FAQ

ViaCon StormWater solutions come with multiple advantages that make them both cost-effective and highly reliable. Installation time is significantly reduced – by up to 80% – due to the lightweight nature of the components and the simplicity of assembly. Maintenance is easy and cost-efficient thanks to standard manholes, which allow access without the need for specialised equipment. Additionally, integrated sand and oil separators ensure that groundwater remains uncontaminated, all while reducing the environmental impact. ViaCon solutions offer up to a 70% lower CO2 footprint compared to similar products made from concrete or plastic.

ViaCon StormWater tanks are versatile and can be used in various settings, including under roads, parking places, and green areas. They are commonly applied in urban environments for flood prevention, groundwater infiltration, and rainwater drainage systems. Additionally, they are ideal for storing firefighting water and supporting industrial processes where effective water management is required. Their durable design allows them to be installed at great depths, making them suitable for demanding hydrological conditions.

ViaCon StormWater solutions provide a clear advantage over alternative options such as reinforced concrete, plastic, or fiberglass tanks. They offer excellent strength and can withstand heavy soil loads and external forces, enabling installation at significant depths. Unlike plastic tanks, ViaCon’s steel tanks do not require load distribution plates, simplifying the installation process and reducing costs. Additionally, their superior anti-corrosion protection ensures long-lasting performance, making them a durable and reliable choice for modern infrastructure.

Sustainability is at the heart of ViaCon’s StormWater solutions. The tanks are made of recyclable steel, one of the most sustainable materials available, with proven durability for up to 120 years, even in aggressive environments. By integrating oil and sand separators, they help prevent groundwater contamination, supporting clean water systems. Compared to alternative materials, ViaCon solutions reduce carbon emissions significantly, contributing to climate action goals and sustainable construction practices.

ViaCon StormWater tanks are manufactured from high-quality spirally corrugated steel pipes, ensuring superior strength and durability. These pipes are coated with a 42μm zinc layer to prevent corrosion, in compliance with EN 10346 standards. For additional protection in highly aggressive environments, a polymer coating of at least 250μm can be applied, further enhancing resistance to corrosion and extending the product’s lifespan to up to 120 years.

ViaCon solutions are fully customisable to meet the unique needs of each project. Whether you require specific tank dimensions, fittings, or integrated systems for water storage, infiltration, or drainage, ViaCon offers tailor-made solutions. The ability to combine multiple functions, such as retention, infiltration, and carrier piping, into a single system ensures maximum efficiency and cost-effectiveness.

We design our tanks to withstand many vehicular loadings: Following the Eurocodes LM1, LM2, LM3, and/or BS5400 HA/HB loading. HA loading consists of a single wheel load of 100kN.

This depends on application and site conditions, guidance can be found on the downloads tab of our website. Height of cover is the distance between the top of the pipe and the finished ground level. The minimum cover depends on the pipe diameter, the load case, and the design life for corrugated steel pipes.

This is a mix of experience and calculation. We know that steel is long-lasting and durable. The Eiffel Tower has stood for over 130 years, and the Sydney Harbour Bridge for nearly 100 years. For buried steel structures, engineers predict durability through a combination of environmental analysis, engineering methods, and correct material selection. The results are backed by recognized formulas and calculations.

HelCor (corrugated steel) pipes achieve a design life of 120 years for highway structures. For many commercial projects, the standard design life is 60 years. Increased design life can be achieved with methods such as greater steel thickness or a secondary polymer coating.

All corrugated steel pipes are galvanised for enhanced corrosion protection. When ground conditions are aggressive, we can provide pipes with an additional secondary polymer coating for greater durability.

All attenuation tanks have a 60-year design life, which can be extended to 120 years with an additional trenchcoat coating to the galvanized steel corrugated pipe.

This question often arises in railway projects. The backfill surrounding the structure has its own resistivity, though it is often overlooked. To protect the culvert itself, we employ a polymer coating that offers insulating properties and significant resistance to stray currents. This ensures the structure remains protected against the corrosive impact of stray currents.

Galvanised steel allows for sacrificial steel over time. If the surface is damaged, it can be repaired using two applications of zinc-rich paint and a third maintenance coat to restore protection.

The outside diameter depends on the corrugation profile used. H68 profiles range from 300 mm to 1200 mm and add 26 mm to the pipe diameter. H125 profiles range from 1200 mm to 3600 mm and add 50 mm to the pipe diameter. Manufacturing tolerances also apply.

In the UK, many contractors have extensive experience installing ViaCon StormWater Tanks. As a company, we provide support through toolbox talks before installation and aim to visit sites during the installation to ensure contractor confidence. We are also happy to provide seminars to explain ViaCon solutions.

ViaCon UK’s attenuation systems primarily focus on attenuation or infiltration and have no specific maintenance requirements. Regular inspections during the first 12 months are recommended to assess environmental conditions and determine a suitable maintenance regime.

Installation time varies depending on project size. Smaller projects can take a day, while larger ones may take a couple of weeks. Compared to other solutions, ViaCon tanks are quick and simple to install.

Delivery times typically range from one week for small projects to around eight weeks for larger or complex projects. Delivery depends on project size and factory workload. ViaCon delivers goods to the construction site, while site personnel handle off-loading. Full terms and conditions are available upon request.
