Roof Detention System

Instead of running off the roof via gutters and downpipes the water is temporarily stored or allowed to pond on the surface and then released slowly so that it can drain away gradually.

Roof detention system.

Roofblue can do the following. The goal of a detention oriented green roof is to delay peak runoff so that sewage systems have time to drain. It is used for lightweight green roofs terraces and has many functions. A standard sponge roof can be upgraded from a retention oriented green roof to a detention retention oriented green roof for 10 20 m 2 1 2 sqft.

It is made of a filtration veil and the polyamide monofilament fibre network layer. This technique is most commonly used in dense urban areas where other methods of stormwater detention are impractical. Blue roofs are non vegetated source controls that detain stormwater either releasing it more gradually to the sewer system or storing it for beneficial reuse. It has been evaluated and tested by green roof diagnostics.

The liveroof integrated roofblue riser is engineered to provide temporary water detention underneath all liveroof systems. Protection drainage and filtration. Almost all of the rain that falls onto a fully saturated profile will quickly drain through and flow underneath a traditional green roof profile. This roof can then detain 2 5 5cm 1 2 of water for anywhere between 1 10 hours.

Purple roof is the simplest and least expensive solution if you would like a detention green roof. Bauder sdf drainage layer one side laminated version is also avaliable. Rooftop detention is the heart of blue roof technology. It is this delay that what saves us from floods.

When used with control flow drains roofblue expands the usefulness of a green roof system as a stormwater management tool. Thus detention has a time component added. It is a relatively simple concept that results in a controlled flow system of rainwater from the roof. The urbanscape detention green roof is a complete system which consists of a detention layer storage layer a growing media a unique patented rock mineral wool and a vegetation layer.

For a detention facility where the outflow is controlled by means of an outlet orifice tube subject to a head which increases as the depth of storage increases in a storage facility with an approximately uniform area with respect to storage height and for roof detention by means of. All kinds of rainfall can be simulated in this lab. Urbanscape detention layer t5. Reduce the burden on stormwater systems.
