FIXTURES & FINISHES
crushed concrete inside of the edge restraints, rake to the desired level in layers of 50 mm, then level and compact using a vibrating plate. The roadstone should be at least 160 mm thick after compaction. We’d recommend passing the vibrating plate over the area at least seven times to ensure it is thoroughly compacted.
SCREEDING
Get the driveway wrong and the whole image of the front of a property becomes unbalanced
position, haunch the back of the units so that the concrete reaches halfway up the rear of the kerb.
SUB-BASE Lay MOT Type 1 Roadstone or Type 1
Once this has been done, apply a layer of slightly damp sharp sand to a depth of 40 mm and compact with the vibrating plate. A second layer of sharp sand to a level of 20 mm should then follow on top of this. Using the string lines, screeding rails and straight edge, this second layer of sharp sand needs to be levelled to the correct falls.
PAVING INSTALLATION
Always begin laying block paving from the bottom of a slope, preferably starting from a right angle or a straight edge. Place the blocks on top of the laying course ensuring blocks are around 10-15 mm above the desired finished level. Continue with your desired pattern while making sure that you are using blocks from between three to five packs at once in order to minimise any colour banding. When all the full blocks have
been laid, you will need to cut a certain amount of blocks to fill the smaller gaps. This can be done by using either a block splitter or a diamond disc saw. A handy tip here is to avoid cutting a block to less than a third of its original size.
FINISHING TOUCHES
Once all of the blocks have been laid, sweep the drive thoroughly to make sure that there is no debris left on the blocks. Then apply kiln dried sand and sweep across the whole of the drive, making sure that this sand falls down between the joints of the blocks.
Having completed this, the drive needs compacting with the vibrating plate. We recommend a neoprene faced or rubber sole plate on vibrating plate compactors to reduce scuffing. You will then need to sweep more kiln dried sand over the drive and compact again. Keep doing this until all of the joints are full of sand. Once this final task has been
completed, the driveway is ready for use. However, make sure all work on surrounding areas that vehicles will pass over is also ready for use to prevent any staining or material transferring to your new driveway as a result.
