Geobarriers
These products are distributed only in the province of Quebec.
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 products 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.

Barriers
SILT CONTROL
Type 1
The Type 1 sediment barrier is a flexible fence composed of woven geotextile preassembled on wooden stakes with industrial staples. The bottom of the stakes is sharpened to easily penetrate the soil and a fold of 150 mm is provided at the base of the geotextile to allow adequate anchoring to the soil. These barriers, installed on the perimeter of the work site where soil is disturbed, are designed to control the migration of soil particles and prevent the contamination of adjacent sites (streams, parking areas, streets, etc.). It is a sedimentation control structure whose goal is to protect the environment and which is required by several water management guides and by the CCDG of the Quebec Department of Transport.
Grade F1 BNQ
The Grade F1 BNQ sediment barrier is a flexible fence composed of a non-woven geotextile preassembled on wooden stakes with industrial staples. The bottom of the stakes is sharpened to easily penetrate the soil and a fold of 150 mm is provided at the base of the geotextile to allow adequate anchoring to the soil. These barriers, installed on the perimeter of the work site where soil is disturbed, are designed to control the migration of soil particles and prevent the contamination of adjacent sites (streams, parking areas, streets, etc.).
Turbidity curtains
TURBITEX (Turbidity curtains)
Turbidity curtains are floating barriers which control dispersion of sediments on lakes and rivers. Made of geotextiles specially selected for the scope of the application and available in different dimensions, these curtains are designed to deviate, contain and promote deposit of sediments which end up in streams as a result of soil reconditioning. The curtains are available in different lengths and can be joined together to form a continuous barrier over the entire length of the worksite. This type of sediment control measure is generally required by regulatory entities during the execution of civil engineering works next to bodies of water.
OIL ABSORBING BOOMS
Oil-absorbing booms are booms designed to absorb and recuperate oil product leaks and accidental spills. The materials used in their manufacturing have particular oil absorption properties while remaining water repellent; as aresult, they are the ideal solution for the recuperation of oil spills on bodies of water. Absorbing booms are a quick and efficient solution for pollution control in natural environments when executing civil engineering works with heavy equipment.
