The Brew Cabin

I am about to lay a path/patio in my back garden and am having trouble finding slabs I like. I really like the style&stone rockstone silver/grey pavers, but need 450x450x50 slabs. These are only available in 200x200x50 max.

The path will form a step edge so the slab sides need to look good too.

Does anyone know of similar products in larger sizes?
I have a charcon sample on order (moorgate grey) but haven't found any other.

Rockstone in Silver Grey is available as a 300x200x60 unit, for the UK market. There are larger sizes available on the continong, but they are only available on special order in the UK (ie, 180m² or more). This is because, in the UK, they are marketed as block pavers rather than flags/slabs and the generally accepted opinion is that owt smaller than 300x300 is a block, and owt bigger is a flag. :)

There are no readily available "similar products" on the British market. Marshalls have their Stein & Design imports from Germany, but these are really aimed at commercial works rather than patios, which is reflected in the cost. No British manufacturer has a washed aggregate block paver, currently.

There are other textured pavers, such as bush-hammered or shot-blasted, but these textures should not be compared directly with a washed aggregate, as they still rely on the artificial dyes in the concrete matrix for their colouring, unlike the Washed Aggs. which derive the vast majority, if not all, of their colouring from the aggregate which is exposed by the washing process.

The Charcon Moordale is, if I recall correctly, a shot-blasted product, and so the surface exposes both the concrete matrix and a small proportion of natural aggregate. As far as I know, the texturing is only carried out to the top face, so the sides/edges of the flags would not be similarly textured, which may not be what you're looking for.
