firstly, I had my drive and path block paved 2 years ago.. The job was ok but not perfect. The edging kerbs were left too high I wanted them to stick up by about 1cm but they are at least 6 cm above the block work. This makes cutting grass a difficult task.. How can i lower them my self without creating too much of a disturbance to the rest of the drive, Also after powerwashing the bricks I have washed the sand from the joints approx how much sand is required per SQ MTR to re sand the joints.
thanks
