COFLEX CTM By PROFILITEC
Collection: Coflex
Type: Movement joint suitable for grinding
COFLEX CTM - Twin metal plate - grindable infill expansion joint, specifically conceived for terrazzo floor laying, marble, granite, limestone covering jobs necessitating sanding, grinding and/or polishing finish treatments on site, which must necessarily be borne easily by the joints as well. Suggested flooring bays 16 sqm. Settlements of the structure, expansion and compression due to thermal excursion, shrinkage and structural bending are elements that create continuous movements and stresses in the flooring, which often generate problems of cracking or premature detachment of the covering. It is therefore advisable to provide an adequate grid of expansion joints during installation, choosing the type of joint and its location in consideration of the loads and stresses to which the coverings will be subjected, and the different coefficients of linear thermal expansion of the bedding and tiles and the possible interactions between different materials. The splitting of the surface and the screed underneath is in fact decisive in order to guarantee a workmanlike laying in both adhesive and traditional methods. Always provide for a joint: - In correspondence with a change in the substrate material and/or the joints. - At pre-existing discontinuities in the substrate, such as structural expansion joints and different screed blocks. - At fixed elements such as columns and doors. - At changes in the laying direction. - At points where the tiled surface meets walls or containing elements. The resulting modules should be as even as possible. In general, the proportion between the two sides should not exceed 2:1.
