Geomembranes
These products are distributed only in the province of Quebec.
Geomembranes are generally made of thermoplastic materials such as polyethylene, polyvinyl chloride and polypropylene. They are developed to satisfy the design requirements of waterproof water-barrier systems. Several specialized geomembranes can, in addition to making works waterproof, meet particular needs such as increased chemical resistance, resistance to low temperatures, compatibility with drinking water, etc.
Main geomembrane product lines
Thermoplastics
TM200 (Polyvinyl chloride - PVC)
Geomembranes of the 200 series are made of flexible polyvinyl chloride resin (PVC). PVC membranes are characterized by their very high elasticity and their excellent resistance to acids, alkalis and alcohols. Although more flexible than polyethylene geomembranes at ambient temperatures, PVC presents certain flexibility constraints and becomes more fragile at low temperature. PVC geomembranes can be welded on the worksite with specialized equipment or factory-assembled to form large-sized panels. These geomembranes are available in different grades, compatible with aquaculture or drinking water and in various thicknesses according to the needs of your application.
TEX-O-FLEX
Tex-O-Flex is a product invented by Texel, composed of a PVC geomembrane extruded on a PVC geomembrane to create a geocomposite for protection around manholes. The PVC geomembrane of TEX-O-FLEX minimizes the friction between soil and concrete and prevent the movement of concrete sections. The geotextile component of TEX-O-FLEX, in contact with the manhole, dispels any water inflows. This product is a cost-effective solution that minimizes the damage caused to the road network and increases the manholes life.
TM400 (High Density Polyethylene - HDPE)
The HDPE used for the TM400 series is the most resistant member of the family of polyethylenes because of its dense configuration (> 0.94 g / cm3). It offers a great protection against ultraviolet and resistance to aging due to the intense meteorological conditions. Even though it is less flexible than its LLDPE counterpart, it still offers great elongation properties allowing a deformation of 12% of its elastic limit.
TM800 (Linear low density polyethylene - LLDPE)
Geomembranes of the 800 Series are made of low-density polyethylene resin (LDPE). Polyethylene is the most multipurpose thermoplastic for waterproofing applications. It has properties that optimize costs, provide mechanical, chemical and ultraviolet resistance in addition to allowing perfect welding between two sheets of the material. LDPE is a polymer with a lower density (< 0.939 g/cm³) than HDPE giving this material greater flexibility. It is therefore used in works where significant settling is expected in the long term. These geomembranes are available in different thicknesses ranging from 0.5 to 3.0 mm with smooth or textured surfaces depending on the application.
Bituminous
TM300
Bituminous geomembranes are multilayer geosynthetics used for their waterproofing properties and their resistance to chemicals thanks to their elastomeric-bitumen base made up of several layers of geotextiles which give them the mechanical properties required as to perforation, tension and tearing. This type of geomembrane allows perfect waterproofing when quality welding is performed. Often used in projects where installation conditions are more difficult, installation by specialists and control of the welding conditions are required for maximum performance.
Bentonite
TM600
The geomembranes of the TM600 series are bentonitic geocomposites that can form an effective hydraulic barrier. These geomembranes are composed of geotextiles and contain a uniform core of bentonite clay granules that are assembled by a needlepunch process. Thanks to their composition and their manufacturing process, the TM600 geomembranes provide superior waterproofing to natural clay with all the advantages of a technical roll product.
