Why Choose Us?

Safe Ground Investigation & Surveys

  • Strategic Oversight: We coordinate and manage comprehensive desktop studies and on-site GPR (Ground Penetrating Radar) surveys, ensuring clarity before breaking ground.

  • Statutory Compliance: Full procurement of Statutory Utility Packs combined with on-site verification to protect your project from legal and physical risk. PAS 128 Category Surveys.

  • Precision Mapping: Utilising non-invasive GPR technology to detect buried utilities and anomalies, providing a digital blueprint of what lies beneath.

  • Risk Mitigation: Minimise project delays and eliminate the "unknowns" that lead to emergency repairs and budget overruns.

Safe Suction Excavation & Ground Removal

  • The Safest Method: Our suction excavation technology is 100% non-invasive, virtually eliminating the risk of utility strikes and infrastructure damage common with mechanical or manual digging.

  • Long-Distance Reach: Equipped with some of the longest-reach excavators in the UK, we can operate at distances of up to 120m, reaching inaccessible areas other machines can't access.

  • Operational Efficiency: Faster than manual digging and cleaner than traditional machinery; we remove ground material directly into the on-board tank for immediate site clearance.

  • Cost-Effective Accuracy: Minimise manual labour costs and project downtime through high-speed, precision removal of soil, ballast, and debris.

  • Industry-Leading Reliability: Delivering consistent on-site performance with a focus on safety-first protocols and around-the-clock availability.

  • The Dino Mega Vac features a suction hose with an impressive reach of 120 meters, allowing access to areas that are impossible for traditional excavators to reach. This makes it ideal for confined spaces, urban environments, and sensitive areas where conventional digging would be risky or impractical.

  • The Dino Mega Vac is a high-performance suction excavation machine designed for safe, efficient, and non-destructive digging. It uses powerful vacuum technology to remove soil, debris, and other materials from excavation sites, offering a safer alternative to traditional digging methods.

  • The machine is capable of handling a wide variety of materials, including:

    • Soil and sand

    • Gravel and stones

    • Mud and sludge

    • Industrial waste

    • Water and other liquids

  • Yes. Suction excavation is a non-invasive and non-destructive method, making it a safe choice for digging around underground utilities like gas lines, water pipes, and electrical cables. The Dino Mega Vac minimizes the risk of accidental damage compared to mechanical excavation.

  • Non-destructive: Safer for sensitive areas with buried utilities.

    Less disruptive: Minimizes mess and environmental impact.

    More precise: Allows for targeted excavation, reducing unnecessary digging.

    Faster setup and cleanup: Saves time and labor costs.

  • The Dino Mega Vac is designed with multiple safety features, including:

    • Advanced filtration systems to handle hazardous materials

    • Remote-controlled operation for safe distance handling

    • Overload protection systems to prevent equipment damage

    • Emergency shut-off mechanisms

  • Ground Penetrating Radar (GPR) is a non-invasive survey method used to map buried utilities and infrastructure without breaking ground. By identifying the exact location of underground assets early, you eliminate the risk of utility strikes, prevent costly project delays, and ensure a safer working environment for your team.

  • We coordinate and manage full Statutory Utility Packs and desktop studies as part of our comprehensive survey process. This ensures that all on-site works are backed by legal documentation and physical verification, protecting your business from the risks associated with unauthorized or uninformed excavation.

  • Yes. Our surveys are designed for maximum precision in complex environments, including highways, rail, and industrial sites. We use advanced, non-destructive technology to provide a digital blueprint of what lies beneath, allowing for effective project planning even in the most challenging locations.

  • A desktop study involves procuring existing utility records and maps to understand known infrastructure. An on-site GPR survey uses real-time radar technology to verify those records and detect "unknown" or undocumented assets that maps often miss. Combining both provides the highest level of authority and safety for your project.

  • Precision mapping removes the "guesswork" from excavation. By knowing exactly where to dig, you minimize manual labor, reduce the need for exploratory trial holes, and prevent emergency repair costs caused by accidental damage to buried utilities—directly impacting your project's bottom line.

  • Specialised ground investigation requires a strategic, evidence-led approach that general contractors often lack. We provide authority-level insights, non-invasive technology, and ongoing support that transform your site investigation from a simple "task" into a strategic business asset that guarantees safety and compliance

What is Suction Excavation?

Suction excavation enhances excavation efficiency while minimising health and safety risks (CDM 2015). Instead of traditional machinery for soil removal, it uses a high-powered suction system to safely extract both solid and liquid materials from the site.

Why Use Vacuum Suction Excavation?

Our New Dino Mega Vac?

If your suction works are at extreme depth or distance then the Dino Mega Quad Fan system may offer the solution to your needs.  Twin or quad fan configuration making it flexible enough for standard as well as extreme suction works.
