The Intensive Lawn Retention system solution is an effective way of delaying rainwater runoff and adding it to the natural water cycle through evaporation. As a result, a green lawn can flourish on a roof too. The lawn can either be grown from seed or added in the form of turf. It’s important to identify what the lawn is to be used for from the outset because this governs the type of lawn chosen. The green roof structure and water management option is then selected to suit the lawn type. As a result, the lawn stays green, even during the hot summer months and dry spells.
