Main Applications: Drainage Channels

COLETANCHE® SC1, is the latest addition to the COLETANCHE® line. This reinforced elastomeric bituminous geomembrane is specially formulated to provide a reliable, cost-effective solution for waterproofing roadside and highway ditches that complies with European Union water legislation (stormwater runoff) aimed at protecting groundwater.

 

Guaranteed compatibility with hot asphalt mixes
 

The bituminous content of COLETANCHE® SC1 ensures full compatibility with hot asphalt mixes (macadam). It provides uncompromising watertight integrity at the top of the ditch during the application of the hot asphalt mix (macadam) with no extra protection required, unlike polymeric membranes, which deteriorate under the effect of heat and require added protection.

 

The easy-to-handle “all-terrain” geomembrane
 

Minimal risk of wind uplift

With its 2.5 kg/m² (74 oz/yd2) surface mass and the resistance inherent to bituminous geomembranes, COLETANCHE® SC1 frees users from the need for woven geotextiles (base sheet and added protection) and minimizes the risk of wind uplift during geomembrane installation.
 

Weldable in all weather conditions; no special equipment required

Flame welding using propane torches simplifies worksite organization by ensuring quick and easy installation. The torch-on technique can be used in wet and cold weather, unlike the hot air welding required by polymeric membranes.

The practical benefits of an “all-in-one” geomembrane
 

Internally reinforced COLETANCHE® SC1 does not require the installation of a puncture-resistant geotextile. The sanded surface provides an excellent friction angle and can in most cases be covered directly with soil with no need for geogrids.

 

Made to measure for waterproofing drainage channels
 

Available in a selection of widths (from 2.50 m to 5.10 m - from 8.2 ft to 16.7 ft), COLETANCHE® SC1 adapts to your worksite and optimizes efficiency by reducing the number of unrolling and overlapping operations. Since it is installed lengthwise, COLETANCHE® SC1 also reduces the number of transversal waterproofing joints (one joint every 150 metres or 164 yd on average).
 

Maintenance is minimal and straightforward: In the event a repair is required, simply weld a patch of the same product to the damaged area

 

Quick and easy to install as waterproofing and asphalting work advances
 

SC1 is mounted on sturdy steel mandrels, which makes the membrane easy to manipulate and unroll using a manual or hydraulic beam.

 

The case for COLETANCHE® SC1
 

An affordable and effective alternative to polymeric membranes

• Just one product to install. No geotextile on the bottom or top surface means time savings on material procurement, delivery, and installation

• The right width for your project. “Tailor-made” widths mean COLETANCHE® SC1 can be installed immediately; no need to cut or fold to fit

• Simplified preparation of excavated material.

Clear advantages

• For installers. Quick and easy to install in all weather conditions, compatible with hot asphalt mixes (macadam), simple to repair.

• For operators. Installs directly on the support, no puncture-resistant geotextile required, minimizes the risk of wind uplift, won’t hinder traffic in the vicinity after installation.

• For main contractors. Guaranteed waterproofing, minimum number of joints, superior mechanical impact resistance, easy to repair, economical to maintain.
