How To...

Planning:

Take your time to research the different types of paving slabs and estimate quantities and costs.

Allow 150mm below the damp course of your house then excavate approximately 200mm for the foundations, laying bed and slab thickness.

Foundations:

To prevent later movement of laid paving a good foundation is essential. 100mm deep of compacted scalpings (crushed limestone, pink in colour) or a lean concrete mix of ballast and cement mixed 6 parts ballast to 1 of cement is ideal.

Laying:

Ensure a slight fall when laying to take surface water away from any buildings. We recommend laying paving on a full bed of mortar, mixed 6 parts sharp sand to 1 part cement at a damp and workable condition without being overly wet and runny. Push the slab down by hand to roughly the level required then gently tap into place using a rubber mallet ensuring the paving is level using a spirit level. Allow a gap of 10-15mm or whatever the manufacturer suggests for the type of paving you are using between each slab. Do not walk on the paving until the mortar has set.

Pointing:

Some slabs can be butted together and don’t require pointing. If they do, once the slabs are laid pointing ties the whole area together. The joints should be filled with a damp 3 to 1 mortar mix which should be trowelled between the slabs and firmed in. Take care not to stain the slabs when doing this. Smooth off using a pointing tool (a piece of firm hose would do). Alternatively use a jointing compound.

Cutting:

At the planning stage try and keep cutting to a minimum. Should you need to cut slabs powered disc cutters are available from local hire shops. Make sure you follow correct safety procedures and obtain instructions as these are potentially dangerous machines.

Because of its superb durability, porcelain is low maintenance and requires no additional treatments such as sealants during installation. We recommend laying porcelain with a traditional method on a full bed of mortar over a compacted sub-base. Use a slurry primer on the underside of each slab to create an adhesive seal between the slab and mortar bed and ensure a minimum joint width of 5mm. If making cuts, you will also need a diamond blade for porcelain. For full details on laying method and additional products you may need, see our porcelain product guide.

Installing on a hard (bound) surface such as concrete, tarmac, macadam, asphalt

  1. Ensure surface is clean and free from debris
  2. A slight fall of 1:200 to assist drainage is preferred, otherwise a few drainage holes in the concrete are recommended
  3. If laying on top of paving slabs or decking it is recommended that an underlay is used to prevent the pattern of the slabs/decking from showing on the surface of the grass.
  4. Spot glue or lay loose and fix around the perimeter.
  5. For a wooden base it is best to staple.

Installing on unbound surfaces

Well compacted unbound aggregate bases are ideal and if laying an artificial lawn from scratch this is highly recommended, but any unbound surface that drains and is stable and fairly level is satisfactory.

  1. Remove soil to a depth of 100mm
  2. Compact and level the ground with a compactor plate or roller
  3. Option of fixing down weed membrane
  4. Lay sub-base, such as scalpings to a depth of 25-75mm, level and compact with a plate compactor or roller. If you choose a timber fixing for the edge of the grass, fit using tantalised timber and fixing spikes
  5. Add a thin layer of fine aggregate (such as sharp sand) over the sub base and compact again
  6. Roll out the grass over the base and ensure the directional pile runs the same way if there are multiple pieces. Trim to size with a sharp knife and secure any joins

If you are trying to keep the cost down you can just compact existing soil and cover with a thin layer of compacted fine aggregate (sharp sand or 2-6mm limestone). However you must remove the existing lawn or unevenness will soon become an issue.

a). Sand filled grasses should be spread over the base and filled with the kiln dried sand and brushed in. The weight of the sand holds the carpet in position.
b). Products not requiring sand infill are fitted under tension and are fixed around the edgings by either;

  • Butting up against an existing wall or kerb
  • Fixing to a tanalised timber edge board
  • Placing the edge of the grass under paving stones
  • Burying the grass edge under adjacent natural turf

Making joins in larger installations

All cuts should be made with a sharp knife. Joins are made by sticking the underside of the artificial grass to a special seaming tape with the recommended adhesive. Adjacent panels of grass should be laid together ensuring straight cut edges are butted close together. All of the grasses have a directional pile so make sure that all panels are running in the same direction. The edges should then be folded back and the seaming tape laid, shiny side down, centrally along the joint. Apply beads of adhesive to the tape and spread out to create a solid think line about 10mm wide. The carpets can then be folded back down and pressed into the adhesive.

Maintenance

Remove any debris, particularly leaves and pet droppings, otherwise they will compost into the surface and allow moss to grow. Sweep or in dry conditions it can be vacuumed with a domestic appliance or leaf blower. Do not vacuum sand filled grasses! If moss does form treat with a moss killer and sweep away. For best results use a stiff brush. Remove any weeds by hand or spot spray with weed-killer. Please note that artificial grass is a plastic material and can be subject to damage from heat sources such as barbeques and refracted rays from glass table tops.
