Basic D.I.Y Laying Guide
- Store your Paving Worx paving on site in close proximity to the project area. Remove packaging from paving. To avoid damage, if you have to remove them from the pallet before using, carefully stack paving on edge raised off the ground, back to back, face to face on timber battens. Remember to select paving from different pallets (if you have more than 1) as you go along, this enhances colour blending and will help to alleviate any variation in colour that may occur between packs.
- A layer of crusher dust (aka. pap7/fines) equivalent spread over the excavated area, raked level and compacted using roller or plate compactor to a depth of 50-60mm preliminary compaction can be made by placing a plank over the crusher dust and walking over it then thoroughly compact the whole area.
- In a wheelbarrow, make a slightly wet mortar mix of 1 part cement to 5 parts of building sand enough for 2-3m2 at a time. Starting from a corner or straight edge, using a spade place 5 spade fulls for each paver, this needs to be sligher than the desired height so that it flatens and spreads. This allows for easy alignment and adjustment for required finished surface level and it also enables any variation in thickness of each slab to be taken up.
- After laying the first slab, place another bed for the next slab, and so forth. DO NOT PLACE PAVERS HARD UP AGAINST EACH OTHER WHEN LAYING, make sure there is at least a 1-2 mm gap at the base of each paver. This is then filled with mortar afterwards (aka. pointing)
- Before proceeding too far, it is important to equalise slab spacings as best as possible, gently shuffle the slab with a twist of the trowel until the joints look even. Stand back and look down the line to ensure none look out of place or are crocked. Use temporary spacers – small pieces of between 10-20mm thicknesses of ply are ideal – when laying these pavers (these should be removed before grouting). Use string lines to ensure rows are straight. After laying, do not walk on the paving for at least 24 hours, thereafter the joints may be grouted.
Laying onto sand
- There is another option for laying paving; Laying directly onto sand, this may be a bit quicker but doesn’t give the same results as the mortar bed option but can still give good results if done properly.
- The base coarse of crusher dust is prepped the same as the mortar option but a fine 10mm screed of un-compacted sand is used, the pavers are then laid and leveled on this. Use similar methods as above when laying.
- To fill the gaps between the pavers a sweep in type grout can be used (Or Mortar pointing, as above), eg PAVETIGHT. With the sweep in grout it is best to fill gaps directly as much as possible then smooth out with a broom, instead of emptying the bag in 1 corner and then sweeping to the other.
- When in the gaps and leveled a misting of water is applied. It is critical to not over water as this washes the glue component out of the sweep in grout out, just enough to fully dampen to the bottom of the gap is all that is needed. Most sweep in grouts have weed resisting properties but they can still appear, the sweep in grout may need to be touched up in years to come.
