Structural issues in pools are physical failures of the pool shell or surrounding structure, such as cracks, settlement, tile or coping movement, and plaster delamination. When you see these signs in your pool you need a proper diagnosis and a repair plan tailored to the cause and your goals. We inspect the shell, deck and equipment to recommend whether resurfacing, targeted repairs, or a full renovation is the right path.
What we mean by structural issues
Structural issues are problems that affect the pool's load bearing or water containment function. They differ from routine surface wear or cosmetic concerns because they can let water escape, undermine surrounding decks, or signal failing support below the shell.
Common structural problems we evaluate
- Visible cracks in the plaster or concrete shell, ranging from hairline to wide separations.
- Settling or heaving of the pool floor or walls, often visible as uneven tile lines or steps.
- Separation between coping and shell, or loose coping stones and coping grout failures.
- Persistent leaks that do not track to plumbing or equipment, suggesting shell penetration or voids.
- Delaminated plaster or finish peeling away from the substrate.
- Tile or bond beam failures where the tile line moves or gaps open.
Why structural issues matter in Lewisville and the Dallas Fort Worth area
Local soil types, seasonal ground movement and irrigation practices in Lewisville and the broader Dallas Fort Worth area influence how pools age. Soil expansion and contraction can create stresses on concrete shells and coping. Left unaddressed, structural problems can grow, leading to larger repairs and higher expense.
We factor local conditions into every inspection and recommendation. That means looking for signs of differential settlement near retaining walls and landscape beds, and checking how pool equipment and water chemistry may have contributed to finish failures.
Key concepts every homeowner should know
How failures start
- Movement in the underlying soil transfers stress to the shell and coping.
- Hydrostatic pressure from high groundwater can lift or crack an empty shell if relief is inadequate.
- Corrosion of embedded steel or failures in initial construction details can cause localized collapse or cracking.
What we look for during an inspection
- Crack type and pattern. Linear hairline cracks suggest shrinkage, while stepped or widening cracks point to movement or structural load.
- Leak localization. Is water loss isolated to one area, or widespread? Persistent loss after equipment checks suggests shell problems.
- Finish condition. Delamination or bubbling can indicate poor adhesion, chemical attack, or substrate movement.
- Adjacent structures. Patio, retaining walls and plantings can affect pool performance.
How we decide between repair options
When we assess structural issues we balance the cause, extent of damage and the desired outcome. Our approach is practical and focused on durable results that fit the site and your lifestyle.
Inspection checklist we follow
- Visual mapping of cracks and finish defects.
- Leak test with equipment and chemical checks to rule out plumbing.
- Evaluate coping, bond beam and tile condition.
- Assess surrounding grade and deck for settlement or erosion.
- Recommend further testing when needed, such as core samples or hydrostatic testing.
After the inspection we outline options. For limited shell cracks and intact structure a targeted repair plus refinishing may be sufficient. For recurring leaks, widespread delamination, or severe settlement we often recommend a more extensive renovation. We always explain the tradeoffs between a focused repair and full resurfacing or remodeling.
Repair and restoration approaches we use
We do not provide do it yourself instructions for structural repairs. These interventions require trained crews and, in many cases, specialized equipment. Below are the repair approaches you will see discussed during planning.
- Patching and epoxy injection. For narrow structural cracks with stable surrounding shell, structural epoxy can restore continuity.
- Localized structural rebuilding. When a small section of the bond beam or wall has failed, we remove the damaged area and rebuild with appropriate materials and reinforcement.
- Resurfacing and finish replacement. After structural repairs, a new plaster or aggregate finish restores the water barrier and appearance. See our page on Pool Resurfacing for finish options and processes.
- Full renovation. For aged shells with multiple failure modes we may recommend a full renovation that addresses shell stability, coping, tile, decking and equipment integration. Read about our Pool Renovation services.
- Concrete pool resurfacing. For gunite and concrete pools with extensive surface and structural defects, a concrete resurfacing scope can include substrate repairs plus a new durable finish. See Concrete Pool Resurfacing.
When a structural issue is likely a cosmetic problem and when it is not
Not every plaster crack is structural, and not every discoloration is a leak. We use a combination of tests and visual clues to separate cosmetic wear from true structural failure.
- Cosmetic signs: surface crazing, light staining, or thin hairline shrinkage cracks that do not leak and do not penetrate the shell.
- Structural signs: cracks that widen over time, movement in tile or coping, persistent unexplained water loss, and visible gaps where the shell meets the deck.
We recommend an inspection when you notice repeated water loss, changes to steps or tile alignment, or when cracks appear near the bond beam or coping.
Related services and coordination
Structural repairs often touch multiple trades and services. We coordinate the full scope so you have a single point of responsibility for the pool work.
- Pool plastering and finish replacement after structural stabilization. Learn more about Pool Plastering.
- Pool remodeling when the structural work is part of a larger design update. See our Pool Remodeling page for design examples.
- Permits and site planning. Structural interventions may require permits and coordination with local building officials. For planning advice see Permits And Codes and Renovation Planning.
How to evaluate contractor recommendations
When you get multiple opinions, compare them by scope, underlying diagnosis and long term durability. A high quality recommendation will document the cause, list alternative repairs, and explain why one option is preferred.
- Ask for a clear description of the root cause. Is the crack due to shrinkage, settlement, or corrosion?
- Look for a phased plan that separates temporary patch work from permanent fixes.
- Check how the proposal addresses adjacent elements, including coping, deck and equipment.
Pro tip: A good report includes photos and a sketch of the affected areas. That makes it easier to track whether a repair is holding over time.

Frequently asked questions
How can I tell if a crack is structural or superficial?
Structural cracks often change over time, appear in the shell rather than just the finish, and may be associated with water loss or tile movement. Superficial shrinkage cracks are usually hairline, do not leak, and stay stable. An on site inspection helps determine the type and cause.
Is a persistent leak always a structural problem?
Not always. Persistent leaks can come from plumbing fittings, returns or equipment. If equipment and plumbing checks do not locate the leak, the shell and underdeck should be inspected for penetrations or voids.
Will resurfacing fix structural cracks?
Resurfacing alone addresses the finish and water barrier, not the underlying structural cause. If cracks are structural we repair the substrate first, then resurface. Resurfacing without substrate repair risks recurring failures.
How long does a structural repair or renovation take?
Timelines vary with scope. Small repairs and follow up resurfacing can take a few weeks. Larger structural repairs, drainage work or a full renovation take longer. We outline timelines as part of the project plan.
Key takeaway
Structural issues are about safety and durability, not just looks. Early diagnosis prevents larger costs and gives you more repair options. We evaluate cause, recommend the right scope, and coordinate repairs and resurfacing to restore a safe, usable pool.
Frequently asked questions
What causes pool shell settlement?
Settlement is usually caused by changes in the supporting soils, including erosion, poorly compacted fill, or tree roots. Identifying the source shapes the repair method.
Can hydrostatic pressure damage a pool?
Yes. High groundwater can exert upward pressure on an empty or breached shell. Adequate hydrostatic relief and proper drainage reduce the risk.
When should I consider a full renovation instead of spot repairs?
Consider full renovation when you have multiple failure modes, recurring leaks, widespread delamination, or when you want to update finishes and equipment at the same time.
