SPT Split Tube Sampler design for carry out the Standard Penetration Test (SPT) to BS 1377: Part 9: 1990 and ASTM standards. The Top Ball Valve Adaptor, pair of Split Spoons, and open SPT Shoe compose a complete of Split Tube Sampler.

Site Investigation, S.I (or commonly known as Soil Investigation in Malaysia) are crucial in all construction projects.  Site Investigation is usually performed by drilling Boreholes into ground to obtain information on the physical properties of soil and rock around a site for the purpose of earthworks and foundation design of the proposed structures. The soil investigation techniques are also applicable for repair of distress to earthworks and structures caused by subsurface conditions.

Split spoon sampling—also sometimes referred to as standard penetration testing or SPT—is a method of measuring the load-bearing capabilities of the subsurface.
