A Practical Guide to Laying Paving

 

Base Preparation

 

1) Remove topsoil from the area to be paved.

 

2) Base materials may consist of granular materials (Crushed aggregates or limestone screenings) to be placed in a 6" layer. The thickness of base will vary with type of soil subgrade and climate, colder climates may require thicker bases.

 

3) The base layer should be thoroughly compacted with enough water to aid compaction, increase density and also control dust.

 

4) Once the desired compaction has been achieved place a 1/2" bedding layer of loose sand on top, ensuring that the base is level by using a string line or screening board.

 

5) Patios should be laid with slope to drain off rain water. This slope (away from buildings) is normally a drop of 1 " for each yard in length.

 

 

Laying Paving   1) Choose the design that you wish to lay, then starting in a corner carefully place the first slab in position and gently tap down using rubber mallet.   2) The bedding layer of loose concrete sand allows for leveling the surface of each slab which may vary from piece to piece due to their texture.   3) Slabs may be laid with up to 1/2" joints and filled with dry sand on completion of installation.   Under no circumstances should a mechanical compactor be used directly on the slab surface

 

 

Laying Circles and Other Features

 

1) To lay a circle, follow the paving laying instruction left, except start at the center of the circle and work outward. Dry lay each ring before fixing into position.

 

2) Where a circle is laid as a feature within a paved area, use the corner accessories to square up to the paving. You may want to lay a few courses of paving before you start your squared circle to avoid cutting at the edges. When completed, sweep masonry sand into joints. (Polymeric sand is recommended) Do not use vibrating plate on surface.

 

 

 

Laying Chelsea Cobble

 

1) The main units have irregular edges to give the impression of a number of cobbles placed onto one slab. Rotate the main units to randomize the cobble effect. Use the wavey edges to place the slabs together. If you require a squared off effect use the side and corner units accordingly. Fill the paved area to make the joints appear invisible.
