Environmental dredging equipment is specially designed or adapted to remediate waterways that contain contaminated sediments.

Mangroves are trees or shrubs growing in tropical coastal swamps whose strong, tangled roots provide natural protection against waves and storms.

Wetlands are a natural coastal habitat with unique species of flora and fauna that protect against erosion and flooding of nearby communities.

Turbidity is a leading factor in causing underwater disturbances to marine life and must be minimised and monitored during a dredging project.

Sustainability means acting in a way that is not harmful to the planet, preserves natural resources, and thus supports long-term ecological balance.

Underwater sound created by dredging equipment below the water surface can impact marine life and requires careful evaluation and monitoring.

Management Practices for the Environment help maximise both environmental and economic benefits and thus the success of dredging activities.

Flood defence aims to protect low-lying communities close to oceans and rivers from sudden storms and floods.
