Product information L-Stone green roof

A green roof is far more than just an architectural trend. In the wake of climate change, increasing urban density and growing environmental awareness, green roofs are becoming ever more important. They create natural retreats, improve the microclimate, promote biodiversity and support intelligent rainwater management. Intensive greening, in particular, unlocks the potential of underused areas - from residential buildings and office roofs to car park decks and private roof gardens.

To deliver these benefits in practice, the right construction components are key - such as the hanit L-Stone for green roofs, which was developed specifically for this type of application. At 18.4 kg, it is even lighter than our standard L-Stone, which already weighs around a third of a conventional concrete L-Stone. This is a key advantage, as every kilogram matters when working on rooftop structures. Structural capacity is often limited, particularly in the case of renovations, conversions or post-construction greening - so the use of lightweight components becomes all the more important. The low weight also makes transport to the roof and installation considerably easier.

As a versatile design element, the hanit L-Stone for green roofs is perfect for urban gardening at height. It is frequently used to border planting beds - whether for growing vegetables, herbs, or as a decorative edge for ornamental plants. It’s also a practical solution for clearly separating walkways, recreational areas or different zones on a roof terrace. Function and aesthetics go hand in hand here - for a green roof that is both structured and visually appealing.

With a width of 80 cm and height options of 30 cm or 40 cm, the L-Stone offers flexible design possibilities for edging on intensive green roofs. Simply rotating the stone allows different height levels to be created on the roof surface, adding visual interest. The ease of working with hanit is particularly helpful when forming corners: clean transitions can be made easily without any special tools or extra connectors.

If you are looking for a low-maintenance, reliable solution for green roofs, our hanit L-Stone is the perfect choice. It is dimensionally stable, weather-resistant and requires no painting or sealing. Its modern grey finish ensures a sleek, contemporary look that suits a range of rooftop designs that will endure over time.

The hanit L-Stone also sets a benchmark for sustainability. Made from 100% recycled plastic and fully recyclable, it supports the creation of environmentally responsible and future-ready green roof projects - combining performance with purpose.
