ACO Multiline is the most comprehensive range of polymer concrete drainage channels with gratings. At the heart of the ACO Multiline system is the idea of providing benefits for all: architects, designers, distributors, developers and builders. Five load classes, six widths, three protective edge materials and the widest range of standard, design or individual gratings - an innovative concept for complete design freedom.

    ACO Drainlock

    Enjoy complete freedom of design with a wide range of gratings with different design, colors and materials - cast iron, composite material, stainless steel or galvanised steel. ACO's innovative production technology allows the implementation of various visions, rich in ideas and personality. Architects have freedom in choosing gratings for drainage gullies, thereby achieving distinctive accents, as well as creating a unique design that corresponds to the particular project. At the same time, optimal drainage and resistance are guaranteed.

    Technical superiority

    The heart of the innovation is the V-profile. This new channel profile improves the drainage capacity and enhances the self-cleansing effect. The new side wall structure and the intelligent distribution of materials considerably increase the load-bearing strength and overall stability.


    The complete tightness of the channel body right up to the top of the edge rails, and the very smooth surface, increase drainage volumes during extreme storms. The ACO safety rebate ensures that the channel body units are connected to one another with a 100 % watertight seal. The new cast-in lip labyrinth seal ensures that the drainage system can be connected with a watertight seal to the drainage pipe system. ACO Multiline® easily complies with DIN EN 1433 specifications with a very large safety margin.

    Creative and versatile Grate options

    The ACO Multiline® V 100 – 500 system solutions have a clearly defined program of gratings suitable for most architectural requirements in terms of aesthetics, functionality and load-bearing strength.

    The Drainlock gratings of the ACO DRAIN® Multiline system offer a wide range of covers in many shapes, colours and materials – made of cast iron or stainless steel, hot-dip galvanised steel or plastic – provide creative scope for individual planning and design.

    The different gratings can be freely combined independent of the channel bodies and are available for all load classes from A 15 to E 600.
