    Grundomat 45 Extra Short mole: trenchless installation notes for UK site engineers

    First reported on The Construction Index

    30 Second Briefing

    Tracto has launched the Grundomat 45 Extra Short mole in the UK, a trenchless pipe-laying tool just 800mm long and 8kg in weight for sites with severely constrained entry and exit pits. The pneumatic mole delivers 580 impacts per minute and is offered in either high-strength steel or hardened alloy steel, targeting service connections and short bores where standard-length tools are impractical. An initial batch of 40 units is stocked at Tracto UK’s Bedford headquarters, with early uptake from groundworkers, contractors and utility installers.

    Technical Brief

    • Pneumatic mole operates by percussively displacing soil, forming a bore without bulk excavation.
    • Shortened 800 mm body directly reduces pit length, useful near buried services or confined chambers.
    • Reduced excavation volume cuts spoil handling, cart-away, and reinstatement quantities on utility jobs.
    • Lower reinstatement footprint benefits paved, landscaped or trafficked surfaces where full-width trenching is constrained.
    • 8 kg unit weight allows manual handling by a single operative, easing deployment in tight access points.
    • High-strength versus hardened alloy steel options allow matching tool wear resistance to abrasive ground conditions.

    Our Take

    An impact rate of 580 blows per minute on such a short mole suggests it is aimed at maintaining bore accuracy over short shots in mixed ground, which is often a challenge on small utility connections and service laterals compared with longer, heavier impact moles.

    Stocking an initial 40 units at Tracto UK's Bedford HQ indicates Tracto expects near-term demand from multiple contractors rather than a niche, made-to-order tool, which could normalise use of small-diameter trenchless installations on minor projects rather than reserving them for specialist crews.

    National Grid TBM under the Thames: tunnelling design and risk notes for engineers

    A 271.5‑tonne Herrenknecht Mixshield TBM, Caroline, has started driving a 2.2km electricity cable tunnel with a 4m internal diameter beneath the River Thames in Essex for National Grid’s Grain to Tilbury project, delivered by the Ferrovial BEMO joint venture. The drive will pass through variable Thames estuary ground conditions between 35m‑deep launch and reception shafts of 15m and 12m diameter, with tunnelling continuing into 2026 and overall scheme completion targeted for 2029. The new tunnel will replace the 1969 Thames Cable Tunnel and carry new high‑voltage circuits between Grain and Tilbury substations.

    Panama Canal Mixshield undercrossing: design and tunnelling lessons for engineers

    A 13.46m diameter Herrenknecht Mixshield TBM has broken through into the future Balboa station on Panama Metro Line 3 after completing the first-ever TBM undercrossing of the Panama Canal at depths exceeding 60m below sea level. The 5,600kW, 26,616kNm machine, fitted with an accessible cutterhead and more than 4,500 sensors linked via the Herrenknecht.Connected platform, has achieved peak advance of 150 segment rings (about 300m) per month through mixed sandstone, tuff, breccias and basalt. Around 1.5km of the 4.5km twin-track tunnel remains to final breakthrough.

    Hudson Tunnel funding deadline: schedule and risk takeaways for project teams

    Federal funding for New York’s US$16bn Hudson Tunnel Project has been frozen, forcing the Gateway Development Commission to suspend works from 6 February after spending over US$1bn and employing about 1,000 site workers. A Manhattan federal judge has issued a temporary restraining order, giving the administration until 5 p.m. on 12 February to restore reimbursements or appeal, while contractors warn that demobilisation, resequencing and remobilisation will add cost and delay. Sites are now in “safe-pause” mode, with dewatering, ground support and environmental monitoring maintained, and assembly of two Herrenknecht TBMs in New Jersey likely to slip beyond the planned spring 2026 launch without funding certainty.
