Borehole Sleeving

Borehole sleeving offers several options, including steel or PVC casing, or a combination of both. Steel casing enhances structural stability, effectively preventing borehole collapse in areas with unstable soil conditions. It extends down to bedrock depths, ensuring borehole integrity in unstable soil.

Once steel casing secures stability, subsequent steps may involve PVC casing or none, depending on client preferences. Opting for PVC casing brings advantages such as increased stability and protection for pumps against weathering, corrosion, and aging.

The casing installation process unfolds in two phases. Initially, steel casing takes precedence upon confirming the presence of hard rock. It provides essential structural reinforcement to counteract unstable soil conditions.

Sequential Casing Installation Process

Following successful steel casing installation and borehole stability confirmation, the subsequent phase introduces PVC casing. This step aligns with borehole success, signifying its ability to provide a reliable water supply.

In other words, steel and PVC casing serve distinct roles in borehole construction. Steel casing effectively manages soil instability and maintains borehole integrity up to the point where hard rock is encountered. However, PVC casing is chosen for added stability and equipment protection, customized to client preferences.

The installation of these casings follows a sequential approach, with steel casing preceding PVC installation. This sequence unfolds once borehole success has been established, ensuring a consistent and dependable water supply.
