Water retention

Lightweight effective water storage solutions for green roofs

With advanced green roof technology, you can increase water storage capacity and keep the system weight low.

OUR SOLUTION

Xeroflor's lightweight materials capture rainfall and filter out pollutants – so there’s less run-off, and it’s cleaner.

Lightweight and highly absorbent

Lightweight and highly absorbent

The saturated weight of water-retention layers is on average 25% lighter than typical growing media. So replacing all or part of the growing medium in a green roof with water-retention materials, such as fleece or hygroscopic mats, can improve water storage while keeping the system weight low.

Stormwater management and flood prevention

Many cities require a green roof to retain a specific amount of rainfall in their stormwater management plans to prevent flash flood and combined sewage overflow. Our XF Retain water retention products can be incorporated into any green roof to increase water storage without incurring significant weight.

High performance and durable

High performance and durable

Unlike dimple and reservoir drains where stagnant water is stored in isolated "cups", our XF Retain stored water uniformly directly below the growing medium or vegetation mat for easy access by plant roots. Plus XF Retain is made of durable materials that do not rot or decompose over time.
