Borehole Drilling & Construction
State-of-the-art mud rotary, air rotary, and air percussion drilling techniques designed to access deep aquifers with optimal casing, screen placement, and gravel packing.
Borehole Drilling & Construction
State-of-the-art mud rotary, air rotary, and air percussion drilling techniques capable of reaching deep aquifers (up to 350m+) with optimal casing and gravel packing.
Built to withstand arid and semi-arid conditions across the Federal Member States, our drilling operations adhere to rigorous engineering and environmental standards. We ensure structural integrity, high yields, and long-term borehole operational resilience for community water supplies, agricultural irrigation, and commercial projects.
Scope of services
- Deep Aquifer Rotary Drilling: Advanced mud and air rotary drilling methodologies tailored to penetrate complex consolidated and unconsolidated lithological formations.
- Casing & Screen Installation: Installation of high-strength PVC or steel casings coupled with precision-slotted screens to maximize water inflow while preventing sand pumping.
- Gravel Packing & Well Development: Professional placement of graded gravel packs and air-lift development to clean the borehole walls, enhance permeability, and boost specific capacity.
- Sanitary Well Sealing & Headworks: Construction of sanitary concrete surface seals and secure wellheads to prevent surface contamination and protect groundwater quality.
- Initial Yield Testing & Disinfection: Pre-commissioning test pumping and chlorination to ensure water safety and verify immediate borehole performance.
