As a construction professional, you know that shoring is a critical part of any excavation or trenching project. When done properly, shoring provides the structural support to prevent collapse and ensure the safety of workers. However, not all shoring methods offer the same degree of strength and stability. If you need to shore up an area with heavy loads, unstable soil conditions, or deep excavations, you want to use one of the strongest shoring types available. In this article, you will learn about the strongest shoring type so you can choose the optimal solution for your challenging project requirements. With the right shoring approach, you can achieve maximum support and ensure a successful excavation.
What is Cantilever Shoring System?
Cantilever shoring system is considered the strongest and most versatile above-ground shoring method. It uses heavy steel beams that extend out from a solid wall or structure to provide temporary support.
What is Cantilever Beam?
A cantilever beam is a structural element that extends horizontally and is supported only on one end. The cantilevered beams are embedded into the wall at one end while the other end remains unsupported, creating a “cantilevered” effect. This design distributes the weight of the shored material along the length of the beam, enabling it to handle very heavy loads. Cantilever shoring can be used for shoring walls, bridges, and high-rise structures.
Key attributes of cantilever shoring are:
Made of steel for maximum strength
Steel has a high strength-to-weight ratio, so less material is needed compared to wood or aluminum. Anchored for stability. The embedded end of the cantilever beam is securely anchored to the wall or structure. This anchorage prevents the beam from toppling over under the weight.
The unsupported end of the cantilever beam can be raised or lowered to different heights to match the level of the shored surface. This adjustability allows the system to be used for shoring uneven or angled surfaces.
Cantilever shoring components can be disassembled and re-used on multiple projects, making this a cost-effective shoring solution, especially for contractors.
With its exceptional strength, stability, and versatility, cantilever shoring is the premier choice for shoring in applications where maximum support and load-bearing capacity are required. This type of shoring provides the strongest temporary support for heavy-duty construction and repair projects.
What is Trench Box:
Trench boxes are used to protect workers when performing tasks within an excavation area Providing Powerful Below-Ground Support.
Trench boxes are steel or aluminum structures inserted into an open trench to prevent the walls from collapsing during construction or repair work. They provide maximum support and safety for workers in the trench.
Unmatched strength and durability
Trench boxes are composed of heavy-duty steel plates and beams that interlock to form an incredibly sturdy barrier along the trench walls. They can withstand immense
pressure from surrounding soil and prevent cave-ins even in unstable ground conditions. Trench boxes are reusable and last for many years.
Customize to your needs
Trench boxes come in a range of standard sizes but can also be customized to fit the exact dimensions of your trench. They are modular systems so multiple units can be combined for longer trenches. Access doors and removable panels provide easy access in and out of the trench box.
Easy to install and remove
Despite their robustness, most trench boxes are designed to be quickly and easily installed and removed. They are light enough to be moved into place manually for smaller trenches but cranes or excavators can also be used for larger boxes or difficult site conditions. Once work in the trench is complete, the boxes can be promptly dismantled and relocated to the next job site.
In summary, trench boxes provide unmatched strength and safety for anyone working in or around trenches. Their durability, customizability, and mobility make them an ideal solution for many types of below-ground construction and repair projects. For maximum support, trench boxes are considered one of the strongest shoring methods available.
What is Hydraulic Shoring?
Hydraulic shoring utilizes hydraulic jacks and beams to provide adjustable support strength. This shoring method is ideal for conditions where the soil stability is variable or unknown. The hydraulic jacks can be extended or retracted to increase or decrease the amount of support provided.
Hydraulic shoring systems typically consist of hydraulic jacks, beams, and bracing. The hydraulic jacks provide vertical support and can be adjusted to different heights. Beams span between the jacks to support the wall or structure. Bracing, such as struts, tie the jacks together laterally for stability.
How to Install Hydraulic Shoring?
To install hydraulic shoring, first excavate to the level where support is needed. Position the hydraulic jacks at intervals along the wall or structure, spacing them approximately 6 to 8 feet apart. Extend the hydraulic shoring jacks so they are in firm contact with the wall or structure. Place the beams on Hydraulic shoring offers several benefits. The adjustable jacks can provide the precise amount of support needed for the soil conditions. They also allow for adjustments to be made as excavation progresses to different levels. Hydraulic shoring can support heavy structural loads. It can also be repositioned and reused on different projects, reducing costs over time.
|Are light enough to be installed by one worker
|It tends to be more expensive than other shoring methods, especially for larger excavations
|Are gauge-regulated to ensure even distribution of pressure along the trench line;
|It also requires trained operators to properly install and monitor the hydraulic jacking system
|Can have their trench faces “preloaded” to use the soil’s natural cohesion to prevent movement;
|Close supervision is needed to ensure the jacks remain secure, level, and able to handle the loads
|Can be adapted easily to various trench depths and widths
|Routine maintenance must be performed on the hydraulic equipment.
In summary, for situations where adjustable strength support is critical due to variable soil conditions or heavy structural loads, hydraulic shoring can be an optimal solution despite higher upfront costs. When installed and monitored properly by trained professionals, it provides a safe and versatile shoring method for many excavation projects top of the jacks to provide horizontal support. Install any necessary bracing between jacks for lateral stability.

As you have seen, there are several effective methods for providing strong shoring support during construction and excavation projects. Steel sheet piling, soldier piles and lagging, and secant piles are all tried and true techniques that have been used for decades to stabilize soil and protect workers. By choosing a shoring system based on your specific soil conditions and project requirements, you can have confidence in maintaining a safe work by OSHA standards environment and stable structure. The extra investment in a robust shoring solution will pay off through avoided costs from collapse or failure. For maximum support and peace of mind, steel sheet piling, soldier piles, or secant piles are your best options.
