Expanda Joint is also available in a custom-cut length for less wastage. This unique product is designed specifically to overcome slab alignment problems, provide for thermal expansion of adjacent slabs and offer a system that allows continuous concrete slab pours. Expanda Joint is made up of Danley® Keyjoint with a 5 mm close cell foam attached. This allows expansion of the concrete, giving a highly effective, cost efficient expansion joint system with a joint finish second to none. Knockouts allow use of 16 and 20 mm Dowelmaster® sleeves and square dowels. Sizes to suit 100 to 250 mm thick slabs. Enquire at your local OneSteel Reinforcing branch for your specific requirements.
