Efficiently installable and durable embedment tile for producing tactilely-detectable surfaces

A method for producing a tactilely detectable surface in a moldable material, comprising the steps of:

• a) providing an embedment tile comprising:
• i) a tile member substantially planar in form, having an upper surface and a lower surface, the upper surface having a plurality of projections extending upward therefrom;
• ii) a plurality of moldable material cross beams anchors joined to the lower surface of the tile member, each moldable material cross beam anchor having a pair of side walls, each having a lower edge portion joined to the lower edge portion of the other side wall to define a substantially enclosed chamber, and the side walls have a plurality of moldable material openings into the chamber;
• and
• iii) a plurality of support members, each support member being attached to the lower surface of the tile member and projecting downward a distance therefrom, the distance defining a depth greater than that of the moldable material cross beam anchors;
• b) placing the moldable material embedment tile into the moldable material;
• c) allowing moldable material to flow through the cross beam moldable material openings and into the moldable material cross beam anchor chambers;
• d) positioning the upper surface of the tile member relative to a surface of the surrounding moldable material so that the projections are exposed;
• and
• e) allowing the moldable material to cure in the chamber and the moldable material openings to form a substantially continuous cured material between the chamber and cured material surrounding the moldable material cross beam anchor.
