Shot blasting, Sandblasting Concrete
Concrete is a building material made from a mixture of small stones, grit, sand, cement, and water, which can be spread or poured into moulds and forms a stone-like mass on hardening.
A method for producing Portland cement was patented by Joseph Aspdin in 1824. Reinforced concrete was invented in 1849 by Joseph Monier. In 1889 the first concrete reinforced bridge was built, and the first concrete dams were built in 1936.
There are numerous positive aspects of concrete:
- It is a relatively cheap material and has a relatively long life with few maintenance requirements.
- It is strong in compression.
- Before it hardens it is a very pliable substance that can easily be shaped.
- It is non-combustible
- It can be strengthened with other products such as steel rods
As our shot blasting techniques are so versatile we can treat walls, ceilings, underpasses, pools and tanks to name but a few.
We can prepare the surface on newly cast concrete or refurbishment of existing concrete.
This is in many cases in the form or metal beams and can be found on or within things such as bridges, buildings, retaining walls and commercial buildings for example.
When old or existing structures are refurbished or updated they are often required to be taken back to the main structural /building fabric.
Shot blasting, Sandblasting can remove old coatings and apply a key on the surface ready for new coating application.
As we at A4W Ltd, have a wide range of shot blasting and sandblasting machines that are all mobile we can undertake works in all areas from the top of the tallest buildings, under bridges, over water or on site at installation.
Shot blasting, sandblasting uses media that is fired at speed to directly abrade or peen the surface.
With our wide range of machines and media we can get the exact spec to meet the requirements of your project.
We can also offer access, encapsulation and containment solutions.
