Work to the repair drawing
Removal depth, edges, reinforcement and embedded services come from the repair information and site markings. The provider checks how equipment reaches the work face and where water, fines and broken concrete will be caught. A trial section gives the site inspector or repair team a real exposed surface to inspect. Hydrodemolition services can then work to the designed repair boundary.
The marked drawing gives the removal depth, edges and reinforcement that must remain. Any ducts, fixings or embedded services are added before the equipment position is chosen.
Runoff capture and concrete-debris handling are prepared around the same marked section.
Repair drawings and site markings establish the removal depth, edges and reinforcement to retain. Equipment position, runoff collection and debris handling are planned around that boundary before the representative area is opened. The repair team checks the opened trial against the drawing before water jetting continues across the marked concrete.
A trial section shows how the concrete responds around reinforcement. Work then advances to the agreed depth while water and arisings are recovered.
The exposed concrete is handed to the repair team or site inspector for the check specified in the job details.
Hydrodemolition may form one part of a wider construction and civil engineering programme. Where people cannot safely work close to the cutting head, remote water jetting may be worth considering. Send the marked drawings so the provider can review the access.
Hydrodemolition is planned from drawings, inspection findings and clearly marked removal areas. The job details must state whether the aim is to remove defective concrete, expose reinforcement, prepare an edge or reach a depth set by the repair design. Embedded services, post-tensioning and nearby sound material must be identified before work begins.
A trial area shows how the concrete responds and what surface remains for inspection. The Health and Safety Executive describes robot-mounted water jetting for concrete removal as an alternative to percussive breaking in an appropriate bridge repair example. Each project still follows its own repair design and site controls.
Access, runoff and repair handoff
Equipment position, edge protection, exclusion areas and the path taken by hoses need to fit the active construction site. Runoff can carry concrete fines and fragments, so the collection and treatment route must be agreed with the principal contractor rather than left to the surface-water system.
After removal, the exposed area is presented for the inspection defined by the repair team. Any further removal is a separate instruction based on what is visible. Send the marked drawings, access photographs and repair requirements when requesting our hydrodemolition services.
Send the repair drawing, survey information, marked photographs and any detail showing reinforcement or embedded services. Add the site access route, working height, runoff arrangement and the inspection required after removal.
If the depth or concrete condition is uncertain, say so. The first review can identify where a trial or closer site review is needed before the removal method and quotation are confirmed.
Reinforcement position and condition must be understood before removal. The method and trial area are then planned around what needs to be exposed and retained.
The required depth, marked limits and acceptance checks are agreed in the job details. Conditions found during the trial can affect the final method.
Responsibility for water and concrete debris is agreed before work starts. The plan covers capture, separation, temporary storage and the site’s authorised disposal route.
