One of the most striking features in landscaping design incorporates the use of standing stones or “megaliths”.
Steeped in mystery for thousands of years, these “standing stones” invoke feelings of awe and wonder as to their original purpose. Why are they here? Who moved them to their final positions? How were they moved, as many stones are estimated to weigh hundreds of tons?
Obviously the stones we can provide are not such heavy weights, but they can provide a focal point in any landscaping project.
Not an undertaking to be taken lightly, with forethought and planning, this is not beyond the abilities of any DIY enthusiast. Variations on a theme involve setting out the “standing stones” in either groups clustered around a central stone or as stone circles. The only limitations are the ones imposed by the builder
Please get in touch if you require specialist standing stones or ideas .

Gwrhyd Blue Pennant Sandstone from Rhiwfawr Quarry in the Upper Swansea Valley is one of the strongest available in the UK. The quarry is roughly 12 miles north of Swansea and not far from the small hamlet of Rhiwfawr and the outskirts Neath.
Its technical properties are far superior to other sources of pennant and allow it to be either used in thinner thicknesses compared to other stones or to carry higher loads. For instance a 400x900mm flag stone at 50mm in Gwrhyd Pennant will carry a class 5 loading as shown in the table below where normal pennant will only carry class 2.
| Class | Min Breaking Load kN | Typical Use |
| 0 | 0 | Decoration |
| 1 | 0.75 | Slabs bedded on mortar, pedestrian only. |
| 2 | 3.5 | Pedestrian and cycle areas. Garden Balconies. |
| 3 | 6 | Occasional car, light vehicle and motorcycle access. Garage entrances |
| 4 | 9 | Walking areas, market places occasionally used by delivery vehicles. |
| 5 | 14 | Pedestrian areas often used by heavy vehicles. |
| 6 | 25 | Roads and streets, petrol stations. |
All Gwrhyd blue pennant stone is tested to British Standards. This includes durability tests such as freeze thaw and flexural tests after freeze action. Beyond this our products are also tested for other durability indicators not covered in the British Standards such as polished paver test vales. This gives security that the product will be sound during service.
What you will see an abundance of marks made by animals that burrowed into the wet sand when it was the bed of a shallow sea or river. You can also clearly see the ripple marks caused by the action of the water. There are superb examples of this in the Gwrhyd Pennant Quarry sandstone paving at the entrance of National Waterfront Museum in Swansea.
Flagstone when used on floors, patios, walkways and foyers always looks exceptional. Blue Pennant patterned stone has a formal, yet rustic appearance, which is great for creating that special touch.
Gwrhyd Pennant fine grained riven sandstone varies from light blue/grey through to brown/rust colors. Gwrhyd Pennant stone is quarried from the Rhondda Beds of the Pennant series of Carboniferous Sandstones.
Riven paving has a naturally rough surface because it is hand split, or ‘riven’, from large flagstone paving slabs. The blocks are formed in sedimentary layers called strata or beds which allows the stone to be split with hand tools.
