Constantia Fibreglass Pool Lining & Mosaic Specialists

Is your Constantia pool cracked, leaking, stained or just looking tired? A professional fibreglass pool lining is the most reliable way to bring it back to life. At Aquatic Pools, we’ve spent nine years relining, resurfacing and rebuilding swimming pools across Constantia and the wider Southern Suburbs of Cape Town — turning rough, porous, leaking interiors into smooth, sealed, crystal-clear pools that last for years.

Whether you’re restoring an old marbelite pool, finishing a new build, or finally fixing a leak that won’t go away, our fibreglass lining gives your Constantia pool a seamless, one-piece shell that adds 15+ years of life.

Why fibreglass is the best pool lining for Constantia

Constantia’s large garden properties and mature trees mean leaf load and shifting ground — a seamless, non-porous fibreglass lining keeps maintenance low and water where it belongs. On top of that, fibreglass:

• Stops leaks for good — one continuous, non-porous shell with no joints or grout lines for water to escape.
• Resists cracking — it flexes with minor ground movement instead of cracking like rigid surfaces.
• Stays cleaner — algae and stains can’t sink into the non-porous surface, so you use fewer chemicals.
• Keeps its colour — a quality gelcoat finish holds its colour for years instead of chalking.
• Is fast to install — most relines are done in a matter of days.
• Lasts 15+ years when correctly applied.

Our fibreglass pool lining services in Constantia

We handle every type of fibreglass work, from a full reline to a single repair:

• Full pool fibreglass relining — a complete new fibreglass shell over your existing pool interior.
• Concrete-to-fibreglass conversion — upgrade a tired concrete or marbelite pool to a modern, low-maintenance finish.
• Crack & hollow-spot sealing — we grind out, fill and reinforce cracks and drummy areas before lining.
• Gelcoat colour finish — a smooth, hard-wearing colour coat in your choice of finish.
• Spot fibreglass repairs — targeted fixes for leaks, cracks or damage when a full reline isn’t needed yet.

Prefer a different finish? We also offer custom mosaic design and marbelite resurfacing for Constantia pools.

Signs your Constantia pool needs relining

• The water level keeps dropping (a classic sign of a leak)
• Rough, chalky or sandy surfaces underfoot
• Cracks in the shell or around steps and lights
• Stubborn black algae staining that won’t brush out
• Exposed aggregate or worn-through patches
• A faded, blotchy interior no amount of cleaning fixes

Fibreglass vs marbelite: which is right for your pool?

Both are good options — the right one depends on your pool and budget:

• Fibreglass is non-porous, crack-resistant and easiest to keep clean, typically lasting 15+ years. It’s the best long-term choice for leak-prone pools.
• Marbelite gives a classic, stone-look finish at a lower upfront cost but is porous and generally lasts 7–10 years.

As specialists in both, we’ll give you honest advice for your specific Constantia pool — not a one-size-fits-all pitch.

Our fibreglass relining process

1. Free on-site inspection & quote at your Constantia home.
2. Drain & surface preparation — grind back the old surface and repair every crack and hollow spot.
3. Fibreglass application — matting and resin form a strong, seamless, waterproof shell.
4. Gelcoat colour finish — a smooth, UV-stable colour coat.
5. Cure, refill & balance — we refill and balance the water so it’s swim-ready.

Most residential relines take a few days to a week, depending on pool size and condition.
