Claim:
1. A device for fixing an item to a surface of a building structure incorporating a waterproof membrane, the device comprising a base plate having a plurality of through-holes in it to enable the base plate to be fixed to the building structure beneath the waterproof membrane, at least one fixing member projecting from one side of the base plate, the waterproof membrane extending across the base plate and having an aperture through which the fixing member protrudes, an impermeable cover member over the fixing member, covering the aperture in the waterproof membrane and including means to attach the item thereto, in which the cover member is engaged on the fixing member so that the waterproofing membrane is compressed between the base plate and an underside of the cover member facing toward the base plate to form a waterproof seal with the waterproof membrane, and further comprising a spacer, separate from the base plate and the cover member, having upper and lower surfaces, a thickness, and a diameter less than a diameter of the aperture so that the lower surface of the spacer contacts the upper surface of the base plate while the upper surface of the spacer contacts the underside of the cover member; the spacer being located around the fixing member between the surface of the cover member facing closest to the base plate and the upper surface of the base plate; in which the thickness of the spacer fixes a distance between the underside of the cover member and the upper surface of the base plate to preclude overcompression of the membrane.
