Seacork is a material for heavy-duty light-weight use, particularly in marine environments. It is composed of 90% – 95% natural cork, with 5% – 10% polyurethane. A little cork powder is also added to the mixture.

The PU is fitted with a milky saturation that completely closes any micro-pores, making the material completely waterproof. This also stops dirt from getting into the cork, meaning that it is much longer lasting too.

It is produced under compression, using the PU as a glue to bond the material. Besides making the cork material sea-water resistant, it also makes it much stronger. Uses are mainly decking for boats, as it is cheaper and lighter than teak, as well as anti-slip, resilient and impact resistant.

Due to the low-maintenance coating, it can be easily cleaned using a sponge and water. Over time, the material develops a whitish UV patina. This can be left alone as it protects the cork from the elements.

Further advantages of cork include a wide operational range of temperature (-180°C to +120°C). The material by Seacork contains no more than 10% polyurethane, so its mostly cork content classes it as renewable. The material is available in a range of sizes, and is generally easy to install.
