Hard-Rock Water Bore Drilling Services

Accessing groundwater in the Perth Hills requires equipment and experience suited to hard-rock conditions. Unlike the sandy soils found across parts of the coastal plain, many properties throughout the hills are located over granite and other fractured-rock formations.

B&T Drilling specialises in drilling through these challenging ground conditions. Our truck mounted rigs are designed for hard-rock water bore drilling while remaining suitable for access on rural properties and larger residential blocks.

Every property is different, and groundwater cannot be guaranteed before drilling. We use available groundwater records, surrounding bore information, geological conditions and our own drilling experience to help identify a suitable location and plan the work.

Our objective is to construct the bore properly, document the conditions encountered and provide the information required for appropriate pump selection and ongoing bore management.

Our Approach To

Hard-Rock Water Bore Drilling

A successful drilling project requires practical experience, reliable machinery and careful planning.

Before mobilising, we discuss the property, access conditions, intended water use and any available information about nearby bores. We also consider the position of buildings, fences, powerlines, underground services, septic systems and other site features that may affect the proposed drilling location.

Because hard-rock drilling can represent a significant investment, we provide clear information about the process, likely drilling conditions, pricing structure and the uncertainties involved before work begins.

Once on site, our crew works carefully to establish a safe operating area and minimise unnecessary disturbance to the surrounding property. Throughout drilling, we monitor the formations encountered, groundwater inflows and bore performance to help determine the most appropriate course of action.

How We Work

01

Site Assessment and Bore Siting

Before the drilling rig is mobilised, we assess the proposed location and review available groundwater and geological information.

This may include nearby bore records, regional groundwater data, our own drilling history and an inspection of the property. Where requested, an experienced water diviner may also be involved in the site-selection process.

No assessment or bore-siting method can guarantee that groundwater will be found or predict its final yield or quality. The purpose of this process is to identify a practical drilling location based on the information available.

02

Mobilisation and Setup

Our truck-mounted drilling rig and support equipment are mobilised to the property and positioned on a suitable, accessible area.

Before setup, we consider overhead and underground services, buildings, gates, fences, vegetation, drainage and the space required to operate safely. We take reasonable care to minimise unnecessary disturbance, although access by heavy vehicles may leave some impact on soft or wet ground.

03

Hard-Rock Drilling

We use pneumatic down-the-hole hammer drilling equipment to advance through granite and other hard-rock formations.

During drilling, our crew monitors changes in geology, groundwater inflows, drilling depth and airlift performance. These observations help guide decisions as the bore progresses.

The final drilling depth depends on the ground conditions and water encountered. Any decision to continue or stop drilling is discussed with the client where practical, particularly when drilling moves beyond an estimated or nominated depth.

04

Casing and Bore Development

The bore is constructed using casing selected to suit the conditions encountered and the intended bore design. Depending on the geology, this may include PVC or steel casing and appropriately positioned screened or slotted sections.

Once drilling and construction are complete, the bore is developed using compressed air to remove loose material and sediment from the hole. Development continues until the bore has been adequately cleaned based on the conditions encountered.

We then record the bore depth, geological formations, groundwater inflows and measured airlift flow. This information is provided to assist with pump selection, although the long-term performance and water quality of a bore may vary over time.

Essential Questions Answered

How do you assess whether there may be groundwater on my property?

Groundwater cannot be confirmed before drilling begins. However, we can review available information to help identify a suitable drilling location.

This may include nearby bore records, geological and groundwater data, our own drilling history and the position of the property within the surrounding landscape. Where requested, an experienced water diviner may also be involved in the site-selection process.

These methods can help guide the decision, but they cannot guarantee that groundwater will be found or predict the final flow rate or water quality.

Will the drilling equipment damage my property?

Our truck mounted drilling rigs are suitable for rural properties, farms and larger residential blocks of one acre or more. Before mobilising, we assess gates, access tracks, overhead clearances, fences, vegetation and the space available for the rig and support vehicles.

We take reasonable care to minimise unnecessary disturbance to the property. However, drilling equipment is heavy, and some marking or ground disturbance may occur, particularly where the soil is soft, wet or uneven.

We will discuss any access concerns with you before the equipment enters the property.

How deep will you need to drill to find water?

There is no standard drilling depth for groundwater in hard-rock areas. Conditions can vary considerably between neighbouring properties depending on the geology, elevation and the location of fractures within the rock.

Some bores may encounter water at relatively shallow depths, while others may need to be drilled beyond 100 metres. Before work begins, we review the available local information and explain the likely drilling conditions and pricing structure.

The final depth will depend on what is encountered during drilling.

What happens if no groundwater is found?

Although we carefully assess the proposed location before drilling, there is always a possibility that a bore may be dry or produce an insufficient flow.

We explain this risk before work begins and provide clear pricing so you understand how drilling costs will be calculated. During drilling, we monitor the formations and groundwater inflows and keep you informed of the results.

Where practical, we will discuss whether to continue drilling, stop at the current depth or consider another location. Drilling costs remain payable for the work completed, regardless of the final groundwater result.
