Concrete Removal with High-Pressure Water

Removing Concrete with High-Pressure Water – Clean, Precise, Sustainable

Concrete removal is a crucial step in many construction and renovation projects – whether it’s repairing structures, removing damaged layers, or exposing reinforcement. KAMAT offers you a state-of-the-art solution for this: concrete removal with high-pressure water – efficient, vibration-free, and environmentally friendly.

Why remove concrete with water?

Many construction companies still rely on mechanical methods such as chiseling, milling, or grinding—but these methods are loud, generate a lot of dust, and put stress on adjacent structures due to vibrations.

The alternative: water instead of a hammer.

With KAMAT’s high-pressure water jet technology, you benefit from:

• Precise concrete removal—from a few millimeters to several centimeters
• Vibration-free work – ideal for sensitive or listed buildings
• Dust-free application – particularly important indoors and during ongoing operations
• Gentle on materials – no risk to adjacent components
• Efficient preparation for further renovation measures (e.g., coatings, repairs)

Concrete Restoration with High-Pressure Technology – Preserves Structure and is Economical

Successful concrete restoration begins with the right method for removing old or damaged concrete areas. KAMAT’s high-pressure technology enables:

• Restoration of concrete surfaces in underground garages, industrial facilities, bridges, or tunnels
• Roughening of concrete for new coatings
• Selective removal of concrete in damaged areas
• Exposure of reinforcement for structural repair

Compared to conventional methods, water jet technology offers clear advantages:

• No microcracks due to mechanical impact
• No thermal influence as with milling or flame cutting
• No dust that is hazardous to health

Result: A clean, load-bearing concrete surface that is optimally prepared for all further repair steps.

High-Pressure Water Jetting — How Does Concrete Removal with Water Work?

When removing concrete with high-pressure water, a concentrated water jet with a pressure of up to 3000 bar is directed at the concrete surface. Depending on the nozzle technology, pressure, and amount of water, the surface can be:

• cleaned
• roughened
• removed selectively or over a large area
• exposed down to the reinforcement

The structure remains intact – no vibrations, no component failure. This is an enormous advantage, especially when renovating existing buildings.

Even thin layers (e.g., 1 cm screed) can be removed efficiently – a common challenge in interior work or when leveling floors.
