Wedge system

An improved wedge of the type forming part of a wedge system used with tiles and mortar for creating a tiled surface having an array of the tiles arranged in substantially coplanar side-by-side evenly spaced relation, the wedge system including:

• wedge receivers, each having a planar element and a resilient hook element extending from the planar element in substantially perpendicular relation:
• the hook element having an aperture defined therein, each hook element, in use, being disposed in the manner of a tile spacer between a pair of adjacent tiles in an array of the tiles laid in the mortar, thereby to provide for said substantially even side-by-side spacing of the tiles;
• and the planar element, in use, being disposed beneath the pair of adjacent tiles;
• and
• wedges, each having a clamping surface and a ribbed gripping surface orientated in angular relation to one another to meet in an edge, each wedge, in use, extending through the aperture of a respective receiver such that:
• the planar surface of the wedge is positioned in abutting relation against the pair of adjacent tiles;
• and the hook element is resiliently deformed, to provide for a clamped engagement of the pair of adjacent tiles between the planar surface of the wedge and the planar element, thereby to provide for said substantially coplanar relation
• the gripping surface grips the respective wedge receiver, to resist withdrawal of the wedge from the aperture and maintain the clamped engagement until the mortar has cured,
• wherein the improvement comprises an arcuate arrangement of the ribs.
