Turbidity or Floating Silt Curtains are flexible sediment control barriers designed to prevent the spread of silt and sediment in lakes, rivers and other water bodies when work is being performed in water, or on or near the shoreline. Constructed of permeable or non-permeable material, the Turbidity Curtain is suspended vertically in the water with flotation material enclosed in the top pocket and a ballast chain enclosed in the lower pocket. Minimal Impact maintains a operating stock standard and custom fabricated sizes with material options and curtain depths and lengths to suit most project needs.
Minimal Impact utilizes multi-segment superflumes. Combined with our water dams we are able to divert up to 5 cubic metres of water per second to assist with open cut river crossings.

Having developed practices and procedures to minimize Harmful Alteration Disruption or Distruction (HADD) of habitat Minimal Impact open cut methodologies have been proven to complete projects on time and on budget with an absolute minimal environmental impact.
Aqua Dam utilizes water filled tubes to control water. Aqua Dam was originally designed as a method for blocking off streams for pipeline crossings. Using Aqua Dams to complete pipeline crossings is one of the most environmentally effective methods in use and is ideally suited to crossings involving large diameter pipelines.
