Specialised underwater works
Underwater concreting
Underwater concreting for foundations, repairs and structural applications.
Underwater concreting is an essential technique in the construction and repair of foundations, quay walls, and other hydraulic infrastructure. Our team has the experience and specialist knowledge to perform underwater concrete works according to the highest quality standards. We work with special concrete mixes that are resistant to washout and cure optimally underwater. From small repairs to large-scale foundation works: we ensure a durable and reliable result.
Sinking of shafts
Controlled sinking and positioning of shafts in wet conditions.
Sinking of shafts requires precision and experience. We handle the controlled sinking of concrete or steel shafts to the desired depth, even in complex soil conditions. Our divers continuously monitor the process to ensure correct positioning. This technique is applied in the construction of pump stations, inspection shafts, and other underground structures in wet conditions.
Caisson placement
Installation and positioning of caissons for civil and maritime projects.
Caissons form the foundation for many maritime and civil structures. We handle the installation, transport, and positioning of caissons at the desired location. Our divers check underwater preparation, guide the sinking process, and ensure proper sealing and foundation. Whether it concerns port infrastructure, locks, or bridge piers: we deliver tailored craftsmanship.
Repair and overhaul
Underwater repairs and overhaul works on concrete and steel structures.
Concrete structures and steel constructions underwater are subject to wear, corrosion, and damage. Our specialists perform inspections, repairs, and overhaul works on quay walls, bridge piers, lock gates, and industrial installations. We use advanced techniques for concrete repair, cathodic protection, and underwater welding. Regular maintenance significantly extends the lifespan of your infrastructure.
General diving works
A range of execution-focused diving works tailored to project needs.
In addition to our specialised services, we carry out a wide range of general diving works. This includes underwater inspections, removing obstacles, installing underwater equipment, salvage operations, and technical support for dredging works. Each project is approached on a bespoke basis, with attention to safety, efficiency, and the specific requirements of the client.
Welding and torch cutting
Underwater welding and torch cutting for repairs, dismantling, and steel-structure modifications.
For projects where precision and reliability are critical, we perform specialised underwater welding and torch cutting. We support repairs, removal of damaged parts, and structural modifications on site. With experienced divers and the right procedures, we work safely and in control, even in complex conditions.
Core drilling
Accurate core drilling in concrete and steel, including underwater applications.
We perform core drilling for penetrations, inspections, and technical modifications in existing structures. Each bore is positioned and executed with attention to structural integrity and safety. This delivers clean openings and reliable results for civil and industrial applications.
