A retaining wall has the main purpose of keeping soil behind the structure. Just consider the potential impact of a landslide because of structural failure during heavy rains, and it becomes clear why it is imperative to properly construct a retaining wall using superior quality materials as available from us. The location and purpose of the structure are important. Before choosing the materials, it is imperative to determine the exact purpose of the wall, such as:
- Is it for landscape purposes to create additional planting space or to create an idyllic pause area in a corporate environment?
- Is it built specifically for retaining soil from the higher lying area behind the wall?
- Is it to be constructed to keep soil from spilling onto a road?
- Is the structure for corrosion control or to create a terraced landscape?
Below are some considerations to keep in mind regarding the location of the retaining wall.
1. What is Beneath?
Determine the location of underground utilities, such as communication and power lines, irrigation pipes, and stormwater drainage systems. The extra weight on the soil below can cause a drainage pipe to collapse. Also, you need to be careful not to excavate into power lines.
2. Where to Go with The Extra Fill Materials?
Where will the soil be stored for filling the hollow spaces in the retaining wall blocks? Keep in mind that you need space for keeping the materials to fill up the hollow spaces. It may not be an issue if the surrounding area is level. However, if you already work on a steep slope, it can be difficult to store the filing on site until you are ready to fill the blocks.
Excess soil from cutting into a slope or hill must be stored somewhere or removed. Do you have the necessary space? If not, you will need to plan for the immediate removal from site.
3. How Does it Affect Drainage?
Although the structure is ultimately meant to prevent corrosion and to keep soil back, it can affect the natural drainage of the area. You thus need to determine what the current state of drainage is and how the structure will affect it. You can include Waterway 400 retaining wall blocks to prevent water running over the face of the wall.
Careful planning should go into the creation of sufficient drainage where needed.
4. Where is The Property Line?
If you plan on building the wall on the boundary of the property, you first need to determine the location of the property boundary lines and how building regulations affect the construction of the structure according to its height. Far too many property owners end up having to demolish boundary structures because their boundary structures encroach on the neighbouring properties. As a contractor, you must make sure where the property lines are located.
5. What is The Load From Above?
What is the surcharge weight? Determine the type and exact weight of the structures above the wall. Keep in mind that the force of these will put strain on the structure. As such, it must be strong enough to carry the weight of and withstand the force from above. Such loads can range from a swimming pool on the terrace above the retaining wall to guardrails and parking areas where vehicles move.
We briefly touched on factors to consider regarding the location of the retaining wall. However, many other factors play a role in the proper construction of the structure. Even with all factors considered, if the materials you choose to use are sub-standard, you can expect the structure to fail. To prevent this from happening, buy concrete retaining wall blocks from a trusted supplier of materials. We offer you superb quality and help in choosing the right materials from our product stable.
