Can marblelite become porous and leak?
Yes. marblelite can wear down, crack, become porous or develop openings over time. Once the surface reaches the end of its service life, water may move through multiple small defects rather than one obvious hole. In those cases, patching one spot may not solve the overall water loss.
How do I know if marblelite is finished?
Signs include rough texture, exposed aggregate, hollow or weak areas, stains, cracks, flaking, visible openings and recurring water loss through the shell. If dye is drawn through several surface defects, a full resurfacing recommendation may be more practical than repeated patch repairs.
Should I choose fibreglass lining or Re-marblelite?
The better option depends on the pool structure, existing surface, leak pattern, budget and expected lifespan. Re-marblelite restores a traditional plaster finish, while fibreglass lining can provide a continuous waterproof lining when installed correctly. If the existing marblelite is porous and leaking in many places, fibreglass may be recommended as a stronger waterproofing solution.
How can I tell the difference between evaporation and a leak?
Evaporation normally changes with weather conditions and affects most exposed pools in a similar way. A leak is more consistent and may continue even during cooler weather. Warning signs include water dropping to a certain level and then stopping, air entering the pump, wet paving, soft soil, recurring algae from dilution, or a water bill that increases without another explanation. Professional testing is the reliable way to separate evaporation from a true leak.
What is dye testing?
Dye testing uses coloured dye near suspected leak points such as lights, weirs, aimflow jets, cracks, steps, mosaics and surface defects. If the dye is pulled into an opening, it indicates active water movement through that point. Dye testing is useful for visible or accessible leaks, but it must be done carefully with the water calm and circulation off.
Can pool leaks be repaired permanently?
Many leaks can be repaired long term if the correct cause is identified and the repair method matches the defect. However, old surfaces, unstable ground, poor previous work or multiple hidden leaks can complicate guarantees. A proper diagnosis gives the best chance of repairing the correct problem first.
