1 KERB type SK A combined KERB and CHANNEL drainage system IMC SK EN

2 ERB STORA-KERB is a two-part KERB and CHANNEL drainage system that is designed to be used in a wide variety of locations: roads, highways, car parks, industrial estates, roundabouts and all other kerbed areas that would usually be drained by means of gullies or standard drainage channels with gratings. The channels and kerb tops of the STORA-KERB system are produced in a high-strength polyester concrete material. The use of polyester concrete gives several advantages such as: Lightweight components which result in a faster, simpler and more economical installation. Smooth internal surfaces that ensure an optimal evacuation of surface water. High resistance to frost, salts and hydrocarbons guaranteeing a long lifespan for the installed drainage system. The wide range of available kerb top units seamlessly integrates with the traditional STORA-DRAIN channel drainage system, which has proven its effi ciency and reliability over many years. The STORA-KERB top unit also uses the same tongue and groove jointing system as the channel, which simplifi es the installation and alignment of both channel and kerb units. STORA-KERB is manufactured in accordance with the regulations of EN1433. When the system is installed in accordance with the instructions given in this brochure, D400 loading is achieved. STORA-KERB design conforms with subsections 1-7 of clause 516 of Specifi cation for Highway Works - Series, the product performance specifi cation published by the Highways department (UK) in The Manual of Contract Documents for Highway Works (MCHW). 2

The concrete surround fi lls the recesses on both sides of the kerb tops and ensures a solid installation. The kerb has a Half Battered (HB) profi le and the upstand is 120mm to match a standard HB 2 kerb profi le. The kerb tops should be installed directly adjacent to each other on top of the channel units. If there is a gap at the end of the run, it should be fi lled with a cut section of a standard or a blind kerb top (1). When installing the kerb tops, sliding the tops back and forth on the channel will wear the centring guides and ensure a perfect levelling and alignment (2) H 5

A PVC pipe can be inserted after removal of the PE insert and used to connect two channel runs or to create an outlet if a gully cannot be installed due to depth restrictions. 9

10 ERB STORA-KERB CAPACITY The STORA-KERB is a fl exible and high capacity channel drainage system. The choice between the different available STORA-DRAIN drainage channels will be made based on the STORA-DRAIN capacity calculation program.

11 KERB INSTALLATION & MAINTENANCE GUIDELINES The STORA-KERB system is installed in accordance with the requirements of. The system conforms to D400 load class requirements, when installed exactly in accordance with the details given below. The channels and the gully base are installed, aligned and levelled on a concrete bed (min. requirements: thickness 200mm / C25 grade). The kerb tops can be installed at the same time as the channels or at a later time, if there is a danger of damage from site traffi c. 120 It is important to pay special attention to the installation of the concrete coating at the rear of the kerb tops as this will absorb most of the impact when the system is hit by traffi c. The 200mm width of surrounding concrete shown is the minimum requirement. Concrete should be brought up to a height no greater than 80mm from the top of the rear of the kerb unit, even in landscaped areas. If block paving is being used behind the kerb line then the blocks immediately adjacent to the kerb top should be bedded on concrete All channels and kerb tops are installed without the use of jointing surrounding material. The tongue and groove system on the channel and kerb tops, combined with the concrete haunching, will give a good watertightness. If there are special requirements on the watertightness of the system after installation, please contact us for further advice. The fi nishing of the asphalt layer is to be performed with care to avoid damaging the kerb tops while compacting. The fi nished level will be at 120mm under the kerb top face to ensure a good infl ux of surface water through the drainage openings. After installation, the complete system should be cleaned and all sand, gravel and tarmac residues are removed from the channel system. The cleaning can be performed by a high-pressure cleaner. Access to the channel is possible through the access units and the covers on the gully tops. Maintenance of the system should be performed regularly after installation. The time scale is based on the local situation (sand, leaves, rainfall, traffi c...). 11
