Geocanvas
Non-woven geotextiles (geofabrics) KANVALAN® - start of production in 2010.
KANVALAN® is a registered trademark. KANVALAN® geotextiles (geofabrics) are made of polypropylene using the so-called spunbond technology, fibers bond in the canvas proceeds through thermal bonding and needling.
ADVANTAGES OF USING KANVALAN® GEOTEXTILES
- reliability and durability of road construction;
- simplification of works;
- reduction of the material used for construction;
- improvement of the quality of execution of construction works;
- being highly efficient during the course of construction works in difficult conditions (wetlands, permafrost, cramped conditions of construction, etc.);
The use of KANVALAN® geotextiles (geofabrics) is the basis for reliable, durable, and economical design; engineering and technical solutions in road and railway construction; as well as laying of oil and gas pipelines.
