Why should I use decking and paver supports? Supports can save you the laborious job of levelling a surface through digging out a surface levels, laying cement or installing lumber support posts. They simply sit on the underlying hard surface and a small adjustment brings the support to the required support height. If you need to create a floating surface that cannot penetration any underlying membranes, such as on a flat roof area; the risers come with protective rubber mats to sit on, where there is minimal risk of scratching a waterproof layer. Supports improve drainage by lifting sub structures and preventing localised pooling, as well as improving ventilation under the sub structure. This also helps to reduce the build-up of mould under the flooring surface. When used with paving they remove the need to deal with sand levelling and concrete fixing, allowing a much quicker installation. Compared to traditional post supports, the support pedestals are far lighter making them easier and safer to work with, especially in high locations.Customized Adjustable Pedestal For Decking website:http://www.globalmoonbay.com/adjustable-pedestal-for-decking/
