Improvements in or relating to sealing assemblies

摘要

An apparatus 100 for providing a watertight seal between an earthing rod 106 and a building structure having a waterproof membrane 128. The apparatus comprises a tube 110 that allows the earthing rod 106 to pass through, a housing having a first seal 114 for preventing the passage of moisture between the earthing rod and the tube and a bore 104 for receiving the tube. The first seal is disposed between an inner surface of the housing bore and the earthing rod. A second seal 112 for preventing passage of moisture between the tube and the waterproof membrane is disposed between the housing and the tube. The apparatus also comprises a clamp having upper 120 and lower clamping members 130 for clamping the waterproof membrane therebetween. The upper clamp member forms part of the housing and the lower clamp member is an adjustable collar movably attachable to the housing so as to accommodate different thicknesses of waterproof membrane.
