Steel Waler System

A heavy duty steel waler system where stronger support is required. Each unit comprises 2 No. steel rails complete with two hydraulic cylinders. These are available in a range of different sizes depending on the trench width. The cylinders fit directly on to the rails and are pressurised by a manually operated hydraulic hand pump, giving an uninterrupted column of strength between the trench walls.

A heavy duty system where stronger support is required
Continuous or partial support in trenches
Hydraulic cylinders allow variable trench width adjustment
Ideal for use where services and utilities exist

All units are designed for quick and easy assembly, installation and extraction by one or two people from outside the trench. All units are fitted with mechanical lock-off valves for additional security and to further simplify the installation and extraction process. If the non-battered ends of the excavation require additional support, aluminium Waler End Bearers can be used to provide light weight support.

Hydraulic Waler Frames: Typical Installation Methodology

Waler frames provide 2-way support to trenches and are used in conjunction with trench sheeting. Each unit comprises 2 No. aluminium or steel rails strutted apart by two hydraulic cylinders. The latter are available in a range of different sizes depending on the trench width. This sequence explains the method for installing a Hydraulic Waler System, complete with optional End Bearers within a trench.

Aluminium Waler System

Walers are an accepted and popular method for supporting trench runs. When used in combination with standard trench sheets, aluminium walers offer a light, quick and easy solution for pipe laying activities. The width is also adjustable using hydraulic aluminium cylinders.

Waler End Bearers

The aluminium Waler End Bearer (WEB) system has been developed to be used exclusively with the Groundforce range of aluminium Waler Rails to provide lightweight support to non-battered ends of trenches. Reference should therefore also be made to the Hydraulic Waler Frame User Guide.

Larssen Sheet Piles

Larssen Piles are a type of sheet piling that has an interlocking section which forms a sheet piling retaining wall. Each sheet pile section is connected at 180 degrees from the previous one to form a uniform wall with alternating troughs and peaks. Larssen Sheet Piles are typically used in temporary or permanent cofferdams, retaining walls and foundation construction.

Trench Sheet (Standard)

Groundforce Shorco offer a comprehensive range of cold formed lapped trench sheets and interlocking light pile sections to provide a cost effective solution for most excavation support applications. Many of the sections are produced from high yield steel which provides an exceptional strength-to-weight ratio resulting excellent durability whilst driving and resistance to on-site damage.
