Multiline Sealin Brickslot
Introduction to the system

The latest generation of channel drainage systems, ACO Multiline Sealin, has a range of gratings to complement installations which require discreet slot drainage.

Designed as standard with a heelguard 10mm off set drainage inlet, ACO Brickslot is a subtle and unobtrusive grating which when combined with ACO Multiline Sealin galvanised steel channels, can be used as a solution to complement discreet drainage applications and is ideal for use against building facades.image

Compatible with most paving materials, the vertical sides of the grating enable pavements to be laid directly to the units edge. Once installed the system is totally secure and not vulnerable to vandalism or loose gratings. This makes the system suitable for applications such as schools and playgrounds where grating removal can become a hazard.

The channel and ACO Brickslot grating together provide an unobtrusive continuous slot drainage system, with high hydraulic efficiency for fast removal of surface water. Additionally the integrated seal of Multiline Sealin means you are no longer reliant on a secondary sealant application during installation on site.

ACO Brickslot gratings are available in galvanised steel and suitable for use with the 100mm ACO Multiline Sealin range.

The system includes an ACO Brickslot access unit to ensure easy maintenance and access to the drainage system, and the galvanised range are compatible with the range of ACO Multiline Sealin accessories. Multiline Sealin has a comprehensive use of seals throughout the whole channel system including sumps and vertical outlets.

ACO Multiline Sealin Brickslot is suitable for Load Class D 400 applications. This product is not suitable for carriageways of public roads or motorways.
Information on this product can be found in the ACO Multiline Sealin technical literature pages 24-25.
