Color Chart for through mixed concrete:

  • Using integral color for curbing saves a step in the process of installation as the color is mixed in with the concrete and is present upon extrusion. The pigments used are evenly distributed through out the entire dimension of the curbing. With only the outside surface being visible a lot of pigment is “wasted” on the interior. This can become rather costly when brighter, vibrant colors are desired. Another drawback frequently encountered with integrally colored decorative curbing is a higher incidence of efflorescence. Efflorescence is a common, yet unattractive, property of concrete where naturally occurring mineral salts within the concrete migrate to the exposed surfaces and are deposited as unsightly white residue or “staining”. The more porous or open the surface, the more drastic the efflorescence. Typically integral jobs are much more porous then curbing installed with the veneer of curb hardener. This greater porosity typically associated with integral colored curbing also allows for less resistance to staining or other discoloration brought about by weathering and ageing. And when such staining occurs, this porosity makes removal more difficult. Integral color is best suited for situations where the color chosen is a muted earth- tone or a medium grey, an extremely large job where installation time might be a cost consideration or where the long term appearance is of low consideration.
