RHB Grass DrainTex

RHB Grass DrainTex is a geocomposite drainage layer considered for compatible artificial-turf sub-base build-ups to convey water laterally towards drainage outlets and limit mixing between adjacent layers. It is a thin roll system in which a three-dimensional polymer drainage core works with a geotextile filter or separation face; it is not a direct substitute for a perforated collector pipe. In-plane flow capacity under pressure, core thickness, geotextile properties, overlap and connection details, gradient, outlet spacing, imposed load and compatibility with upper layers require project-specific review. Final use is defined after hydraulic assessment and verification against current technical documentation.
