Solutions in hydrodemolition

With our hydrodemolition techniques, we can remove contaminated concrete, refractory material and grout while retaining the surrounding structures. With water under high pressure, we spray away the concrete between the rebar and can remove old finishing layers, clean contaminated surfaces and even cut through entire concrete or steel columns. We use our own set of machines with ultra-high-pressure machines, driven by experienced operators using robotics and with a minimal load on people and the environment. If desired, the water drawn from a nearby source can be collected and purified before it is discharged. No carcinogenic quartz dust is released with hydrodemolition. That makes this technique a very sustainable choice for the demolition or treatment of concrete and steel structures.

Grout Removal

Grout Removal

When applying grout (cement) in, for instance, wind turbines, ‘segregation’ may occur. As a consequence, the desired quality is not being reached. Replacing the entire grout layer often is the only option to achieve a satisfactory end result.

Treating waste water

Treating waste water

In recent years, ADS has invested greatly in the sustainability of the processes. Because our techniques are all about hydropower, we are focused on the sustainable use of this important natural source.

Cleaning or pre-treating concrete

Cleaning or pre-treating concrete

When cleaning a concrete or steel surface to prepare for treatment with paint, coating, epoxy or polyurethane, people often choose sandblasting. This involves the risk of damaging the underlying structure and makes dust nuisance almost unavoidable. The high pressure water technique is a great alternative.

Removing refractory concrete

Removing refractory concrete

Removing refractory concrete requires a specific method. The density and hardness make these materials difficult to demolish with traditional demolition methods, often resulting in damage to the underlying steel structures. Hydrodemolition is extremely effective and can be performed in limited spaces using robotics, so that the safety of the employees is assured.

High pressure cutting technique ‒ hydro-cutting

High pressure cutting technique ‒ hydro-cutting

The latest water cutting machine (hydro-cutters) cut through steel plates and even through columns made of concrete and steel. If you want to cut something that cannot be moved, such as a pylon of a building, bridge or overpass, then we can carry out the cutting work on the spot for you with our mobile water cutting machines.

Rebar-saving demolition

Rebar-saving demolition

Every year, 13 million m³ of concrete is processed in the Netherlands. Occasionally, something goes wrong. We regularly see defects, even in brand-new structures. Cracks, gravel nests, leaks, flaking. In addition, many older structures are in need of renovation. Hydrodemolition can provide a good contribution to that.
