Swimming Pool Waterproofing in Sunshine Coast | Pool Membrane & Leak Protection
Sunshine Coast Waterproofing provides swimming pool waterproofing for new pools, renovations, repairs and remedial projects across Sunshine Coast, QLD. Our service is designed to protect concrete pool shells, walls, floors, joints, penetrations and surrounding wet areas from water loss and moisture movement through the structure.
Swimming pools remain under continuous water pressure, which places ongoing stress on the shell, joints, pipe penetrations, corners and surface finishes. Cracks, porous concrete, failed membranes and poorly detailed fittings can allow water to escape from the pool or enter surrounding building materials. Correct waterproofing requires the substrate to be stable, properly prepared and compatible with the selected membrane and finishing system.
We assess the pool shell, visible defects, construction joints, penetrations and planned surface finish before preparing the area and applying the waterproofing system. The work is coordinated with crack repairs, rendering, tiling, coping and other pool construction stages so the membrane remains continuous and is allowed to cure before the pool is filled.

Why Choose Us for Swimming Pool Waterproofing in Sunshine Coast
Detailed Pool Shell Assessment
Effective pool waterproofing begins with assessing the concrete shell, surface finish, cracks, joints and areas around penetrations. We inspect for visible defects, moisture pathways, hollow sections and previous coating failures before recommending the repair scope. This helps determine whether the pool requires localised treatment, broader membrane work or additional structural repairs before waterproofing begins.
Continuous Membrane Coverage
The waterproofing system must remain connected across pool floors, walls, corners, steps, benches and service penetrations. We reinforce vulnerable junctions and detail the membrane around pipes, lights, skimmers and other fittings to reduce weak points through the pool shell. Each coat is applied in line with the requirements of the selected system and allowed to cure before finishing work proceeds.
Coordinated Pool Construction
Pool waterproofing must be completed at the correct stage of a new build or renovation. We coordinate the work around shell preparation, crack repairs, rendering, tiling, coping and equipment installation so the membrane is not damaged or covered prematurely. Clear sequencing helps create a suitable waterproofed base for the final pool surface.
Swimming Pool Waterproofing Projects We Handle Across Sunshine Coast
New Swimming Pool Waterproofing
New swimming pools require waterproofing across the concrete shell before tiles, renders or other finishes are installed. We prepare the floors, walls, steps, benches, corners, construction joints and service penetrations before applying a continuous membrane system. The waterproofing is coordinated with rendering, tiling and equipment installation so the membrane remains protected and cures correctly.
Pool Renovation Waterproofing
Pool renovations may expose cracked render, deteriorated coatings, failed membranes or incomplete waterproofing beneath the existing finish. We assess and prepare the exposed shell before installing a replacement membrane suited to the updated pool surface. New steps, benches, lights and fittings are carefully detailed to maintain continuous waterproof protection.
Pool Leak Repairs and Remediation
A leaking pool may lose water through cracks, construction joints, penetrations, fittings or failed waterproofing beneath the surface finish. We identify the likely source, remove affected materials and repair the exposed concrete before applying a replacement membrane. Localised treatment or full pool remediation may be required depending on the extent of the damage.
Swimming Pool Waterproofing Services for Sunshine Coast Properties
Concrete Pool Shell Waterproofing
Concrete pool shells require continuous waterproofing across walls, floors and changes in direction before the final surface is installed. We prepare the shell, treat visible defects and apply the selected membrane to create a protective barrier beneath tiles, renders or other compatible finishes.
• Pool floors and walls
• Internal corners and transitions
• Steps, ledges and benches
• New and existing concrete shells
• Preparation before surface finishing
Pool Crack Waterproofing
Cracks in a pool shell may allow water to pass through the structure or place stress on the surrounding finish. We assess the crack type and complete suitable repair or reinforcement before applying the surrounding waterproof membrane.
• Hairline and visible cracks
• Wall and floor cracks
• Crack reinforcement systems
• Repairs beneath tiled surfaces
• Integration with broader membranes
Construction Joint Sealing
Construction and movement joints can become pathways for water under constant pool pressure. We prepare and seal these areas using suitable waterproofing materials that connect with the adjoining membrane and surface system.
• Wall-to-floor joints
• Poured concrete junctions
• Pool extension joints
• Changes in shell construction
• Reinforced membrane detailing
Pool Penetration Waterproofing
Lights, pipes, skimmers, returns and other fittings create openings through the pool shell that require careful membrane detailing. We seal around these penetrations so the waterproofing remains connected to the surrounding surface.
• Pool light fittings
• Skimmer boxes
• Return and suction lines
• Pipe penetrations
• Membrane collars and sealants
Spa and Plunge Pool Waterproofing
Spa pools and plunge pools contain tight corners, benches, jets and multiple penetrations that require precise waterproofing. We apply the membrane across the complete internal shell and detail the system around fittings and changes in direction.
• Spa pool shells
• Plunge pools
• Bench and seat areas
• Jet and pipe penetrations
• Waterproofing before tiling
Pool Membrane Replacement
A failed pool membrane generally requires the covering tiles, render or coating to be removed before a replacement system can be installed. We prepare the exposed shell, repair defects and apply a new membrane before the pool is resurfaced.
• Failed coating removal stages
• Shell cleaning and preparation
• Crack and joint treatment
• Replacement membrane application
• Preparation for pool resurfacing
Swimming Pool Waterproofing FAQs for Sunshine Coast Property Owners
Swimming pool waterproofing costs depend on the pool size, shell condition, access, number of cracks and penetrations, surface preparation and selected membrane system. A new pool with a stable concrete shell may require less remedial work than an existing pool with failed coatings, damaged render or widespread cracking. An inspection helps determine the appropriate waterproofing scope.
A concrete swimming pool generally requires a waterproofing system because concrete can be porous and may develop cracks or weak points under water pressure. The membrane helps reduce water movement through the shell and provides a suitable base for compatible tiles, renders or coatings. The required system depends on the pool construction and final finish.
A leaking pool caused by a failed membrane usually cannot be properly repaired without removing the tiles or surface finish covering the affected area. Surface sealants may address small visible gaps, but they do not replace damaged waterproofing beneath the finish. The source and extent of the leak should be assessed before selecting a repair method.
Pool waterproofing must cure for the period specified by the membrane manufacturer before tiles, renders or water are introduced. The required time varies according to the product, number of coats, substrate condition, temperature and humidity. Filling the pool too early may damage the membrane or affect its bond to the surrounding system.
Signs of failed pool waterproofing include unexplained water loss, damp areas around the pool shell, cracking, hollow tiles, staining, efflorescence and moisture appearing in adjoining structures. Persistent water level changes may also be caused by plumbing leaks, so the pool should be assessed before waterproofing repairs are planned.
