Abstract

A modular safety unit having a skid resistant surface for use in a location where it is desirable to add a skid resistant surface for traction comprising a base made of resin, the base having a top side and a bottom side; an aggregate made from calcined bauxite, and wherein the aggregate is attached to the top side of the base; and an adhesive having a top side and a bottom side wherein the top side is attached to the bottom side of the base and wherein the adhesive bottom side may be selectively attached to a location where it is desirable to add traction.

Claims

1. A modular safety unit having a skid resistant surface for use in a location where it is desirable to add a skid resistant surface for traction comprising:

a) a base made of resin, said base having a top side and a bottom side;

b) aggregate made from calcined bauxite wherein said aggregate is attached to said top side of said base; and

c) an adhesive having a top side and a bottom side wherein said top side is attached to said bottom side of said base and wherein said adhesive bottom side may be selectively attached to said location where it is desirable to add traction, and wherein said location is not a substrate.

2. The modular safety unit according to claim 1 wherein said calcined bauxite has been colored through pressurizing.

3. The modular safety unit of claim 2 wherein said resin is polyurethane.

4. The modular safety unit of claim 3 wherein said polyurethane is cold mixed.

5. A modular safety unit having a skid resistant surface for use in a location where it is desirable to add a skid resistant surface for traction comprising:

a) aggregate made from calcined bauxite;

b) a base made from resin having a top side and a bottom side wherein said aggregate is attached to said top side of said base;

c) a substrate having a nosing for use with stairs, a top side and a bottom side wherein said top side is attached to said bottom side of said base wherein said substrate reinforces said base; and

d) an adhesive having a top side and a bottom side wherein said top side is attached to said bottom side of said substrate and wherein said adhesive bottom side may be selectively attached to said location where it is desirable to add traction.

6. The modular safety unit according to claim 5 wherein said substrate is plastic.
