ACO RainDrain® Brickslot B 125

Slot drainage channel for domestic driveways and patios

• Minimalist finish with capacity: The discreet 10mm-wide inlet slot delivers a minimalist surface finish, while the RainDrain® channel beneath effectively drains domestic paved surfaces.*
• Pedestrian and vehicular installations: ACO’s polymer concrete RainDrain® channel and Brickslot grating is suitable for both pedestrian and domestic vehicular installations up to load class B125.
• Two metallic finishes: Brickslot grating and access cover are available in either galvanised steel or stainless steel. Stainless steel offers improved performance and delivers a distinct, high-end finish to paving projects.
• Suitable with different paving products: The offset Bricklot grating is suitable for use with paving products up to and including 60mm thickness and allows installation adjacent to a wall. 

Deliver comprehensive surface drainage AND a minimalist surface finish with ACO RainDrain® Brickslot B 125

*A 10m run could drain up to 145m² paved area during a 50mm per hour rainfall event (in accordance with the guidance in Building Regulations for England 2015 Section H3 2.4).

Both the galvanised and stainless steel Brickslot gratings deliver the same minimalist finish on the surface with their 10mm inlet.

The stainless steel Brickslot grating offers improved performance and delivers a distinct, high-end finish. Check out the photographs of the two products below.

Galvanised and stainless steel products have good corrosion resistance to concrete and mortar products but may experience corrosion if high chloride and sulphate content is present. Use only good quality concrete and consider using corrosion inhibitors where necessary. The use of protective coatings, such as paint, can minimise the risk of corrosion.

To enable maintenance and cleaning, install an access cover at regular intervals in long runs and after any change in direction.

The steel access cover includes an insert tray, into which a section of the surrounding paving is laid. This maintains the minimalist finish of the RainDrain® Brickslot. Access covers are available on sump units and on a 1m length of RainDrain® Channel with a 500mm length of Brickslot grating.

Installing a sump unit at the channel's outlet can help reduce silt and debris entering the stormwater drainage system. 

Two Brickslot Access Cover Lifting Tools (415924) are required to lift the access cover to gain access to the channel.
