TILTEX™ Concrete Blanket - GCCM Flexible Concrete Liner (7mm to 12mm Grades)

TILTEX provides a hard-wearing, hydraulically smooth lining for open irrigation canals, farm channels and drainage ditches. With a Manning's roughness coefficient of n = 0.022, it maximises flow efficiency while eliminating seepage losses and preventing erosion of the channel invert and banks. TILTEX Plus adds full impermeability for zero-loss lined canals. Installation proceeds without dewatering - panels unroll into wet channels and cure to structural concrete in situ. Replaces conventional poured, sprayed or precast concrete at significantly lower installed cost across African irrigation schemes.

TILTEX lines road reserve drainage channels, cut drains, table drains and railway side ditches to prevent scour and structural undermining of adjacent pavements and embankments. Panels install parallel to the ditch profile in a single operation without formwork or batching equipment - critical for linear infrastructure projects covering long distances across remote terrain. TILTEX 9 and above are specified for this application. The non-flammable B-s1 d0 fire classification makes TILTEX suitable alongside active rail corridors and fuel-carrying roads.

TILTEX is installed parallel to slope faces to provide a permanent hard erosion control surface on road cuttings, embankments, spillways and natural slopes where vegetated protection is unsuitable due to high flow velocities, dry climates or poor soil conditions. It replaces shotcrete and riprap while requiring no specialist plant or concrete crew. TILTEX conforms to the existing slope profile before hydration, eliminating the voids and bridging that compromise conventional concrete placement on irregular surfaces. Gripple pins and anchor trenches secure the mat to the slope at design-specified intervals.

Where slope bodies are structurally unstable and at risk of deep sliding, TILTEX replaces shotcrete as the surface element in engineered stabilisation systems incorporating soil nails, rock bolts and ground anchors. TILTEX panels are fixed through the anchor head plate to the stabilisation array, providing a continuous armoured surface that prevents surface erosion, frost action and deterioration of the underlying stabilisation works. All slope stabilisation applications using TILTEX must be designed by a qualified geotechnical engineer.

TILTEX rapidly lines secondary containment bunds at fuel depots, chemical storage facilities, power stations and industrial plants, as well as flood embankments and earth dam faces. It replaces turf - which requires maintenance, cannot establish in dry conditions and presents a fire risk - and eliminates the need for costly cast-in-place concrete on earthen structures. TILTEX Plus provides the waterproofing layer where bund lining must also function as a containment barrier. Anchor trenches at the crest and toe of the bund secure the mat against uplift and sliding.

7,600 g/m² - 7 mm thickness. Entry-level GCCM grade for geomembrane protection, blinding concrete, mechanical protection of underground cables and pipes, temporary waterproofing, ground stabilisation and slope erosion control on moderate gradients. Lowest mass per unit area, maximum coverage per truck.

9,600 g/m² - 9 mm thickness. Extends to road and railway ditch lining, nozzle and culvert recovery, gabion protection, bund lining and slope erosion on steeper gradients. The most widely specified grade for road reserve drainage and rural irrigation schemes across southern and east Africa.

10,600 g/m² - 10 mm thickness. Heavy-duty grade for canal and weir lining, river bank protection, containment pond lining and slope stabilisation under high flow velocities and abrasion. The standard specification for irrigation infrastructure, mining process water channels and municipal stormwater systems.

12,600 g/m² - 12 mm thickness. Maximum standard grade for tailings dam and landfill bund lining, sea and dam swell protection, maintenance access ways on geomembranes, vehicle temporary circulation surfaces and mechanical protection of membranes under reinforcement. Where structural mass and long-term durability are the primary design criteria.

Any grade (7 / 9 / 10 / 12) with integral PE geomembrane bonded to the underside. Fully impermeable - tested to EN 13967:2012 and ASTM D 5887-16. Membrane thickness from 0.2 mm to 2.0 mm in LLDPE, HDPE or PVC. Geomembrane laps are welded (≥ 0.5 mm) or adhesive-taped (thin films). Specified for reservoirs, farm dams, lined irrigation canals, containment bunds and any application where zero seepage is required.
