Silt curtain installation for marine and civil works
Silt curtains are used to help control sediment and turbidity during works in or near waterways. Correct installation is imperative, as curtain performance depends on more than just the curtain itself.
The system must be matched to the site conditions, including:
- water movement
- water depth
- access
- anchoring points
- project duration.
Trade Enviro can supply and install silt curtain systems for temporary or project-based works where sediment containment is required.
Site conditions that affect installation
Before a silt curtain is supplied or installed, the site needs to be assessed so the system can be matched to the conditions.
Key factors include:
| Site factor | Why it matters |
|---|---|
| Water depth | Helps determine the required curtain draft |
| Curtain length | Defines the containment area around the work zone |
| Current or tidal movement | Affects curtain stability and anchoring |
| Wind exposure | Can increase load on the curtain and floats |
| Bed conditions | Influences anchoring method |
| Site access | Determines how the curtain can be delivered and deployed |
| Project duration | Helps determine durability and system suitability |
| Removal requirements | Important for temporary works and project close-out |
Typical silt curtain installation process
The installation process will vary depending on the site, but typically includes:
- Reviewing site conditions and project requirements
- Confirming curtain length, depth and specification
- Planning access, deployment and anchoring
- Supplying the required silt curtain system
- Installing and anchoring the curtain on site
- Checking the curtain position after deployment
- Removing or recovering the system at the end of the works if required
For more complex sites, installation planning is especially important where there is tidal movement, stronger current, deeper water or limited access.
Supply and installation, not hire
Trade Enviro no longer offers silt curtain hire.
Instead, we supply and install silt curtain systems suited to the project conditions. This is often a better option where the curtain needs to be matched to a specific site, installed correctly and managed for the duration of the works.
For temporary projects, we can still assist with a project-based solution by confirming the required curtain type, length, draft depth and installation method before quoting.

- Piling and bridge works
- Jetty and marina construction

Frequently Asked Questions
Do you install silt curtains?
Yes. Trade Enviro supplies and installs silt curtain systems for marine, dredging, civil and shoreline works, subject to site conditions and project requirements.
Do you still hire silt curtains?
No. Trade Enviro no longer offers silt curtain hire. We now focus on supplying and installing suitable silt curtain systems for project-based sediment and turbidity control.
What affects silt curtain installation cost?
Cost depends on curtain length, draft depth, water conditions, anchoring requirements, site access, project duration, transport and whether removal is required.
What information do you need before quoting?
We usually need the site location, required curtain length, water depth, project duration, site access details and any known tidal, current or flow conditions.
Can silt curtains be used for temporary works?
Yes. Silt curtains are commonly used for temporary marine, civil and shoreline works. Trade Enviro can supply and install a system suited to the expected duration and site conditions.
