Reliable Soil Testing &
Geotechnical Investigation Services

Geotechnical investigation is the process of physically drilling, sampling, and analyzing subsurface soil and rock layers at a construction site. It determines critical ground properties—such as soil bearing capacity, settlement behavior, groundwater level, and strata stratigraphy. Building codes mandate it before foundation design to ensure structural safety and prevent foundation settlement or failure.

Soil testing reveals the hidden physical and chemical characteristics of the ground beneath your project. Without it, foundations may either be dangerously under-designed (leading to structural cracks, tilt, or foundation failure) or needlessly over-designed (wasting millions in excessive concrete and steel reinforcement). Accurate soil testing provides the precise parameters required for an economical and safe foundation design.

The Soil Bearing Capacity Test determines the maximum safe structural load that foundation soil can sustain without undergoing shear failure or exceeding permissible settlement limits. It is typically conducted through in-situ Plate Load Testing (PLT as per IS 1888) or derived through borehole drilling and laboratory shear testing.

The Standard Penetration Test (SPT) is an in-situ dynamic test conducted inside a borehole as per IS 2131. A standard split-spoon sampler is driven into the soil using a 63.5 kg hammer falling freely from 750 mm. The number of hammer blows required to achieve 300 mm penetration gives the "N-value", which directly correlates to soil density, friction angle, and bearing capacity.

Field exploration (borehole drilling, SPT, and sample retrieval) typically takes 1 to 3 days depending on borehole depth and total quantity of points. Subsequent laboratory testing (moisture, density, grain size, chemical analysis) and final technical report compilation usually require 3 to 7 working days, depending on project scope.
