Due to their design, our flat jacking equipment is not only light in weight but require a minimal installation gap or just a few centimetres. All our Hydra Capsule flat jacks are fully designed and manufactured within our new purpose built warehouse facility. The installation of our flat jacking equipment is carried out in-situ and inflated using a high pressure injection system, epoxy resin or cementitious grout can be injected, but grout filled units are normally recommended in order to meet the current day environmental and fire regulations.
This application is normally implemented to new supporting steelworks during structural alterations , underpinning or bridge bearing replacement operations requiring pre-stressing to avoid excessive deflections taking place when any temporary supports are removed. Hydra-Capsule provide a full design, in-house manufacturing and flat jack installation service offered throughout the UK and Internationally. Bespoke units can also be manufactured to suit customers particular requirements, please contact us for further details.

A14 Huntingdon Bridge Viaduct Strengthening. Hydra-Capsule have recently completed a major synchronised bridge jacking and grout bags works for the viaduct half joint strengthening. The project involved working with the Highway Agency and Network Rail hand-in-hand due to the unusual bridge structures. The A14 bridge viaduct was part of the A14 Ellington to Fen Ditton major improvement scheme, but due to the ongoing deterioration of the half joints on the central span of the bridge, without intervention, the bridge would be incapable of of carrying the type and volume of traffic that uses the A Hydra-Capsule were appointed to design and manufacture 84 number bridge jacking 50 tons capacity screwed ram locking collar hydraulic jacks.
Which allowed all jacks to be individually controlled by our own computerised system, using precise load and movement displacement LVDTs real time monitoring units at each installed strengthening beam position. Once completed, Hydra Capsule installed custom-made grout bags which were inserted at each bearing location and inflated by our grout pump, to wedge the gap.
Once the grout bags had cured and reached the specification compressive strength, the hydraulic jacks were energised, locking collars untightened and all jacks loads were de-energised under.
