The installation of concrete calls for more than pouring. Concrete pumping is a delicate area in construction, and the entire process needs to be done correctly the first time to ensure desirable results.
When the process is done right, you are assured of great reliable support that will last you longer. However, most people make errors by using inadequate concrete pumping techniques in the construction. Below are concrete pumping errors that you can avoid by bringing a qualified contractor on board.
Using the Wrong Cement-to-Water Ratio
If you want to maintain the integrity of a concrete slab, ensure that the cement-to-water ratio is correct. You'll only achieve an ideal mixture if the ratio is well calculated to balance the weight of water and cement. An excess of water weakens the concrete, while less water makes the concrete difficult to pour and spread. A competent concrete contractor knows the required standard ratio, but this may differ depending on the project's unique circumstances.
Blocking the Concrete Pump
A lot of things can go wrong when the concrete pump is blocked. Usually, the blockage can result from many bends in the pipeline, extraordinarily wide or sharp turns, and failure to maintain the pipeline or even clean them when done with a concreting project. It can also arise from a high water-to-cement ratio. Again, when it takes you longer than usual to carry out the process, concrete loses its pumpability, leading to blockage. The best way to avoid the frustrations and delays caused by a blockage is by hiring a skilled contractor.
Failing to Site Plan Appropriately
Professional concrete contractors advocate for adequate site planning. Failure to plan the site is a recipe for failure. For instance, you must be very keen when compacting the sub-foundation to achieve regular and robust service lines. Additionally, you will have fewer weak points when you use the ideal gravel consistency.
Lessening the Curing Time
The duration taken for concrete to cure varies. While on average it can go for twenty-four to forty-eight hours, some projects take an entire week. When you fail to allow the concrete to cure properly, the contrite becomes brittle and won't last long. Curing is also necessary where you want to add color to the concrete.
Selecting Wrong Concrete Additives
You should select your admixtures such as filling and pumping agents keenly. When you make a wrong choice on the admixtures, you are likely to cause blockage during the pumping process.
Concrete pumping is a costly affair, and no property owner would want to have the process done all over again. That is why you need to hire an experienced concrete contractor to avoid the above mistakes and ensure a lasting outcome.
