- Reduced environmental impact and transportation costs by avoiding the use of a primary resource.
- Proven record on a number of high-profile projects in the Middle East where it was extensively used.
- Successfully replaces the traditional 300mm layer of crushed stone to intercept the groundwater and allow successful cultivation.
- Ideal for soft landscaping in areas with saline groundwater, to prevent damage caused by the capillary rise of saline groundwater into 'sweet' soil zones.
FAQs
The term “The Original Salt Barrier” refers to specifications rooted in the legacy of thermally bonded geotextile-based Salt Barrier product, developed through extensive trials, field applications and technical approvals across major Middle Eastern countries, where salinity is a critical challenge for civil infrastructure and landscaping projects. The product is supported by numerous project references, proven performance, and stringent quality and process certifications, including Integrated Management System (IMS) and CE Certification.
Terrapro Salt Barrier builds on this established foundation with a specially developed, hydrophobically enhanced, fibre-based thermally bonded geotextile, engineered for reliable performance in demanding saline environments. Its enhanced hydrophobic properties address limitations observed in needle-punched alternatives, supporting long-term effectiveness.
Terrapro Salt Barrier is recommended for construction projects in areas with a shallow water table, where saline groundwater may migrate vertically or laterally and adversely affect soil conditions, planting areas, landscapes, and pavement structures. It provides an effective barrier against salt migration and helps protect against its long-term effects.
Terrapro Salt Barrier is suitable for applications where protection against salt migration and saline groundwater is required, including:
- Landscaping and planting areas – to protect soil and vegetation from salt intrusion.
- Roads and pavement structures – to limit upward migration of salts into pavement layers.
- Green spaces and parks – where saline groundwater may affect soil quality and plant growth.
- Golf courses and sports fields – to protect the root zone from salt accumulation.
- Nurseries and horticultural areas – for maintaining suitable soil conditions for plant growth.
- Urban landscaping and roadside plantations – particularly in areas with shallow or saline groundwater.
- Irrigation and water-management zones – where salt migration may adversely affect surrounding soils.
- Coastal and saline environments – where groundwater or soil may have elevated salt concentrations.
Terrapro Salt Barrier acts like a one-way valve. It allows water from above, such as rainwater, to drain downward while resisting the upward capillary movement of saline groundwater. This functionality is further enhanced by its specially developed bottom layer incorporating a hydrophobically enhanced geotextile, which helps restrict the upward movement of saline water and associated salt migration.
Yes. Terrapro Salt Barrier can replace thick granular barrier layers, reduce excavation depth, material consumption, transportation costs and installation time while deliver consistent performance.
Yes. Depending on the project specific requirements, Terrapro Salt Barrier can be integrated with additional geotextile layer for protection or separation function, Geocells for stabilization solutions to provide a complete ground engineering system.
Terrapro Salt Barrier is engineered with a focus on two important properties i.e. mechanical durability and controlled hydraulic performance, which are critical for long-term performance in saline environments.
Mechanical durability
| Property | Terrapro Salt Barrier |
|---|---|
| Tensile Strength | 30 kN/m |
| CBR Puncture Strength | 5000 N |
The higher mechanical values provide greater installation survivability, higher resistance to site damage and improved long-term structural integrity.
| Property | Terrapro Salt Barrier |
|---|---|
| Waterflow @ 20 kPa | 0.50 l/m/s |
| Waterflow @ 200 kPa | 0.25 l/m/s |
TERRAPRO 1BZ is an impermeable geocomposite designed primarily for waterproofing and drainage applications, combining a polyethylene barrier layer with a nonwoven geotextile. TERRAPRO Salt Barrier is specifically designed to control capillary the migration of salts and moisture in soil, making it suitable for applications where protection against salt intrusion is required.
