Abstract

A barrier layer comprises a base layer A, a screed B incorporating heating elements 1 and temperature sensors 2. Above the screed B is an insulant layer C separated by a vapour seal D, and a wearing slab E. The cold area F is above the wearing slab E. It is desired that the 0{C isotherm should be kept generally at the position G indicated within the wearing slab E. The heating elements 1 will be heated individually and in sequence as necessary to maintain the temperature of each heating element within a range of +3.0 to +4.5 DEG C through circuitry controlled by the sensors 2. <IMAGE>
