What is BS EN 14150 - Geosynthetic barriers about?

BS EN 14150 is a European standard that discusses determination of permeability to liquids for geosynthetic barriers. The function of these barriers is to either prevent damage to highway pavements and structures or to contain water or waste materials.

BS EN 14150 specifies a method for measuring the steady-state liquid flow through a geosynthetic barrier, used to contain liquids in long-term applications. The test method and described apparatus allow the measurement of flows accurately down to 10−6 m3/m2/day. In particular, circumstances where testing indicates that values obtained for a geosynthetic barrier lie below the threshold of sensitivity of this test method, then the value of liquid flow is declared as being less than10−6 m3/m2/day.

Note-

Clay geosynthetic barriers cannot be tested with this apparatus.

Who is BS EN 14150 - Geosynthetic barriers for?

BS EN 14150 on a determination of permeability to liquids for geosynthetic barriers is applicable to:

Contractors
Civil engineers
Manufacture of geosynthetic barriers
Environmental protection agencies
Government regulatory bodies

Why should you use BS EN 14150 - Geosynthetic barriers?

Geosynthetics are synthetic products used to stabilize terrain. They are generally polymeric products used to solve civil engineering problems. The polymeric nature of the products makes them suitable for use in the ground where high levels of durability are required. They can also be used in exposed applications.

BS EN 14150 discusses the principles of hydraulic pressure which is applied between the two sides of a geosynthetic barrier.

BS EN 14150 describes the procedure in which the upstream pressure is maintained higher than the downstream pressure during the whole duration of the test and between each stage.

Using BS EN 14150 you can determine the permeability to liquids in geosynthetic barriers which will allow you to improve the quality of the geosynthetic barriers.
