High performance drainage mat for pavers and hardscape

All EnkaDrain product variants for pavers and hardscape drainage are multifunctional three-dimensional composite materials. They consist of a durable drainage layer sandwiched between two strong, but lightweight nonwoven filter fabrics. To avoid the filter intrusion phenomenon, the space between contact points of the core and filter is small compared to other types of drainage geocomposites.

The drainage layer itself is composed of tough synthetic monofilaments. These are pre-shaped into a U-groove or V-shape configuration. The result is a pressure-resistant open structure with 95% of void space.

To optimally comply with local building norms, the EnkaDrain product portfolio for pavers and hardscape drainage includes variants designed for specific regions. They all can be installed quickly and easily. And thanks to the polymers applied they possess outstanding resistance to all chemicals commonly occurring in the soil.

Securing a well-designed drainage system is a major task that can be fulfilled by geocomposites. Due to the expected traffic loads, high compression resistance is one of the main factors to be taken into account when choosing a suitable product. EnkaDrain can replace up to 30-40 cm thick gravel drainage layers. This results in less excavation and substantial cost and CO2-emission savings related to the sourcing as well as transport of granular material. Therefore EnkaDrain is the preferred choice of an increasing number of engineers and contractors. It is compression resistant enough to guarantee high flow rates even under the highest loads. When installed in parking roofs the drainage mat not only provides a drainage system, which prevents the infiltration of rain water. It also protects the waterproofing layer.

At the same time, EnkaDrain ensures decoupling between the waterproofing layer and the upper concrete layer. The drainage mat so reduces the risk of humidity in the concrete structure. EnkaDrain is lightweight as well as easy to handle and install. It can be cut with a pair of scissors. Thanks to its flexibility, the drainage mat can be applied with precision even in corners or at pinch points.
