There are 2 methods you can employ as the bed for block paving, one, you have fully compacted sand making the sub base and the laying coarse much firmer, achieving a much flatter surface. To achieve this you need your sand approx 10 – 15mm higher than the finished screeding height, this surplus sand is screeded off to the correct height and then you lay your block paving.
When you go to choose your block paving, you will want to find a color that matches the rest of your house. The pavers who are professionals at paving will be able to give you ideas of what type of color should go in front of your home, and which one will stand out the most when it is placed in.
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.
If you want to seal a driveway or parking lot that is several years old and has already begun to deteriorate, the paving contractor must first repair the damaged asphalt. This may involve filling any holes or cracks in the pavement, as well as smoothing out rough areas. It’s also a good idea to clean up any oil stains before applying sealcoating, as once they’re sealed in, those stains are permanent. In general, you should apply a new coat of driveway sealer every two to three years. Resealing and minor repairs will almost always be less expensive than having to completely replace the pavement.
