Rubble Facing Stone – Blue Sandstone

This characteristically Welsh blue sandstone is sourced from a local quarry in South Wales. The colouring is a true blue-grey, made even more striking by occasional bronze seams. We leave it ‘undressed’ for a raw, naturalistic finish ideal for both traditional and contemporary designs.


This blue sandstone is transported from the quarry in South Wales back to our yard in Pontrilas, Herefordshire, where our in-house skilled stonemasons crop it to create Rubble facing stone.

Rubble stone is highly variable in the size, shape and bed width of the pieces. This makes it perfect for emulating a historic stone wall, and also gives it a raw, contemporary feel for more modern architecture. Due to this variable characteristic we would recommend that you employ a professional stonemason with experience of working with rubble stone.

If you need a quicker and easier building stone, our Blue Sandstone cladding slips would be a good alternative. It’s the same stone but hand-dressed to give it a softer, riven surface, and then sawn to a slim cladding slip of 15-25mm thickness. Our natural stone cladding slips are faster and simpler to use than Random or Rubble facing stone, and can be applied by a competent general builder.

We’ve provided a few tips on how to build a stone wall, and if you need any advice, give us a call.

What is Rubble building stone?

Rubble building stone is an identical material to our random building stone, but is ‘undressed’. This means it has a more raw, naturalistic type of finish, whereas random building stone has a more regular, coursed appearance.

Rubble building stone is also less uniform than random stone in its sizes. The heights and widths are more irregular, with the bed width cropping to between 75mm and 200mm (3 -8 inch) as standard. (‘Bed width’ is the width of your footing). As with all our building stone, our rubble stone will have at least one usable face per piece.

Being less regular in shape and size, rubble building stone requires the skills of a trained stone mason or appropriately experienced builder. The stone finish and technique is suitable for house construction and commercial / public buildings, restoration and renovation projects, particularly in historic settings and where a more traditional effect is desired.

One bulk bag of rubble building stone supplied to the standard 75mm-200mm (3 -8 inch) bed width will provide enough material for between 2.5 to 3.5 square metres of facing stone depending on the product.

Please note that the bulk bags are not weighed, but are approximately 900kgs

What if I need my stone cut differently?

Stone can be provided “as dug”. This is stone dug straight from the quarry, without cropping to a specific bed width, and is popular when building dry stone walls.

We can also provide corner stones as required. These are made by cropping the random building stone as normal, then turning each piece of stone at right angles and cropping once more to make a right angled corner.

Building and walling materials to match

Our Blue Sandstone cladding slips are an identical material to the Rubble facing stone, albeit in a slimmer format with a softer, riven surface. This is ideal where space is at a premium, and can be applied by a general builder (or even DIY).

We also supply Blue Sandstone as Random building stone (with a hand-dressed riven face) and Random Tumbled (for softer edges and surface).

We also source a range of flagstones, cobblestones, lintels and cills from responsible suppliers throughout the world, to provide our customers with a wider choice of colour, finish and prices.

Many of these can be closely matched to other stone products, or can be successfully combined with complementary ranges – for example, using lighter coloured stone for cills and coping stones. If you would like advice, examples or ideas about combining stone ranges, do give us a call – or even better, pop in to our showroom.

For natural landscaping we provide boulders and rockery stones from all of our own UK quarries. These are available in various sizes from small rockery stones to 12 tonne boulders.

An important note about natural stone

Whilst we have done our utmost to ensure the stone and colours displayed on our website are accurate, they are to be used as a guide only. Because stone is a natural product, texture and colour will vary from piece to piece. As we work through the quarry, seams will yield slightly different coloured and shaped stones.

The building technique, quantity, colour and type of mortar used will all impact on the the look of the finished product. Please bear this in mind when ordering stone products. For larger projects or any projects where a specific look is required, we recommend that test panels are built.
