One of the large families of storage and drainage boards , which is formed by heating and pressurizing high-density polyethylene (HDPE) or polypropylene (PP), which can not only create a drainage channel with a certain three-dimensional space support rigidity, but also can A lightweight board for water storage. Block-shaped, waterproof, water storage, mostly used for roof greening and indoor planting.
1. Storage and
drainage function: The board itself has two comprehensive
functions of water storage and drainage, which can ensure that
excess water is quickly drained, and the water storage part can
store part of the water, which can provide sufficient water and
oxygen for plant growth.
2. Strong load
resistance and durability: the board has the characteristics of
extremely high spatial rigidity, and its compressive resistance
is obviously better than that of similar products (which can be
tested by on-site tests), and can withstand high compressive
loads of more than 400Kpa. Extreme load
conditions of mechanical compaction during
backfilling
.
3. The
construction is convenient, the maintenance is simple and
economical.
4. Light
weight and strong roof thermal insulation
function.
1. Mainly used
in roof greening, underground car roof greening, city squares,
golf courses, sports fields, sewage treatment plants, public
building greening, square
greening , road
greening projects in the park, etc.
2. When used
in flower ponds, flower troughs and flower beds in gardens, water
storage plates and filter geotextiles are directly used instead
of conventional materials (such as filter layers composed
of ceramsite
,
pebbles
or
shells).
3. When used
for hard interface greening such as new and old roofs or roofs of
underground projects, before laying the storage and drainage
boards, first clean up the debris on the site, set up a
waterproof layer according to the design drawings, and then
use cement
mortar to lift the
slope to make the surface free. Where there are obvious bumps,
the storage and drainage boards are discharged in an orderly
manner, and there is no need to set up additional blind
drainage ditch
within the
laying area .
4. When used
for building
sandwich panels, the
storage and drainage panels are laid on the roof concrete panels,
and a single wall is built outside the storage and drainage
panels, or protected by concrete, so that the underground water
seeps into the blind
ditch through the overhead space of the
drainage panels .
