Green Roof Soil Depth

This is especially true of intensive green roofs which can have soil that is two feet deep or more.

Green roof soil depth.

Liveroof engineered green roof soil weighs approximately 27 to 29 lbs sq. Its soil depth is a full 2 inches enough to support many low growing succulents and a limited number of accent plants. Sports turf requires a designed soil or growing medium to ensure effective drainage and a substrate. The lite system is typically used on retrofit projects when the roof is engineered with only 15 to 17 pounds per sf for the green roof component.

These require irrigation and a substrate depth of at least 200 mm. Some green roofs are constructed specifically to support sports turf. Plants for green roofs with a soil depth of 100mm plants for green roofs with a soil depth of 150mm so seize the opportunity to elevate your planting to a whole new level with our pick of plants for a soil depth of 50mm. Last for many decades.

The surface and play requirements are much more demanding than for amenity turf. The structural engineer must factor in the weight of completely saturated soil since the plantings and the soil will hold a significant amount of water. Liveroof soil specifications will vary somewhat depending on region and available components. It is generally not recommended for hot climates.

Careful species selection is needed to ensure outcomes can be met. Intensive roofs which are thicker with a minimum depth of 12 8 cm 5 1 16 in and can support a wider variety of plants but are heavier and require more maintenance and extensive roofs which are shallow ranging in depth from 2 cm 13 16 in to 12 7 cm 5 in lighter than intensive green roofs and require minimal maintenance. It is also important to factor in the type and lifetime of the roof membranethat will be used. Fully saturated at 4 depth when fully vegetated with liveroof plants.
