in 2021, 3 containers of Concrete Mat Cloth were shipped to Philippines.
They are all applied for ditch lining project.
Concrete Mat cloth thickness: 8mm.
Concrete Mat cloth was reinforced by 3D spacer fabric inside, and it is backed by HDPE geomembrane.
It could be used to replaced 3D spacer style cement canvas product.

CONCRETE MAT CLOTH GCCM (CMC)
CASE STUDY-FOR DITCH LINING
In September 2018, Concrete Mat Cloth GCCM (CMC) was specified to line drainage ditches along a 1.8km stretch of the Ditch in the Village, Southwoods Ecocntrum project, Manila, Philippines.
Sections of the channel were beyond the reach of plant equipment and required the manual transportation of the materials
across a narrow bridge and up a steep slope. CC allowed for a concrete solution to line these drainage channel sections where it would have been impossible to use conventional concrete options.
CMC8 was used to line one main ditch and various smaller ditches on site. The main ditch is approximately 1700m in length, 3m in width at the crest, and 1m wide at the base.
In preparation for the installation, sections of the drainage channels were dammed off with water flow directed further downstream, and anchor trenches were cut into the shoulders of the channels. The channels were then cleared of debris and deteriorated sections of geo-textile.
The CMC was unrolled on the flat and cut to specific profile length, before being positioned into the ditch with subsequent layers overlapping the previous by 100mm. The CMC was fixed to the substrate using steel ground pegs inserted through every overlap within the anchor trenches. The overlaps were then jointed using stainless steel screws at 200mm centres.
The CC was installed at a rate of approximately 80m2 per day with a 5 man team (two of the crew laying the material and a third fixing it in place), with a total of 5040 SQM installed. Prior to specification of CMC, stone pitching with a paving slab invert was considered as a means of lining the ditch, but this would have resulted in a considerably longer install further delayed by weather conditions. In comparison, CMC provided a significantly faster and easier installation negating any program disruption due to the weather.
Normally, install rates of over 200m² per day were achieved in often severe weather and poor ground conditions.
CMC has a delayed setting window of 2-4 hours, giving contractors time to install the material in extremely wet conditions without the fear of premature setting.
CC provides excellent resistance to UV degradation, puncture and freeze-thaw action, whilst being resistant to acids, alkalis and sulphates. It has a minimum design life of 50 years for the most arduous of applications and will significantly prolong the life and serviceability of the drainage channels for decades to come.
Hydration was achieved using a bowser and hose combination with spray nozzle attached, after which the anchor trenches were backfilled.
