Hydro demolition machine uses high pressure water blasting equipment with hydrodemolition robot to remove the concrete from the building structure. This cleaning method will be easy to make the new cement without break the internal surrounding without any micro crack . It is widely used for road and bridge repairing . It is the new technology instead of the hydraulic hammer without cause any dust which is friendly and environmental .

Our range of ultra high pressure water blasting is ideally suited to hydrodemolition machine applications. This, coupled with our range of hydrodemolition accessories, ensures we can supply you with the complete package.

Hydrodemolition machine allows the safe, selective removal of concrete using ultra high pressure water.

There are many reasons for using hydro demolition robot including: no damage to rebar, no damage to underlying structure (no micro-cracks). The ability to access confined work spaces, and increased productivity over traditional techniques.

Hydrodemolition technology removes concrete using water pressure of up to 3000 bar, for long-lasting, high quality repairs. It creates no micro-cracks and leaves an ideal bonding surface for the fresh concrete.

Our hydro demolition robot travels over the concrete surface at a constant speed. Taking advantage of the concrete’s permeability to create an over pressure that breaks it apart. The automation of the Watex robots allow operators to easily execute both selective and non-selective removals.

Two removal methods with hydro demolition machine

Selective removal is the preferred method when only the deteriorated concrete needs to be removed. Hydrodemolition machine uses high-pressure water up to 22,000 psi (1500 bar) to selectively remove concrete at a predetermined quality level.

Non-selective removal is the preferred method when concrete needs to be removed to a predetermined depth, independent of the quality of the concrete. Watex robot uses high-pressure water above 22,000 psi (1500 bar).

No matter what option you choose, the high-pressure water jet technology will create a rough surface optimal for bonding of new concrete without creating any micro-cracks or damage to the remaining structure. At the same time, it leaves the rebar intact and cleaned from rust and corrosion.

With hydro demolition machine, you control the end result, always ensuring you meet the customer’s specifications

Hydrodemolition of concrete removal is a concrete removal technique utilizing high pressure water to remove deteriorated and old concrete. This process provides an excellent bonding surface for repair material and new concrete.

This increases safety for our workers in the field and production rate. Automation gives the operator the ability to set parameters according the thickness of the concrete and what is the hardness of the concrete

Hydro demolition machine robot

Watex hydro demolition equipment robot removes concrete by moving a high-pressure water jet over the surface in a pre-determined pattern at a pre-determined speed until the desired depth is reached. This is repeated over the entire surface in order to guarantee the same quality depth over the entire structure.

The remaining surface is free from delaminated or otherwise damaged concrete leaving a perfect surface for the new concrete to bond to.

In the process of hydrodemolition through robot , no micro cracks are introduced to the structure. Neither does hydro demolition machine cut the rebar. If there is corrosion on the rebars, it is removed in the hydrodemolition process.

By adjusting the proper pressure and flow rate, a more or less selective removal is achieved. Below a certain pressure level, the water will not cut the aggregate, only the paste bonding the aggregate together. Since the water follows the laws of hydraulics: easiest way out, the less competent concrete will be removed, and the stronger will remain. This is what is called “selective removal”.

Through the increasing pressure, the operation is still selective but when starting to cut the aggregate the selective zone decreases. That means that the surface may contain concrete with lesser strength that the surrounding material.

Overview of hydrodemolition machine

High pressure cleaning is the method by which a high pressure stream of water is used for old paint, rust, road marking ,rubber. Barnacle,asphalt removal or other heavy buildup without causing damage to the surface below it,it can be used the best way for for surface preparation and hydrodemolition.

This method is perfect for internal washing and external surface cleaning because the cleaning gun operator is able to access those “hard to reach” areas .

Also, because of its high pressure cleaning water. The user can keep a safe distance from the surface being washed and concrete removal . This visual standard has been prepared by the use of ultra high pressure hydro blasting machine. The standard however is applicable to surfaces produced by a whole range of hydro jetting pressures.

Repairing a large concrete with jackhammers is simply ineffective and causes lots damage to the remaining structure. Requiring extra work to repair and can not guarantee the integrity of the structure,especially for the bridge .

Watex hydro demolition machine robot can do the work of up to 35 jackhammer operators, can increase productivity and improve safety. Noise is greatly reduced, and silica dust exposure .

Hydrodemolition does not produce vibrations along the reinforcing steel and therefore.This will increase the life expectancy of the refurbishment, up to 50% better bonding on rough surfaces and cost less in the future for construction.

Protection before hydrodemolition

Ear protection with ear plugs are highly recommended before high pressure cleaning. Body protection with gloves, overalls, leather coat, or canvas blast suit is necessary.

If your requirement is high pressure, high water volume and high flow rate output. Then your answer is in heavy duty high pressure cleaner.We also called it is high pressure water blasting machine

High pressure cleaning is a technique for cleaning surfaces. Which relies entirely on the energy of water striking a surface to achieve its cleaning effect.

Abrasives or sand are not need in hydroblasting systems. Consequently the problems caused by dust pollution and by the disposal of spent abrasives are eliminated.

Two different high pressure jetting operating pressures are commonly encountered.

  • High pressure water blasting, operating at pressures above 1000 bar
  • Ultra high pressure hydro jetting , operating at pressures above 2000 bar

It also provide the equipment used is capable of cleaning to the visual standard depicted.
The steel surfaces produced by high pressure cleaning do not look the same as those produced by dry abrasive blasting, or slurry blasting.

This is because water on its own cannot cut, or deform steel like abrasives. High pressure washing surfaces therefore tend to look dull, even before they “flash rust”. With active corrosion pitting, shows a mottled appearance after hydroblasting.
