Laboratory services
Mos Grondmechanica has a well equipped geotechnical laboratory, in which disturbed and undisturbed samples are classificated and tested. Our geotechical laboratory services include:
- classification tests like volumemasses, water content, Atterberg limits, handtorvane tests
- permability tests
- oedometer tests (loading, unloading)
- different types of triaxial tests
- direct shear tests
- sieve analysis (grain size distribution)
- exposing and photographing of undisturbed soil samples.
- axial compression tests
Tests are performed according to the Dutch and international standards. Besides the geotechnical tests different material tests can be performed, for example on cement-bentonite (including uni-axial pressure test, tension test and the permeability test).

Consultancy
Mos Grondmechanica has many years of experience with consultancy in the geotechnical, environmental and geohydrological fields in relation to foundations for buildings, infrastructure projects and industrial complexes among others. We have for example direct experience with consultancy and advice for:
- shallow foundations on natural soil or on soil improvement, artificial materials, etc.
- pile foundations, bored piles, grout anchors, sheet pile walls, etc.
- sheet pile wall constructions
- settlements, the relation between time and settlement and the stability of roads, railroads, dikes, etc.
- Advices with respect to foundation damage (how the chance on damage can be reduced, or - in case of acted damage - analyze how the damage came into existence and advise with respect to the measures to be taken)
- calculation of jetties
- Advices for horizontal directional drilling (HDD, this concerns among other things the route of the pipeline, the maximum tension force during the pull in operation, the maximum allowable mud pressure in the drill passage and the soil mechanical parameters for the strength calculation) advice for horizontal guided borings (HDD; dit betreft o.a. het leidingtracé, de maximale trekkracht tijdens de intrekoperatie, de maximaal toelaatbare boorspoeldruk in de boorgang en grondmechanische parameters voor de sterkteberekening)
- specific advises for settlements of constructions like overburden tanks and buildings
- geohydrological designs, calculations and advice on behalf of pumpings, infiltration systems, ground source heat exchange, inversed osmose etc.
- environmental advice and sanitations plans
- advice with regard to disputes (e.g. arbitrage cases, lawcourt expert)
Besides the quite usual calculation methods our consultants also use advanced and very powerful calculation programs (including the finite element program PLAXIS).
Based on het expertise Mos Grondmechanica is often invited to participate in national and international study and standardisation commitees.
