Pumice is a natural drainage aggregate acting as a soilbuilder to obtain superior playing surfaces for sport and leisure facilities.
The porous nature and rounded particle shape of pumice improves soil aeration, maintains surface drainage, promotes strong root growth and sward resilience.
Pumice is a natural drainage media alternative for golf courses, football and rugby pitches.
