Home Services Case Studies About Careers Apprenticeships News Contact Maintenance Excavations We can undertake maintenance excavations to expose split-couplings and sunken jointing chambers, to enable our engineers to undertake work before backfilling and reinstatement. Duct Blockage Clearance Where underground ducts become blocked, damaged or drop – preventing cables from being installed – our teams excavate to expose the damage duct so that a repair can be carried out before backfilling and reinstatement. Trial Holes Our excavation teams are able to undertake trial hole excavations to investigate the composition and structure of the subsurface before undertaking further major works. Cabinet Capacity Upgrades & Reshell We can upgrade the capacity of streetside telecommunications cabinets by upgrading the cabinet shell or by re-shelling existing cabinets. In addition our teams are experienced in fitting side-pod extensions to existing cabinets such as stand-off and G.fast side pods to existing PCP cabinets and HD side pods to DSLAM cabinets. Gully Emptying & De-silting Where jointing chambers and manholes are full with contaminated water, we can remove and dispose of waste water using jet vac tankers and to licensed waste sites in accordance with current legislation. High Pressure Water Jetting Using high pressure water jetting we are able to clear silt and mud build up within the underground duct network, successfully clearing the blockage without the need for costly and timely excavation work.
