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.

Product and surface system questions
How are service life and warranty terms determined?
Service life depends on the selected product, usage intensity, climate, installation and maintenance. Request the written warranty duration and scope using the product code. This page does not promise a common service life or UV warranty for every product.
What evidence is needed for use in a children’s play area?
Suitability cannot be established from the turf appearance or product name alone. Intended use, the base, any impact-absorbing layer and infill must be assessed together. Request relevant test reports by product and system code; do not assume safety or compliance before the report scope is verified.
How is drainage assessed in wet conditions?
Drainage must be assessed using the selected surface’s water permeability together with the sub-base, slope and drainage outlets. Share the project location and existing base details to request the product datasheet and installation requirements. No universal promise of no ponding or a fixed drainage rate is made.
