Laterlite Drainage And Moisture Retention In Green Roofs
DRAINAGE AND MOISTURE RETENTION IN GREEN ROOFS
DRAINAGE AND MOISTURE RETENTION IN GREEN ROOFS
Drainage and moisture retention layer, which is placed at the base of the system, above the waterproofing and before the substrate is laid, is essential for the proper functioning of a green roof.
information
RETAINS MOISTURE
The pores within the granules have very good water retention (up to 30%) and releases it slowly, giving plants a valuable water reserve that ensures their long-term health and reduces water stress in hot weather.
BRAND
Laterlite
PRODUCTION
Made in USA
GOOD DRAINING ACTION
The dense network of voids between the granules (55 %) optimises the run-off of excess water and prevents damage from water stagnation.
PERVIOUS CONCRETE
Ultra-light pervious concrete based on expanded clay, such as Latermix Cem Classic, can be used as a highly stable porous permeable layer that allows rainwater to run off freely following the slope of the substrate. It can be used as a drainage layer under hard-paved transit routes or recreational areas, or below small buildings, supported by the drainage layer.
LIGHTWEIGHT
It is lightweight, which helps to avoid overloading the structure of the building
SIMPLE AND QUICK
It is simple and quick to put in placeas a granular material that is laid loose and is easy to level
STRONG, STABLE, AND DURABLE
It is strong, stable, and durable: will not deform, break, or become compacted over time, and is resistant to freezing and high temperatures.
MATERIAL
Clay & Concrete
ENVIRONMENT
Outdoor
DRAINAGE LAYER
To construct a drainage layer of this type of the expanded clay is laid on the waterproofing and a filtering layer is placed on top, separating it from the substrate above. The thickness of expanded clay will depend on the climate and whether the planting system is intensive or extensive.
