REGUPOL sound and drain 22 can be installed under fine chippings with concrete tiles but should be checked for stability on-site prior to installation due to the possibility of different mixtures of fine stone chippings that can have different load bearing capacities. To increase stability, pressure resistant thermal insulation ≥ 300kPa can be used. REGUPOL sound and drain 22 is compatible with various roof sealings containing PVC but needs to be approved in each individual case.
