If you want a wall in your garden, but don't want to make bricks or use stones, then you might consider building precast concrete walls. These are made up of pieces of precast concrete slab, which you can then use to create a wall. When you are looking for the right type of wall for your garden or driveway, then these can provide an easy and cheap answer to your needs, and they are much more solid and reliable than wire or wooden fencing. Putting up these precast concrete walls is not too difficult, and you should be able to manage to install it yourself without any need of professional help.
Step 1 - Obtain Your Concrete Slabs
Before you can build the wall, you need to have the concrete slabs. Precast concrete walls can be built from a number of different types of concrete slabs, from low, flat slabs which are built up rather like a stone wall, to larger blocks of concrete which are fitted together in the same way as a brick wall. You can also get different types of material in your concrete, from ordinary concrete mixtures to fiberglass concrete, or reinforced concrete with a metal frame. When you are making your choices, you should consider the cost of your items, as well as other needs.
Step 2 - Dig a Hole
The next step is to start digging a hole where you want the wall to go. Use a tape measure to calculate the length of the wall, and then dig out a narrow trench the same size as one of your concrete slabs. Even with a prefab concrete walls installation, you still need to have a foundation. In this case, a hole a few inches deep, covered half-full of gravel and then fitted with the first row of concrete blocks will be enough. Use your backfill to create a small mound around the first layer.
Step 3 - Build the Wall
When you are ready, you can start to build the wall. This involves putting down the first layer, as described above, and then adding a layer of mortar. You should then add the next layer of blocks, and repeat until you get to the top of the wall. Use your trowel to remove any mortar that has slipped between the bricks, and use caulk to cover up any small gaps. You should then leave the wall to dry.
Step 4 - Finishing Touches
When you have finished the wall, you can add more caulk around the holes to ensure that it does not get water damage, or you could consider adding a sealant, which is a sort of varnish, over the top of the wall. This will help to keep out water. Check that the foundations are deep enough to support your wall, and use backfill to build up the outside edge if necessary.
