A detectable warning system comprising:
- a mat substrate comprising a first layer comprising acrylic cement, acrylic admix, and aluminum oxide and a second layer comprising the acrylic cement and the acrylic admix but not the aluminum oxide;
- and
- a texture layer comprising a plurality of texture elements formed from a second acrylic material disposed on a top surface of the mat substrate;
- and
- wherein:
- the mat substrate comprises a plurality of raised portions;
- the first acrylic material comprises an acrylic cement and an acrylic admix;
- the second acrylic material comprises the acrylic cement and the acrylic admix;
- and
- the plurality of texture elements comprise texture elements that are of a variety of different sizes and shapes positioned about an upper surface of the mat substrate.
A method for making a detectable warning system comprising:
- providing a mat substrate made from a first acrylic material and comprising a plurality of raised features on a support surface of a fabrication facility;
- preparing a texture element mixture comprising a second acrylic material;
- and
- applying the texture element mixture to a top surface of the mat substrate to form a plurality of texture elements about an upper surface of the mat substrate;
- wherein:
- the first acrylic material comprises an acrylic cement and an acrylic admix;
- the second acrylic material comprises the acrylic cement and the acrylic admix;
- and
- the texture element mixture does not include any sand.
A mat substrate comprising:
- a top surface comprising a plurality of raised portions;
- a first acrylic layer comprising an acrylic cement, an acrylic admix, and an oxide material;
- and
- a second acrylic layer comprising the acrylic cement, an acrylic adhesive, and the acrylic admix;
- wherein the first acrylic layer defines the top surface and the second acrylic layer is configured to be positioned below the first acrylic layer when the mat substrate is in an operable position.
