The unique structure of Concrete Cloth GCCM makes it easy to install for a variety of applications, such as channel lining, slope protection and containment. It can be hung vertically, laid in trenches or cut and formed into irregular shapes. Unlike regular concrete, Concrete Cloth materials can be installed in the rain and other wet conditions, which virtually eliminates project rescheduling. It has a low alkaline reserve and a low wash rate for a minimal ecological impact.
The material is available in three thicknesses that come in bulk rolls or small portable batch rolls.
It is typically used to replace conventional concretes, riprap, shotcretes and some geotechnical fabrics for a wide range of erosion control and protection applications.
The most common examples include: ditch lining, slope stabilization, secondary berm protection, culvert invert protection and geosynthetic liner protection.
When stored in the manufacturer's packaging, Concrete Cloth material can be kept for up to 12 months after shipment without a significant decrease in performance capabilities.
Concrete Cloth material will start to lose its performance capabilities once opened and should be used within a few days to prevent any significant decline. It is a best practice to reseal any packaging after opening it to extend the shelf life as much as possible.
The material can be hydrated using saline or non-saline water, and the water does not need to be potable. The minimum ratio of water to Concrete Cloth material is 1:2 by weight. It cannot be over-hydrated, so an excess of water is always recommended.
Water may be pumped from an available water source in the installation area or trucked in via a water truck. Most contractors choose to bring in water with a water truck or use a local water source.
It is not possible to over-hydrate Concrete Cloth material, but if under-hydrated the material will not reach its full strength and the setting time may be prolonged. The material will fully hydrate underwater from immersion.
The thickness you need depends on the application. Contact us for assistance with your specific application. Widths, sizes and weights/thicknesses are listed on our data sheets and product pages.
Concrete Cloth material is supplied in its natural color, mottled grey. The fiber surface of the material can easily be colored by painting with reputable exterior masonry paint.
