Choosing the Right Geocell

Written By: Bryan Wedin P.E., Chief Design Engineer, Presto Geosystems Not all geocells are created equal. While most manufacturers can provide similar-looking written specifications, you need assurances that the material delivered for your project is of the high quality that you expect. Important factors in the success of your geocell project include: Quality The geocell material is proven, strong, and will last Require only the highest quality virgin High Density Polyethylene (HDPE) resin Low quality or recycled resin can lead to weak and/or inconsistent seam strength, putting the success of your project at risk. Non-HDPE materials cannot match the nearly 40 years of in-ground experience of HDPE geocells and plastic alloy proprietary blends can mask cheap stiff filler materials. ISO Certification Important, but the manufacturer sets the testing protocol for the certification. Require a Certificate of Analysis (COA) for the material that is shipped to your project. An ISO certification that does not require continuous testing is lacking. Integral Components The complete solution includes proper components Non-corrosive, high-strength panel connection method (ATRA® Keys vs. weak staples or zip ties) Anchors that provide secure connections to the geocell (ATRA® stakes vs. J-hooks) Load Transfer Devices for tendon applications that are non-corrosive and… Read more »

Use Product Differentiation for Good, Not for Evil

Written by William G Handlos, P.E. Product differentiation is often thought of as a way to create a competitive advantage. Typically, a company decides to focus and promote upon a certain attribute(s) of a product making this attribute a key feature of their value proposition statement. For example, a major automobile company might focus and promote a rear lift gate automatic opener actuated by the movement of the driver’s foot under the rear bumper. This inexpensive addition to an SUV’s feature set may be the difference in a buying decision between competing automobile brands, particularly in a market with fierce competition and similar option sets.  In this case, the manufacturer has created a product differentiator that truly adds benefit to the customer. Presto Geosystems® developed the original geocell in the late 1970s and GEOWEB® Geocell product enhancements have been developed every few years, always with the intent of offering benefits to their customers with each refinement. For manufacturers who sell to contractors who bid on projects that are based upon engineered plans and specifications, the waters can be murkier. Is product differentiation created for the benefit of the customer or is differentiation simply crafted to create a unique set of… Read more »
