The do’s and don’ts of building a retaining wall

So, you live in a hilly residential area. You always have to adjust for the environment – extreme temperature, humidity, and altitude. Hillside properties are indeed beautiful. Not only do they draw attention to the home’s architecture but also these dwellings create pleasing views. A home located on a steep hillside presents landscaping challenges. If you wish to counteract soil erosion, protect the soil surface with some kind of cover. Here’s an idea: build a retaining wall. It will put a stop to the negative effects of soil erosion, not to say that it will make your landscape unique. Check out the do’s and don’ts for a successful journey.


Do check with the local authorities

Make sure to check with the local authorities because your little project may require planning permission. The retaining wall’s impact on the natural flow of water could affect your neighbors, which is precisely why some communities have strict criteria regarding permitted development. It’s just like in the case of a Trekkekummer. You may have to submit the plans for your project and schedule an inspection before getting started. Generally speaking, permission is mandatory if the wall is over 1-meter high and in close proximity to a road.

Don’t forget to choose solid materials

The retaining wall needs to be sturdy enough to withstand gravity, as well as the elements. The right materials for a Støttemur are: interlocking retaining wall blocks, landscape fabric, gravel aggregate, industrial adhesive, paver base, mason line, and landscape stakes. Using leftover materials isn’t such a good idea because they’re not up for the challenge. The overage can be deployed in many ways. You can use the leftover materials for the maintenance of the home. Or you could simply make a buck by selling the excess construction materials. Just don’t use them for the retaining wall.

Do begin with a good foundation

You should always build a retaining wall on a good foundation. This way, you have guarantee that the wall will last longer and it will be easier to construct. Since the retaining wall is as strong as the foundation, use crushed rock that prevents the wall from changing position. The exact depth of the trench depends on the height of the wall. If you want to be on the safe side, this is what you need to do: dig a trench that’s 8 of the value plus 3. The foundation won’t be strong enough to handle the pressure coming from the soil if the surface is uneven. Start with an even surface.

Don’t forget to add drainage

Just as it’s important to get Belegningsstein for the retaining wall, it’s important to add drainage to the structure. The role of drainage is to prevent water from building up against the side of the wall. Install perforated pipes and crushed stones underneath the soil. They will allow the water to escape from behind the wall. You could drill holes throughout the retaining wall, but make sure they’re evenly spaced in the vertical direction. Measure the thickness of the wall before getting started.
