Project Overview

In July 2024, CCX-MAT^® (CCX-M^®) GCCM was used to line newly installed drainage channels as part of the new A11 Sisak Motorway in Croatia. Originally designed in 2006 and partially built between 2006-2015, this final section of the A11 motorway runs between the towns of Lekenik and Sisak. As part of the new construction, drainage channels were designed to divert rain-water run off from the motorway and its structures and into nearby streams and rivers.

CCX-M^® laid transverse and secured into anchor trenches using U-pegs

Solution

To provide protection from erosion for the new drainage channels, a number of solutions were suggested including pre-cast concrete slabs. As the clients needed a rapid install, low maintenance and long-term solution, pre-cast concrete slabs were dismissed and CCX-M^® was chosen as the prefered solution instead, due to the material having low maitenance requirements and being easier and faster to install.
