To place many tiles/boxes, you can easily use nested #while() loops
Sample:
union{ // place 1600 tiles
#declare IndX = -20;
#declare MaxX = 20;
#declare MaxZ = 20;
#while(IndX < MaxX)
   #declare IndZ = -20;
   #while(IndZ < MaxZ)
    box{<0.45,0.02,0.45>,<-0.45,-0.1, -0.45> translate <IndX, 0, IndZ>}
    #declare IndZ = IndZ + 1;
   #end
   #declare IndX = IndX +1;
#end
plane{y, 0 pigment{rgb 0.05}}// grout between the tiles
pigment{rgb 1}
}

You can also use layered textures on a plane:

texture{pigment{gradient z color_map{[0.1 rgb 0.05][0.1 rgb 1]}
// white base with black stripes
texture{pigment{gradient z color_map{[0.1 rgb 0.05][0.1 rgbt 1]}
// second set of black stripes
// The transparent part let the previous layer be visible
