Base Stone and Finishing Stone beneath Turf Field
Base Stone and Finishing Stone beneath Turf Field
(OP)
I'm working with a client that is installing an Indoor Turf field. When we have worked with turf manufacturers previously they have provided a specification for Base Stone and Finishing Stone. This client has asked us (a Geotechnical Consultant) for a specification. Materials they have submitted are much coarser than what we have seen. Is there a guide for determining the gradation? Is there a reason a gravel is not used? Is there an ASTM standard?
