Form and pump repair is a method of repairing concrete structures, particularly those with post-tensioned cables. It is a process that involves the injection of a specially-formulated concrete mixture into cracks or voids in the structure using a pressure pumping system.

The first step in the form and pump repair process involves the creation of a form or a temporary casing around the damaged area. The form helps to contain the concrete mixture and ensures that it is distributed evenly throughout the damaged area.

Next, the concrete mixture is prepared and placed into a pressure pump. The mixture is then injected into the damaged area through small openings in the form, filling any cracks or voids. The pressure pump is used to control the flow of the mixture, ensuring that it is evenly distributed throughout the damaged area.

The form and pump repair method is effective for repairing concrete structures that are under tension, such as post-tensioned concrete bridges, buildings, and parking structures. It is a fast, efficient, and cost-effective method of repairing concrete structures that provides long-lasting results.

The form and pump repair method is often used in conjunction with other repair techniques, such as surface repair or surface sealing, to ensure a complete and thorough repair.

Air Pockets

In the form and pump repair method, it is important to ensure that no air pockets are trapped inside the injected repair material. Trapped air pockets can weaken the repair, causing it to fail over time, and potentially leading to further damage to the structure.

To avoid this, Texas Strengthening Technologies uses specialized air vent tubes, which are strategically placed into the existing concrete. These tubes allow any air to escape during the injection process, ensuring that the repair material fills the damaged area completely and without any voids.

This step is crucial in ensuring the longevity of the repair. By removing air pockets, the repair material can bond effectively with the existing concrete, creating a strong and stable repair that will last for many years.

The form and pump repair method is a reliable and effective solution for repairing concrete structures, particularly post-tensioned concrete structures. With its focus on quality and safety, and the use of specialized techniques and equipment, Texas Strengthening Technologies is well equipped to carry out this type of repair work, ensuring that your structure is safe and secure for years to come.
