The specially designed sand for this project had to be highly tested for PSD (grading), Density, Degradation, Permeability and Sand Castle to ensure that it was better than compliant based on the specifications.
River Sands provided a 2A Filter Sand which was used in the construction of the weighting berm along the main embankment as a filter and to provide additional strength for the dam wall. Our 2A Filter Sand underwent testing prior to the project being awarded, to ensure a better-than-compliant match with the requested specifications.
How we did it
To meet the extensive testing requirements for each batch, ensuring the product was better than compliance with the requested specifications, River Sands performed a number of tests within our on-site ISO 9001 Quality laboratory. We also worked with external laboratories to confirm the results and streamline the sampling and approval process for each batch.
Additionally, we used the space within our sandplant to stockpile approved batches of 2A Filter Sand ready for delivery. River Sands was also able to perform the specialised blending onsite to meet the required specifications.
By using River Sands products, Fulton Hogan was assured of the quality of the sand and its reputation within the industry from other successful projects. Our efficiency within the manufacturing, testing and approval process guaranteed we were within the time constraints of the project timeline. Our team worked closely with the project site management to ensure there was sufficient product throughout the construction timeline, this was greatly assisted by our ability to stockpile approved batches at the sandplant.
As a result of using our 2A Filter Sand, the Sideling Creek Dam upgrades will function for a long period of time.
