Our Standard Lap Trench Sheets offer a robust solution for supporting the vertical faces of small to medium-sized trenches and excavations between 1m and 9m in depth. These sheets ensure stability and safety during temporary excavation and construction work. Manufactured to conform with BS EN 10249-1:1996 and BS EN 10249-2:1996 standards, each sheet features a standard effective width of 330mm and is available in various lengths to suit specific project needs.
Our trench sheets, efficiently handled and installed using an excavator's bucket to drive them vertically into the ground, are designed with user convenience in mind. They come with handling holes as standard, making them easy to manipulate and position. These sheets are compatible with our range of shoring products, offering lapped and interlocking systems to accommodate different site conditions, ensuring optimal alignment and performance for each project's unique environmental and structural challenges.
