The Bomanite Corp. has released details about a Molded Pulp Former for the production of Grasscrete, a pervious concrete product.
Based on the original European single-use ABS plastic product, this new version of the tool combines the benefits of increased production while eliminating the issue of melting the ABS to create the required voids.
The original “ABS Former” is made from thin-walled, vacuum-formed ABS plastic. The new “Molded Pulp Former” is made from recycled newsprint and various other clean paper byproducts such as post-industrial roll ends and post-consumer circulated print.
The ABS Former is cast into the concrete as part of the pouring process. Once the concrete has adequately cured, the ABS Former tops are burned with torches to open the voids. The Molded Pulp Former uses only simple starch as a binder, which is easily broken down with pressurized water to open the voids.
The ABS Former requires bridging or scaffolding, as it cannot bear the weight of workmen. The Molded Pulp Former can bear even the weight of wheeled concrete.
Grasscrete is a void-structured castin- place concrete product that is continuously reinforced to form the most robust grass concealed or decorative permeable product on the market. Pervious concrete products such as Grasscrete improve the environment through wastewater management, minimization of heat island effect and various other detrimental issues associated with nonporous paving surfaces.
