Does anyone know where I can get paving-circle spares? The pieces I’m after are about 400mm long, 300mm wide at one end and about 250mm wide at the other end so slightly wedge shaped. If you laid the long sides together they would eventually form a circle..There were 33 of them around a pear-shaped pond that I had to change the liner on and unfortunately 10 of them broke whilst separating them from the mortar.

Sorry can’t help with suppliers but casting concrete is quite easy so you can make them if needs be.

Thanks Brick but not really wanting to cast 10 slabs..

Try local garden centre – they sell those sorts of things.

Sounds like it could be one of Marshals many pre cast concrete products, try their website.
