The cost of wet pour rubber can seem expensive but over the lifetime of product , it is relatively economical solution.
An average cost per square metre is £30-40 per square metre excluding base works. This can increase with different graphics and colour combinations. Many suppliers have a minimum install amount.
You should expect the surface to last up to ten years. The rubber will naturally shrink over its lifetime particularly if edged with timber. This can be repaired with a band repair.
