The Problem
If your looking for Hydrocarbons or chemicals in the
ground then PVC is not the best material to be used as
the above chemicals will attack the PVC and very quickly
it will be dissolved and disappear, making the bore
useless.
Below is information on the alternative material you can
use for your environmental or borecasing and screen
project.

Steel
Advantages:
• Steel can be set deeper than PVC
• Cost of using Steel is better in the long term
Disadvantages:
• Steel has a poor resistance to chemicals in the
ground and water. If the bore is to be in the ground for a long period then steel is not recommended.

Advantages:
• It is excellent in most chemical environments
• Is it non Tainting
• And has considerable life expectancy
Are you considering putting down Deep Bore in Harsh
ground environment?
316 Stainless Steel is a great alternative
Stainless

Ph 1300 133 000
Disadvantages:
• It is expensive compared to the other plasticize
material.
Due to its strength it has a very high depth
setting capability.

Advantages:
• You can take a sledge hammer to this
material and all you will do is tire your arm out.
• It has sensational resistance to chemicals.
• Ample Sizes available
Many process plants use this throughout their
manufacturing plant.

Ph 1300 133 000
Disadvantages:
• It is approximately double the cost of PVC
• Low Resistance to UV Rays
• Moderate Heat, moisture and chemical Resistance
ABS (Acrylonitrile Butadiene Styrene)

Ph 1300 133 000
Advantages:
• A very strong material
• Great resistance to harsh chemicals,
• High tensile strength deep installations can
be achieved.
With the above positives and a complete resistance to
electrolyzes many government water boards highly
recommend using Fibreglass as the bore casing.
Fibreglass

Ph 1300 133 000
Disadvantages:
•Can be very expensive in the larger sizes
• Jointing on site can be a little difficult in both hot
and cold weather
Often stainless steel screens are used as slotting of
Fibreglass is very difficult.

• Rugged material and
• Strength and rigidity
• Fantastic Resistance to chemicals and corrosion.
• Very high impact and temperature resilience.
The downside is the range and supply of this pipe is limited.
Polypropylene

Ph 1300 133 000
Advantages:
• Perfect for Shallow Installs.
• Suits applications when you are looking for
hydrocarbons
Deps has supplied 50mm poly casing and screens on many
occasions and the majority being overseas, the material has
excellent resistance to hydro carbons, is light weight and
can be made in any lengths.
HDPE (High Density Polyethylene)
Bore Casing & Screens Pipes & Components Environmental Drilling Water Treatment Safety Products Sand Spears Pumps
Ph 1300 133 000
Disadvantages:
• Very low tensile strength (making it useless in deep
environmental bores.
• Water well drillers do not like this material due to its molecular
weight being lighter than water makes the material float when
in water.
In a particular job the driller came back the next day to see his
recent installed borecasing above the ground for 20m plus in the
air. This was caused by coating characteristics.

Remember as the Famous author Poet John Ruskin stated
“The bitterness of poor quality lingers after the sweetness of low price is forgotten”
