Rock coring and extended-depth drilling · UAE
Arasar provides rock coring, deep hole drilling and extended-depth concrete drilling from Dubai for mass foundations and complex civil structures across the UAE where conventional drilling loses reach, cooling or alignment.
The method
As drilling depth increases, small errors at the rig become large deviations at the exit point. Barrel extension, reinforcement, spoil removal, cooling and the stability of the drilling assembly all influence the final bore.
Deep coring therefore begins with an engineered setup. Rig position and anchorage are verified, the bore path is coordinated with the structure, and the drilling sequence includes planned breaks for barrel management and inspection. Specialist hydraulic systems can be configured for demanding horizontal, inclined or vertical work.

Arasar provides rock coring and deep hole drilling from Dubai for suitable foundation, mass-concrete, civil and infrastructure work across the UAE. Bore depth, diameter, angle, rock or concrete condition, rig anchorage, cooling, spoil and core recovery are reviewed as one method.
Tooling, power, cooling and recovery stages are selected around the actual material, reinforcement and required sample or penetration.
A rigid setup, verified entry axis and staged checks limit accumulated deviation over long horizontal, inclined or vertical bore paths.
Core sections, water, spoil, breakthrough risk and completed bore records are managed around access and the receiving project requirement.

Technology creates value only when it is integrated with the structure, the work environment and the required end state.
Rigid setup and staged verification limit deviation over an extended bore path.
Hydraulic systems and barrel configurations are selected for depth, reinforcement and orientation.
Core sections, spoil and cooling water are controlled throughout the drilling cycle.
Project workflow
Each stage produces the information needed to release the next, keeping engineering and site execution aligned.
Define entry, exit, diameter, depth, tolerances and structural constraints.
Create a stable anchored platform and verify the initial drilling axis.
Extend the barrel progressively, recover cores and monitor alignment and cooling.
Confirm breakthrough, bore condition and compliance with the required geometry.
Typical deliverables
Technical questions
Final methods and capacities are confirmed after a project-specific site assessment.
There is no single threshold. The term applies when bore length, orientation or access requires extension barrels, specialist guidance and controls beyond standard coring practice.
A stable rig, accurate initial set-out, compatible barrel assemblies and staged checks are used. The achievable tolerance depends on the structure and bore length.
Diamond systems can pass through reinforcement, but steel density affects tooling, production and heat. Available drawings and scanning help the team plan the most reliable path.
Yes, for suitable civil, foundation and infrastructure scopes. Rock type, bore diameter, depth, angle, access, alignment tolerance, core recovery and water or spoil controls are reviewed before equipment and method are confirmed.
Standard core drilling forms defined circular penetrations at conventional depths. Deep hole drilling requires extended barrels, more rigid alignment control, staged core recovery and additional cooling or spoil management because small setup errors increase over the longer bore path.
