Water blasting concrete we always use ultra high pressure water jetting cement with 1,800bar operating pressure can meet you requirement to remove the cement .
Buildings that are exposed to much wear and/or environmental pollution, underground garages, bridges, sport stadiums and dams are concerned.
If concrete starts to crumble, the basic structure of the building can be endangered in consequence of that.
Renovation becomes absolutely necessary in order to save the building. High pressure water blasting concrete. You must remove the crumbly construction material from the sound one.
For that purpose water jetting is the ideal method. it is also possible to remove concrete with a drill hammer, but this method has big disadvantages. the use of a drill hammer causes vibrations in the building.
Reinforcements of water blasting concrete
After being exposed by a drill hammer, must be sandblasted in order to remove rust from the rebar. Complicated as well as intensive work process is not necessary.
Because concrete removal and rust removal can be done in one step without any other means. last but not least drill hammers cause much more noise and disturb often inhabitants and neighbors.
Primary aim of any water blasting concrete is to remove the damaged areas. Without damaging the surrounding material or steel reinforcements.
In contrast to a pneumatic hammer, whose force application goes deep into the joint and is transferred far into the building.
Water blasting solutions are very local and targeted on the position to be treated. This means that hardly any structure-borne sound is transferred to the construction and the formation of stress cracks is avoided.
High-pressure water jetting can be used for a wide range of concrete applications.
At high pressure with a lower flow, water can actually remove coatings without damaging the sound concrete below. Add an abrasive to the jet and water can completely cut through a concrete slab with rebar inside.
Advantages of water blasting cement
- Works quickly
- Does not damage sound concrete
- Low dust levels
- Can be automated
Reinforced concrete is a particular problem as the steel reinforcement corrodes with time.
Water blasting concrete can be seen from cracks or spalling of the cement, renovation is unavoidable for conserving the static load capability of the structure.
water blasting concrete ,we always use ultra high pressure water jetting cement with 1,800bar . Operating pressure can meet you requirement to remove the concrete . Cause here is the carbonation of the concrete, a chemical reaction in which the effect of water and air lowers the pH of the concrete to 10 or less.
This loss of the protecting alkali surrounding makes reinforcement corrosion possible, causing serious damage to the reinforced concrete.
In this, the steel reinforcement in the area affected is exposed so that targeted restoration of the corrosion protection can be made.
