The Cost of a Borehole
A common question that we are asked is “How much does a borehole cost?” While this might seem like a straightforward question to ask, the answer certainly isn’t. It is the equivalent of asking how much a car costs.
The answer is dependent on various factors. What kind of car do you need? What do you want to use the car for? There isn’t a blanket price for a car, and likewise there isn’t one for a borehole either.
The cost of a borehole is largely dependent on its depth and the amount of casing to be used. The type of rock that we have to rill through also influences the price, as does the actual ground conditions.
While most people expect the easiest drilling to be into soft and loose geologies, the opposite is generally true. A great difficulty of the drilling process is to keep the borehole open during the process, which is made more difficult when the hole is collapsing in on itself because of unstable and loose ground.
We itemise all our quotes, however, in a logical manner that makes them easy to understand, so that the customer is aware of the costs at every stage of the project. A breakdown of the quote is detailed below for your reference.
The Cost of Mobilisation To and From the Site – And the Cost of Drilling
Most rock types are drilled at the same rate. Quartzite, however, because of its abrasiveness, is charged at a higher price, since it wears the drill bit down faster. Some loose ground conditions will also require a different drilling method, such as ODEX – but this is not commonly used in Gauteng.
