Basement Lowering Process

What is included in Basement lowering process?

Basement lowering is a renovation procedure that has proven to be very beneficial in so many aspects. This renovation procedure has eliminated the need of acquiring new land for expansion. It gives a house owner an alternative of going down if he or she has o space to expand outwards. Many old structures have been made stable and strong through basement lowering. Upon hearing it, you might think that basement lowering is a onetime activity, but, that isn’t the case. Basement lowering is a detailed construction strategy that needs to follow a well-stipulated procedure. Just like any other construction procedure, basement lowering has its specific way of doing. There are laws and guidelines that guide architects and engineers as they conduct the entire process. There are many things that need to be focused on before undertaking a basement lowering procedure. Some of the things to be included in basement lowering process include the following.

  1. Preliminary study of the structure undergoing basement lowering

The first and most important thing to be included in a basement lowering process is the preliminary study of the house. A preliminary study basically helps the engineer come up with ideas of how the entire process will be undertaken. During the preliminary study, the type of material needed to build the basement is identified. A preliminary study also sees it that the engineer comes up with a clear design of how the basement should look like. During this stage, possible risks are also identified and risk management procedures put in place.

  1. Identification of the basement lowering technique

Before basement lowering process is carried out. A technique to be used in the entire process has to be identified. There are two basic techniques that can be used in this process. These techniques include underpinning and bench footing.

  • Underpinning

This is a complex basement lowering technique that needs the hands of professionals for it to be successful. Underpinning is a very risky technique, if not well handled, it may cause a lot of destruction, injury and even death. Basically, underpinning involves excavating some portions of the ground under the basement of your house or structure. After the earth is excavated, the engineers on ground pour concrete blocks to replace the excavated soil. The blocks will be allowed to dry for a period of a few days. After the concrete dries, the same procedure will be done on adjacent sections until the entire basement is complete.

  • Bench footing

Bench footing is a very simple basement lowering technique. It doesn’t include risky and complicated procedures. But this does not mean that you can do it on your own. It is always advisable that you seek the help of professionals when it comes to basement lowering. It doesn’t matter how simple the process might be. Bench-footing involves excavation around the foundation of the structure and not under it. After the excavation process is complete, new foundation walls are built. This will create a bench-like structure between the old foundation wall and the new floor.

  1. Excavating the soil under or around the original foundation

After identifying the technique to be used. The basement lowering process will begin by excavating the soil. Excavation will be done in accordance with the technique you choose. As observed earlier, the underpinning technique will call for excavation under the original foundation, while bench-footing will call for excavation around the original structure.

  1. Pouring of concrete blocks

After excavation, concrete blocks are then poured to fill the void space left after excavation. The concrete is always allowed to dry up before a next step is taken. This is to allow it to become very strong and firm.

  1. Inspection

Before the basement lowering process is complete, inspection has to be done so as to ascertain whether the process has been undertaken in accordance with the stipulated laws and procedures or not. Inspection is usually done by a city inspector. The city inspector will give a go-ahead in the type of materials used and the technique used in the entire basement lowering process.

  1. Materials and equipment

Some of the crucial things that ought not to be forgotten are the tools, equipment, and materials used to carry out the entire process. Tools like spades and daggers are used in the excavating process. Different types of machinery can also be involved. Materials to be involved in the process include cement, metals and concrete blocks.

Finally, for a basement lowering process to be counted as successful, all the above named should be included in the process. One has to be very careful when selecting a basement lowering technique since not all techniques will work on all types of soil. If you are not sure of the technique to employ, you can seek advice from specialists.
