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
Randburg’s diverse topography—from clay pockets in Ferndale to steep rocky inclines around Northcliff—exerts continuous earth pressure on pool structures. If a concrete pool shell fractures under ground tension, 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
We offer both classic marble plastering (Marblite) and heavy-duty fibreglass relining, providing clear guidance based on your pool shell’s age, surrounding ground dynamics, and personal aesthetic preferences.
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, 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 Randburg Suburb Soil Dynamics
Randburg’s topography ranges from steep rocky ridges to clay-heavy valleys, creating varied ground pressures across properties. Matching your renovation finish to local conditions ensures permanent durability.
Ridge Formations & Steep Slopes (Northcliff, Cresta & Fairland)
- Suburbs: Northcliff, Cresta, Fairland, Robin Hills, Blackheath.
- Ground Dynamics: Rocky substrates and elevated inclines place differential earth movement stresses on lower pool walls.
- Renovation Approach: High-tensile steel stitching on stress fractures combined with a heavy-duty, flexible 450gsm fibreglass lining that seals against movement.
Expanding Clay Pockets (Ferndale, Blairgowrie & Randpark Ridge)
- Suburbs: Ferndale, Blairgowrie, Randpark Ridge, Darrenwood, Bordeaux.
- Ground Dynamics: Clay soils expand during wet summer months and shrink during winter, applying lateral force to concrete shells.
- Renovation Approach: Fitting hydrostatic relief valves during shell preparation alongside reinforced concrete floor bonding before applying Marblite or fibreglass finishes.
Established Residential Stands (Linden, Emmarentia & Greenside)
- Suburbs: Linden, Emmarentia, Greenside, Fontainebleau, Victory Park.
- Ground Dynamics: Mature gardens with large root systems and older pool shells requiring layout modernizations, floor depth reductions, and new coping stones.
- Renovation Approach: Complete shell relining, floor depth adjustments, walk-in step builds, and energy-efficient pump installations.
Verified Project Case Study: Relining & Leak Repair in Parkhurst / Linden Border
The Initial Challenge
An older residential concrete pool near the Linden border was losing 4,000 liters of water weekly through an undetected fracture line, with severely degraded interior plaster and obsolete filtration pipework.
What We Did
- Deployed our mobile water storage bladders on-site to preserve the 60,000 liters of existing pool water.
- Ground out the structural crack, installed high-tensile steel stitches, and sealed the wall split with non-shrink structural epoxy resin.
- Diamond core-drilled new return aimflows on the opposite wall to resolve circulation dead zones.
- Applied a heavy-duty 450gsm fibreglass lining with a UV-resistant gelcoat topcoat and installed a high-efficiency variable-speed pump.
- Recommissioned the preserved water back into the newly restored shell.
The Final Result
The underground leak was entirely resolved, power consumption was cut significantly, and the project was completed under Chris’s direct on-site management within 5 working days.

Frequently Asked Questions About Pool Renovations
How much does a pool renovation cost in Randburg?
Renovation cost depends on pool size, structural condition, and selected surface finishes. Minor surface overhauls cost less, while structural steel stitching, floor depth reductions, or full fibreglass relining require larger budgets. Contact Chris directly for a precise on-site assessment.
How long does a pool renovation take?
A standard resurfacing project takes between 3 to 5 working days. Complex structural renovations involving steel stitching, depth reductions, walk-in step construction, and new coping installations take between 7 to 10 working days.
Will cracks reappear after the renovation?
If a structural crack is simply plastered or painted over, it will reopen as the soil shifts. When we mechanically stitch the concrete core using high-tensile steel staples embedded in structural epoxy resin, the split shell is locked together permanently to prevent future movement along that break line.
Which finish is better for Randburg ground: Marble Plaster or Fibreglass?
Marble plaster (Marblite) is ideal for stable flat ground, offering a classic solid feel underfoot. Fibreglass relining works exceptionally well in ridge areas and clay soils (such as Northcliff, Ferndale, or Blairgowrie), as its flexible composite membrane seals against moisture and accommodates subtle ground shifts without cracking.
Do I lose my pool water during a renovation?
No. We deploy our mobile storage bladders to store your chemically mature water on-site completely free of charge. Once structural work and surface finishes cure, we pump your original water straight back into the shell.
