Dival – your partner for difficult underwater tasks.


Underwater work, as defined by the Law of October 17, 2003 on Underwater Work, refers to activities performed below the surface of water by individuals equipped with diving gear or in an environment with artificially elevated atmospheric pressure. It also includes the activities of personnel working on the surface who are responsible for organizing underwater tasks and operating equipment at the underwater work base.


DIVAL responds to the challenges of all types of underwater work, including underwater welding, concrete cutting, sealing injections, and drilling. As DIVAL, we also conduct repairs and inspections of the underwater parts of vessels, as well as underwater inspections using ROV (Remotely Operated Vehicles). At DIVAL, we are equipped with the right tools and proven materials, and we produce audio-visual documentation of the underwater work we perform

.

Our underwater work is carried out by a qualified and experienced team that meets all safety standards and requirements, holding up-to-date certifications and approvals. DIVAL is committed to providing high-quality services, and we invite you to collaborate with us!

Diving approvals

The safety of water infrastructure requires regular technical control and reliable underwater documentation. DIVAL provides professional diving approvals and technical inspections of hydrotechnical structures, supporting owners and managers in maintaining safe operation of their facilities.

Installation of valves

DIVAL provides precise installation of valves, stoplogs and temporary closure systems on dams, weirs, hydropower facilities and other hydrotechnical structures. These works are essential when water flow must be controlled, limited or temporarily stopped to allow safe repair or maintenance operations.

Diving assists

DIVAL provides professional diving assistance for companies and organizations carrying out works on or near water. We support engineering projects, construction works, inspections, events, film productions and emergency operations requiring experienced commercial divers.

Polishing of ship propellers

Propeller polishing is an effective underwater service that supports the efficiency and performance of vessels. A clean and smooth propeller surface reduces resistance, improves propulsion efficiency and may contribute to lower fuel consumption.

Underwater work on floating units

DIVAL provides specialist underwater works on ships, barges and other floating units without the need for docking. Our services include underwater hull inspections, propeller and rudder cleaning, technical assessments, emergency repairs and removal of minor defects below the waterline.

Drilling underwater

Underwater drilling is used in hydrotechnical engineering, marine construction and industrial projects where precise holes must be made below the waterline. It can be required for anchoring, installation works, sampling, repairs or preparation of structural connections.

Core drilling

DIVAL performs underwater core drilling for material sampling, technical assessments and the creation of technological or anchoring holes in hydrotechnical structures. This method allows precise drilling while limiting vibration and reducing the risk of damage to the inspected or repaired structure.

Core drilling is used in diagnostics, repairs, modernization and installation works. We adapt the equipment and drilling method to the material, location, depth and technical requirements of the project.
