Step 1 a. Mark out the realm to beaved and take away all of the topsoil or current surfacing to a depth in order that the completed degree is no less than 150mm under the damp proof course of any adjoining home or constructing. If the realm is flat it will likely be obligatory, for drainage functions, to create a slight slope through the excavation, dropping 25mm over 1 met throughout the width (1:40) and 25mm over 2 meters alongside the size (1:80).
B. Compact the excavated space with the plate vibrator, digging out any comfortable spots and filling them with sub-base materials. C. Set up floor water drainage channels if required, ie if the paved space slopes in the direction of the home / constructing or another place the place water run-off wouldn’t be welcome. Recessed manhole covers must also be put in at this stage if required.
Notice: Completed degree of paving must be approx. 5mm above any drain level.
Step 2 Set up all edge restraints, whether or not kerbs or edgings, by setting firmly in concrete to appropriate ranges.
Step three Lay the sub-base materials inside the edge restraints and compact it firmly with the plate vibrator; Relying on how nicely it compacts, you could have to go over the entire space between 5 and 10 occasions. It’s important that this sub-base is agency and to the suitable degree and if there are any voids, fill them with sharp sand.

Ideally, the lighting ought to illuminate all sides of the drive.
Step four Unfold the sharp sand to a depth of 50mm, compact it with the plate vibrator and unfold an additional 15mm of sharp sand over the realm as a free screed. Appropriately degree the screed with a inflexible piece of timber or screed bar drawn alongside information rails.
Step 5 Lay one course of blocks on the sand alongside all the sting restraints. They could be laid lengthy methods towards the sting ('a stretcher course') or with the brief aspect towards the sting ('a header course') relying on private choice.
Step 6 Lay the blocks hand tight solely, with a joint hole of 2-5mm, beginning in a single nook and on the backside if there’s a slope.
A. Randomly combine and lay blocks from no less than three packs to make sure even distribution of colour and texture.
B. If laying in herringbone sample pull a string line throughout the realm at 90 "or 45", as acceptable, and lay the blocks alongside the road. To begin a herringbone sample both put stretcher blocks alongside the road with one nook towards the sting restraint and fill within the gaps later with lower blocks, or use Bishop's Hats, which sit flush towards the sting restraint and provide the angle to work from.
C. Items smaller than one quarter of a block must be prevented the place attainable.
Step 7 Sweep the realm totally after it has been laid – significantly if a block cutter has been used – to take away all chips and fragments. Then verify to make sure there aren’t any broken blocks; If there are any, that is the time to switch them.
Step eight Compact the entire space with two or three passages of the plate vibrator.
Step 9 Sweep jointing Sand over your complete space, making certain it will get proper into all of the joints between the blocks.
A. Jointing Sand shouldn’t be utilized in moist climate as moist sand won’t fill the joints correctly and will stain the floor of the blocks.
B. If there’s a recessed manhole cowl, care must be taken to keep away from any sand getting in between the duvet and the body.
Step 10 Vibrate the entire space once more to drive down the Jointing Sand and fill any gaps which seem within the joints. Go away any surplus sand on the floor for the wind / rain to scrub into joints. Alternately sweep off the floor and re-sand if obligatory.
