BOREHOLE EXPERTISE • 2026 EDITION

Selecting the Right Borehole Casing: Class 6, 9, 10 & Double Casing Options

Investing in a borehole is a lifetime commitment to reliable water security, and the durability of your well depends on one crucial factor: The Casing. At Gi Glo Solar and Boreholes Zimbabwe, we prioritize client education to ensure every borehole installation remains structurally sound, collapse-free, and fully protected from surface contamination.

Our high-quality casings, combined with professional drilling and installation, guarantee long-term performance for homes, farms, and commercial operations across Zimbabwe, giving you peace of mind and uninterrupted access to clean water.

Understanding Borehole Casing

Protection, Stability, and Purity

Borehole casing is essentially the "skeleton" of your well. It consists of high-quality PVC pipes inserted into the borehole after drilling to prevent the surrounding soil and rock from collapsing inward. Beyond structural integrity, strong casing acts as a shield, preventing surface contaminants and pollution from entering your clean groundwater supply.

Modern boreholes use PVC (Polyvinyl Chloride) because it is resistant to corrosion, lightweight for installation, and durable enough to last decades underground without contaminating the water quality.

Casing Classes: 6, 9, and 10

Decoding Pipe Thickness and Strength

When getting a quote for borehole drilling in Zimbabwe, you will often see "Class" mentioned. This refers strictly to the wall thickness of the pipe. The higher the class, the thicker and stronger the pipe.

Class 6 Casing

The industry minimum. Normally used for standard pricing in stable rock areas.

Class 9 & 10 Casing

Recommended: Much thicker walls. Reduces the risk of future collapse significantly.

Expert Note: Gi Glo recommends Class 9 or 10 for any long-term residential or commercial investment to ensure the borehole survives earth movements and soil pressure.

The Double Casing Necessity

Managing Unstable and Weak Soil Conditions

Double casing involves inserting a smaller pipe (e.g., 140mm) inside a larger starter pipe (e.g., 180mm). This is essential in areas with "weak soil" or collapsing formations.

  1. Dynamic Decision: The need for double casing cannot always be determined beforehand; it depends on the soil conditions found during drilling.
  2. Targeted Application: It is typically only applied to the weak sections of the borehole, not the entire depth.
  3. Universal Requirement: If the ground is unstable, double casing may be required regardless of whether you chose Class 6 or Class 10 pipes.
