Dig out a trench along the edges of the existing concrete driveway to a width slightly wider than the width of the pavers and a depth of 2 inches deeper than the height of the pavers.
Mix a concrete mixture, which is small gravel mixed with concrete, with water in a bucket or mixing barrel.
Pour the mixed concrete into the ditch to a depth of 2 inches. Smooth the concrete over with the smooth edge of the notched trowel.
Lay the pavers out starting closest to the start of the driveway. Drag the notched edge of the trowel over the wet concrete to create grooves that run parallel to the driveway.
Drop the pavers into position. Tap the pavers down with a rubber mallet until the pavers are flush with the surface of the existing concrete. Level the pavers so that the angle of the pavers matches the angle of the driveway. Tap each paver block until it's properly leveled.
