Paving Storage

Store your paving on-site in close proximity to the project area.

To avoid damage, if you have to remove them from the A-Frame pallet before using, carefully stack paving on edge raised off the ground on timber battens.

Remember to select paving from different packs as you go along, this enhances colour blending and will help to alleviate any variation in colour that may occur between packs.

Base Preparation

A layer of PAP7 or equivalent should be spread over the excavated area, raked level and compacted using a roller or plate compactor to a depth of 50mm. When choosing the base aggregate be sure to choose sharp aggregate with no holes; scoria-type aggregates are not suitable and can cause discolouration of the paving.

Preliminary compaction can be made by placing a plank over the PAP7 and walking over it; then thoroughly compact the whole area.

If laying onto an existing concrete pad, it should be clean and free from dirt, grease, mould, paint, etc to ensure a firm bond. It is vital that the concrete pad be dampened to prevent absorbing moisture from the mortar and causing a weak set.

Mortar Bed

On a mixing board make up a slightly wet mortar mix of 1 part cement to 5 parts building sand approximately 25mm thick working in areas of 1-2 m2 at a time.

Starting from a corner or straight edge, trowel one mortar bed, placed slightly higher than finished level of the paving. This allows for easy alignment and adjustment for required finished surface level and it also enables any variation in thickness of each individual slab to be taken up.

Laying

Wetting the back of the pavers will keep the mortar workable and give better adhesion. After laying the first slab, place another bed for the next slab and also lay a strip of mortar where the next joint will be.

With the trowel, draw and butter this mortar to the side of the slab, thus minimising pointing afterwards.

Paving Levels

With a rubber mallet, tap each slab down to the required level, keeping a piece of softwood between hammer and slab.

Continuous checking of levels and falls should be ongoing during the laying process and should be taken across the top surface profile of a number of slabs.

Use string lines to ensure rows are straight.

Spacing & Pointing

Before proceeding too far, it is important to equalise slab spacing, gently shuffle the slab with a twist of the trowel until the joints look even.

Small pieces of 5-7mm thickness of hardboard or ply are ideal when laying paving (these should be removed before pointing).

After laying, do not walk on the paving for at least 24 hours. Thereafter joints may be pointed.
