Shoring really doesn’t get much credit in the world of construction although it should do. In regions with hilly terrain and ever increasing density, shoring is not only helpful, it’s often the single most important design ingredient. It allows for construction on what otherwise would be virtually inaccessible, steep or tight building sites.
Given the shortage of empty lots in many urban areas, challenging building sites have become more appealing to home owners and builders. This in turn has created an increasing reliance on shoring. When such building sites are difficult it may be a good idea to arrange for http://www.rmewa.com.au. This powerful type of equipment is ideal for trenching, digging, landscaping and other applications.
Back to shoring
There are a number of types like pin piles, shoring systems that supplement foundations and soldier pile shoring 101. What is shoring? Let’s take soldier pile shoring which is an assembly of vertically oriented steel wide flanges encased in a cylinder of concrete placed every 6 to 8 feet on centre in a straight line. In the construction industry, this is referred to as piles. Wood boards, or lagging as they are known, span horizontally from one wide flange to the next. The entire assembly holds back earth on one side allowing for a vertical cut on the other.
The shoring walls purpose is similar to a retaining wall however the physics and construction methods are very different. For residential projects the height of shoring can range from as little as 6 feet up to 12 feet while commercial shoring project techniques go much deeper. The great thing about shoring walls is that they can be permanent or temporary. Temporary applications are generally supplemented with concrete walls once the earth has been properly retained.
When is shoring used?
Shoring is most effective when the two following criteria are present together on a job site:-
- the necessity for flat ground to build on
- the proximity of the building footprint to a property line or existing structure
The need for flat and buildable ground requires a method of cutting back and retaining the earth. While there are several techniques available to do this, methods like concrete retaining walls need a great deal of space. In order to safely build the framework for concrete footings and walls, the surrounding earth must be temporarily removed, usually at a 45° angle. This must take place on both sides of the wall to provide adequate construction access, hence shoring.
If the structure is too close to a property line under the existing structure, the space required for excavation is very difficult. Talking about excavation, Bobcat and excavator hire Perth provides the right solutions, perfect for building and landscaping projects. All reliable mechanical and earthworks equipment is just what’s needed for larger as well as challenging projects. Likewise, shoring is just what’s needed as the main design ingredient in construction, find out more about the benefits of shoring.
