Walls, Edging & Stepping Stones
Edging
All edging range can be laid directly into the ground. However for stability we recommend a more permanent method of fixing.Dig out a small foundation trench to the required length, 100mm deep and 150mm wide. Fill and level with a mix of 1 part cement 4 parts coarse aggregate to 2 parts building sand.

As soon as the foundations have cured, the edging should be bedded by gently tapping the top edge with a rubber mallet into a mortar bed of 1 part cement to 4 parts building sand, ensuring each edging unit is aligned and level. Back fill the reverse face of the edging with the same mortar mix “haunched” with a 45 degree wedge of mortar to a height that will be concealed by the finished surface.

Laying Stepping Stones
Evenly space the stepping stones as a pathway or across the lawn or border.

Cut away the surrounding turf using the stepping stone as a template to a depth of approximately 75mm. Infill with a sharp sand to the depth of 35-30mm or use a weak semi dry mix of 1 part cement & 5 parts sand. Place stepping stone and tap down gently with a rubber mallet so that it sits just below the level of the lawn.

Walls
As a benchmark the foundation should be dug to a depth between 25% to 1/3rd of the wall height or minimum depth 100mm. Start by stripping the topsoil, dig to firm ground and lay level concrete foundations. The foundations width should be three times the width of the wall.

A recommended foundation mix would be 2 parts building sand to 4 parts coarse aggregate 1 part cement. Stretch a building line between the ends and build one course at a time, using a spirit level regularly checking for accuracy, diagonally, horizontally & vertically.

Spread mortar (4 parts building sand to 1 part cement) evenly over the foundations and over the blocks, in each course as you lay them, using a trowel. The mortar should just exude from between the joints and surplus mortar is taken off with the trowel.

Remember to fill the vertical joints as you go by applying mortar to one end of the block before positioning it adjacent to the previously laid block. Each block should be laid in a stretcher bond using half blocks at the end of each alternate course. Using a pointing trowel, smooth and finish the mortar joints. Finish with Coping if required.

Kindly note for retaining walls higher than 600mm or any wall built over one meter high, professional advice should be sought prior to construction.
