Geotechnical Investigations

The necessity of Geotechnical Investigations

To identify the nature of each stratum and engineering properties of the soil, that may affect the design and mode of construction of the proposed structure and foundation.
To identify the water table which may create hindrance during the construction phase.
To locate the groundwater level and possible corrosive effect of soil and water on foundation material.
To ensure the safety of surrounding existing structures.
To achieve a safe and economical design of foundations and temporary works.
To access the general suitability of the site.
