Seminars / CPD

Consultants from CRM can give technical seminars both in the area of conventional roof drainage and siphonic roof drainage. Both Ray Baker and Malcolm Wearing have experience lecturing at Salford University, in the fields of hydraulics and drainage. All courses can be given in an abridged format to suit lunchtime or evening meetings if required.
