Resin and Crack Injection Service
Echo Square are industry leading experts in Resin and Crack Injections. This type of service is required when a concrete structure develops cracks over time. With a Resin injection we can effectively seal the crack in the concrete structure which stops the structure from leaking.
How Resin Injections Remedy Cracks
Resin Injections involve injecting a liquid epoxy resin into cracks, voids, or cavities in concrete to restore its integrity and prevent further damage. The resin hardens and bonds with the surrounding concrete, creating a strong and durable repair.
Although a concrete structure is strong and durable, cracks can easily show and water can escape through the cracks. Not good if this is a water tank! However a resin injection is perfect to seal the cracks and stop water leaking through.
Before starting the injection, a thorough assessment of the concrete structure is conducted to identify the extent and nature of the damage. Furthermore this helps determine the appropriate injection technique and materials to be used.
The surface of the concrete is prepared by cleaning it thoroughly and removing any loose debris or contaminants. This is typically done by using a wire brush, compressed air, or other suitable methods.
Injection ports installation
Small holes or ports are drilled into the concrete along the crack or affected area. These ports serve as access points for the resin injection and are spaced at regular intervals to ensure proper distribution of the epoxy.
Then expoxy is injected into the prepared ports using specialized injection equipment, such as injection guns or pumps. As a result the resin flows through the cracks, filling voids and saturating the surrounding concrete.
In some cases, pressure is applied during the injection process to ensure that the epoxy reaches all the voids and effectively fills the cracks. The pressure also helps to compact the epoxy and enhance its bond with the concrete.
Curing and hardening
After the resin injection is complete, the epoxy needs time to cure and harden. This process usually takes several hours or days, depending on the specific epoxy product and environmental conditions. Once fully cured, the epoxy forms a strong, durable bond with the concrete, restoring its structural integrity.
