Any damage from aeration tines?
The standard yard or athletic field design calls for an overall depth of 13″-14″, which still provides a 7″-8″ cover of sand over the crown of the EPIC chamber before seeding or sod placement. A six inch tine would not damage the chambers, however the recommended tine length is 3″-4″ such as a Ryan L28. • What issues are there with western soils, salt content, salt crusting etc.? Unless natural sand is actually available on the construction site, the 13″-14″growing matrix of the EPIC bed is actually imported washed sand, where the manufacturing process has probably eliminated most of the soluble salts from the sand. See choosing the right sand flyer in the handouts. As such the nature of native soils has no relevance, as the system is isolated from their influence. We have installed two back yards in high Boron subsoil area, but since the water source for watering is different from the natural ground water below the bed, the boron has no influence on the EPIC beds.
