ENVIRONMENTAL DRILLING

Meticulous soil sampling methods are employed by Epoca Environmental Pty Ltd to ensure the highest quality samples maintain integrity between origin and our Clients’ sample containers. Combined with an understanding of the importance of precise groundwater monitoring well and soil vapour probe installations, Epoca ensures an overall service of integrity and reliability for consultants’ assessment of chemical and physical subsurface soil, groundwater and soil vapour conditions.

The below technical specifications outline each of our rigs' capabilities for environmental investigation projects.
All of our plant and equipment is purchased  new and is fully maintained for optimum performance and reliability on site.
