If approached correctly and taken into account the difficulty level based on retaining, finishes and so on (also see Costs hereunder and Common Pitfalls in next week’s edition) you may be able to save some money by doing it yourself. Concrete is the most common choice because they set fast and they are easy to build. Although they are not as weight-resistant as the other types, this type of partition doesnt cost as much and it is less complicated to build. This wall resembles a cantilever but it doesnt have a second lever arm. This also resembles the cantilever but with the concrete webbings on the rear side as an added feature that connect the lever arm and the wall. What type of extra security measures will be added to the new wall? If, as previously mentioned, a retaining structure is to be incorporated, the fees of an engineer and extra material are to be added to your costs. Wood walls are not so popular nowadays because the material is weak. One advantage of this type of wall is that they dont use much material because of its design.
This is also a good way of breaking the monotony one gets from a too long continuous wall surface. If there are roots in the way, a ground beam or lintels can be spanned from one column to the next. The type of ground on the property can have an impact on the type of construction and materials used. They have a good general knowledge of standard building practices, problem solving and materials. When you plan on building water retaining walls, its probably a good idea you learn a little bit about how water retaining walls work and what you need to do to make sure they dont move, shift and are efficient at doing their job. For instance, if the ground you are building on moves easily or compacts easily, you need to install a footing to keep the retaining walls in place, and avoiding having them sink. You can use perforated drainage pipe that runs alongside the wall, this way the water that normally goes into the dirt will find the pipe and flow away from your water retaining walls. This way the pipe will not become clogged with more wet dirt, and keep the flow of water constant.
This requires complicated construction skills which make them more expensive but highly effective for high loads. When water saturates the soil it places lots of pressure on a retaining wall so you need make allowances for that. Should any existing wall, fence or any other division between properties be taken away or adjusted higher or lower, make sure you consult with your neighbour first. In this, the first of two articles, we will be discussing the initial planning phase, touch on whether you should do it yourself or use a contractor and discuss different costs you can incur with your boundary wall project. In some areas you can build the water retaining walls right on the ground, but in some areas you have to have a concrete footing installed first. Local Municipality regulations. Different areas have different prescriptions. If anywhere else in the world, consult your Local Municipality or Architects in the area. Submitting & approval of your building plans at the local municipality.
See Building Regulations, Plans and Approval in next week’s article for more on adding security measures on top of your wall. I recall a story of an architect that revised the plans of an entire block of apartments to save an old tree. Approach a tree specialist and find out whether the root system is aggressive or not. Step the wall back from the boundary line and build around the tree. Planning your New Wall Determine the actual position of the boundaries where the walls are to be built. This should be approached with care and proper planning. If you are planning to build a free standing or boundary wall, there’s a couple of things to take into consideration. Costs The list of costs of building your boundary wall can include many factors. This means your boundary wall will double as a retaining structure and will have an impact on the design of the wall structure. You shall also have to allow for drainage of storm water damming up behind the wall (See Techniques and Processes next week).
