How to Build a Retaining Wall
When building a retaining wall, you must choose the type of blocks to use. When you are choosing the type of blocks, you should make sure that the ground underneath the blocks is well-compacted. Once you have chosen the type of block, you can now begin installing the blocks. To build a retaining wall, follow these steps:
Building a retaining wall
If you have ever dreamed of building a retaining wall in your garden, this article will walk you through the process step-by-step. First, determine the level of the ground. If the ground is uneven, you could end up with an unstable retaining wall. To avoid instability, you should try building a curved retaining wall. Curved retaining walls bendigo increase the surface area and reduce the load on the wall, while also keeping water and soil at bay.
Next, survey the area where the wall will be built. You should know the existing slope of the land, the types of soil, and how much water it retains during the worst conditions. Be sure not to build the retaining wall on an uneven surface, because each additional row will be uneven. For this reason, use a level gauge at each addition of rows to avoid creating unnecessary voids. The top and bottom courses should be at least one tenth the height of the wall.
Choosing the right type of block
There are many different kinds of retaining walls, so choosing the right type of block is critical for your project. If you are unsure of which type to use, contact a professional landscape designer. They can give you advice on the best type of block for your project based on looks and durability. Here are some guidelines to help you choose the right block:
Concrete retaining wall blocks come in two types: solid and hollow. The latter type features a void and must account for 25% or more of its total area. Concrete blocks with voids are cheaper, easier to handle, and more durable than solid ones. Hollow concrete blocks are more insulating and sound-proof. While you must fill voids before installing them, you’ll increase the stability and structural strength of your entire retaining wall.
Compaction of the earth behind the block
When building a retaining wall, the ground behind the blocks must be compacted. To do this, it is necessary to dig a trench a couple of feet deep and add four inches of gravel or base material. The base of the wall should not touch the slope. The type of soil determines how much earth should be retained behind the block. Sandy soil requires less compacting than clay soil. Depending on the soil type, retaining wall construction will be more difficult. If the soil is filled with a lot of organic matter, such as leaves and twigs, this material should be removed.
Once you have completed all the preparation work, the next step is to lay the landscaping fabric over the blocks. The fabric should be stretched over the gravel and then covered with soil. Remember, drainage is an important function of the wall. Hence, you should consult a professional to get the right design for your retaining wall. Compaction of the earth behind the block is an essential part of the process.
