KennStone Walling
Products / KennStone
KennStone Walling is the latest addition to the extensive range offered by Stowell Concrete. Named after our first concrete production facility in North Somerset, KennStone is a reconstituted walling block range developed to replicate natural stone. It combines aesthetic appeal with functional design, suitable for both charming and contemporary properties.
KennStone Walling is available in two distinct finishes: tumbled and split, and comes in multiple different sizes across three course heights: 65mm, 140mm, and 215mm. The manufacturing process is designed so that the product lengths suit the builders' requirements and reduce cutting onsite.
At Stowell Concrete, we prioritise flexibility and service in the supply of our KennStone Walling. We offer four premier colour blends; Tetbury Gold, Woodstock Cream, Dunster Red and Milverton Blend. These blended colours compliment our standard colours; Ashcott Grey, Cranmore Buff and Hewish Grey.
With other colour variations, and colour blends currently in development, we can work closely with architects, developers, and housebuilders in the design and specification of KennStone properties.

BESPOKE COLOUR OFFERING
At Stowell Concrete we have invested in the latest batching technology, enabling us to blend up to four different colours simultaneously. This flexibility in production allows us to create bespoke mixes that can accurately match the stone of the surrounding area onsite. Ideal for meeting local planning regulations, a bespoke colour blend can meet the aesthetics of the surrounding area whilst replicating natural stone.
While we supply exclusively through builders merchants, we are happy to collaborate directly with housebuilders, specifiers and architects to ensure the product matches all requirements.
Before manufacturing the whole order quantity, we will manufacture a sample pallet for approval. Once approved the lead time to manufacture and supply a bespoke colour is 6 to 8 weeks.
