UC4 Gravel Boards
Are the gravel boards you are buying described as pressure-treated for longevity? This does not mean it is suitable for posts and ground contact. We stock gravel boards that are treated to Class UC4 meaning they are suitable for close ground contact and come with a 30 year desired service life!
UC4 Gravel Boards in Kent
We treat Kiln Dried Radiata Pine on a specific cycle with a higher-than-average chemical concentration to offer a 30-year desired service life BS8417 part 4. This requires full sapwood penetration, not just 6mm penetration as required by incised spruce. Fixings and splitting in the timber may be greater than 6mm.
We normally hold in treated UC4 Radiata Pine for a 30-year desired service life the following gravel board sizes:
22 x 150 | 30 x 150 | 45 x 145
