There are plenty of gardening ornaments that can be done using hypertufa and one of them is a retaining wall for your garden. A hypertufa retaining wall is ideal since they are able to resist the extreme winter temperature, for up to -30°C. They are also aesthetically pleasing as they can give your garden a more natural stone appearance. Although hypertufas are usually light, a number of products can be included to ensure they are more heavier and tougher for the purpose of creating a retaining wall.
To make a hypertufa retaining wall, you should adjust the basic recipe that is regularly used: mix 2 parts Portland cement, 1/2 part coarse sand, 2 parts perlite, a little bit of nylon fiber mesh, and 1 1/2 parts peat moss. The coarse sand will make your hypertufa heavier compared to the typical and the fiber mesh will enhance the structural integrity of your creation, so that it is ideal for a retaining wall.
The subsequent procedure is to locate the mold for the blocks that will be used for your retaining wall. You need to take into account the area where you will be putting your retaining wall so that you will have an idea of how big is the mold that you will would need. You can use shoe boxes as molds although if you think that they are not suitable, you can always produce your own mold using styrene foam used for house insulation, wood, or cardboard. Additionally you can dig block-shaped holes in the ground and cover them with plastic for your mold. Just remember that you’ll want to have as many molds as possible. You’ll need lots of blocks for a retaining wall and it requires a lot of time to be able to cure a hypertufa so it is perhaps a good idea to produce all of the required blocks in one batch.
After your hypertufa blocks have been totally cured and are completely ready to be placed, you need to create a mortar mix to hold them together. For that you will have to combine 1 part Portland cement, 1/2 part peat moss or black potting soil, acrylic fortifying base, 1/2 part clay soil with clods broken up, 2 parts builder sand, and water. Then line up a layer of your hypertufa blocks, put on the mortar mix on the top of the layer, and repeat the process until you have created the retaining wall.
