Written by William G Handlos, P.E. Presto Geosystems is the maker of the Genuine GeoBlock® family of rigid vegetated porous pavement products. We’ve been manufacturing porous pavements since 1978 and have been a leader in the industry ever since. It’s safe to say we were pretty comfortable with our understanding of the differences between our products and our competitors in the market….or so we thought.  We knew our products were premium performers offering the best structural modulus (load spreading snowshoe effect), more structural high density polyethylene per square foot than our competitors, load transfer tabs to assure no separation at joints and an industry-leading warranty. Our competitors on the other hand  go with much lighter density product design and some offer their products on rolls like carpet or rolls of sod.   We knew a product that comes on a roll was not a very effective load transfer device. After all, the whole point of vegetated porous pavement is to protect the topsoil (and therefore the root system) from damaging compressive forces and to transfer those forces to the layer below the topsoil – preventing rutting and offering a stable riding surface for fire lanes, overflow parking, or occasional use… Read more »
