3 Most effective Methods to Concrete Demolition

 Concrete removal and careful grout application are very cost-effective ways to limit the likelihood of cracking. If you are comparing it to pouring new concrete to repair foundations. Certain Materials are removed/destroyed by any method of concrete removal or demolition. These materials comprise non-structural items like paint, bricks, plastics, etc. The methods used to remove concrete are as follows.

  • Crushing

Crushing this is the first-line way to concrete demolition from its place and surface. It removes all the small stones and other particles that cannot be easily removed with a hammer. Such as sand particles that are larger than 10 microns in size. 

Concrete Demolition carries out the crushing process more effectively. The procedure involves crushing them using a hammer (or blow hammer), at the surface of the concrete. And then apply pressure on it for approximately 15 seconds. Once a concrete slab has been completely obliterated, a water jet is applied on top of it. It is to blow away the loose particles. And other small pieces that can’t be blown off, and more water jets are added. 

This makes sure the concrete is broken down into fine particles and cracks free. To get concrete out of its original shape, an abrasive bit is used. Then it is pushed into a large container, such as this one called ball-and-crusher. 

The process involved in crushing 

During the process, some concrete sticks to the ground around the edges and gets stuck around them. As the cement hardens under pressure. It gives a solid base for all the dirt and silt particles to settle down. A variety of sizes and weights of sand are used during the process. such as 12mm to 200mm, depending upon the depth of the concrete slab, layer depth, etc. To avoid the sand sticking out or escaping from the bricklayer after crushing it. There is a special type of equipment called a “ball and crane” which is used to crush the block.

Crushing should start immediately after removing a concrete slab as it may have dried out. It takes about three hours for the concrete to become dry. but only two hours for the concrete to become wet again which takes up considerable time and effort.

Why is crushing useful?

Crushing is quite useful for people who have already started dumping their concrete at the edge of their property. It is not for those who would like to install temporary walls around their building. Therefore, you need to get a specialist concrete demolisher. Some concrete buildings require concrete floors for them to provide protection. For example, if your house is built directly above a river. you cannot use the floor as the concrete slab can destroy it and ruin it.

  • Picking Up Cinder Blocks

Picking up cinder blocks can be done by passing hot water through a hole in the bottom of the block. Also submerging the cinders in the water and using a hammer. The whole operation can take only 20 minutes, but it requires lots of caution and care. It is due to the weight of cement in the cinder blocks. It tends to increase after you fill it with water. so the load on the hammer should be carefully managed. Another method is to take around 1kg of cinders as the amount depends upon the thickness. 

They are best to extract concrete right from the soil. The soil absorbs water more quickly than a cinder block. This helps the cement to set faster and form stronger concrete to achieve a longer lifespan. After pouring the concrete into the holes or Tibbles, cover these Tibbles. Cover it with grass to help it dry out. Also, it is better to avoid adding too much water to the concrete while picking the Tibbles. 

  • Sandblasting

Sandblasting is one of the most effective ways to remove concrete from its place and surface. Sandblasting is done by blowing air or a spray gun on certain places on the concrete surface. such as the edges and joints of concrete, to create tiny fractures on the concrete surfaces. And then saturate with cold water.

Sandblasting needs almost full power. so don’t go far into your home or office building without having the correct tools and supplies. Otherwise, the water won’t reach the exposed concrete surface. When you’re setting up the work, make sure the tarp is stable enough to support the ceiling. It is where the work will be situated.

When using sandblasting, remember that there is a huge difference between spraying air rather than water. Water contains chemicals (such as calcium chloride) that can damage or destroy the concrete. On the other hand, sandblasting uses very little, if any, water. 

Therefore, it reduces the chance of damage, especially in areas where no existing waterproof concrete has existed in the past. There’s no worry about damaging anything as the water is being sprayed directly on the surface. Therefore, sandblasting works wonders in removing and destroying concrete. And making it safe and sound to walk underneath the rubble.
