Borehole Casing Standards in Zimbabwe: Why Class 10 is the Only Choice
Physics of Ground Pressure, Material Science & Long-Term Asset Value
Investing in a borehole is a significant financial commitment. In Zimbabwe’s diverse geological landscape—from the hard rock of the Mashonaland plateau to the shifting sands of Matabeleland—the "unseen" components determine your well's lifespan. At Nakiso Borehole Drilling, we advocate for the structural integrity of Class 10 PVC casings over inferior alternatives.

| Engineering Integrity: Every meter of a Nakiso borehole is shielded by Class 10 casing. |
1. The Physics of Ground Pressure
A borehole is essentially a vertical "straw" into the earth. Once the drilling rig leaves, that straw is the only defense preventing the weight of the surrounding earth from reclaiming the space.
Superior Collapse Resistance
Class 10 casings feature a 10mm wall thickness. In engineering terms, this provides the critical "SDR" rating needed to withstand lateral ground pressure without "ovalizing" or buckling.
Managing Soil Movement
Zimbabwean earth is not static. Moisture changes and tremors cause ground shifts. Thinner Class 6 pipes are prone to snapping under this stress, which can trap your submersible pump and destroy your well.
2. Virgin PVC vs. Recycled Materials
The "Class" of a pipe determines its thickness, but the resin quality determines its lifespan. Nakiso insists on 100% Virgin Material.
Manufactured from "first-use" plastic. It possesses maximum molecular bonding, offering high tensile strength and impact resistance. It flexes without snapping.
Often made from "regrind" plastics containing impurities. Over 5-10 years, these lead to Environmental Stress Cracking (ESC), causing catastrophic borehole failure.
The Economic Reality: Total Cost of Ownership
| Feature | Class 6 Casing | Class 10 Casing |
|---|---|---|
| Material | Recycled / Mixed | 100% Virgin PVC |
| Wall Thickness | Approx. 6mm | 10mm (High Density) |
| Design Lifespan | 5–15 Years | 50+ Years (Lifetime) |
| Risk Factor | High (Collapse) | Minimal (Shielded) |
Pro Tip: If a Class 6 borehole collapses, you lose the drilling fee, the casing, and potentially a $1,000+ pump. Class 10 is an insurance policy for your water future.

Fact 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.
Fact 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).
Fact 3: There Is No 100% Guarantee
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.
Fact 4: Siting 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.
Fact 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.
