Using a tight string line to get the screeding rails to the correct finished height prior to screeding the sand, check for level or falling towards any drains, a 1:60 fall is required, that’s 1” in height to 60” in length minimum fall to ensure any surface water drains into your drainage system or soak-a-way.
Traditional gravel or pea shingle driveways: These were once only for the very wealthy. They were introduced as a security measure. The idea being that when a vehicle or person made contact with the shingle, the noise would alert the household to the intruder.
Having a sealed driveway or parking lot surface has benefits far beyond the money saved on re-paving. For starters, the smooth, sealed finish will be easier to clean than cracked, stained asphalt, enabling you to keep your property looking its best. Even more importantly, sealed pavement is safer to walk and drive on. Large cracks and holes can pose a tripping hazard for individuals of all ages.
Two Set up your level line. You will need to knock 2 timber or steel pins into the ground, one at the house end of the driveway and the other at the pavement side. Next, attach a tight builder’s nylon line at what will be the finished height of your block paving, this line should be approx 10mm higher than the pavement and 150mm lower than the damp proof course to allow for final compaction of the block paving.
