Our customer needed a comprehensive solution for a project that required the construction of an environmentally-friendly structure specifically designed to manage fast moving water from a culvert area, that sees water levels rise substantially during heavy rainfall.
The culvert area had been completely overgrown and required preparatory work of clearing and hardcore/ bed reinstatement. To tackle this, we utilised SoluForm’s underwater and above water 32N bagwork, which includes a biodegradable liner, as the ideal solution. The bagwork was placed below the waterline and secured with specially designed U-shaped rebar pins, allowing water to permeate the liners and hydrate the concrete.
This technique prevents any cement particles from escaping and affecting the river's ecology. Above the water, the 32N bagwork with a water-soluble liner dissolves within 5-10 seconds upon contact with water, offering a quick solution for hand-placed bagwork alongside the underwater bagwork.
Overall, the project was finished in 3 days, using 15 pallets of 5 Pallets of underwater and 10 Pallets of above water bagwork, totalling 45m3. There was no need to completely dewater the area for the installation, as the natural water was used to hydrate the mix of the underwater bagwork and allow the concrete to set.
This enabled an experienced team to hand place the bagwork efficiently and cost-effectively. The solution gave the client confidence in a durable, robust, and environmentally-friendly structure, ensuring the long-term stability of the entire gully. The client and contractor were very pleased with the outcome.
