Continuous Rod Holdown Systems

Earthbound Systems
More information: http://www.holdown.com/

Background

Threaded rod systems have been used in the United States since the early 1980s.  The Earthbound System was the first system in 1997 to get ICBO approval on a rod system with the world’s first wood shrinkage compensating fastener.  Earthbound has advantages over the other systems due to the fact they manufacture their own shrinkage fasteners in Washington State.  Earthbound uses 100% domestically manufactured threaded rod and couplers.  They manufacture their own color coded (an industry first!) bearing plates also.  Their shrinkage fastener is the only one that has proven corrosion resistance with 1,000 hours salt spray testing and still able to prove actuation.

Engineers design your own runs

We invite you to design your own Earthbound runs using Earthbound’s online Run Builder tool at http://www.runbuilder.com.  There is no software for you to download and install locally.  It is all run from the web browser.  We support IE 8 and Firefox.  The online RunBuilder tool will create up to 6 story continuous rod system runs, including automatic component sizing and wood compression requirements and shows it all graphically in PDF!  Calculations and DXF files of the actual run are also included.  Right now the RunBuilder is using ASD loads for the U.S.  We will have Canadian Limit States version by end of 1st quarter 2010.  Please see the links below for Limit States design information!

Flexible Fabric Concrete Forms

More information: http://www.layfieldgeosynthetics.com/pages/Products/default.aspx?id=3111

Flexible fabric concrete forms allow the designer to place a hard, concrete material in locations where previously it was impossible to form concrete. The flexible fabric concrete forms can be placed on almost any surface (even underwater). The form is pumped full of a structural grout for maximum strength. Once hardened, the concrete provides permanent protection. These systems are used for erosion protection, for protection of geomembranes, and anywhere else where a hard surface is required and concrete forming is a problem.

Flexible fabric concrete forms are often used for shoreline protection where the concrete layer protects the embankments from wave and wind action. Other uses of flexible fabric concrete forms are to line channels, canals, outfalls, splash pads, and run-off ditches. Flexible fabric concrete forms are occasionally used to protect slopes from erosion, and to line the collection ditches and splash pads at the base of steep slopes.
