If concrete is not kept moving until it reaches its destination, then it can end up solidifying. Using a concrete pump makes this process much easier since the pump guides the concrete to its destination with little to no issues. However, concrete pumping can suffer a number blockages. This is often caused by rocks in the concrete, leaks around the pipeline or even concrete that is unable to move smoothly. Suffering a blockage while pumping concrete can set back your construction project for a few hours. Therefore, it is important to unblock the pump as soon as possible. Locating a block can be difficult since the blockage can occur at a number of different points in the pipeline. Fortunately, there are a few tips that you can use to help clear this block as soon as possible

Tap a Hammer Against Your Pipes

If your pipeline is not too long, then you can quickly pinpoint the block through sound. Tapping your hammer against your pipes and pumps will produce two different sounds. Tapping on a pipe that is filled with concrete sounds much different than tapping on a pipe filled with air. In areas that contain concrete, you should hear a muffled and dull sound. While in the areas that lack concrete, you will notice a high-pitched ringing sound. The difference in sounds will give you a good idea of where the concrete stopped flowing, and this can help you to identify the cause of the blockage.

Check the Joints on Your Pipes for Leaks

If the joints on your pipes are damaged, then they will cause the cement grout to leak. This leak can impact the way that the concrete flows through your pipes. Since grout is usually used in order to make sure that the cement flows seamlessly from one area to another, a lack of grout will cause the cement to build up and come to a standstill. Once the cement and grout blockage have been removed from a leaking joint, then the joint should be fixed or sealed. Sealing or fixing the joint immediately will help to ensure that the cement moves freely in this area.

When your concrete pipes and pumps are working smoothly, then the construction process can finish quickly. However, one tiny blockage can derail the process. Therefore, use these tips to ensure that you are able to quickly locate any blockage when pumping concrete.
