How to Fix Pool Cracks Before Damage Spreads

Pools may look solid and seamless, but beneath the surface, they are constantly under stress—from water pressure, temperature shifts, and ground movement. One of the most common and costly issues in pool structures is cracking. Left untreated, these cracks can lead to severe water damage, weakened concrete, and expensive repairs.

Why Do Cracks Form in Pools?

Cracks can develop at any stage—during construction or years after usage. The main causes include:

Uneven settlement of soil beneath the pool
Poor reinforcement during construction
Hydrostatic pressure from inside or outside
Thermal expansion and contraction of concrete
Improper sealing of joints and structural connections

Example of pool concrete crack repair and injection process

What may appear as small surface cracks can easily deepen, allowing water to infiltrate and damage the structure over time. Learn more about potential leak points in Drainage Gaps in Pools.

Why Surface Repairs Aren’t Enough

Cracks in pools require more than a surface-level patch. Water can penetrate through the smallest gaps, often hidden from view. To truly prevent damage, the solution must penetrate deep into the concrete and bond from the inside out—especially in wet and high-pressure conditions.

Logic UW: Deep Crack Injection with Pico Technology

Logic UW is an advanced injection solution specifically designed for sealing surface and deep concrete cracks. Its unique formula allows it to:

Detect and seal even hairline cracks
Penetrate deeply using Pico Technology
Bond to wet surfaces and seal under pressure
Prevent unwanted water accumulation and leakage
Protect against long-term structural degradation

Logic UW is applied by drilling holes at 25 cm intervals, then precisely injecting the material into the crack path. This ensures complete filling of gaps—even those not visible to the eye.

Where Can It Be Used?

Thanks to its strong flexibility and adhesion, Logic UW is suitable for:

Pool floors and walls
Ceilings and structural joints
Stairs and column bases
Repairing pressure-induced cracks

Eco-Friendly and Guaranteed to Last

Logic UW is formulated with bio-based components, making it safe for the environment while delivering industrial-grade performance. It comes with a 20-year product guarantee, offering peace of mind for both homeowners and professionals.

Conclusion: Small Cracks Can Lead to Big Problems

Even the tiniest untreated crack can lead to major water leakage, structural issues, and maintenance costs. Logic UW provides a reliable, long-term solution by sealing cracks from within, protecting your pool before the damage escalates.
