The present disclosure provides a method for producing detectable warnings (16) on substrate surfaces (14), which includes providing a mat (30) with a top surface (38) and a bottom surface (36) and a pattern of mat through holes (34) extending through the mat (30). The through holes (34) comprise a lower portion (44) defining a lower mat opening (33) and an upper portion (32) defining an upper mat opening (35), wherein the upper mat opening (35) is larger in transverse dimension than the lower mat opening (33). The method further includes placing the mat (30) on a substrate surface (14), wherein the bottom surface (36) of the mat (30) is adjacent the substrate surface (14), and injecting into the mat through holes (34) a viscous substance (40) having the ability to cure into a solid. The method further includes removing the mat (30) at the appropriate time to form raised detectable warnings (16) on the substrate surface (14).

L'invention concerne un procédé de formation d'avertissements détectables (16) sur des surfaces de substrat (14), qui comprend la fourniture d'un mat (30) présentant une surface supérieure (38) et une surface inférieure (36), et un motif de trous traversants de mat (34) s'étendant à travers le mat (30). Les trous traversants (34) comportent une partie inférieure (44) définissant une ouverture de mat inférieure (33), et une partie supérieure (32) définissant une ouverture de mat supérieure (35), l'ouverture de mat supérieure (35) étant plus grande dans la dimension transversale que l'ouverture de mat inférieure (33). Le procédé comprend en outre le placement du mat (30) sur une surface de substrat (14), la surface inférieure (36) du mat (30) étant adjacente à la surface de substrat (14), et l'injection dans les trous traversants de mat (34) d'une substance visqueuse (40) ayant la capacité de durcir en un solide. Le procédé comprend en outre l'enlèvement du mat (30) à un moment approprié pour former les avertissements détectables en relief (16) sur la surface de substrat (14).
