You may have heard the term “Shoring” from construction workers and may wonder what it means.
Well, there are some bits of technicalities to what shoring means in construction, but we will make things clearer for a better understanding.
In this article, you’ll understand the basics of shoring and what it means in construction.
You’ll also discover some shoring installation techniques, the most commonly used types of shoring, and the general uses of shoring in the construction industry.
The first thing we will look at is the meaning of shoring as it pertains to the construction industry.
Shoring is simply a temporal structure that is put in place during construction projects to prevent the collapse of other structures on the site.
Worthy of mention is that shoring is often deemed unsafe because it mainly serves as lateral support to an unstable structure. So, if the support of the unstable structure becomes weaker and begins to cave in, it wouldn’t be long before the temporal supporting structure (shoring) does likewise.
So, why is shoring installation important in construction phases? Below are some of the reasons and major uses of shoring in construction projects.
You will agree that the exposure of construction workers to mishaps is usually higher during excavation and construction work. This is why shoring is the first preventive measure used in such cases to hold unstable structures in place for a while.
If there are cracked walls in construction sites, it’s necessary to repair them. But first, something has to be done to stabilize the unsettled foundation.
Installing shoring at this point helps to provide lateral support to the unequal settlement of the foundation so that the construction workers can conveniently repair the cracks on the wall.
Knit walls that need enlargement need to be supported; installing shoring is an ideal way to do that. It makes it easier for openings to be made or enlarged on the wall.
Aside from the above, there are many other instances where shoring is necessary for construction projects. For example:
There are different methods involved in using shoring to stabilize structures during construction projects. The type used depends on the project at hand and the severity of the situation.
Here are some of the most used types and what they do to improve construction.

This type of shoring entails positioning a dead shore to be in a vertical form. When the vertical structure is formed, it would then be used to support the horizontal needles.
How to Install Dead Shores
The process is quite simple if you master it.
Below are the steps used to install dead shores to support unstable walls and structures before the continuation of excavation and construction work.
When are Vertical or Dead Shores Installed?
They are used in various situations, including the following.

Secant Pile Shoring is installed when there is a need to interlock walls. The aim is to interlock two walls to form a continuous wall that prevents the collapse of unstable structures.
There are basic elements that must be in place before the interlocking can be done. There has to be an intersection of two combinations of piles. The first pile to be intersected is the Primary or Un-Reinforced Pile while the other is the Secondary or Reinforced Pile.
When is Secant Pile Shoring Required?
There is a bit of risk in the installation of secant pile shoring in construction works. Their proximity and surcharge load need to be considered before installation.
That said, the major applicable case is when there is little or no room for excavation to take place. So, intersecting two walls to form a continuous wall helps to create the much-needed opening for the excavation process to continue.

The next type of shoring on the list is called Soldier Pile Shoring. It is also known as the H or I-Beam Shoring.
In this type, the aim is to support excavation of up to 5 meters deep. It is also used to facilitate excavations of up to 12 meters deep, as well as those that are up to one basement.

Some construction companies consider the installation of diaphragm walls as their last resort to prevent the collapse of unstable structures.
That is because the other options must have been exhausted and deemed unfit before these walls can be considered.
Diaphragm walls use reinforced concrete to promote deep excavations. The use of reinforced concrete is meant to bolster the sustainability of the load that needs to be resisted in the construction site.
It is pertinent to note that the installation of diaphragm walls play an important role in providing temporal and permanent retaining of unstable walls.
Unstable structures pose a great threat to the safety of construction workers and the success of the construction or excavation work.
Installing the right shoring helps to stabilize the unstable structures until the construction process has been completed. This way, the work will go on as planned while the safety of the workers is assured.
