Concentric Casing System with Blocks - Mastering Soft Formation Drilling
Our concentric casing system with blocks is specifically designed for drilling in soft and unstable formations, making it ideal for applications such as geothermal wells, water wells, small-to-medium-sized grouting holes, and micro-piling projects.
To ensure exceptional durability and wear resistance, we subject our blocks to deep heat treatment processing. Additionally, our precision-engineered installation holes, created using advanced slow wire cutting techniques, guarantee seamless and hassle-free block usage.
