A well is the most common way to obtain groundwater for household and agricultural use. Water well drilling provides access to valuable water supplies for domestic, agricultural and commercial properties.

A typical water well can vary from 30m to 80m but can go much deeper depending on water tables.
Firstly, a hole in the ground is drilled using overburden systems and open hole drilling techniques.
It’s important to carry out a pump test once drilling has commenced. During a pump test, water is withdrawn from the well freely until a critical depression head or a safe maximum head is created. Once this is achieved, the rate of pumping is correctly adjusted to maintain a constant water level in the well. This means the depression head remains constant. This is a critical process as the water pumped out needs to equal the water that percolates into the well. This is the yield information of the well.
Once water well drilling has reached its target depth, the borehole is lined with a well screen and plastic casing. Depending on your project, a permanent steel casing may be required.
During the installation of the well screen, a gravel filter pack and bentonite seal are added to protect the well, helping to eliminate potential contaminants.
A sealed chamber is then built over the borehole and the submersible pump is then installed. The pump draws water from the aquifer (the underground layer of water-bearing permeable rock, rock fractures or unconsolidated materials) for distribution through the plumbing system.
This is by far our most common method of drilling. This can be carried out using either air mist or water/mud flush.
This is an increasingly popular technique of drilling for obtaining windowless samples in soil, over burden and made up ground.
This is an effective method of drilling which can be carried out using air mist or water/mud flush and is commonly used for tasks such as detecting coal or even historically mined coal.
Our Putzmeister SP11 mixer is a single axle, road towable, stand alone high pressure grouter.
A typical water well can vary from 30m to 80m but can go much deeper depending on water tables.
An integrated system, offering an innovative solution to undisturbed soil core sampling, groundwater sampling and monitoring.
Site investigation is the initial process we carry out to collect and assess data.
Drilling is required to the suitable depth of the specific site. Typically raging from 100m – 150m.
Our diamond drilling services cut holes quickly and cleanly from 50mm to 300mm diameter and to various depths using barrel extensions. We can core through reinforced concrete, brickwork, stonework, block and asphalt. We use Xcalibre core machines and also hand held which are also ideal for confined spaces, all with a water feed to ensure a clean, dust-free environment.
