New untreated Oak (natural colour) Sleepers
Although accurately machined and an attractive golden brown when first produced they quite rapidly turn a light grey and are prone to warping and splitting. Unlike reclaimed 'Rustic' Oak types new Oak sleepers are likely to move after installation. This is partly because they are usually made from 'Green Oak' which may not be properly seasoned. They are not as durable as the new Tanalised Pine unless properly treated prior to placement and we categorically recommend new oak should always be treated if in contact with the ground. A non-permeable ground sheet is recommended between the sleeper and soil.
