Flexstone Stone Overflow Grille
This Flexstone stone overflow grille has transverse slats – the look of a classic grille, but in stone. The element is 50 × 24.5 cm, 4 cm thick, and weighs 9 kg.
In the manufacturer's photos, Flexstone also follows curved walls, so it is used for freeform pools as well.

Advantages of the stone grille
- Reconstituted stone with a non-slip surface instead of plastic – the grille blends in with the coping and paving.
- Material certified to UNI EN 13451.
- The same colours as Carobbio coping stones and paving.
- Athermic – does not heat up in strong sun.
- Versions for the manufacturer's different overflow copings; the joints are adjusted to the coping.
- Made in Italy by a company with 50 years of experience.
How the grille is installed
- Choose the version according to the overflow coping: V1 – for Spiaggia coping, V2 with two chamfers – for Standard and Alto coping, V4 – for Medio coping.
- Before installation, treat the grilles inside and out with Primer epoxy resin – the manufacturer requires this.
- The grille rests loosely on the edge of the overflow coping and on the support on the paving side, so that it can be lifted when the channel is cleaned.
- Corner grilles are fitted at the corners, and radius grilles along curved walls.
- Leave about 1 mm between the elements; their dimensions have a tolerance of ± 5 mm.
Materials for laying and cleaning
- Primer – two-component epoxy resin: 2 l for about 24 m of overflow coping, 5 l for about 60 m.
- Alimepox – two-component epoxy resin with white pigment for the overflow channel: 2 l for about 14 m, 5 l for about 35 m.
- Deter-AC for cleaning after installation and Cibermac for seasonal cleaning – 5 l containers.
Maintenance
Lift the grilles and clean the channel under them regularly. Wash them with water and the manufacturer's cleaning products. Do not use a high-pressure washer on smooth surfaces, aggressive chemicals or de-icing salt.
Important before ordering
The products are a mix of natural aggregates and pigments, so the colour and sandblasting may differ between batches. For paving over 16 m², alternate elements from all the pallets. The tolerance for each size is ± 5 mm. Whitish patches (efflorescence) and, more rarely, brownish ones are possible – a natural phenomenon with cement-based materials that disappears over time. The manufacturer's warranty covers replacement of a defective element that has not yet been laid, so inspect the goods before installation.
