Lafarge's concrete tech 'first'
First publishedon www.AggBusiness.com
France-based Lafarge has developed a new type of concrete which reduces the need for water drainage infrastructure.
Hydromedia is permeable and can drain water at a rate of 3cm per second, which reduces the risk of flooding. With a porousness of up to 35%, it can be used for patios as well as for pavements or car park surfaces and other public spaces.
