Green Roof Saturated Weight

Always ask a manufacturer or installer to provide you with the maximum saturated weight of the total green roof system.

Green roof saturated weight. Intensive green roofs are essentially roof gardens and may also need to allow for the additional weight of paving and terracing furniture and even trees. Pre grown trays extensive growing media. If necessary this weight can be reduced to approximately 40 kg m for roofs that can only bear a lightweight green roof system. Cuttings for plant material weight.

Holds up to 9 litres of water per square metre so saturated weight is 9kg m2. Think about the saturated weight this way. The venny green roof has shallow substrates on two types of roof the first roof is on shipping containers and is designed for a dead load of 250kg m 2 and live load of 100kg m 2. System depth dry weight saturated weight.

The green roof solution uses a unique lightweight growing media rather than soil and as a result is less than 8 cm thick and six times lighter than traditional systems weighing only 20 kg m2 dry or 65 kg m2 saturated.

When saturated with water in the summertime when the plants are at their biggest and heaviest the mats weigh 40 45kg m2. Weight vegetative roof weights can range from 16 to 60 pounds per square foot depending on the depth of the growth medium types of plantings and accumulated weight of other additions such as pavers or water features.

Lightest weight system at just 44kg m saturated weight loading installed directly onto the root resistant waterproofing complete integrated system 11 species of sedum are grown in the blanket to ensure plant diversity. A flat roof built using the enviromat green roof system will weigh the following. That is your starting point. 8 media depth 25 33 lbs ft2 44 52 lbs ft2.

The second trussed roof is designed for a dead load of 160kg m 2 and a live load of 40kg m 2. An interesting example of an intensive green roof is manaton the award winning private house on dartmoor that uses local meadow grass to blend the family home into the landscape. Now fill that same cup to the brim with water.
