If you have a sloping block that you want to level out, and you need a retaining wall 600mm or under to do it, a timber retaining wall could create loads of extra space. The edging keeps grass roots from creeping into the stone wall, and the mulch provides a mowing track for the lawn mower wheels. Adjust by lifting the stone and adding more gravel or digging deeper as necessary. Lay landscape fabric against the back of the wall before backfilling to keep dirt from washing out through the stone. All retaining walls encounter the force of water, whether it’s from heavy rains or some other unforeseen event. Brace each post as shown in the drawing below using 75×50 (2×3) treated lumber for both braces and pegs (rip 150×50 (2×6) retaining board in half to get the braces and pegs. With this information you can build yourself a great new retaining wall that will last.
Builders will still need to dig a trench and pack down a layer of sand first, but they can easily connect the blocks together to form the wall. Retaining walls made from timber, logs or sleepers not only look good, they’re quite simple to put up. As long as you follow a few basic rules, you’ll have a great looking wall that’ll last for years. In the absence of such an indication it becomes necessary to examine the physical evidence in order to establish the position of the boundary in relation to the wall. Despite the size of the stones, the builder has delicately sloped the wall to help resist outward soil pressure.
A strong wall features well-compacted base material, compacted material in front of the wall to prevent kick-out, and stepped-back materials. What started out as a simple idea to move the existing cedar beds resulted in us having a very pretty – and useful – raised garden bed for vegetables! A party fence wall is therefore a wall that stands astride a boundary, and the boundary will normally run along the centre line of the wall. He was using larger bricks and ran 2 rows (2′ vertical) at a time, then back filled with sharp gravel/fill and packed it down, then placed a metal mesh/grid-work over it.
After doing this, saw off the excess wood and reinforce the right-angled corner with a piece of hardboard. The first step was leveling the ground where the stone walls would be. My husband used a tamper for this. If those are the rocks you have, buy some sheets of plywood, build a simple but strong form to support same and make a concrete ‘rock’ wall. Brace all the posts temporarily in position so that they are vertical when viewed from the front, but slope towards thebank at 1:10.
To make it easy for you, Aussie Concrete have created the Ridgi DIY reinforced concrete retaining system, which has been specially designed for low-load retaining and garden beds with heights below 900mm. This kinetic design is made by applying a veneer of colored concrete over a solid block wall. I recommend having a small trowel handy and as you lay the bricks you can either add or remove soil to keep them level and straight. The reason is that the stones placed on top of these sloping stones will eventually slide down off the wall.
Dry walls can be made of broken concrete, old tires(makes a great retaining wall to protect the 1964 Chevy pickup on blocks, behind the chicken coop) , logs(don’t last long), concrete block (what’s the point?), rocks, railroad ties (see logs) and almost anything else you can stack. By building the wall on a backwards slant, you counteract the effect of gravity.

Check with your local planning department – many building codes require a permit for a retaining wall, and may have a height limit on a do-it-yourself wall project. Backfill the trench with some of the dirt you excavated earlier and tamp it down well to ensure the foundation of the wall is solid. When building walls to retain soil, the height of the wall should be no more than 4 times the thickness.
To determine how many blocks you’ll need per row, divide the total length of the wall by the length of the block. A simple retaining wall that creates a raised gardening plot filled with petunias, black-eyed susans, and other members of the daisy family. Angle the borer to allow for the slope of the poles 1:10 (so the posts lean 100mm for every 1m of height).
Or if there is mature lawn under the area where the wall will be placed, which has been there for a at least a few years and slopes away from the face of your wall. There’s no impervious soil, so the water heads south, slowly waterlogging and increasing the weight of the soil packed behind the wall. The architect has combined with the engineer to design wall that is both structural and aesthetic in this garden design. Most free standing walls are supported by piers – towers of bricks attached to the side of the wall to provide additioNAl strength.
You will find that our solutions are cost effective and flexible for a broad range of wall projects large to small. This wall is about 30 years old, a little cracked, but still solid, again a wide wired base. The foundations need to be at least 3 times the width of a half brick wall (i.e. 34 cm/13.5 inch) or at least twice the width of a one brick wall (i.e. 45 cm/18 inch). Please apply mortar on the top of the breeze blocks and place the blocks on for the second row.

Avoid having downspouts pointed at the retaining wall and, if it’s against the house, keep soil and mulch well below the siding. Timber design options are also really limited, as they only come in straight sleepers or circular logs.
