Log the hole
As we drill, we record the layers we pass through so the casing design matches the real ground.
Water Systems
Casing that keeps your borehole stable.
Casing holds a borehole open and keeps unwanted material out of your water. Poor casing leads to collapse, sand in the water and a shorter borehole life. We select and install casing and screens to suit what we find in your ground.
What we do
- Casing and screen selection based on the layers met during drilling
- uPVC or steel casing, depending on depth, ground and use
- Screens placed against the water-bearing zones
- Gravel packing around the screens to improve flow and keep sand out
- Sealing at the surface to keep contaminated runoff out
- Inspection and advice on the casing of existing boreholes
Signs of a casing problem
- Sand or mud keeps coming through your taps
- The borehole has partly collapsed or the pump keeps getting stuck
- Water turns dirty after heavy rain
- Yield has dropped sharply for no obvious reason
- You are comparing drilling quotes and want to know what casing is included
How it works
One accountable team from the first call to the day the water flows, and after.
Design
We decide the casing type, where the screens go and the gravel pack, based on that record.
Install
We lower the casing and screens to the planned depth and alignment, then place the gravel pack.
Seal and develop
We seal the top against surface water and develop the borehole until the water runs clear.
Why casing matters
Casing is the part of the borehole you never see again once it is finished, and it is very hard to fix later. Many sand, collapse and contamination problems trace back to casing, screens or sealing. Getting it right during drilling is the cheapest protection for your investment, which is why we explain our choices and list casing clearly in our quotations.

Frequently asked questions
Why does casing matter?
It holds the borehole open and keeps unwanted material out of your water. Poor casing can cause collapse, sand and a shorter borehole life.
Should my borehole use uPVC or steel casing?
uPVC suits many domestic and farm boreholes. Steel may be chosen for deeper or high-demand boreholes, or for particular ground conditions. We recommend what suits your site and explain why.
Why is there sand in my water?
Sand can come from a problem with the screens, the gravel pack or the borehole's development, or from a failing pump. We need to inspect the borehole to say which.
Is casing included in the drilling quote?
Ask us to list the casing and screens separately in your quotation so you can see exactly what is included. We do this as standard.
Can casing be repaired after the borehole is finished?
Some problems can be managed through rehabilitation, but casing is hard to fix once it is installed. Getting it right during drilling is the best protection.
