A versatile shoring solution designed to horizontally brace trenches for the safe installation of utilities in excavations up to 2000mm deep with widths from 650mm to 1450mm. Frames can be installed continuously for an infinite trench length. The system offers clearance between struts on plan of up to 1800mm to allow access. Subject to design, the clearance below the bottom frame can be up to 600mm to allow services to pass beneath.

Designed to withstand a maximum safe working load of 16.5kN/m²,for use in made ground such as soft cohesive and loose granular fill which is generally self-supporting in the short term and where no ground water is present. Use in problematic ground such as very soft clays and silt or peat is not recommended.

The lightweight equipment can be rapidly assembled by hand where access is limited, without the need for an excavator. The hydraulic struts allow the full process to be achieved safely without the requirement for operatives to enter an unsupported trench. ENDSAFE struts are available to close off the ends of a trench providing extra protection from loose materials falling into the excavation.
