Trenching & Excavation
Precision micro-trenching, heavy excavation, and duct installation for utility and telecom networks.
Engineering Excellence in Trenching & Excavation
Thobal provides specialized trenching and civil excavation services for underground telecommunications, electrical duct banks, and fiber network infrastructure. Utilizing advanced trenchers, micro-trenching technology, and directional drilling (HDD), we minimize asphalt disruption while excavating precise cable trenches through rocky terrain, urban roadways, and industrial zones. Works include backfilling, compaction, handhole/manhole placement, and complete asphalt reinstatement to municipal standards.

Scope of Work & Deliverables
Dedicated engineering supervision and full-scope execution across every stage of trenching & excavation.
Our civil trenching scope covers utility line detection, municipal permitting, precision trenching, HDPE duct bank laying, precast manhole installation, and complete asphalt road restoration.
Using specialized micro-trenching and trenchless HDD techniques, we accelerate network rollouts in dense urban environments without disrupting surface traffic or surrounding infrastructure.
Execution protocols strictly enforce Ground Penetrating Radar (GPR) utility scanning, MOMRA-certified Class-A aggregate backfilling, and 95% Modified Proctor density compaction testing. Final deliverables comprise municipal road opening permits, soil compaction test certificates, precast manhole as-built drawings, and smooth hot-mix asphalt reinstatement ready for immediate traffic clearance.
Utility Detection & GPR Survey
Ground Penetrating Radar (GPR) scanning to map existing underground utilities and prevent service strikes.
Permitting & Traffic Management
Securing municipality excavation permits, traffic detour plans, and safety barricades.
Trench Excavation & Micro-Trenching
Precision trench cutting (100mm to 600mm width) using mechanical wheel trenchers and excavators.
Duct Laying & Concrete Encasement
HDPE/PVC duct bank laying, spacer positioning, sand bedding, and lean concrete encasement where required.
Manhole & Chamber Installation
Placement of precast concrete telecom manholes, joint boxes, and heavy-duty iron cover frames.
Backfilling & Road Reinstatement
Class-A aggregate backfilling, sub-base compaction, surface asphalt paving, and line marking.
