  • Patent number: 9027290
    Abstract: An embedment tile for producing a tactilely detectable surface in a pedestrian walkway. The tile includes a pattern of upwardly extending projections on its upper surface forming a tactilely detectable pattern, and the projections have reinforcing ridges to protect the projections from lateral forces such as those applied by snow plows.

  • Patent number: 8146302
    Abstract: Disclosed is an embedment tile for producing a tactilely detectable surface in a moldable material and method for using same. The tile comprises a tile member having a pattern of upwardly extending projections on its upper surface forming a tactilely detectable pattern, and a cross beam joined to the lower surface of the tile member. The cross beam defines a hollow chamber and apertures to allow for the release of air and inflow of moldable material to secure the embedment tile when the moldable material hardens. The cross beam can define a lower open portion at a cross beam end portion that eases installation by permitting a more direct flow path into the chamber for moldable material. The embedment tile can also include a reinforcing member joined to the lower surface of the tile member and/or a transverse reinforcing member joined to a lower surface of the tile member.
