Water leakage can originate from an assortment of external or internal sources.  It can seep in through compromised sealing in block work, retaining walls, movement cracks and construction and expansion joints, etc.  The leaks are usually evidenced by elevated levels of moisture, efflorescence and variable or active leaking water.  Polyurethane injections offer a multitude of advantages in addressing water leaks, including:

• Product flexibility;
• Guaranteed strong adhesion;
• Application not dependent on weather conditions;
• It forms a new permanent watertight seal;
• Cost- effectiveness;
• Reduction in operational downtime;
• May be used for leak-sealing applications in concrete, masonry and natural stone structures; and
• May be used during the initial construction or later in time so as to extend the service life of the structure.
