Geomembranes PEAD - Numapol PEAD
High density polyethylene geomembranes HDPE
High density polyethylene geomembranes HDPE are used as a waterproof barrier for all types of hydraulic work like water reservoirs for agriculture, canals, treatment plants, settling ponds, evaporation ponds, farms, golf courses etc
This type of polyethylene geomembranes are used in projects related to the environment as a barrier to contain liquid or solid contaminants such as waste landfills, leachate, slurry, mining waste, protection against leaks in petrochemical industries, airports, harbours, etc..
They are used as well in civil engineering in railway constructions, roads, walls, tunnels, pavements, etc.
Complies with the UNE EN-13361/2-13491-13492/3-15382
NUMAPOL HDPE geomembrane is manufactured by extrusion in a flat die and calender, made from high density polyethylene premium (97.5%) and carbon black (2.5%) plus antioxidants, which gives excellent weather resistance and a high level of stress cracking.
Whay choose Numapol HDPE Geomembranes?
Our product differs from others to care for the details that our customers ask for, for example, in our bobbins we use inner tube of hard plastic which has good mechanical properties, don't crushes and can get wet without get soft and deform, also the plastic inner tube behaves very well on all bobbin unwinding devices on site. Also we mark all the bobbins ( apart printing with ink) with laser engraving so you do not miss the traceability of the blade across its lifetime, each 2 square meter plate has a marking indicating the code of the coil and the meter that corresponds to the total length of the coil. Also we mark all the bobbins (apart printing with ink) with laser engraving so you do not miss the traceability of the geomembrane in its lifetime, every two square meters has a marking indicating the code of the bobbin and the meter that corresponds in the total length of the bobbin. We also printed on the sheet, a reference line to overlap the pieces, as an aid in installation.
Latest technology and the best resins are used in manufacture, providing to geomembrane NUMAPOL very good mechanical properties (tensile strength, elongation, tear and punching), chemical properties (resistance to organic solvents and inorganic) and a good weldability.
Apart from black geomembrane can manufacture to order in green, blue or beige.
We produce PE welding rod for polyethylene extrusion also we can supply PE granulate.
We supply polyester or polypropylene geotextiles in different weights and sizes.
We manufacture polyethylene profile for anchorage to concrete.
We produce VLDPE geomembrane, polyethylene ultra flexible. Indicated for work that requires greater flexibility. Presentation is in rolls 1.5 m wide.
We supply geodrains composed of a polyethylene geonet plus one or two attached geotextiles.
