The DiamonDeck Pond Safety Grid Is Designed To Last For In Excess Of 25 Years.

The DiamonDeck safety cover is installed into ponds, above or just below the water surface, to make sure that anybody falling into the pond, are held above the dangerous depths.

The cover is installed with the intention that it is left as its fitted and not adjusted or removed, other than for pond maintenance, which mostly can be achieved without the need to remove it, and some sections can be unclipped by an adult too for easier access. Added to this, we do suggest regularly checking the cover as a ‘sensible, responsible and good practice’ just to make sure there are no visible signs of any adjustment to the safety cover, tampering etc.
