Hypertufa Retaining Wall
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 tolerate the severe winter temperature, for up to -30Â°C. They are also eye appealing as they can give your garden a more natural stone appearance. Although hypertufas are generally light, several ingredients could be added to ensure they are more heavier and tougher for the purpose of creating a retaining wall.
To construct a hypertufa retaining wall, you have to adjust the basic formula that is widely used: combine 2 parts Portland cement, 1 1/2 partss peat moss, 2 parts perlite, a little bit of nylon fiber mesh, and 1/2 part coarse sand. The coarse sand will make your hypertufa heavier in comparison with the usual and the fiber mesh will enhance the structural integrity of your creation, making it ideal for a retaining wall.
The subsequent task is to locate the mold for the blocks that will be used for your retaining wall. You’ll want to consider the area where you will be placing your retaining wall so that you will have an idea of the size of the mold that you will need to have. You can use shoe boxes as molds although if you feel that they are not applicable, it’s possible to come up with your own mold using wood, cardboard, or styrene foam used for house insulation. You may also dig block-shaped holes in your yard and cover them with plastic for your mold. Just keep in mind that you’ll want to have plenty of molds as possible. You will require a lot of blocks for a retaining wall and it will take a lot of time for you to cure a hypertufa so it is perhaps a good idea to create all of the required blocks in one batch.
After your hypertufa blocks have been totally cured and are completely ready to be placed, you have to make a mortar mix to keep them together. For that you will have to mix 1 part Portland cement, 2 parts builders sand, Â½ part peat moss or black potting soil, Â½ part clay soil with clods broken up, acrylic fortifying additive, and water. Then line up a layer of your hypertufa blocks, add the mortar mix on the top of the layer, and repeat the procedure until you have put together the retaining wall.
