Peat is basically a problematic soil as it is high in compressibility and low in shear strength. Therefore a suitable sampler known as TROPITER was invented to solve all the common sampling problems in tropical peat. The TROPITER is an apparatus for sampling intact,undisturbed peat samples in the peat lands. This sampler has a number of features which are considered to be in advantage both for field work and for the subsequent laboratory investigations of peat deposits. These advantages are listed in the next slide. TROPITER is a brand new soil sampler that has multipurpose functions. This sampler has been tested and has worked satisfactorily in many different types of soil apart from peat. Hence the invention of TROPITER in the construction technology will contribute to the ground improvement of tropical peat and provide better solution to this problematic soil.
