Installation
Install your DEFE flood barrier
Installation instructions for disclosure and front-facing flood barriers
Installation instructions:
The installation process depends on the size, width, and type of DEFE flood barrier you have purchased. Flood barriers longer than 4000 mm (also depending on the height of the wall post) require additional instructions, which can be found at the bottom of the page.
- Ensure that the ground surface is level and that the walls are vertical. If the ground is uneven or soft, a cement sub-base or U-shaped channel is recommended.
- Place the wall post against the desired application location. Using a spirit level, align the post * ensure that they are vertical and parallel. Mark the wall for your reference.
- Cover the back and bottom of the pole with waterproof glue and secure it to the wall. The outer mounting holes must be oriented in the direction of the expected flooding. Press the pole down firmly to ensure the proper sealing pressure.
- Drill into the wall using the inner mounting holes as a guide and insert the wall mounting screws as firmly as possible.
- Create an extra seal around the post using the waterproof glue.
- Insert the draught beam, starting with the bottom draught beam, which can be identified by the thick rubber seal on the underside. The top draught beam is marked with a yellow and black strip and a bolt stop on either side.
- Slide the sliding plate of the pressure system to the top of the post. Tighten with the supplied Allen key and bolt until they sit snugly against the bolt stop.
- Tighten the side bolt firmly into place on the post using the supplied Allen key.
If the wall posts are not properly sheathed, the dam beam will not fit. Ensure that the wall posts are vertical and parallel.
Instructions for flood barriers wider than 4000 mm:
Flood barriers wider than 4000 mm require an additional center point support post, which is included with your order. Every additional 4000 mm of width requires an additional center point support post.
Additional components supplied per 4000 mm:
- Mid-Point Connection Support Station
- Corner support
- Grounded pin
- Pressure system bolt
Additional installation instructions:
- Follow the basic installation process described above.
- Once the sheet pile has been placed, the location where the center support pile must be installed is clear. Mark the location for your reference.
- Align the middle support post and mark the locations of the five support holes, four at the base of the middle support post and one behind the barrier for the attached corner support.
- Drill five holes and secure the earth plugs in them with the waterproof glue. Ensure that the top of the earth rod is flush with the ground level.
- Tighten the support screws to attach the middle support post and the corner bracket.
- Insert the draughts beam, starting with the bottom board, which can be identified by the thick rubber seal on the underside. The top board is marked with a yellow and black strip and a bolt stop on either side.
- Insert the sliding plate of the pressure system into the top of the post and the middle support post. Tighten with the supplied Allen key and bolt.
- Tighten the side bolts firmly into place on the center support post and the side wall post using the supplied Allen key.
