Gardenwall Flushface is ideal in those designs which use contours and curves and is suitable for walls up to 1000mm high.

A range of colours are available to complement any garden style with the natural look of quarried stone and are suitable for DIY installation and are quick and easy to construct without the use of mortar joints or concrete footing.

The units are designed with an interlocking lip that creates a strong bond along the entire wall.

Installation Guide





National basic guide to wall building


Locate your wall

Mark out the ground where your wall will be located (either by marking with stakes and a string line or by marking a line on the ground with spray paint). Excavate trench then compact roadbase into trench to form a levelling pad.

Prepare the site

Place blocks side by side on the levelling pad using a string line along the back of the units for alignment. Level each unit side to side and front to back using your spirit level. Spend time making sure the first course of units is level, otherwise all ensuing courses and ultimately the entire wall will not be level.

Backfill and compact

Install an agricultural drain 150mm diameter behind your first course and surround with gravel (12-20mm sized gravel, e.g. blue metal). Shovel and compact your backfill (existing site soil) behind the drainage material. (Backfill consisting of heavy clays or organic soils is not recommended due to water holding properties).

Additional Courses

Sweep the top of the previous course clean. Place the next course of units in a running bond pattern (i.e. with the vertical joints from the first course units halfway across the second course units). Pull each unit forward until it locks with the nib on the unit below. Place the drainage material behind the second course of units. Stack units, placing drainage material and compact backfill for each block height layer until your wall is complete.

Fixing capping units

Place capping units, if required, on the top course. It is recommended that caps be secured using a construction adhesive such as liquid nails™. Some capping may require the removal of nibs from the top course of blocks.

Please consult with regulating council for local design requirements prior to the construction of any retaining wall. Councils in general require that retaining walls be designed and certified by a suitably qualified engineer where the wall is over 0.5m in height and/or where there is a surcharge loading, such as a driveway, house or other structure near the wall.

A carefully planned Cleaning & Maintenance program is the best method to keep pavers looking good for years to come.

Simple steps should include:

  • Regular sweeping to keep the pavers free from debris;
  • During construction, cover the paved areas to protect against damage;
  • Protecting against possible staining from mortar, oxides, cement and rust;
  • Do not stack pavers in a ‘criss-cross’ pattern as permanent hydration stains may result on corners;
  • Do not use a high pressure cleaning apparatus.
  • Prior to removing stains, we suggest that the type of stain be carefully assessed before action proceeds. Incorrect assessment can lead to the stain being more difficult to remove. If the stain
  • cannot be accurately assessed, then we would recommend that a trial process on a small portion of the stained area be undertaken to determine the most appropriate action.

A guide to Concrete Paver common stains


This is a salty deposit on the surface of pavers which appears as anything from strong, powdery, white blotches through to a fine white haze that can make pavers or blocks look “faded” and is generally the result of a chemical reaction that takes place as concrete cures. Efflorescence may also soak into pavers or blocks from salt deposits in adjacent materials such as bedding sand, joint sand or soil.

Rain will generally dissolve efflorescence and gradually wash it out of the paver or block over time. Stubborn patches may require cleaning with a stiff bristled nylon brush or colourless plastic scouring pad (do not use deeply coloured or metallic brushes or scourers as they will leave marks). It is important to brush away powder residue and then rinse and brush the area thoroughly with clean water after breaking up the efflorescence otherwise it may simply soak back in and re-stain the area again. If stronger methods are required, reputable sealers from manufacturers such as ENVIRONEX and Drytreat and other efflorescence cleaners are available through good Landscape Supply stores.

Cleaning & Maintenance – Moss, Mould and Leaf Stains

Soak the area with a domestic bleach or a solution of five parts water with one part pool chlorine. Leave for ten minutes then gently hose down before the solution dries.

Cleaning & Maintenance – Sealing of Concrete Pavers

For maximum protection, National Masonry™ recommends that all pavers should be sealed with a quality penetrating sealer following installation. Please check with a qualified tradesperson for advice on this process. National Masonry™ does not accept liability for stained or damaged pavers once laid.

WARNING: Hydrochloric acid is NOT recommended for use with concrete pavers as irreparable surface damage may occur.
