Build in 4 easy steps...

Step 1Dig a level trench 75mm (3”) deep and 180mm (7”) wide. Fill in 75mm (3”) of compactable aggregate and consolidateby tamping into place.

How to build walls...

Step 2Install the base course of block on the aggregate, tamping and levelling into place. The raised rings on top of the blocks lock subsequent courses together.

Step 1Prepare a foundation pad by digging a 600mm (24”) square, 100mm (4”) deep hole. Fill in 100mm (4”) of compactable aggregate and consolidate.

Step 2Place 4 corner blocks with the long sides facing out. Square up the blocks, tamp into place and level.

How to build piers...

Step 3Continue stacking courses of blocks in the pattern you choose until the desired height is achieved. Offset the vertical seams on each course.

Step 4Finish the wall with wall caps. Secure in place using a concrete adhesive.

Step 3Continue stacking courses, alternating the pattern to offset the vertical seams until desired height is achieved.

Step 4Finish the pier with the two piece pier caps. Secure in place using a concrete adhesive.

Tip...Taller walls will require some added stability. Try one of these

strengthening techniques:• Design with serpentine curves or 90° corners• Glue courses together

• Drop metal fence poles through the small holes in the

blocks and drive into the ground

Use corner blocks to end each course

Step downs...

Building wall panels between piers adds strength and creates a traditional effect.

Combining walls and piers...

Step 1: build the first pier

Step 2: install base course of wall using split blocks and full blocks

Step 3: build the second pier

Shaded blocks represent the split blocksNote: Plan for some splitting and fitting. Place the split sides against the pier blocks to make a tight fit on each course. Alternate split blocks per course.

Build the panels using the Dublin or York blocks, or combine them to create unique patterned walls.

Determine the height of your wall in courses - each course is 150mm. (6”) high. Measure the total length of the wall or walls, and use the chart below to find the number of Dublin blocks you will need.

Ordering materials...

Note: Order extra caps or corners for each step down.

Walls can be “stepped down” two ways.

or try adding an extra wall cap at the end of each course

(to switch from Dublin to York blocks, simply double the number in the chart)

Building curved walls is simple. Using the York block, stack two courses at a time to create a perfect 1m (40”) curve. You will need 27 York blocks to build a complete full circle.

Build curves...

Locate the blocks with the splitting notches. Using a hammer and chisel, lightly tap around the entire block to create a scored line. Then strike the chisel with more force to break the block. Be sure to wear safety goggles.

Splitting blocks...

Techniques...

Break a Dublin end-split, or a York centre-split, along the splitting notch and place the split end against the corner block to make the 90° corner.

On the next course, reverse the position of the split piece and the corner block. Continue alternating each course.

Finish the corner with wall caps. Secure in place using a concrete adhesive.

Building corners...

On straight sections the Dublin and York blocks can be alternated to create unique patterns
