Decorative fountains
Decorative fountains require a continuous waterproofing build-up matched to recirculating water, chlorination or treatment chemicals, basin geometry and wet detailing. This engineering guide frames the application intent without replacing the current system specification or product technical data sheet.
Use and application
The application intent is waterproofing of decorative fountains. Start by qualifying the substrate, exposure, service level and maintenance constraints. Rayston Epoxy Plus, Polyurea Rayston A and Impertrans are typical reference products for this application. Compare the current Products and Systems documentation, and use the associated application context at Ponds artificial lakes to keep the scope distinct.
01
Recirculating water, basins and wet detailing
Fountain basins see continuous immersion, splash zones, chlorination or other treatment chemicals, and frequent wet–dry cycling at edges and overflows. Concrete or rendered basins bring porosity and cracking risk; finishes and decorative overlays must not break membrane continuity. Basin floors and walls, nozzles, pipe penetrations, overflows, weirs, lighting sleeves and perimeter upstands need a continuous, documented detail before the lining route is fixed.
02
Layers and references
Define the sequence from prepared substrate through primer or bond coat, functional membrane or body coat, reinforcement where specified, and protective or finish layer where required. Use the current technical data sheet for preparation, mixing, consumption, thickness, overcoat windows and cure; the Calculator supports quantities, while Systems and the product references establish the applicable route.
03
Common mistakes
- Ignoring chlorination or treatment chemistry when selecting lining and finish compatibility.
- Treating the basin floor as the whole waterproofing detail and omitting walls, overflows, nozzles, lighting sleeves or perimeter terminations.
- Closing the build-up before checking moisture, adhesion, thickness, pinholes and cure under immersion conditions.
04
Operating sequence
1. Record water chemistry, treatment regime, basin dimensions, substrate condition and service scenario. 2. Map overflows, nozzles, pipe penetrations, lighting sleeves, upstands and repair zones. 3. Select a compatible route in Systems and verify every layer against the current technical data sheet. 4. Calculate quantities with the Calculator. 5. Approve a representative area, document preparation and application controls, inspect continuity and release the fountain only when the project requirements are met.
