Drainage Made Easy With Drainage Geonet The Perfect Choice For Various Engineering Applications
Product Introduction
The three-dimensional composite drainage net is a new type of drainage geotechnical material. Its composition structure is a three-dimensional geonet core with needle-punched perforated non-woven geotextiles on both sides.
Product Application
Widely used in landfill drainage, highway subgrade and pavement drainage, railway drainage, tunnel drainage, underground structure drainage, retaining wall back drainage, garden and sports field drainage and other engineering drainage fields
Product Property
♦ Strong drainage: strong drainage is equivalent to one meter thick gravel drainage
♦ High tensile strength: can withstand high pressure load for a long time Corrosion resistance
♦ Acid and alkali resistance: has a long service life
♦ Convenient construction: convenient construction can shorten the construction period and reduce costs
