Construction is a very delicate practice where each step and stage if done correctly or not will either fortify or compromise the integrity of the structure being constructed.
In this article we will discuss trenching.
The process of constructing a structure begins with excavating and trenching known as digging the foundation. When digging the foundation, it is very important to note that each excavation has a stand-up time. Stand up time is the time that elapses before the excavation caves in or collapses so before excavation can be done soil samples have to be taken to predict the standup time. Multiple tests may need to be conducted since soil conditions can be dramatically different only a few meters from where the sample of the soil was taken.
There is a possibility of the walls of the trenches collapsing thus in some cases it will be necessary to reinforce the walls to prevent this from occurring.
