Trial Pitting and Slit Trenching

When shallow ground investigation is required trial pit and slit trench analysis provide the best means of determining soil conditions and pinpointing the location of any buried underground services.


Groundbreaking assessments

Professional trial pitting allows subsurface soil types and relative thicknesses to be readily recorded.  The larger size of the exploratory hole gives a clearer understanding of coarse soils, such as gravels and provides a better knowledge of weathering characteristics applicable to rock formations.  Slit trenches allow the professional to easily identify any buried objects, such as underground pipes and cables and to determine their condition, construction and direction - important when planning new service routes through congested streets.
