The retail and commercial sector offers a variety of challenges for surface water drainage. New developments such as supermarkets and shopping centres are often integrated with offices and commercial buildings such as warehouse units.
Due to the complexity and arrangement of these areas, specifying the correct commercial drainage system for the demand of each application area is essential.
Shopping centres, retail parks and supermarkets can cover a variety of different surface areas from car parks to pedestrian surfaces. Commercial drainage systems have to overcome different challenges when installed within these areas:
Car park surfaces are constantly trafficked by a variety of different vehicles every day. The instilled drainage system have enough durability and resistance to withstand high volumes of traffic, different loads and dynamic forces.
Depending on the car park location, the surfaces can also cover a large surface area. A system with high retention capacity may also need to be considered, if surface water needs to drain an extensive catchment area.
Retail stores and supermarkets often have external yards for offloading transported goods. These areas are trafficked by load-bearing and dynamic forces from transportation lorries and forklifts.
A robust and heavy-duty drainage channel should be specified within this areas to withstand the heavy loads and lateral forces imposed on the system.
Supermarkets often have their own adjoining petrol stations. The forecourts are subject to high volumes of traffic from cars, vans and fuel tankers. This type of application can also bring a high concentration of contaminates such as hydrocarbons, petrol, diesel and oils.
An effective drainage system for a petrol station forecourts must have the capability to cope with different traffic loads, as well have a high level of resistance to chemicals.
Drainage channels situated within public spaces can demand to have a a higher visual aesthetes for the overall design.
The selection of gratings with appropriate colours, decorative detail and special materials allows the channel to discreetly fit into the existing space and make a statement designed gratings.
”When considering the correct channel proposal for a commercial project, it is essential to understand the exact type of traffic expected and the dynamic forces applied to the channel. This will determine the correct weight loading, grating type and locking system required.”
Urban retail outlets, town centres and office complexes can be situated around large open spaces interlinked with modern and traditional architectural buildings.
Incorporating commercial drainage channels that combine efficient hydraulic performance and also look aesthetically pleasing can be beneficial.
The installed surface drainage system requires a strong and robust solution to withstand regular heavy traffic and dynamic forces imposed by vans, lorries and forklift trucks.
Parking spaces require a durable channel system which covers the weight load requirements as well as pedestrian safety.
Due to increasing surface sealing, heavy rainfall can quickly lead to large amounts of surface water. The drainage system must be able to intercept and divert the high volumes of rainwater.
In urban areas the safe retention and treatment of substances that are hazardous to water (e.g. hydrocarbons, metals etc.) must be removed. Filtration channels not only drain surface water, but also filter pollutants before returning it to the natural watercourse or the drainage network.
The installed surface drainage system should have a long service life with a maintenance and cleaning programme.
Buildings need to be protected from rainfall or standing water. The surface drainage system needs to quickly and effectively drain any excess water left from rainfall to protect the fabric of the building and ensure optimal pedestrian safety.
There are many factors to consider when planning and specifying retail and commercial drainage. Therefore, HAURATON endeavour to make sure you have the right solution to suit your application area. The channels below are recommended for retail parks, supermarkets and other commercial areas.
