Salt barrier

Is the salt barrier important?

What are salt barriers?

The salt barriers are geosynthetics specially designed for replacing the conventional crushed stone layers by reducing environmental impact. Salt barriers avoid damage that is usually caused by saline groundwater’s capillary rise.

Why are salt barriers used?

Salt barriers are high-performance geocomposites and are the best choice for capillary break layers. It is because the cusped core maintains an open void with excellent support and high compressive strength to geotextile surfaces under soil pressure. Its performance gets boosted up when they are unperforated where the cuspated core’s lower side offers an impermeable barrier to increasing saline moisture. In the arid and desert regions, groundwater is almost saline and the water table usually remains close to the surface. Above the water table, capillary rise brings the dissolved salts much nearer to the ground surface. It results in huge problems for the foundations & vegetation of the building structures.

Especially in the arid zones, landscaping in modern development is at risk. Most of the vegetation becomes intolerant even due to slightly saline water. The moisture of saline has to be avoided from going to the vegetation’s root system. It is vital in that similar way that the irrigation water has a quite minimal salt content to lessen the risk of soil’s salinization. It is necessary for the vegetation to survive if there is a salt barrier in between the clean ground and saline ground. That barrier must offer good drainage.

A good and effective salt barrier must give a capillary break layer in between the clean ground & saline ground. You may ask what capillary layer creates? The capillary break layers make a “void” and thus the capillary rise of the moisture of saline is well-prevented. That salt barrier must get installed much above the water table so that the void never gets saturated by the groundwater. The salt barrier has a great in-plane capacity of the flow.

Features of salt barriers:

Let us dive into the features of salt barriers:

> They replace the system of using the traditional crushed stones

> The salt barriers permit successful cultivation

> These barriers remain unaffected by any chemicals that usually exist in the soil

> The salt barrier are durable and can last for more than 25 years

> Salt barriers have a high impact as well as crush strength

> Salt barriers can be installed with ease

>It protects from salt deterioration

> Salt barriers are made up of polyethene and polypropylene and they are not nutrients for the soil microorganisms. Thus salt barriers do not offer nourishment to insects and animals.

We hope this blog has helped you to gain knowledge about salt barriers and their importance. The salt barriers replace the usage of conventional layers of granules used for the landscaping in places with saline groundwater. Use salt barriers for reducing environmental impact. If you want to redirect the roots down much away from the area of paving, you can also use root barriers, which are mechanical guides for redirection of roots away & down from the hardscapes.
