NEW: drainage geocomposite by ABG

Pozibreak uses ABG's cuspated core as it is essential that the void is maintained and that the upper and lower geotextile layers cannot touch each other under the action of the soil pressure Similarly, unless the core is impermeable one side, it is essential that the core does not become totally saturated and therefore that the core has a very high lateral in-plane flow capacity in multiple directions.

There are two forms of Pozibreak

Unperforated Comprising a single-cuspated core with good long term compressive strength, a practically impermeable lower side and a very high in-plane multi-directional flow capacity, laminated to a non-woven geotextile. The geotextile allows clean subsurfacewater to freely enter the core but prevents intrusion of the soil into the core. The core provides the void by the excellent support given to the geotextile and transmits the clean water horizontally to collection pipes. The practically impermeable lower side of the core provides a barrier to the capillary water for added protection in addition to the void. This is a particularly useful feature when saline or contaminated water cannot be allowed to mix with the clean water.

The impermeable core means that saturation of the core void at local low spots can be permitted without risk of breaching the integrity of the barrier.
