Retaining walls and in particular retaining wall blocks help in beautifying and adding value to your home. They are also the best option when it comes to protecting your home from flooding. Another alternative is concrete sleepers. Concrete sleepers in Brisbane and Gold Coast come in various colours, sizes, and textures resembling wood, rock, and stone.

Step to Install Concrete Sleeper Retaining Wall:

STEP 1:  BASE PREPRATION Clear and level your site where you plan to build the retaining wall. Please ensure you leave a minimum of 200mm behind the retaining wall area for backfill.

STEP 2: POST HOLES Starting from one end of the wall, mark a cross on the ground at 1.8mt Intervals.

STEP 3: AUGER HOLES Auger holes to a minimum diameter of 450mm and a depth as required determined by the height of the retaining wall, see schedule 1.

Step 4: Placement of Steel Posts Ensure post are level and spaced at 1800mm centres.

Step 5: Concrete Placement Concrete should be a minimum of 20mpa, check alignment of post before concrete sets. Allow a least 3 days before installing concrete sleepers. Set a concrete levelling pad between posts for the bottom sleeper to sit on. This pad can be below ground level if you do not wish to view the pad when finished.

Step 6: Concrete Sleeper Placement Slide the first sleeper into steel posts, check if sleeper is level, if not pack the bottom of the sleeper with concrete mortar to level. Place 90mm ag pipe, with sock, behind the bottom sleeper and connect to a legal point of discharge, slide the remaining sleepers into place.

Step 7: Backfill Drainage Material Place 20mm gravel, crushed stone or recycled concrete behind the concrete sleeper wall, plug the last 100mm from the top of the last sleeper with concrete or clay to stop any ground water from entering the rear of the concrete sleeper wall.
