The Diamond Dowel system is popular because they are so quick and easy to install

The Lesa Diamond plate dowel system uses plate dowel technology to replace traditional dowels in concrete slabs where final joint widths will not exceed 15mm.

The Lesa Diamond plate dowel system consists of two parts. The first being a high-quality, high-density, one-piece plastic nail on sleeve. The second being a 6mm tapered steel plate. The tapered plate dowel system enables the sleeve to be cast into new slabs without having to penetrate formwork, thus eliminating damage to the forms.

The built-in ring shank nails make installation quick and easy and also ensure accurate dowel alignment. This is achieved by the sleeve generating a precise void in the concrete into which the tapered dowel plate can be inserted at the optimum time of construction.

The tapered sleeve allows progressive lateral movement as the concrete shrinks and cures. The construction of the sleeve is such that it ensures once the dowel plate is inserted into the sleeve an effective seal is formed around the dowel to prevent concrete slurry from entering the sleeve.

Note: Where joint widths are expected to be greater than 15mm, use Lesa System's Dominator or Hi-Move plate dowel system. Dowels are available in black steel, stainless steel, or hot-dip galvanised. For spacing and suitability of Lesa tapered plate dowels, please refer to Lesa System's dowel charts. Note: Lesa tapered plate dowels are not available in all countries and equivalent dowels may be substituted.
