On average, the cost of concrete pool installation can be as low as $35,000 and as high as $ 100,000; liaise within will depend on your budget and what you are comfortable with.

The best solution is usually to fill in the crack with hydraulic cement or have the area resurfaced. Minor cracks can cause algae problems or calcium nodules, but they won't cause a leak.

Concrete crack leak sealing involves injecting a fully flexible water reactive hydrophilic polyurethane under high pressure. High-pressure injection of high-quality TDI liquid polyurethane forces the material into leaking cracks, joints, voids and other defects.

Most leaks in pools occur through cracks in floors or walls, but some develop through highly porous or honeycombed concrete. When pools are at least partly below the groundwater table it is possible for leakage to occur in either direction.
