Bespoke Stone Drip grooves

If you are planning to use natural stone for a wall coping stone don't forget to insert drip grooves.  A drip groove is a 5mm groove cut 25mm inside the underside of the coping stone and runs all the way down the long edge.  It acts as a barrier against water reaching the wall and causing damage.  Rain water lands on top of the coping stone and drips down the side of the stone and underneath.  When the water hits the drip groove it falls to the ground, instead of reaching the wall.
