Garden roof assembly hydrotech s garden roof assemblies combine the proven performance of our monolithic membrane 6125 roofing waterproofing with proven green technology.
Green roof depth soil.
Liveroof soil specifications will vary somewhat depending on region and available components.
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.
Careful species selection is needed to ensure outcomes can be met.
Its soil depth is a full 2 inches enough to support many low growing succulents and a limited number of accent plants.
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.
The surface and play requirements are much more demanding than for amenity turf.
Some types of vegetation require more soil depth for root establishment.
Careful plant selection and maintenance is needed to ensure annuals do not become weeds on a green roof.
It is generally not recommended for hot climates.
Unlike conventional earth covered structures garden roof assemblies are lightweight and can be installed on a wide variety of new and existing structures.
When designing a green roof there are several factors to take into consideration.
Green roofs or living roofs have become popular over the years.
There are two types of green roof.
The soil can range from under 6 inches extensive to a few feet deep intensive.
These require irrigation and a substrate depth of at least 200 mm.
Fully saturated at 4 depth when fully vegetated with liveroof plants.
Soil structure for green roof media.
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.
This is especially true of intensive green roofs which can have soil that is two feet deep or more.
Sports turf requires a designed soil or growing medium to ensure effective drainage and a substrate.
It is also important to factor in the type and lifetime of the roof membranethat will be used.
Replacing the impervious surface of a conventional roof with.
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.
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.
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.
