Green roof growing media is an integral part of a functioning.
Green roof depth soil.
This is because they provide ecological benefits aesthetic value and creative urban architecture.
Liveroof engineered green roof soil weighs approximately 27 to 29 lbs sq.
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.
When designing a green roof there are several factors to take into consideration.
Replacing the impervious surface of a conventional roof with.
Garden roof assembly hydrotech s garden roof assemblies combine the proven performance of our monolithic membrane 6125 roofing waterproofing with proven green technology.
It is generally not recommended for hot climates.

Growing mediumis the foundation for your plant growth and depending on the types of plants you want to have on your green roof the depth of the soil will need to be taken into consideration.
Consult your local grower for specifics.
It is also important to factor in the type and lifetime of the roof membranethat will be used.
Some green roofs are constructed specifically to support sports turf.

The planting medium in extensive green roofs ranges from 1 6 to 6 inches deep and while deeper systems have been installed they are not favored as much as the shallower systems drought tolerant sedums succulent plants and grasses are the typical plants used since they are shallow rooted and use little water plant diversity on these roofs is kept low to simplify care and to be sure all plants have similar moisture requirements.
These require irrigation and a substrate depth of at least 200 mm.
The soil can range from under 6 inches extensive to a few feet deep intensive.
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.
