Stone Tile Control Joints by Unison Joints

Building materials expand and contract as an effect of thermal changes. Control joints offer a provision for planned cracks allowing for concrete movements caused by temperature and moisture changes. In other words, after concrete is poured and it cures and hardens, it starts to shrink. This process creates tension and stress on the concrete slab, which could eventually lead to cracking on the surface of the floor finish.

Control joints are placed strategically to regulate the cracking in a line instead of randomly appearing across the floor finish. Stone tile control joints are designed to relieve unsightly surface cracks by gathering, distributing and dissipating stress forces induced by thermal fluctuations and presence of moisture. Without control joints, there could be a possible adhesion loss between the floor finish and substrate which can damage the entire surface covering.

Hard floor finishes such as terrazzo, granite, tiles and marble are no exception to the changes caused by heat and moisture. Stone tile control joints are an essential part when installing hard floor finishes. They can blend or accentuate the design features and render the joints unnoticeable when specifiers take the time to design the control joints into their installation together with the design of the surface covering.

Neo A Control Joints from Unison Joints
Neo A control joints are manufactured according to Australian and International Standards. Designed to accommodate the difference in coefficient of expansion between hard floor finish and the concrete substrate when there is thermal movement. Neo A control joints are designed to withstand heavy loads and frequent foot traffic. The ideal control joint system for hard floor finishes like tiles, granite, terrazzo and marble.
