EXCAVASION
GTM provides a detailed excavation services tailored to the specific needs of each customer (commercial or residential). The estimate is free and we do not fear challenges such as steep terrain, running in reduced space, the French drain installation in unstable ground, the toughest strains, etc.

DECONTAMINATION
The goal of any environmental study is to determine whether items such as soil or water, or even air, present on land are contaminated or not.
This study takes place over several stages or phases:
  1. The first step, also known as Phase I is characterized by the development review of information available on the site and is to the history of the site and activities that could accommodate. This is a preliminary stage whose main objective is to become familiar with the terrain and define the problem from the available data.
    When enough data gathered in Phase I, we move to Phase II is the study itself.
  2. During this phase, it is to explore the data collected during Phase I for the presence of contaminants, to determine the source, but also to determine contaminated elements and extent of the contamination. This phase is characterized by the sample survey (soil core) to be studied indirectly. This phase can be pushed a little further, when one is looking for other items which explain the contamination. This is called comprehensive phase II.
  3. The results of Phase II open the way to Phase III. The latter is more comprehensive than Phase II as it seeks to draw the boundaries of the contamination more accurately, to determine the volumes of contaminated materials, identify the effects of contamination on the environment but also to assess the risks to human health, wildlife and flora. This step aims to be more detailed than the first preliminary step called (stage I and II), and to define the appropriate response measures. Several samples are necessary for the success of this phase. The environmental study can sometimes be insufficient, as it is necessary to make additional or special studies. For example, when to choose a treatment technique or in the evaluation of toxicological or ecotoxicological risk. The environmental study makes it possible to determine the intervention scenario, based on data collected during the study, all to minimize the impact on the environment but also on human health, the fauna and flora
