Foundation drainage and protection you can rely on

Every variant of EnkaDrain foundation drainage mats is based on the same basic concept: A three-dimensional composite that consists of a drainage core either connected to one or sandwiched between two nonwoven geotextile fabrics. The drainage core is composed of tough synthetic filaments. Depending on the specific product type these are molded into a square waffle pattern, spun dry into a U-groove configuration or looped and fused together where they cross to form a pyramid-shaped structure.

In all cases the result is a material with a voids ratio of 95 %. EnkaDrain is exceptionally flexible, yet compression resistant and very durable.

Traditional drainage layers consist of granular material. However, the performance of such a drain can be inconsistent and difficult to predict with time. Not so the discharge capacity of EnkaDrain. Equipped with one or two nonwoven geotextile filters and therefore insensitive to clogging, EnkaDrain provides a highly cost-efficient alternative to sand and aggregate drains. The geocomposite is designed to relieve hydrostatic pressure from soils abutting below-grade structures. It creates a consistent water path. Water is channeled through EnkaDrain’s drainage core to the discharge system before it ever reaches subsurface walls. The geocomposite prevents the collector drain from silting up with fine soil particles. As such, EnkaDrain keeps the structure safe from foundation cracking, and the inside space safe from mold and other moisture-causing issues. At the same time, EnkaDrain provides an insulating air gap and acts as a protection layer for the waterproofing membrane. That means that the drainage mat prevents construction equipment, sharp rock or debris in the soil from damaging the waterproofing membrane. This is a major advantage during backfilling of the trench.

The EnkaDrain product portfolio also includes product variants for use as lost shuttering or for ground vibration damping
