ACS Stone Restraints

ACS Stone Restraints are designed to provide lateral restraint against positive and negative windloads as well as any possible imposed loads that may be subjected to a stone façade in normal service. Stone restraints are typically designed complete with a one-way or two-way welded or loose dowel that should be embedded no less than 25 mm into the stone.

The restraint fixing should be located at 1/5 points for stack bonded stones and 1/4 points for stretcher bonded stones. If this is not possible the fixing should be located at least 75mm from the edge of the stone. The maximum distance between restraint fixings should be 1200 mm unless the stone and fixing method have been proved by structural calculation or physical test and there should be a maximum of four fixing points per stone which can be located in the horizontal or vertical joints. ACS Design the Stone Restraints to suit the specific application taking into account the applied windload, cavity, required water resistance and the substrate into which the restraint tie is being fixed. Typical fixings are detailed in the table below.
