Step 1: Dig a shallow trench, level and place 100mm of crushed rock in the bottom and compact.
Step 2: Spread and level 25mm of course sand as a bedding layer. Place the first layer of Miniwall units onto the sand and tap with a mallet into place. A string line is essential for building straight walls. Ensure that each unit is level from front to back and side to side.
Step 3: Stack Miniwall units along the length of the wall to a maximum of 3 rows, ensuring that each row is offset to the one below. If the wall is acting as a small retainer fill immediately behind the wall with 200mm of crushed rock.
Step 4: Before applying Minicap, place some construction adhesive either side of the interlocking nodules on Miniwall. Position Minicap and press firmly into position.
Freestanding Walls: As Miniwall is stacked vertically and both the front and back of each unit is finished with an attractive split stone texture, both sides of the wall may be left exposed. In this situation it is recommended that construction adhesive be used between the upper two courses of the wall.
S-Curves: To build a solid wall which changes from an inside curve to an outside curve a half unit will be required every second course. Use a Minicap and perform the cut with either a masonry saw or splitter.
CURVE RADIUS
Minimum radius for inside curves is .435m and .615m for outside curves. With Miniwall's tight radius, cumbersome corner units are not required - simply round the corner off. Half units if required can be split or cut from full units using a masonry cutter.
 Here's a hint - 21 units form a circle!
MAXIMUM HEIGHTS
Miniwall is suitable for walls up to 500mm high (4 rows) where there is no surcharge loading.
A surcharge loading applies when:
• Wall is supporting a driveway or other load.
• Greater than 3:1 slope above the wall.
• Another retaining wall above the wall which is less in distance
behind the wall than double the height of the lower wall.
