Signs Your Pool Needs Relining

Over time, all swimming pools begin to show signs of wear. While some issues are cosmetic, others indicate that your pool lining or surface is starting to fail. Identifying these signs early can prevent more costly structural damage and help you plan a timely renovation – especially in climates like Gauteng, where temperature shifts and sun exposure accelerate wear.

Look out for:

1. Rough or Worn Pool Surface

If your pool surface feels rough underfoot or has lost its smooth finish, it’s a clear sign the existing layer is deteriorating.

This is especially common with older marbelite finishes, which naturally wear down over time.

2. Cracks or Visible Damage

Hairline cracks can develop into larger structural issues if left untreated.

While not all cracks mean a full rebuild is needed, they often indicate that the pool surface has reached the end of its lifespan.

3. Persistent Staining or Discolouration

Stains that no longer respond to cleaning or chemical balancing may be embedded in the surface itself.

This is often a sign that the protective layer has broken down, allowing minerals and algae to penetrate deeper.

4. Water Loss or Suspected Leaks

If your pool is losing water faster than normal evaporation, the lining or surface could be compromised.

Relining helps restore the waterproof barrier and prevent ongoing water loss.

5. Flaking, Peeling or Chalking

When the surface starts to flake, peel or produce a powdery residue (chalking), it indicates that the material is breaking down and no longer performing effectively.

6. The Pool Is 10–15+ Years Old

Even without obvious damage, most pool finishes have a lifespan.

If your pool is over a decade old and hasn’t been resurfaced, it’s worth assessing its condition.

Repair vs Relining — What’s the Difference?

Minor issues can sometimes be repaired, but widespread wear or multiple problem areas usually point towards a full relining or resurfacing.

If you’re unsure, a proper assessment can help determine the most practical and cost-effective approach.

When to Consider Pool Renovation

Relining is often part of a broader pool renovation, which may include:

  • New finishes or tiling

  • Structural repairs

  • Updated plumbing or filtration

  • Design upgrades
