Ven-Tech Subsea Inspections offers a highly specialized, non-invasive solution for the permanent decommissioning and sealing of abandoned or out-of-service pipelines. Our Trenchless Pipe Sealing service utilizes proprietary robotic crawler technology to internally access pipelines and deliver expanding epoxy foam — eliminating the need for surface excavation, core drilling, or conventional intrusive abandonment methods.
This in-house developed system is designed specifically for scenarios where conventional access is not feasible, where surface disruption must be avoided, or where safety and environmental control are paramount.
Our system combines advanced CCTV-capable pipe crawlers with a custom-engineered expanding epoxy foam injection platform, allowing us to internally locate, assess, and seal off decommissioned pipes from within — without disturbing surface structures, pavement, or environmentally sensitive zones.
Using precision crawler deployment, we position our injection tool at the required termination point and remotely inject a high-performance, structurally bonding foam that expands and cures in-place to form a water-tight, gas-tight, and structurally secure seal.
• Ven-Tech’s Trenchless Pipe Sealing is ideal for:
• Municipal sewer and stormwater lines marked for deactivation
• Industrial process or utility conduits
• Abandoned intakes or outfalls
• Redundant fire suppression loops
• Crossings under buildings, roads, or environmentally protected areas
• Remote or confined infrastructure with no surface access
Conventional Drilling/Excavation | Ven-Tech Trenchless Solution |
|---|---|
Surface excavation required | No surface disruption (fully trenchless) |
Expensive, multi-day coring or trenching | Minimal equipment and labor |
Risk of damaging adjacent infrastructure | Non-invasive internal access |
Permitting and environmental delays | Fast deployment with low regulatory burden |
Limited access in confined or remote locations | Fully robotic access with live visual verification |
CCTV Navigation
Our operators deploy a crawler equipped with HD cameras and integrated lighting to inspect the interior of the pipeline and confirm termination point integrity.
Foam Injection Setup
The crawler positions the custom-built Ven-Tech foam injection module at the target location.
Epoxy Foam Sealing
A high-performance, expanding epoxy is injected and allowed to cure. The foam bonds to the inner pipe walls and expands into any voids, ensuring full mechanical and hydraulic closure.
Verification & Reporting
The seal is visually verified via live camera feed. Detailed footage, GPS location, and inspection documentation are included in a comprehensive final report.
