C122 Heavy Duty

Place four unfolded and secured C122 metal supports in a 90° arc, approximately 1 m apart. The outermost supports should be at a 90 degree angle to each other.

Begin by connecting the C122 barrier supports using adjustable link bars (ALB). Attach ALBs through keyhole cut on the front beam and slide down to lock. Fix and adapt the ALBs to suitable lengths using their D-clips.

Prepare the corner elements (CE) – hold them up, wide part down. Attach two handles – one in each top hole of the CE, as shown. Fix the handles using their D-clips.

Place two CEs per section onto the ALBs. Slide them down into position ensuring the handles hook onto the ALBs. One to the right and one to the left of each section – leave a gap in between.

Fill the gap by sliding a third CE on top of the other two in the same way.

Start rolling out the membrane from the beginning of the arc. Fold over the top of the barrier between 20 - 25 cm. Fix the position of the membrane to the C122 outer corner section with a sealer clip.

Extend the membrane 9 m out from the C122 outer corner. 

Fold the extended membrane back (1) and seal the folded poly membrane to the barrier with sealer clips (2).

Installed and self-anchored as rising water presses the barriers to the ground.

Place four unfolded and secured C122 barrier supports in a 90° arc, approximately 0.4 m apart. The outermost supports should be at a 90 degree angle to each other.

Begin by connecting the C122 barrier supports using adjustable link bars (ALB). Attach ALBs through keyhole cut on the front beam and slide down to lock. Fix and adapt the ALBs to suitable lengths using their D-clips.

Prepare the corner elements (CE) – hold them up, narrow part down. Attach two handles – one in each top hole of the CE, as shown. Fix the handles using their D-clips.

Place two CEs per section onto the ALBs. Slide them down into position ensuring the handles hook onto the ALBs. One to the right and one to the left of each section – leave a gap in between.

Fill the gap by sliding a third CE on top of the other two in the same way.

Fix the position of the membrane to the C122 inner corner with a sealer clip. Start rolling out the membrane from the beginning of the arc. Fold over the top of the barrier by 20 - 25 cm. Rotate the membrane roll 90° to cover the inner corner.

Secure the membrane with three sealer clips per section – in total 9 clips for the whole corner – along the top edge. Fold the surplus plastic neatly and close the openings using duct tape.

Installed and self-anchored as rising water presses the barriers to the ground.

Hold the wall batten up against the wall in the desired position.

Use a pen to make markings on the wall where the holes in the wall batten are located.

Drill holes in the wall and install suitable anchors.

Unscrew the four tightening knobs and remove the top plate from the wall batten.

Mount the base batten to the pre drilled holes in the wall using screws, washers, nuts and bolts (not included).

Put the top plate and the four tightening knobs back. C122 wall batten installed.

As the barrier line approaches the wall, stop at a distance of a few sections' lengths from the wall. Place the support in line with the barrier, parallel to the wall, as close to it as possible.

Start assembling the barrier from the wall towards the already assembled barrier leading up to the wall.

Patch the section where the two barrier lines meet using adjustable link bars (ALB). Attach ALBs through keyhole cut on the front beam and slide down to lock. Fix and adapt the ALBs to suitable lengths using their D-clips.

Start covering the adjustable section with corner elements. Place them onto the ALB. Slide them down into position (one up, one down) ensuring the handles hook onto the ALBs. More detailed instructions can be found in the "C122 Adjustable section - Setup manual”.

Mount the wall connection pad to the front of the C122 support to bridge the gap to the wall. Align the holes in the pad with the round collared holes on the support and secure with the three armed wing nuts.

Align the bottom part of wall connection pad to the ground. Roll out the membrane over the barrier and secure with two sealer clips per section, along the top edge. Ensure that there is 20 - 25 cm overlap at the back of the barrier.

Continue to cover the barrier. Stop close to the wall. Make a 90 degree turn with the membrane to cover the the wall.

Make sure the membrane covers the wall all the way to the previously attached 122 wall batten.

Give the membrane some slack, leaving a 2-3 cm gap to the wall. Remove the front plate from the 122 wall batten and feed the membrane in – sandwiched between the two plates. Put the front plate back, puncture the membrane and lock with the screws.

Use duct tape to seal the open parts of the membrane. Place the chain on the outer edge of the membrane and wrap it. Secure the embedded chain using cable ties – one every meter. More detailed instructions can be found in the "C122 Straight sections - Setup manual”.

Installed.

Build two approaching C122 barriers in a line. Stop when the distance between the barriers is smaller than one full section 1.2 m.

Patch the section where the two barrier lines meet using adjustable link bars (ALB). Attach ALBs through keyhole cut on the front beam and slide down to lock. Fix and adapt the ALBs to suitable lengths using their D-clips.

Prepare the corner element (CE) – hold it up, narrow part down. Attach two handles – one in each top hole of the CE, as shown. Fix the handles using their D-clips.

Start covering the adjustable section with the CE. Place it onto the ALB. Slide it into position ensuring the handles hook onto the ALBs.

Prepare another (CE) – hold it up, wide part down. Attach two handles – one in each top hole of the CE, as shown. Fix the handles using their D-clips.

Continue covering the adjustable section with the CE. Place it onto the ALB. Slide it down into position ensuring the handles hook onto the ALB. If needed, continue with a third and fourth CE to complete the distance.

Roll out the poly membrane and secure with two sealer clips per section, along the top edge. Ensure that there is 20 - 25 cm overlap at the back of the barrier.

Connect the chain lengths with the karabiners and place them along the outer edge of the poly membrane. Wrap the chain in the membrane – no more than 2 turns. Secure the chain with cable ties, one per meter.

Installed.

Roll out the the previous poly membrane completely.

Start to roll out the new poly membrane in the same direction. The two membranes should overlap with at least 6.5 ft | 2 m.

Continue to roll out the poly membrane. Make sure the overlap stays 6.5 ft | 2m.

Place sealer clips at the top edge of the barrier. Place the chain on the outer edge of the poly membrane and wrap it. Secure the embedded chain using cable ties – one every 3 ft | 1 m. More detailed instructions can be found in the Setup Manual for Straight Sections.

Place a vertical loading chain at the beginning of the new poly membrane to keep it down. Hang it on to the top edge of the barrier using the carabiner.

Installed!

Lift up the ends of both poly membranes approximately 6 in | 15 cm.

Hold the membranes together and align the edges. Seam the membranes by rolling them down.

Continue creating a roll. Make it as tight as possible.

Roll it all the way down to the ground.

Pinch the roll with your fingers. Slide the stapler around it and staple the roll together. Repeat every 4 in | 10 cm along the roll.

Optional: Fold down the stapled roll.

Optional: Tape the roll down to minimize seepage. Tape a second parallel line if necessary.

Done!
