Ronacrete Eco Tree Pit system is available in a range of attractive natural looking aggregate colours and colour blends. Many of the aggregates are sourced in the UK and the majority of the aggregate mixes contain recycled aggregates. All the aggregate mixes have been well graded and properly mixed in their correct proportions. Dried aggregates are not essential so there is no necessity for the burning of fossil fuels. It is also possible to recycle existing aggregates as the hydrophilic concentrated formulation can be used in wet conditions.
