workers.

Using ATRA keys instead of stapling eliminates potential for hand injuries caused by staplers, and user movement of equipment and hoses.

ATRA Key Advantages Compared to Stapling

  • Labor Savings: Laborers can work independently to connect GEOWEB sections instead of requiring two laborers for stapling operations. Connection time with ATRA Keys is nearly three faster than stapling.
  • Equipment Savings: Eliminates the requirement and cost for air compressors and pneumatic staplers and the down-time expense of operating staplers in a construction environment.
  • Accessibility and Portability: Easy to work with on any grade and easy to transport to remote or difficult-to-access locations.
  • Safety: Eliminates worker injuries associated with jammed or misfired staplers.
