Geocomposite drainage material in the form of a three-dimensional diamond-shaped grid bonded to nonwoven geotextile on both sides.
Hydromat 3D
Compared with Hydromat 2D, which is bonded to nonwoven geotextile on only one side, the 3D grade has greater thickness and, consequently, higher tensile strength and water permeability.
Advantages of Hydromat 3D:
- Comparable in water permeability to a 15-centimetre layer of crushed stone
- One roll can replace 25 tonnes of crushed stone
- Retains its properties under high pressure
- Reduces costs associated with soil excavation and crushed stone placement
- Easy to install without construction equipment
- Resistant to aggressive substances
- Environmentally friendly
Areas of application
The material is used for the installation of drainage and water disposal systems.
- Erosion protection for slopes and embankments
- Installation of horizontal and vertical (layer) drainage in the construction of drainage systems for geotechnical facilities
- Installation of gas drainage during the construction and remediation of landfills for waste disposal
- For wall drainage and protection of the waterproofing of buried structures against mechanical damage
