The outdoor living craze has been gathering pace over the past few years, and it can be attributed to homeowners' continually changing tastes and preferences. Therefore, one good strategy for concrete contractors to win over more clients is to build outdoor floors that last a long time. It is especially the case for properties with a flat backyard or front yard. One way to achieve a long-lasting, paved outdoor space is by using the proper concrete pumping techniques and avoiding common mistakes in the process. This article highlights tips for correct concrete pumping that rookies will find useful.
Keep the Hose Straight
Concrete pumps are equipped with different hose sizes that must meet industry standards considering the type of material that runs through the pump. While some hoses are wide and cannot twist easily, others can twist depending on the operator's movement. Notably, an operator has to move about the site directing the hose to where concrete is needed. If by any chance the operator is handling a concrete hose with a relatively narrow diameter, it is easy for the hose to twist along the length. Consequently, the kinks or twists lead to concrete blockage and affect the smooth flow of concrete. Moreover, when there is a blockage on the concrete pump hose, the pre-mixed concrete will begin to dry. Therefore, concrete pump operators must ensure the tube remains straight throughout the pumping process.
Know Location of Blockage
There are many reasons a concrete pump can be blocked by dry concrete, and mishandling the hose is one of them. While you might know what to do in case of a blockage, knowing the exact location of the block is a different issue. Most rookie pavers struggle with this and end up wasting valuable time. The first area you should look at when you detect blockage is the reducer, which is the section that joins the hose to the pump. If the blockage is around the pump area, you will see quick pressure build-up on the pump's indicators. On the other hand, if the pressure build-up is slow, then the blockage is most likely near the delivery end. Most importantly, quick identification of blockages in the concrete pump's system will save you valuable time.
Indicate Exclusion Zone
As mentioned earlier, hose blockages are frequent during concrete pumping. Notably, the faster the blockage is cleared, the better for the entire concrete laying project. Therefore, ensure that you secure an exclusion zone and label it accordingly before you begin pumping concrete to the site. When you are ready to clear the hose, direct its delivery end toward the exclusion zone and let everything from the blockage dump flow out. Since the blockage comes out under very high pressure, you should restrict access to the exclusion zone for safety reasons.
