Thanks to the application of BAUFIX® inserts, the floor can be used immediately – there is no need to observe the 28-day period to decrease the humidity level of the concrete, obtain the complete chemical contraction and a major part of physical contraction, as it is required in case of silicone or polyurethane fillings. BAUFIX® inserts are suitable for expansion and contraction joints measuring 5-7 mm in width and no less than 30 mm in depth. The edges of the expan-sion joint must be bevelled at the angle of 45o which will ensure that the full adhesion of the insert and complete protection of the edges. The insert is installed by striking it into the joint with a wooden or rubber hammer. BAUFIX® inserts can be used as temporary filling during the initial period of using the surface, protecting the edges of the expansion and contraction joints from damage. This makes it possible to begin the temporary use of the floor and recover the insert while applying the target sealants.

Thanks to its good functional parameters, BAUFIX® inserts may also remain as the final filling of expansion and contraction joints.
