OUR SERVICES
ENVIRONMENTAL
Environmental drilling occurs in many different types of geologic settings and the project objectives are often very diverse. The drilling methods differ depending on a number of factors, such as the kind of project, the soil at the site, and whether water sampling is involved. Environmental Drilling is a service which is performed to take groundwater or soil samples. These samples are generally required to determine if there is contamination to the area or if monitoring or remediation wells are required to treat the groundwater. There are a number of different drilling and probing techniques which are used as part of environmental drilling.
We offer the following drilling methods:
• Rotary Sonic
• Direct Push
• Solid/Hollow Stem Auger
• HQ Aircore
• ORC Injection
GEOTECHNICAL
Site analysis is crucial for very big structures. Unsafe rock or soil conditions could trigger a structural collapse, or cause a hazardous scenario during an earthquake or flood. The law usually calls for a site to be investigated for safety before a building permit can be granted, and continued safety monitoring must take place to identify any changes or indications of developing problems that could pose a risk to the development. This requires drilling rigs and other drilling equipment to be deployed to the site to be used for the investigation.
Geotechnical drilling methods we offer are:
• Diamond coring – HQ3 & PQ3
• Rotary Sonic
• Rotary Mud
• Hollow Stem Auger
• HQ Aircore
• Automatic SPT
WATER WELL
Envirotech Drilling drill both production and domestic bores all over WA. Domestic bores are typically drilled in a day using a process that involves drilling approximately 10m beyond the water table, the installation of a screen and casing followed by the development of the water supply using an air compressor. The method used allows the drilling of sand, limestone and clay aquifers in the underlaying ground formations.
After the hole has been drilled, a submersible pump is installed and an electrical contractor is employed to wire the pump to the switchboard. The reticulation system is connected to the bore and the reticulation controller is adjusted to suit the pump based system.
EXPLORATION
Investigates for known deposits or suspected subsurface materials such as base metals, coal or other minerals.
Drilling methods we offer are:
• Rotary Air Blast
• Diamond drilling – HQ3 & PQ3
• Rotary Sonic
• Aircore
EARTHING & ANODE
Also known as Earth Testing, Lightning Protection (Earth Rod Drilling), Envirotech Drilling can deliver earth drilling solutions to small and large projects across industrial, commercial and government sectors. No matter the location, we deliver the same high quality service.
We offer a versatile range of services including:
- Earthing installations and testing
- Cathodic Protection
- Geothermal drilling
- Jack hammer driven earth rods
- Deep earth drilling to 150 metres
- Professional grouting service
- Fall of potential testing
- Bentonite grouting
- Geo Loop Grouting unit – This is used for efficiently mixing and pumping earth enhancement materials for tremie hose grouting to eliminate bridging.
Our drilling rigs are available in a variety of sizes, with smaller limited access rigs for confined spaces to all terrain track mounted rigs. The drilling range of our equipment is from 100mm – 300mm diameter by 150 metre depth. All equipment undergoes regular servicing, maintenance and reporting procedures ensure our equipment performs efficiently and complies with strict Australian standards.
Our personnel have been fully trained to use the testing equipment to ensure accurate readings are provided.
Anode Protection
Envirotech Drilling are able to provide drilling for Anode Protection up to 200mm diameter.
UTILITY CLEARANCE LOCATING & NDD
A service locator visits the job-site prior to the start of a project and locates the placement and approximate depth of each type of service pipeline and wires within the scope-of-work areas. With this information, the workers safely and knowingly go about their business having a visual sense of the underground infrastructure. Service Location provides such a service using state-of-the-art non-invasive metallic pipe and cable detection equipment, coupled with, the knowledge and experience to operate the equipment in determining a complete underground pipeline assessment.
Non Destructive Digging (NDD)
Vacuum Extraction is a Non-Destructive Digging (NDD) method, also known as potholing. It is a safe method of excavation and less disruptive than other means of excavation such as shovels, excavators, or post hole borers. It is widely recognised as the safest means of excavation in areas of other underground assets.
Vacuum excavation – or pot holing has become an important part of locating services. Pot holing is a term used for vacuum excavation, when a service is beneath the ground that cannot be seen. Once we locate the service using Ground Penetrating Radar and mark the depth and exact location on the surface, we can then proceed to use a vacuum unit to suck up the soil in a neat hole until we reach the service. Once this has occurred we take a photo of the service and then place an 80mm PVC pipe in the hole and mark on the pipe the depth and what the service is.
When we find many services in a small area or many services that have been laid in the same trench we advise using pot holing to identify each service accurately.
