An Example Slit Trench used to confirm the location of underground services
Slit Trenches are used as an intrusive confirmatory check on the as-built locations of underground services.
Excavations of Slit Trenches usually combines hand excavation methods and excavation using a small mechanical excavator equipped with a toothless bucket. A site engineer supervises all operations and carries out a detailed survey of the excavation features, such as; the depth, dimensions of the trench, soils strata, the nature, position, dimensions and orientation of any utilities exposed as well as any other relevant information as the excavation proceeds.
Slit Trenches are generally long narrow trenches. They are commonly excavated in urban environments and on roadways to determine the position of existing underground services prior to carrying out planned developments in case they need to be diverted from their current position or avoided entirely.
Our services include provision of a full report where we supply a detailed log of each trench (in plan and cross section) and full as-built plans, drawn-up in accordance with the Client’s requirements.
