Expanda Joint is a unique product in that it is designed specifically to overcome slab alignment problems, it provides for thermal expansion of adjacent slabs and offers a system that allows continuous concrete slab pours. Expanda Joint is made up of Danley™ Keyjoint with 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.

Similar to Keyjoint they are self supporting and height adjustable with drive’n’twist stake system. They can be uses as plain joint or have a temporary or permanent capping applied (sold separate). Expanda Joint is available in both 3 m and 6 m lengths, made to order. It has knock out holes for 16mm or 20mm square dowels every 150 mm given flexibility in centres (150 mm, 300 mm, 450 mm and 600 mm) as standard. The Danley™ Dowelmaster™ system can attach to these holes given a full joint system of dowels, sleeves and formwork.
