Simple to install capillary-break layer providing environmental benefits

A significant number of construction projects is being realized in areas with high groundwater conditions. Here, the water table is close to the base of the structures, such as pavements, railway structures, parking areas, platforms, or embankments. Capillary rise can negatively affect their bearing capacity, stability, and lifespan. Capillary-break layers thus need to be installed. Traditional forms consist of granular material but they are costly, and their sourcing represents a burden on the environment. Thanks to its economic, environmental, and also technical advantages, EnkaBreak is enjoying growing popularity. It is a viable replacement for sand and gravel capillary-break layers.

EnkaBreak is a range of multifunctional geocomposites. Their core is made of durable polymeric three-dimensional monofilaments wet-spun into a highly pressure resistant, yet open V-shape configuration. The core is equipped with separation/filter geotextile fabrics on both sides. To comply with the requirements of different project parameters, these fabrics can be thermally or mechanically bonded. Available with a thickness of four or six millimeters, EnkaBreak is supplied in five meter-wide rolls. This facilitates fast installation. In addition to its function as capillary-break layer, EnkaBreak also acts as a drainage layer which provides a high discharge capacity and allows rainwater to escape in all directions.

How EnkaBreak keeps structures safe and dry

A proven alternative for granular capillary break layers, EnkaBreak effectively mitigates the impact of high or differential groundwater conditions. The geocomposite is installed above the highest level of the water table. Here it creates a horizontal void space, preventing moisture from rising from a saturated subsoil to the built structure. This ensures that foundation layers retain their design properties. The unique design of EnkaBreak safeguards the product’s excellent long-term performance: the combination of a pressure-resistant core with geotextile filter fabrics complying with specific stiffness requirements ensures that the void space remains open over the entire lifespan of the structure. Filter intrusion, a phenomenon where extensible geotextiles are forced into the core of certain geocomposites, is reliably avoided even under the highest loads.

In addition to interrupting capillary rise in soil, EnkaBreak acts as a drainage layer. Its V-shape monofilament core exhibits its highest discharge capacity in channel direction. For maximum performance therefore rolls are laid parallel to any slopes.

Where EnkaBreak is used to replace granular capillary-break layers, substantial savings can be realized with regard to the amount of excavation and quarry material required. This is a win-situation for both the environment and for cost savings. Construction can be completed in a shorter time, and maintenance intervals be extended.

For use in arid regions where saline groundwater levels are relatively high and pavements, building foundations or vegetation need protection against the influences of salt, a special product variant is available: marketed as EnkaSaltBarrier, this capillary break layer includes a hydrophobic geotextile fabric.
