Revestimento blindado resistente para ambientes remotos e difíceis
Os projectos mineiros requerem soluções duradouras e fiáveis para o controlo da erosão, proteção de taludes e contenção em ambientes remotos e difíceis. O betão tradicional pode ser lento, pesado em termos de equipamento e difícil de implementar em locais de grandes dimensões. Os produtos Concrete Canvas® oferecem uma alternativa mais rápida e mais eficiente, com controlo de qualidade incorporado. Já é usado pela maioria dos principais extratores de minerais do mundo em projetos na África do Sul, Brasil, Canadá, Chile, Peru, Austrália e Reino Unido. O seu design leve e em formato de rolo permite uma instalação rápida em áreas de difícil acesso, mesmo em climas extremos e locais de difícil acesso.
Principais desafios e soluções
Gestão das águas pluviais
Os produtos Concrete Canvas® proporcionam um revestimento rápido de canais que evita a erosão, a abrasão e a perda de água em locais remotos, tanto para novas construções como para a recuperação de infra-estruturas críticas.
Erosão de aterro
Os produtos Concrete Canvas® proporcionam um controlo duradouro da erosão para aterros de minas e taludes laterais de estradas de transporte em condições extremas e remotas.
Reparações remotas
Os rolos leves dos produtos Concrete Canvas® são rápidos de instalar com um kit mínimo, ideal para locais isolados e de difícil acesso, para a reparação de superfícies de betão.

Exploração mineira
Greenside Mine is a former lead mine within the Lake District National Park. It is surrounded by sensitive habitats including Ullswater. With an annual rainfall of over 2500mm per year, we needed to improve surface drainage to prevent the erosion of mining waste and safeguard the environment. With no access to our site by any tracked or wheeled vehicle, we needed something that could be laid by hand but would provide a long-term drainage solution. CC proved to be the ideal product.

We’ve used CC on a number of installations across Wales… The speed that we can install it and the fact that it can be laid in the rain means we can get in and out of sites quickly and provide our clients with a cost effective concrete solution in conditions and geographies that would be difficult if not impossible to do with conventional options. I think it’s a great product and would have no hesitation in recommending CC being used on similar sites.

As an engineer, I liked the fact that CC was adaptable to changes in channel shape as we had segments of trapezoidal shape that had to transition to a rectangular shape. The drape characteristic allowed the CC to be placed on a pretty rough surface. Finally, it seems that any future damages to the CC will be easily fixed by patching. This should result in very low maintenance costs.

Throughout the design and construction of the Silkstone project Concrete Canvas provided an excellent level of technical and practical advice and support. Everything went as expected during installation of the canvas. The finished product has provided a sound lining system to the refurbished lagoon and reed bed which will greatly improve the ability to maintain and desludge the scheme in future years.

We were very happy with the lagoon lining, this installation will become a reference within the Votorantim Group.

The end result is that there would have been an extra zero on the end of the price quote, if we had elected to use Shotcrete.
