Underwater concrete moulding and formwork involves installing temporary or permanent moulds and supports to allow concrete to be placed and shaped correctly below the waterline.
Main activities:
Installation and positioning of underwater formwork, moulds, frames, and reinforcement.
Placement of specialised concrete or repair materials suitable for underwater conditions.
Repair of cracks, damaged concrete, voids, erosion, and deteriorated structural sections.
Restoration of piles, foundations, quay walls, docks, seawalls, bridge structures, and other submerged concrete structures.
Removal of loose or damaged material and preparation of surfaces before repair.
Underwater concrete repairs:
Restore the strength, stability, and integrity of damaged structures.
Seal cracks and prevent further water penetration.
Replace missing or deteriorated concrete.
Protect reinforcement from further corrosion.
Main benefits:
Repairs can often be performed without dewatering or taking the structure out of service.
Minimises operational downtime.
Extends the service life of marine concrete structures.
Provides a cost-effective solution for submerged repairs.
