On-Site Fiberglass vs. Marbelite Pools: A Cost & Comparison Guide for Gauteng Homeowners
Choosing the right finish for your swimming pool is a pivotal decision, impacting not just its appearance but also its long-term durability, maintenance, and overall investment. In Gauteng, for both new pool constructions and extensive renovations, two primary on-site applied finishes stand out: Fiberglass lining and Marbelite. Both offer unique advantages, but understanding their distinct characteristics, maintenance demands, and especially their respective costs, is crucial for making the best decision for your property.
​
At Morrisens Projects, we specialize in applying both advanced fiberglass linings and traditional Marbelite finishes to pools across Gauteng, offering expert advice and professional installation or renovation services. Let's delve into these two popular pool surfacing options to help you make an informed choice
Understanding On-Site Applied Fiberglass Pool Linings in Gauteng
On-site applied fiberglass refers to the process of applying layers of woven glass fibres saturated with specialized resins directly onto a prepared pool shell (often an existing concrete or Marbelite pool, or a custom-built concrete structure). This creates a seamless, durable, and fully bonded fiberglass lining that cures in place.
Key Advantages:
​
-
Exceptional Durability & Flexibility: The cured fiberglass lining forms a highly resilient and flexible barrier. This flexibility is a significant advantage in Gauteng, as it allows the lining to withstand minor ground movement without cracking, effectively bridging existing hairline cracks in the underlying concrete.
-
Seamless & Non-Porous Surface: The smooth, continuous gelcoat finish is non-porous, making it highly resistant to algae growth, staining, and chemical absorption. This translates to significantly lower chemical usage and easier cleaning compared to porous plaster finishes.
-
Enhanced Lifespan: A professionally applied fiberglass lining, especially with a high-quality gelcoat, can last for 15-25 years or even longer before needing refurbishment, offering excellent longevity.
-
Comfortable & Aesthetic: The smooth, non-abrasive surface is comfortable on feet and swimwear, available in a wide range of vibrant colours.
-
Excellent Renovation Solution: It's an ideal choice for renovating aging concrete or Marbelite pools, transforming their appearance and resolving issues like leaks and rough surfaces.
​
Key Disadvantages:
​
-
Skilled Application Required: Proper installation is crucial and demands highly skilled and experienced applicators to ensure a flawless, long-lasting bond and finish.
-
Weather Dependent: The application process can be sensitive to adverse weather conditions (rain, extreme cold/heat), which can sometimes extend project timelines.
-
Preparation Intensive: For renovations, extensive preparation of the existing shell (chipping, cleaning, crack repair) is required before application, adding to the initial effort.
Understanding Marbelite Pools in Gauteng
Marbelite is a traditional plaster finish applied to a concrete pool shell. It's a mixture of white cement, marble dust, and sometimes pigments, creating a classic, durable surface.
Key Advantages:
​
-
Unlimited Customization: Because Marbelite is applied to a custom-built concrete shell, you have complete freedom in pool shape, size, and depth, allowing for truly unique designs.
-
Classic Aesthetic: Offers a timeless, natural, and often vibrant look, with a range of colour options from traditional white to blues and greens.
-
Structural Strength: When applied to a well-built concrete shell, Marbelite pools are incredibly robust.
-
Non-Slip Texture: The slightly coarser finish provides a natural grip.
Key Disadvantages:
​
-
Longer Installation Time: Building a concrete pool and applying Marbelite is a multi-step process that can take weeks, including crucial curing time.
-
Higher Maintenance: Marbelite is porous, making it more susceptible to algae growth and staining, which requires more frequent brushing and higher chemical usage to maintain water quality.
-
Chemical Sensitivity: Improper chemical balance can lead to etching, discolouration, and surface degradation.
-
Surface Wear: Over time (typically 8-15 years), Marbelite can become rough and require re-marbeliting. Cracks can also develop due to ground movement or structural issues.
-
Higher Long-Term Cost: Due to more frequent maintenance and the need for re-marbeliting every 8-15 years, the long-term cost can be higher.
On-Site Fiberglass vs. Marbelite: A Head-to-Head Comparison for Gauteng Pools
1. Surface:
-
On-Site Applied Fiberglass Lining: Smooth, non-porous, and highly algae-resistant gelcoat finish.
-
Marbelite Pools: Porous, slightly textured plaster finish.
2. Durability:
-
On-Site Applied Fiberglass Lining: Flexible and excellent at bridging or preventing cracks in the underlying substrate due to minor ground movement.
-
Marbelite Pools: Rigid; susceptible to cracks in the plaster or underlying concrete, especially with ground movement.
3. Maintenance:​
-
On-Site Applied Fiberglass Lining: Low maintenance; requires less brushing, fewer chemicals, and offers superior resistance to algae growth.
-
Marbelite Pools: Higher maintenance; requires more frequent brushing, more chemicals, and is more prone to algae and staining.
4. Lifespan (Finish):
-
On-Site Applied Fiberglass Lining: 15-25+ years for the gelcoat before major refurbishment is typically needed.
-
Marbelite Pools: 8-15 years for the plaster before re-marbeliting is usually required.
5. Installation Time (for Renovation/Lining vs. New Concrete Build):
-
On-Site Applied Fiberglass Lining: Faster for renovation/lining an existing pool than a full new concrete pool construction.
-
Marbelite Pools: Longer, especially for new builds (involves multi-stage concrete construction plus plaster curing).
6. Customization:
-
On-Site Applied Fiberglass Lining: Excellent; conforms seamlessly to the shape of an existing concrete pool, offering extensive design flexibility for renovations.
-
Marbelite Pools: Unlimited for new custom-built pool shapes and sizes. For renovations, it conforms to the existing pool shape when re-plastered.
7. Feel:
-
On-Site Applied Fiberglass Lining: Smooth, comfortable, and less abrasive on skin and swimwear.
-
Marbelite Pools: Slightly coarser, providing a traditional texture with natural grip.
Cost Comparison in Gauteng (Estimated)
Understanding the financial investment is critical. Here's a general estimated cost comparison for both new installations and renovations in Gauteng for Fiberglass and Marbelite pools. Please note: These are estimates and the final cost will depend on your specific pool size, current condition, chosen features, site accessibility, and the complexity of the project. A detailed on-site assessment is always required for an accurate quotation.
​
-
On-Site Fiberglass Lining (Renovation/Relining) in Gauteng:
-
For existing concrete or Marbelite pools requiring a durable, seamless fiberglass lining, you can expect an estimated investment ranging from R 15,000.00 to R 70,000.00+ (VAT Incl.). The lower end may cover smaller pools or simpler resurfacing, while the higher end accommodates larger pools or those requiring more extensive preparation and additional features.
-
Marbelite Pool Renovation/Replastering in Gauteng:
-
For existing concrete pools needing re-marbeliting (replastering), the estimated cost can range from R 20,000.00 to R 45,000.00+ (VAT Incl.). This typically involves draining, preparing the old plaster, and applying a new Marbelite finish.
-
New Pool Installation Costs (Brief Overview for Comparison):
-
New Custom Concrete Pool with Marbelite Finish: Custom-built concrete pools are significant construction projects. Costs for a fully installed basic pool can start from R 100,000 to R 400,000+ in Gauteng, scaling up significantly with custom shapes, deeper sections, and elaborate features.
-
New Custom Pool with On-Site Fiberglass (less common for full new build): While possible for very unique shapes, most new fiberglass pools are pre-moulded. If a concrete shell is built and then fiberglass lined, the cost would be comparable to a new concrete/Marbelite build, plus the fiberglass lining cost.
Which Pool Finish is Right for Your Gauteng Home?
The best choice for your pool depends on your priorities:
​
-
Choose On-Site Fiberglass Lining if: You want to renovate an existing pool with a highly durable, low-maintenance, chemical-efficient, and smooth surface that can bridge existing cracks in the underlying concrete. It offers a premium, long-lasting finish.
-
Choose Marbelite if: You are building a brand-new, uniquely shaped pool (where concrete construction is essential) and prefer a traditional, textured finish, and are prepared for more frequent maintenance and potential future replastering.
