Both scaffolding and shoring are commonly used in the engineering and construction industries. Though both systems are common, they’re not at all the same. Choosing the right system is a must for ensuring safe use, so before purchasing or renting scaffolding or shoring, contractors should read on to find out about the critical differences between these two products.
What Is Shoring?
Shoring is a product designed to provide vertical support in formwork systems. These temporary systems can support structures during construction, renovations, repairs, or even demolitions. There are five primary types of shoring:
1. Diaphragm Walls
Diaphragm walls are a type of reinforced Concrete Deck Shoring System commonly used in deep excavations. Contractors use them to create basements, tunnels, and other underground structures.
2. Sheet Pile Shoring
Sheet pile shoring includes steel piles, which can be driven into the ground using a vibro hammer. They’re used to support piles and are very common in excavations around bodies of water.
3. Contiguous Pile Shoring
Contiguous pile shoring is similar to sheet pile shoring. However, it’s used primarily in clay soils and areas where water seepage does not regularly occur.
4. Secant Pile Shoring
Contractors can use secant pile shoring when there is no room for open excavation. It consists of interlocking primary and secondary piles that can be installed in small spaces.
5. H- or I-Beam Shoring
H- and I-beam shoring is used to support standard excavations ranging from 4 to 15 feet in depth. The beams are drilled into the ground.
What Is Scaffolding?
Scaffolding is a type of temporary system used to elevate or suspend workers and materials above the ground. It’s usually built alongside structures to perform construction, renovation, repair, and demolition work and is removed when the job is done. Common types of scaffolding include:
1. Single Scaffolding
Single scaffolding is composed of standards, ledgers, and putlogs. It’s commonly used to complete brick masonry work.
2. Double Scaffolding
Double scaffolding is commonly used in stone masonry. It features a second row of scaffolding support that accommodates the difficulty of creating holes in stone walls for putlogs.
3. Cantilever Scaffolding
Cantilever scaffolding can be either single-frame or double-frame. Either way, it features standards that are supported by needles that run into the walls. Its primary uses are accessing the upper levels of high walls or working in areas where the ground doesn’t provide enough support.
4. Suspended Scaffolding
Suspended scaffolding features ropes or chains that can be affixed to a structure’s roof, allowing the scaffolding to be raised or lowered as needed. It’s commonly used for repair work, painting, and window washing.
5. Trestle Scaffolding
Trestle scaffolding features platforms supported by movable tripods or ladders. It’s usually used indoors.
Primary Purpose of Scaffolding vs. Shoring
The most important difference between scaffolding and shoring is their respective purposes. Scaffolding is designed to provide a deck for workers to stand on while performing tasks. Shoring creates a deck that acts as part of the formwork that shapes or supports a structure while it is being constructed.
Find the Right Products
Not sure whether a construction, repair, or demolition project will require scaffolding, shoring, or both of these systems? The best thing to do is to reach out to a reputable vendor and ask questions. Describe the intended use, then purchase the system that will be best suited to accomplish the job safely.
