Professional Underwater Demolition & Dismantling Services

Underwater demolition is a specialized construction and demolition activity involving the controlled removal, cutting, breaking, dismantling, or modification of structures located partially or completely below water.

Unlike conventional demolition, underwater work requires specialized planning, equipment, trained personnel, diving operations where applicable, and strict control of underwater hazards. Visibility, water depth, current, submerged structures, access, marine traffic, and environmental conditions can significantly affect the demolition methodology.

Malik Trading and Demolition provides specialized Underwater Demolition and Underwater Dismantling Services for infrastructure, industrial, marine, bridge, dam, water-retaining, and other submerged structures. Our approach combines project-specific planning, suitable underwater equipment, controlled removal techniques, safety procedures, debris management, and site clearance.

What Is Underwater Demolition?

Underwater demolition involves the removal or modification of concrete, reinforced concrete, steel, masonry, foundations, piles, bridge components, marine structures, and other submerged construction elements.

Depending on the project, underwater demolition may involve:

• Underwater Concrete Breaking
• Underwater RCC Demolition
• Underwater Concrete Cutting
• Underwater Diamond Cutting
• Underwater Pile Breaking
• Pile Cropping
• Underwater Foundation Demolition
• Bridge Pier Demolition
• Submerged Structure Dismantling
• Marine Structure Demolition
• Dam Structure Modification
• Underwater Debris Removal

The selected method depends on the structure, water depth, accessibility, material, reinforcement, environmental conditions, and project requirements.

Where Is Underwater Demolition Used?

Underwater demolition can be required across a range of infrastructure and industrial projects.

Bridges & Flyovers

Underwater work may be required for bridge piers, foundations, pile caps, submerged concrete members, and other components located below water level.

Dams & Water Structures

Modification, repair, replacement, or removal of selected submerged concrete elements may require controlled underwater demolition techniques.

Ports & Marine Structures

Underwater demolition can be used for marine structures, foundations, platforms, damaged concrete components, and other submerged construction elements.

Pile Foundations

Existing piles may need to be broken, cropped, cut, or removed during reconstruction, expansion, or replacement projects.

Industrial Water Facilities

Industrial plants may contain submerged foundations, intake structures, water channels, cooling-water systems, and other structures requiring underwater modification or demolition.

Rivers, Canals & Reservoirs

Structures located in rivers, canals, reservoirs, and other water bodies may require specialized underwater demolition and debris removal.

Our Underwater Demolition Process

1. Site Inspection & Project Assessment

Before starting underwater demolition, the project area is assessed to understand the submerged structure and surrounding conditions.

The assessment may consider:

• Water depth
• Structure dimensions
• Concrete and reinforcement
• Steel components
• Water current
• Visibility
• Access conditions
• Submerged obstacles
• Nearby structures
• Marine traffic
• Environmental requirements

The information is used to develop an appropriate work methodology.

2. Structural Assessment

The existing submerged structure should be evaluated before demolition begins.

The team identifies the structural components that need to be removed and determines an appropriate demolition sequence.

Particular attention is given to structural stability and the possibility that removing one component could affect another.

3. Work Area Preparation

The underwater work area is prepared according to project requirements.

Depending on the site, this may involve:

• Access arrangements
• Work-zone marking
• Surface-level exclusion zones
• Temporary barriers
• Equipment positioning
• Diving support systems
• Water-level or flow management
• Communication arrangements

Where applicable, water flow and surrounding operations may need to be controlled before demolition.

4. Underwater Cutting & Breaking

The appropriate underwater demolition technique is selected based on the structure and project requirements.

Possible methods include:

• Hydraulic Breaking
• Underwater Concrete Cutting
• Diamond Cutting
• Wire Saw Cutting
• Hydraulic Shearing
• Pile Breaking
• Mechanical Dismantling
• Controlled Removal

For reinforced concrete, cutting and breaking methods may be combined to separate concrete and reinforcement efficiently.

5. Reinforcement & Steel Cutting

Underwater RCC structures may contain significant reinforcement steel.

After concrete is exposed or separated, reinforcement can be cut using suitable underwater equipment.

Steel structures and embedded components can also be dismantled according to the approved sequence.

6. Controlled Material Removal

Removed concrete, steel, and other materials need to be controlled during underwater operations.

Depending on the size and location of the material, removal may involve:

• Lifting Equipment
• Cranes
• Winches
• Slings
• Material Handling Systems
• Controlled Recovery Equipment

The objective is to prevent uncontrolled movement of demolished material.

7. Underwater Debris Removal

Demolition debris can accumulate around the work area and may interfere with subsequent construction or inspection.

Our work can include underwater debris collection and removal as part of the project scope.

Materials can be recovered and transported to the designated location according to project requirements.

Safety in Underwater Demolition

Underwater demolition presents hazards that differ from conventional land-based demolition.

Potential risks can include:

• Strong Water Currents
• Poor Visibility
• Entrapment
• Falling Materials
• Heavy Equipment
• Diving Hazards
• Electrical Equipment
• Communication Limitations
• Marine Traffic
• Structural Instability
• Suspended Debris

A project-specific risk assessment, method statement, competent personnel, suitable diving arrangements where applicable, communication procedures, emergency planning, and appropriate equipment are essential.
