Using LRM’s innovative new STF Sheetless ThermoForming™ process, Cultec, Inc.’s large thermoplastic stormwater chambers are produced in one step, without the pre-formed sheet of a conventional thermoforming mold.
A product identification stripe is laminated in-line as the molten high density polyethylene is coated or draped directly onto the mold.
These products are produced by LRM today in two sizes, weighing 44 and 68 pounds respectively.
