产品介绍：
Drainage boards are made by pressing polystyrene (HIPS) or polyethylene (HDPE) plastic
base plates into conical protrusions or stiffening ribs (or hollow cylindrical multi-holes), which
can withstand long-term high pressure and will not deform as drainage materials. The width is
3 meters and the length is either 10 meters or 15 meters.
Drainage boards can be used in combination with filter layers and geotextiles to ensure that
drainage channels are not blocked by foreign objects such as backfill soil or concrete. The drainage
board integrates drainage into one, successfully resolving the relationship between waterproofing
and drainage. In terms of drainage function and economic benefits, it is superior and reliable to
traditional stone particle drainage and other filter layers.
The application scope of drainage boards
Greening projects: garage roof greening, roof garden, vertical greening, sloping roof greening,
football field, golf course. Municipal engineering: airports, road subgrades, subways, tunnels,
landfill sites. Construction engineering: upper or lower floors of building foundations, inner and
outer walls and bottom slabs and top slabs of basements, anti-seepage and insulation layers of
roofs, etc. Water conservancy projects: reservoir anti-seepage, water storage pool, artificial lake
anti-seepage. Transportation engineering: highway and railway subgrades, embankments and
slope protection layers.
