Abstract: A compliant trim for use between concrete slabs is disclosed, intended for the replacement of wood commonly used for formwork to divide concrete slabs. The compliant trim is easily inserted into the space cleared of wood, will not migrate deeper into the space, and is therefore independent of the depth of the cleared space beyond a minimum needed for installation. Additionally, the compliant trim lies flush or below the surface of slabs which have edge radii, making it relatively unaffected by foot traffic, vehicles, and the like. The trim may be extruded, may be manufactured from recycled materials, and remains compliant to allow for joint expansion and contraction.

Abstract: A barrier to fluid passage is embedded within, instead of atop, porous material to retain the durability of the surface of the porous material. In one embodiment, a thin set mortar is applied to a concrete slab. A pleated metal foil is pressed into the wet mortar and a bond is established. The mortar is allowed to set and a top, or finish, section of concrete is then poured over the foil and finished conventionally. Provisions are made for sealing expansion joints in concrete slab floors and at the juncture of floor and wall. The foil may be provided in multiple layers to provide a mechanical bond via mortar oozing through perforations or along pleats in each of the top and bottoms layers, while providing a solid layer through which a fluid will not pass, at least in one direction.
