Borehole Screens & Casings
Our PVC/HDPE borehole casings and screens are specially designed to cover all aspects of water supply and movement. We offer a comprehensive range of PVC pressure pipe and fittings to meet all your water supply needs.
In addition, we have a vast selection of HDPE casings, screens, pipes, and fittings. Our products also include lifting bails and swivels for easy installation.
PVC Borehole Casings & Screens
PVC-U casings and screens have excellent mechanical properties and are manufactured with selected PVC compounds to provide non-corrosive pipes.
Two ranges available: 0-100m standard and 100-200m heavy duty.
- Insensitive to corrosive materials and liquids
- High mechanical strength under tensile loads and excellent resistance to high collapse pressures
- Slots are accurately and consistently cut to provide flow rates consistent with calculated values to be used when designing systems
- Cheaper than conventional steel casings
- Threaded casing joints are robust and reliable over long periods of time and flush joined for improved flow of pumped water
- Simple assembly
- Lightweight
Applications:
Waterwells
Mine dewatering
Sea water abstraction
Geotechnical drilling
Water monitoring

PVC Pipes & Fittings
PVC is one of the most versatile pipe materials on the market. It is produced by the polymerisation of vinyl chloride which is made from coal (or oil) and common salt. In fact, salt makes up over 50% of the polymer, making PVC one of the most environmentally friendly plastic materials as it is least dependent on hydrocarbon resources.
The unique properties of PVC can be enhanced by the addition of special additives, for example, to create strong yet tough pipe materials (such as modified PVC, PVC-M), foamed or multilayer sewer and drainage pipes, and weather resistant, above ground drainage pipes.
We supply a full range of PVC pressure pipe and it’s fittings as well as unplasticized dark grey PVC pipe.
- Reduces frictional losses through excellent flow characteristics
- Best long-term strength/cost ratio of all pipe materials. Lowers the capital cost of projects for the provision of potable water and sanitation
- A unique combination of mechanical properties including long-term strength, toughness and stiffness making it ideal for pressure and sewer and drainage pipes.
- Larger bore and high flow capacity which lowers pumping costs and overall energy requirements.
- Durable and tough. resistant to handling, transport and installation damage.
- Resistant to acids and alkalis. Able to work in acidic soils and resistant to the acidic chemicals in sewage and in mining.
- Resistant to abrasion and scouring and modern cleaning methods. Ideal for use as sewer and drainage pipes.
- Lightweight for lower transport costs and easy handling and installation, ideally suited for labour intensive projects. About 20% the mass of an equivalent steel pipe.
- Elastomeric locked-in sealing ring system that is resistant to most chemicals, long-term sealing performance and easy, low cost installation with unskilled labour.
- Inflammable and suitable for use in underground mining with specially filled hydraulic joints.
Applications:
- PVC Pressure pipes are specified with confidence in the following applications:
- Water mains and reticulation systems
- Irrigation
- Mining
- Industrial applications
- Sewer effluent control and water purification
- Enhanced hydraulic characteristics
- Drinking water for public, private or industrial networks
- Sewage systems
- Sewage water mains
- Piping for conveyance of liquid foodstuffs and industrial liquids
- Underground irrigation systems
HDPE Casings, Screens, Pipes & Fittings
HDPE Casing & Screens are a popular choice for water wells, soil monitoring, bio-gas abstraction from landfill sites, mining and other industries. HDPE has a number of benefits over traditional materials. It is lightweight, non-corrosive, non toxic, fatigue resistance and facilitates ease & speed of installation.
HDPE Casing & Screens are particularly preferred for soil monitoring and landfills as it has excellent resistance to a variety of aggressive chemicals.
HDPE pipes are a lightweight and highly efficient material for waste and rainwater drainage. With a high resistance to chemicals they are also suitable for clinical and industrial waste.
HDPE pipes can be used in applications from -40°C to +95°C and are suitable for installation below ground.
