Concrete paving stones have a smooth, thin paste on the surface. Over time, this smooth surface can wear exposing the white or grey aggregates inside the concrete and making the paving stone appear discolored or faded. EnduraColor technology uses a two-step manufacturing process to create a paver that resists the look of fading, without sacrificing the strength you expect. First, coarser aggregates are added to the concrete composition of the stone’s base to create a stronger concrete formulation. Then, under several tons of vibrating pressure, concentrated color and finer aggregates are pressed into the top of the stone. This protects the surface from the appearance of fading because the top layer prevents large, lighter color aggregates from ever showing through.
