As our walls and seating were laid over existing paving, the blocks could be laid directly onto the existing pavers. Otherwise, concrete or block footings would be required. Step 1 Mark out wall locations. Step 2 Mix up a fairly stiff mortar of 4 parts brickies sand to one part cement. Step 3 Lay end and corner blocks first, ensuring that they are level and plumb, then set up string line and lay blocks in between on a good bed of mortar.
Butter ends of blocks with mortar and place blocks onto bed and up to next block.
Tap blocks into position on mortar taking care not to overwork them. Strike excess mortar from the finished joints with the edge of the trowel. Step 4 Continue subsequent courses as for step 3. Step 5 Where capping is required on garden walls, lay on same mortar mix, setting end pieces first and laying in between. As our paving was laid over existing paving and undisturbed subgrade, there was no need for a compacted roadbase layer under the paving sand.
