Hi All, having had our wet ufh system installed we now have to angle grind a path in the screed for the conduits in which the floor sensor probes run to lie, before installing the engineered floor above it. We're struggling to find a small enough diameter conduit which will allow us to cut a shallow path in the screed, as the larger the diameter of the conduit, the deeper the path which is a problem for obvious reasons. We're therefore calling upon your knowledge again, as any suggestions as to a conduit which might suit would be gratefully received. Thanks!
