Construction

Alkegen manufactures geotextiles that are permeable technical textiles made of synthetic fibers used in civil engineering, environmental and landscape architecture works to separate, filter, improve drainage, reinforce and distribute loads more evenly on soils and surfaces. They are permanent and insensitive to acids found in a natural state in soil which gives them a lifespan exceeding that of the works they protect.

Our geomembrane solutions are 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.

Geogrids are flexible structures presenting openings of various shapes and sizes used to reinforce the upper foundation layer or even the paving by strengthening them thus extending the lifespan of the works. These grids are made of materials resistant to physical degradation and loss of rigidity caused by chemically aggressive environments. Geogrids resist elongation due to creeping and bear large traction loads.

The Draintube line is a family of patented products offering geocomposites for drainage and filtration made up of regularly perforated minidrains, spaced between two or three geotextile sheets. The diameter and spacing of the minidrains as well as the geotextiles used are selected and validated for each project according to the hydraulic and geotechnical characteristics of the site. The geocomposite is thus optimized in terms of cost and performance. Draintube allows the drainage of liquids and gases in civil engineering applications, sports fields, buildings, landfill cells, polluted soils and mining and gas operations.

Our Geodrains are geocomposites manufactured to evacuate infiltrating water and filter fine particles. They replace and reduce to a minimum conventional and natural underground drainage systems. The presence of geodrains allows economical and ecological replacement of drainage systems made of conventional materials while permitting a better reduction of water content in works, thus reducing one of the major causes of their degradation.

Geovegetation products are natural or synthetic mats designed to minimize the impact of natural elements such as rain, running water and wind on soils. These temporary or permanent solutions specifically chosen due to environmental constraints provide additional protection by reinforcing soil, minimizing erosion and promoting vegetation regrowth.

Geobarriers are designed to prevent the migration of loose soil into drainage ditches and rivers during construction work. Generally, factory-assembled and composed of a geotextile curtain, their use is compulsory almost everywhere in North America. These barriers can also consist of booms immersed in lakes and rivers. The use of this type of product is considered as one of the first best practices for managing erosion and its adverse impacts on the environment. Some geosynthetics are also used as root-control barriers for infrastructure protection.

Our engineered self-supported, scrim-reinforced and TPU coated felts are used in a variety of Cured-In-Place-Pipe (CIPP) applications. We design, test, and produce innovative CIPP materials, such as RAD-FLEX®, having standard and tailored properties. RAD-FLEX® is our scrim-reinforced polyester felt having low longitudinal stretch all the while maintaining radial stretch properties.
