Presto Geosystems, the original inventor and global leader in geocell technology, introduces the ATRA® Wall Key for their GEOWEB® Retaining Wall System. The ATRA Wall Key is a device used to connect adjacent GEOWEB Retaining Wall sections through the GEOWEB material slots (I-slots).
Made of non-reactive, chemically inert high-density polyethylene, the ATRA Wall Keys provide a more secure and permanent mechanical connection over staples or zip ties, and they are the only geocell connector specifically designed for use in exposed wall face applications. Formulated to withstand weathering and ultraviolet radiation, the ATRA Wall Keys will not corrode or photodegrade, even when exposed to harsh environments. Securing sections with the Wall Keys is faster than using staples or zip ties, requires no tools, and can be completed by one installer with one easy turn.
The ATRA Wall Key includes an integrated washer at the base of the handle for coverage of the I-slots when connecting adjacent wall sections, frictional barbs for an improved interlock with the GEOWEB sections, and an ergonomic handle with S-shaped contouring for ease of installation. They are the most effective way to connect the GEOWEB Retaining Wall sections, ensuring the long-term success of your project
Presto Geosystems’ patented GEOWEB® cellular confinement system been installed on thousands of projects in every geographic region in the world, and is the only geocell technology that has stood the test of time for over 40 years.
