Installation Is As Easy As 1-2-3

SABDrain drainage systems uses an M type channel and thus requires the strengthening of concrete to support loads of vertical and horizontal thrust. In creating a concrete haunch to lock the channel, it enables it to meet the required load rating as specified in AS4058 – 2006.

 

SABdrain Tip: To keep grates clear of concrete during installation, flip them upside down in the channel and turn back around once concreting is complete. Or, install a temporary timber grate whilst concreting.
The SABdrain was very convenient to use on the Northern Road Stage 5. The product was easily handled and very quick to install. We used 60% of the allocated time to install the SABdrain than we anticipated.I would recommend the product for use in the future on all our projects

We found the drains suited our purpose perfectly and looked really good when completed. We particularly like the fact that the drain body was strong but lightweight which made our job much easier given the awkward position which the drain was required. Thankyou also for your help with the product specs and the prompt delivery once ordered.

The SABdrain product was used during short construction window where the lightweight product and connection type enabled swift installation to meet our timeframe and mitigate impact to key stakeholders.

The modular design made it very easy to install saving us time and effort we would have otherwise wasted on traditional methods and products as well as allowing us to make minor adjustments to suit on site. Its unique design also allowed the works to become traffic-able far sooner which pleased the community stakeholders. Overall the whole process was simple and we ran into no issues.

Step 1

1. Excavation Design

The size of the trench will need to take into account the dimension and rating of the channel in determining the depth and width of the trench (See Table). The trench should be excavated from the lowest point of discharge to the highest point. The base should be compacted well particularly if the ground is soft.
Step 2

2. Concrete Base

Lay the concrete base to the recommended thickness as specified in table 2.10 using a minimum strength of 20 MPA. Allow enough gradient in the base for water drainage.
Step 3

3. Channel Installation

Assemble the channels including fixing the grates to the channels and position inside the trench starting from the lowest point of discharge ensuring that each channel unit is locked securely together and aligned. Place concrete along the sides of the channel making sure that it worked into the ribbing along the base as well as sides paying particular to the grate support edge.

SAB channels have preset lateral connection for 90 degree joining of 2 channel units together. Allows right angles, corners, tees & crosses without any additional fittings.

Cut out the highlighted section above & join the channels.

Assembly of Grates

Install metal edges if required. Assemble grates & lockdown. Screw and tighten bolts to secure grates and lockdown pieces, ensuring not to tighten screws too much to prevent snapping. Widen anchors to an inclination of 45 degrees from the channel. It is extremely important to concrete with grates inside the channel to prevent bowing. It will be impossible to install grates after concrete has set.

Install Clips

The install clip is designed to support and clip two channels together, ensuring installation is smooth, easy and quick. With a concept of one clip to fit all channels ,this clip design from Italy can be flipped to meet the requirements and sizes from SAB500, SAB600, SAB700 & the SAB900 series.
