Pacific Fertiliser provides products for large dam and batter construction works.
For over a decade we have been supplying gypsum and bentonite and other products for dam construction projects in NSW & QLD. In some areas we are also spreading products before they are incorporated into the soil for stabilisation and other desired outcomes such as dam sealing and rehabilitation.
Below is a very general example of how gypsum can be used used during dam construction to stabilise the soil to be used in the dam wall.
Firstly the soil material to be treated before use in the dam wall construction, is placed on a pad via scrappers to a depth of 300mm. Then our bulk gypsum is spread over the soil at a calculated application rate (a general app rate to stabilise soil over the numerous dam projects has been approx 2-3% w/w gypsum per cubic meter of soil).
Once the gypsum is spread over the pad, the client uses large pulverisers to incorporate and blend the gypsum with the soil down to 300mm. Once blended, the soil mix is removed by scrapers to place it in the desired location for the construction of the dam walls and batters.
Pacific Fertiliser has worked on stabilisation projects throughout NSW and QLD for both civil and mining industries on dam, batter, rail and road works.
Note: this is a general example. Gypsum application rates are determined using civil engineers and tested of the actual soil to be used in the wall construction. Gypsum application methods will also change depending on available space and equipment.
