Title (EN) IMPROVEMENTS IN AND RELATING TO SURFACING BLOCKS
(FR) PERFECTIONNEMENTS APPORTES A DES BLOCS DE REVETEMENT
Abstract:
(EN) A surfacing block (1) has upper and lower surfaces (2, 7) of a generally cruciform shape. Around the boundary of the surface of the block are projections (8) and/or recesses (9) for interlocking engagement with recesses and/or projections of a neighbouring block. The block has a groove (10) in its upper surface and a drainage slot in the groove (10) such that when the block is located in interlocking engagement with a neighbouring block, a drainage channel (12) extends from the upper surfaces of the blocks to the lower surfaces of the blocks. The risk of water accumulating on the upper surfaces of the blocks can therefore be reduced.
(FR) L'invention concerne un bloc de revêtement (1) comportant des surfaces supérieure et inférieure (2, 7) de forme généralement cruciforme. Sur les contours de la surface du bloc se trouvent des saillants (8) et/ou des évidements (9) permettant une liaison de forme avec des évidements et/ou des saillants d'un bloc voisin. Le bloc présente dans sa surface supérieure une rainure (10) dotée d'une fente de drainage de sorte que, lorsque le bloc est en prise par liaison de forme avec un bloc voisin, un canal de drainage (12) s'étend des surfaces supérieures des blocs aux surfaces inférieures de ces derniers. Le risque d'accumulation d'eau sur les surfaces supérieures des blocs peut donc être réduit.
