Which Block Do I Choose?

It is always best to consult your nearest supplier or installer to make sure you have chosen the best type of block for your particular project. Please also note that your local supplier does not necessarily stock the full GreenLock range of products.

Each block in the GreenLock range has its own aesthetic appeal and engineered advantages. The choice as to which block to choose can be divided into four categories:

Unplanted Retaining Walls.

The GreenLock soil retaining blocks require no maintenance and are suitable to be planted or left unplanted. Each block creates its own distinctive design pattern. All GreenLock retaining walls are suitable to incorporate steps. The blocks are manufactured in grey and an attractive earthy color. Custom coloring can also be done on special request.

  • The S12 creates a wall which is either fluted or plain.
  • The R12 creates an aesthetically pleasing rockface finish.
  • The V12 creates a wave like appearance which can be varied in a number of ways.
  • The VR18 is ideal for the DIY market due to it’s size and weight.
  • The L9 and L7 lip blocks have been specifically desighned to be used for extreme high and strong walls

Planted Retaining Walls.

The S12, R12 and V12 provide the most cost-effective solution for a planted retaining wall. The V12 is the most cost effective solution and suitable for sites which require a number of corners and curves or more elaborate designs.

Sites with a number of corners and/or trees.

The V12, with its ability to turn angles up to 105º, will easily negotiate a site which requires a number of corners and curves. The angle markers on the block top surface ensure accurate and easy installation. Where trees need to be encircled, the V12 provides superior locking power combined with a pleasant visual appearance.

The VR18 is ideal for the DIY market

The VR18 retaining block has been specifically designed for the DIY market in mind. Due to it’s size and weight it is easy to handle and to install. It is ideal for the low garden walls, pathway edging etc.  The VR18 can be obtained in charcoal and sandstone. Because the VR18 is used for low walls there is no need to employ the services of a civil engineer. For building a wall of max. 4 rows of VR18 blocks (0.76m high), place the VR18 blocks on a horizontally stone bed and/or a well compacted soil surface. Compact the soil behind each block row laid and fill each block with any soil at hand or with top soil (compacting it slightly), if the blocks are to be planted. Use a “Set Back” for each row of blocks laid of not less then 70mm to 80mm. Make sure that the soil area on top of the wall is slightly higher then the top  block row, to enable storm water to run off and cascade over the wall front.

Sites which require increased reinforcement and stability.

All GreenLock retaining wall blocks are suitable for sites which require additional reinforcement, either due to height or angle restrictions. The blocks have the ability to be laid side by side as a double skin, triple skin or as many skins required or specified, so as to widen the base of the wall increasing the weight and thereby the stability of the wall. The R12 has the aditional ability to be ordered and used as a solid double block assembly before the blocks are split. Please note for multiple skin walls the blocks required per square meter must be adjusted acordingly.

GreenLock retaining wall blocks cover all aspects, from engineered structural walls to DIY walls and provide a cost effective, visually pleasing and structurally sound soil retaining solution.
