Polyurethane Leakage Injection

Polyurethane Leakage Injection

For most buildings, leakage starts any time after construction. The problems associated with leakage typically appear within the first five years. Water leakage, if not treated properly, is one of the main contributing factors to building damage, primarily reinforcement corrosion. Water leakage may result in the consequential reduction in the usable area within the structure in addition to reduced functionality and use. Water intrusion can drastically increase the physical damage to a structure and internal finishing that can lead to costly remediation and repairs.

The aforementioned problems as well as measures that can be implemented to limit the effects of water leakage on residential, commercial, and high-rise buildings are accordingly investigated by the team of experts at Venus Star and thereafter the future benefit solutions are suggested to our clients.

In some situations, it is necessary to apply leak treatment methods to stop water intrusion, including superior repair processes where chemical resins (polyurethane) that interact with water are used because these materials tend to be rigid, fill the voids and act as an offset. To aid in controlling leakage into a concrete component, it is important to understand the best water control solution that can efficiently stop the water leakages from the structure. The most appropriate and effective method of treatment standard is the resin injection which is the best method for the treatment of Leakage cracks of buildings, bridges, dams, and other types of concrete structures.

Properties of polyurethane:

Polyurethane is a fluid resin which is injected into concrete cracks, expansion joints and other voids in concrete structures. When used in concrete crack injection applications the polyurethane is injected into a crack; within minutes the polyurethane undergoes a chemical transformation from a liquid to a solid.

The versatility, and consequently the popularity, of polyurethane resins in crack injection applications stems from polyurethane’s properties:

• ► 1. It has a very short cure time, making it ideal for active leak sealing.
• ► 2. Extremely low viscosity allowing for even the finest cracks (cracks with a width less than 0.2mm) to be sealed.
• ► 3. The resin cures normally whether a foundation crack is wet, actively leaking, or damp.
• ► 4. Polyurethane, once cured, can be quite flexible, allowing for movement in the structure and keeps leaks to remain sealed.
• ► 5. Polyurethane crack injection is used in Civil Construction and maintenance of Civil Assets due to its flexibility in application and its reliability in repairing cracks and damage in concrete structures. Polyurethane crack injection is the most efficient and cost-effective method in repairing leaking cracks in major concrete assets.
