Decorative Stone

Q. How much decorative stone will I need?

Q. How do I prepare the ground before laying the decorative stone?

  • Edge the shape of the shrub bed required.
  • Spray off the area with a herbicide (Weed killer).
  • Lay down some weed barrier (Mypex).
  • Spread your chosen decorative stone to cover the Mypex as this will keep it in place.
  • Place your shrubs out and cut an X through the Mypex and plant.

  • Compact the 804 with a whacker or vibrating roller.

Paving Flags

Q. Is the process the same for laying natural stone paving as concrete flags?
A. Natural stone paving is laid on a mortar bed (Sand & Cement mix). Concrete paving slabs or bricks are normally laid on coarse grit sand.

Q. How do I lay Indian sandstone, Indian limestone or granite paving?

  • Firstly you need to have a compacted base.
  • Mix the mortar at a ratio of 5/6 part sand to 1 part cement.
  • Trowel the mortar on the compacted ground and lay the paving slabs on the mortar bed to your desired level. Some of our Indian sandstone comes calibrated which means it is cut to an even thickness therefore leaving it easier to lay.
  • Once completed grout your paved area with a jointing compound (grouting product).

Q. How do I lay concrete paving slabs or paving bricks?

  • Firstly you need a compacted base.
  • Spread coarse sand or grit across the area.
  • Screed to your required level.
  • Lay the flags or bricks.
  • Brush in jointing sand.


Q. How do I point my Indian sandstone, Indian limestone or other natural stone paving products?
A. There are different products available as well as different pointing techniques from the old fashioned sand and cement mix to the more popular pointing products on the market like Fuge and Botament. These products are considered to be clean and DIY friendly. The issues that may arise with sand and cement are unsightly staining on your completed paving. We would recommend using jointing compound for this reason.

Q. How do I joint concrete paving slabs or paving bricks?
A. Depending on the joint width normally kiln dried sand is used. It is brushed into the joints and swept off clean. If the joints are too wide you will need to use jointing compound. Kiln dried sand is only suitable for very narrow joints.


Q. How do I keep my paved area clean?
A. Keep the area free of debris. Use a pressure washer once or twice a year and treat the area with an algaecide like Patio Wizard or Moss Buster. Patio and sandstone cleaners are also available from Forge Paving Centre.

Q. Do I need to seal my paving?
A. No, however sealing products can help with regard to maintaining your patio or paving. We stock a wide variety of sealing products which can enhance your area and reduce the frequencies of power washing etc.
