On-Site Supervision & Water Preservation
At Crispy Pools (a dedicated division of Crispy Construction and Projects CC), we manage your complete renovation lifecycle—from initial drainage to final water re-commissioning. Backed by over 15 years of trade construction experience, every single project is personally managed and supervised on-site by Chris. Plus, we save your treated water on-site using our free commercial storage bladders.
Fixing Structural Shell Cracks with High-Tensile Steel Staples
Sandton’s deep granite substrate, rocky formations, and seasonal moisture variations exert heavy ground stress on buried pool structures. If a concrete pool shell fractures under ground movement, simply plastering over the gap will fail as the soil shifts again.
Exposing the Concrete Core
- We grind out the fracture line straight down to raw concrete.
- Our team removes all degraded material to reveal the full extent of the structural break.
- We establish structural shear points along the split before anchoring.
Cutting & Fitting Steel Stitches
- We cut deep horizontal channels perpendicular across the crack line.
- We hammer heavy-duty, high-tensile steel staples (stitches) directly into the concrete wall.
- The high-tensile steel bridge absorbs lateral ground pressure across the break line.
Structural Resin Anchor
- We anchor the steel staples using non-shrink structural epoxy resin.
- This mechanically binds both sides of the concrete shell back together as a unified solid structure.
- The rigid lock eliminates independent wall movement before we apply your choice of new interior finish.
Pool Resurfacing Options: Marble Plaster vs. Fibreglass
Classic Marble Plaster (Marblite) Resurfacing
- What We Apply: A traditional, hand-troweled 6mm layer of rock-hard, cement-bound crushed marble plaster.
- Best Suited For: Stable soil profiles, established residential properties, and homeowners who prefer an authentic, natural stone texture underfoot.
- How It Performs: Delivers a classic smooth finish, natural water reflection, and long-lasting mineral durability. We chip and key the old surface thoroughly to guarantee strong mechanical adhesion.
Flexible Fibreglass Relining
- What We Apply: Multi-layer composite glass matting (450gsm) saturated with chemical-resistant resin, sealed with a UV-stable gelcoat topcoat.
- Best Suited For: Active ground movement zones, expansive soil formations, aged concrete shells, and old pre-moulded fibreglass pools.
- How It Performs: Creates a continuous, watertight, flexible lining that accommodates subtle soil movement without cracking. The non-porous gelcoat resists algae growth and drastically simplifies routine maintenance.
Structural Alterations: Tanning Ledges, Steps & Floor Depths
If your pool’s physical shape or depth no longer aligns with how your family uses it, we alter the concrete shell layout while the pool is drained during renovation.
Building Tanning Ledges & Integrated Spas
- We cast custom concrete shallow tanning ledges (Baja shelves) inside the main pool area for relaxing or young children.
- We construct integrated spa seating areas outfitted with targeted hydrotherapy jets.
- We fit sunken hideaway roller channels to keep floating thermal covers neatly stowed below deck level.
Entry Options: Walk-In Steps & Stainless Steel Grab Rails
- We pour custom, non-slip concrete walk-in steps into the pool corner for effortless entry and exit.
- We replace or secure stainless steel handrails and grab ladders based on your access needs.
- We match step edges with non-slip coping stones or decorative waterline safety mosaic tiles.
Floor Depth Reductions & Reshaping
- Older pools with 2.2m to 2.8m deep ends consume excess water volume and require high heating energy.
- We backfill deep ends and cast a reinforced concrete floor to establish a uniform 1.4m to 1.6m swimming depth.
- We convert outdated curved pool outlines into modern, crisp geometric rectangles.
Free On-Site Water Storage Bladders During Renovations
Draining 40,000 to 90,000 liters of treated pool water into the street wastes mature pool chemicals and incurs high municipal tap refill costs.
Pumping Water into Private Storage Bladders
- Crispy Pools operates a private fleet of commercial-grade, heavy-duty water storage bladders.
- We deploy these polymer bladders to your lawn or driveway and store your treated pool water safely on-site at zero extra charge while interior shell work is underway.
Re-Commissioning Your Original Water
- Once your new marble plaster or fibreglass lining has cured, we pump your stored water straight back into the pool.
- This eliminates water bill spikes and saves you money on expensive chemical startup treatments.
Fixing Water Circulation & Relocating Return Jets
Older pools frequently develop stagnant dead zones because the original skimmer weir and return aimflow jets were positioned on the same wall right next to each other.
Core-Drilling Concrete Walls
- While the pool is empty, we use diamond core-drills to cut precise penetrations through concrete walls.
- We run heavy-duty PVC pipework underground and reposition return lines to stagnant wall zones opposite the skimmer weir.
Circular Vortex Flow
- Positioning return aimflows opposite the skimmer creates a continuous circular water current.
- The sweeping circulation pushes floating leaves and debris directly into the skimmer basket, maximizing filtration efficiency and distributing sanitizer evenly.
Modern Equipment Upgrades & Smart Automation
A complete pool renovation is the ideal time to replace old, power-hungry filtration equipment with energy-efficient hardware.
Inverter Heat Pumps & Solar Heating Panels
- We install high-efficiency inverter heat pumps that heat your pool quietly while throttling power consumption based on target water temperature.
- We integrate solar heating panel arrays to extend your swimming season using solar energy.
Energy-Saving Variable Speed Pumps
- We replace traditional single-speed pump motors with modern variable-speed eco pumps (e.g., Speck / Quality).
- Running the pump on low speed for daily filtration cuts electrical consumption by up to 70% while running near-silently.
Automated Salt Chlorinators & Digital Timers
- We install salt chlorination systems that generate sanitizing chlorine automatically from natural salt, eliminating manual chlorine dosing.
- We fit digital timer controllers equipped with surge relays to manage filtration cycles and underwater LED lighting straight from your smartphone.
Perimeter Upgrades: Coping Stones & Waterline Mosaics
Completing a pool renovation involves replacing weathered perimeter coping stones and renewing stained waterline tiles.
Non-Slip Bullnose Coping Stones
- We strip away old coping bricks and compromised bedding mortar around the perimeter.
- Our team lays modern, non-slip natural stone or quartz bullnose copings along the pool rim.
- We align the new coping edge flush with your surrounding patio, paving, or decking.
Glass & Ceramic Waterline Mosaic Tiling
- We hand-lay fresh glass or ceramic mosaic tiles along the waterline perimeter.
- The glazed surface prevents stubborn waterline scum lines and mineral scale from bonding to the wall plaster.
- The mosaic band provides a clean visual border against your new interior surface finish.
Tailoring Renovation Methods to Sandton Suburb Soil Dynamics
Sandton’s soil dynamics vary from rocky granite ridges to expansive clay zones in low-lying suburban valleys, requiring tailored installation techniques.

Verified Project Case Study: Fibreglass Relining in Dainfern Golf Estate, Sandton
The Initial Challenge
A luxury residential pool in Dainfern Golf Estate developed fine structural surface cracks on an old concrete shell, causing continuous water level drop and unsightly surface staining.
What We Did
- Deployed our mobile water storage bladders on-site to preserve 70,000 liters of existing pool water.
- Machine-ground the interior shell to sound concrete, ground out stress fractures, and anchored them with structural epoxy resin.
- Applied a seamless 450gsm fibreglass lining saturated with chemical-resistant resin and sealed with a UV-stable gelcoat topcoat.
- Installed fresh glass mosaic tiles along the waterline and step edgings.
- Recommissioned the preserved original water back into the newly restored pool shell.
The Final Result
The water loss was completely stopped, the pool interior was upgraded to a sleek, modern finish, and the project was completed under Chris’s daily personal supervision within 5 working days.
