A lightweight, modular shoring solution for excavations up to 2000mm deep with widths from 650mmm to 1450mm. GRP Modular Box panels create a working area 1500mm wide and a minimum under strut clearance of 570mm to allow services to pass. Due to the soil arch created by the hydraulic struts, GRP Modular Boxes can be set out with a clear space of up to 1500mmm between boxes making anefficient solution for longer trench runs.

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 or in excavations where a high volume of services are expected to cross the trench 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.
