Environmental Investigation:

Assessments, Audits, and Monitoring of water quality of soil both terrestrial and marine environments are undertaken. GIS carries out these investigations through sampling of groundwater and soil for biological, chemical and physical properties, carrying out analysis and making recommendation to remediate and monitor.  GIS posses sampling equipment that can sample to depths of 20m in required.  Samples can be taken from land or water (sea or lake).  GIS has a team of professional with varying background to assess a wide verity of environmental problems. 


Geotechnical Investigation:

GIS offers a wide range of services with it gauged to inform the design and structural engineers about the subsurface conditions with regards to foundation design for structures, sewage disposal, and road construction.  Bearing capacity testing such as Standard Penetration Tests, soil permeability and percolation testing can be carried out insitu.  GIS’s drill rigs can drill and sample to more than 20m if necessary on land and water.


Geophysical Survey:

This is a non-destructive method of investigating the subsurface.  This method is very common with regards locating deposits such as quarries.  This investigation gives the best results with some degree of drilling to reference the resistivity readings.  Resistivity survey is quicker and can cover a larger area with limited resources.


Mix Designs:

Concrete – The various strengths of concrete under various delivery conditions could be tricky.  GIS takes the guesswork out of concrete design with years of experience and data as regards to the aggregate and cement strength. 
Asphalt- Years of working with asphalt on major road projects in Grenada has position GIS with the experience in designing different types of asphalt mixes best suit for a variety of conditions.


Construction Testing:

Consultation for the best use of various natural aggregates locally and imported as well as quality control at the job site, GIS provides compaction testing, sub-grade testing, concrete and asphalt testing and analysis.
