Fiberglass pools are known for being low maintenance — but they’re not maintenance-free. After 10–15 years, many begin to show signs of wear like osmosis blisters, surface damage, and leaks.
Our Recent Resurfacing Work in Rondebosch
Recently, the team at GIBBS POOLS completed a full fiberglass pool resurface in Rondebosch where the pool was losing water daily and covered in dozens of blisters across the walls and floor. The surface had deteriorated to the point where popped blisters left rough craters, allowing dirt and algae to build up.








We carried out a full restoration by safely draining the pool, grinding out all damaged areas, allowing the shell to dry properly, and rebuilding the surface using a high-quality fiberglass lining system. The final result was a smooth, watertight, and visually like-new pool with a significantly extended lifespan. This project clearly shows that proper resurfacing — not painting — is the only long-term solution for fiberglass pools with osmosis and leaks.
At GIBBS POOLS, we proudly service Rondebosch, Newlands, Claremont, and surrounding areas with professional fiberglass pool resurfacing and leak repair.
The Problem: A Leaking Fiberglass Pool in Rondebosch
When the client contacted us, their pool had multiple issues:
- Constant water loss – needing top-ups 2–3 times per week
- Visible bubbling and blisters – across the entire surface
- Rough, stained finish – caused by burst blisters
This is a classic case of fiberglass osmosis, where water penetrates the gelcoat and reacts beneath the surface, creating fluid-filled bubbles that eventually lead to structural damage and leaks.
Why Fiberglass Pools in Rondebosch Develop Leaks
Pools in Rondebosch often experience these problems due to:
- Aging gelcoat – worn down by UV exposure and chemicals
- High groundwater levels – adding pressure to the pool shell
- Installation defects – weak laminate or trapped air
Painting over these issues only hides the problem temporarily — it does not stop it.
Our Fiberglass Pool Resurfacing Process
1. Safe Draining & Preparation
The pool is drained carefully to avoid structural damage caused by groundwater pressure.
2. Grinding Out All Blisters
Every blister is opened and ground back to solid fiberglass. Severe cases can involve 100+ damaged spots.
3. Drying the Pool Shell
The shell is allowed to fully dry, removing trapped moisture and preventing future blistering.
4. Structural Repair & Surface Preparation
Damaged areas are repaired, reinforced, and smoothed to create a uniform base.
5. Barrier Coat & Full Resurfacing
A protective barrier coat is applied, followed by full re-fiberglassing to create a new waterproof surface.
6. Refill & Chemical Start-Up
The pool is filled in one go and balanced immediately to ensure proper curing.
Signs Your Pool Needs Resurfacing
