RHB Fill Silica
Mineral infill completing fibre support and surface stability in synthetic-turf systems.
RHB Fill Silica is a washed, suitably graded silica-sand infill used as a mineral stabilisation layer and for fibre support in synthetic-turf systems. Even distribution between the fibres can add ballast and help the yarn remain upright; in systems with a performance infill it is commonly considered as the lower infill layer. Particle shape and grading, moisture, fines and dust content, purity, packaging and consumption per square metre must be verified for the selected turf model. Unsuitable sharp, excessively fine, contaminated or damp material can cause installation and maintenance problems, so the product must not be treated as interchangeable with ordinary construction sand.
Product and project information
Sand selection and infill rate are designed together with the turf product and field layers.
An infill layer completing the system
Correct particle distribution and application rate support a balanced field build-up.
Fibre support
Helps support turf fibres within the system.
Surface stability
Forms the mineral layer of the infill system.
Project-specific rate
Application quantity is calculated for the selected turf system.
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.
