Garden Retaining Wall Project

An uneven garden can be arranged into smaller terraces and green spaces using retaining walls. But these walls play more than one role. They are nice decoration, especially of you use blocks that fit the overall design of your garden, but they will also create healthy garden spaces by improving water drainage and reducing erosion. So when thinking about retaining walls, you must imagine a sturdy and firm structure, solid enough to retain all the soil behind. A garden retaining wall is not difficult to build and it can be looked at as a home-improvement project that can be completed over a weekend.

Prepare the site

First of all; you should decide where you want to building retaining walls. You can use stakes and strings, or simply a garden hose, to lay out a line. You make shape you want, from a rectangular to a random outline; whichever suits your garden best. Level the surface to be enclosed to ensure an even height. Before you start digging, make sure there are no cables or pipes underneath.

Once you have outlined your retaining wall, use a shovel to dig a trench along the line you have laid out. The trench should be a little wider than the width of your wall. Try to dig the trench as level as possible. It should be deep enough to cover the first layer of blocks at least one inch. You should also take into consideration that there will be a four to six inches of paver base underneath the first layer of blocks.


Tamp the soil on the bottom of the trench using a soil tamper. Add rock dust or patio paver base to the bottom of the trench. Make sure you add at least 4 inches. Rake the paver base and make sure that the remaining trench area has a uniform height. If there is any uneven area, add a little more paver base, or take some away by raking.

Build the retaining wall

Place the first layer of blocks starting with the most visible edge of your wall, or with the edge that is closest to any other building in your garden. If your retaining wall is rectangular, make sure that the blocks line up perfectly. Use coarse sand and a rubber mallet to level the first layer of blocks. You may need to cut some blocks using a mason’s saw in order for them to fit the width and length required for the first layer. Use gravel to fill the space in between the blocks and the walls of the trench. This will offer a great support.

Once your first layer is completed, continue by adding more bricks. Follow a staggered pattern so that the layers will seem offset. If the edges are straight on the ends in your current layer, the next layer should start with a block cut in half. Lay out the layer before applying the adhesive to see how it looks. When you are fine with the pattern, apply adhesive to the bottom layer an fit the next level of blocks. Press down to make sure that they are tightly secured. Add layers until you reached the desired height.
