Laying Paving.

Paving can be directly laid onto a 50mm layer of sharp sand on top of well tamped soil. It is strongly recommended that paving is laid on a bed of firm foundations.

Always dry lay first to make sure you are happy with the pattern and as a check on the size of the finished area.

Allow approximately 10-15mm joints for pointing; more for paving with fettled edges. Ensure that water cannot collect beside buildings by allowing a slight fall away to a convenient place.

Landscape fabrics work by suppressing weed growth whilst allowing moisture nutrients to pass through its membrane. Landscape fabrics can be laid on top of a well compacted sub-base prior to bedding down the chosen paving.

1. Allow at least 150mm below the damp proof course and dig down another 150mm for the paving/fountain. This applies to the whole area to be paved.

2. Cover the entire area with a semi-dry foundation mix of 6 parts all-in ballast: 1 part cement to a minimum depth of 75mm. This should be firmed with a piece of timber. Remember to allow for the thickness of the paving stones on the mortar bed.

3. Lay the first paving stone in the corner of the area to be paved on a bed of mortar (3-4 parts building sand: 1 part cement).

4. Tap down the center of the stone with a wooden or rubber mallet to the required height.

5. Repeat, ensuring that the paving is level using a spirit level and the joints are evenly spaced.

6. When your paved area is completed, point the joints using a semi dry mortar mix - 3 parts building sand: 1 part cement. The mix should not be too wet or too dry.
