Borehole Casings in Zimbabwe

Casing is a large-diameter pipe that is assembled and inserted into a recently drilled section of a borehole. 

Similar to the bones of a spine protecting the spinal cord, casing is set inside the drilled borehole to protect and support the water stream.

We instal uPVC the 140mm and/or 180mm borehole casings and they come in two pressure classes, Class 6 and Class 10.

Borehole casings are manufactured with selected PVC compounds to provide absolute non-corrosive pipes with excellent mechanical properties.

The casings are joined by the use of solvent cement.

Advantages Include:

1. Corrosion: The chemical inertness of uPVC makes them insensitive to all forms of corrosion, thus being excellent products for use in Borehole Drilling.

2. Cost-effective: Lower installed cost compared to conventional (steel) casings.

3. Easy handling and installation: Tough, rugged material, with easy to assemble joints.

4. Lightweight: Much lighter than steel casings, makes them user-friendly installations and saves time.

5. PVC plastic material: Resistant to corrosion as well as acids and alkalis found in some soils. No additional protection required.

6. Internally and externally flush jointed: Easy installation in a borehole and improved flow of pumped water.

7. High modulus of elasticity: Makes for stiffer casings and screens which can be designed for boreholes up to at least 200m deep.

Five Facts About Borehole Drilling That You Need To Take Note Of:
1. Know Your Borehole Casings:The Preferred Borehole Casing In Zimbabwe Is Class 9 and 10 (Pressure Classes.)This is because Class 9 and Class 10 Casings are more collapse resistant. The strength of a Casing is often described as collapse resistance.

2. Borehole Drilling Depth: The exact depth, of where the water is located, cannot be established by the drilling contractor nor the Water Surveyor (Borehole Siter).

3. The Is No 100% Guarantee On Water: It is important to note that it is never a 100% guarantee that any hole will yield water, the amount and water quality can also not be guaranteed by the drilling contractor and water surveyor.

4. Borehole Siting or Water Surveying Is Important: Making use of a hydrologist or traditional water diviner will increase your chances of having a successful borehole that will yield a sufficient amount of water.

5. Know The Risks: The risk of the borehole drilling lies with the property owner. The client will still be liable for the drilling costs irrespective of a borehole yielding water or not.
