We supply GeoCurtain™ Class 3 Silt Curtain - Marine Applications - Design-Specific. Send us your quantity and delivery location for a quotation, and ask our team to include installation where your project requires it.

GeoCurtain Class 3 is a floating silt curtain for sediment control during marine construction, ports and harbour works. A suspended skirt forms a barrier that helps limit the spread of disturbed sediment in the water. The curtain, skirt depth and anchoring are configured to the site’s currents, water depth and exposure.

Supply, delivery and installation across Africa

Geosynthetics South Africa undertakes projects through three service options:

Supply only - products supplied to the agreed specification.
Supply and delivery - materials and logistics coordinated to your project site.
Supply, delivery and QA/QC-controlled installation - one coordinated scope from procurement to documented handover.

For projects across Africa, we coordinate with the Geosynthetics Africa Group to mobilise installation crews from group companies across the continent. Materials, delivery, mobilisation and project-specific quality records are agreed as part of the project scope.

Supply, delivery & installation

South African supply

We are the South African supplier of GeoCurtain silt curtains. Ready-stock standard options are available, with project-specific fabrication for the sizes and details your works require.

Delivery & cross-border supply

We supply GeoCurtain silt curtains across South Africa and Southern Africa, including cross-border delivery. We coordinate site access, unloading and cross-border documentation for your order.

How we install

We install GeoCurtain silt curtains. Confirm water depth, currents and the approved mooring layout. Connect curtain sections, flotation and ballast, then deploy and anchor the barrier without leaving gaps. Inspect connections and anchors during the works and monitor turbidity where specified.

Specialist installation supported by Geosynthetics Africa (Pty) Ltd, an IAGI Installer Member.

SELECTION · SPECIFICATION · PROJECT SUPPLY

Choose the right specification

Choose the system around the solids, water conditions, containment duty and available working space.

For dewatering, provide slurry characteristics, flow and required filtrate quality; representative trials may be needed.
For curtains or containment articles, define flow, depth, exposure, geometry and anchorage or filling conditions.
Confirm fabric, dimensions, seams, connections, handling and operating limits for the actual system.

Define the quality records

Retain material and fabrication records, inspect deployment and connections, and agree operating inspections and acceptance criteria.

For a useful quotation: send the grade or performance specification, quantity, location, required date and scope. Availability, delivery and installation responsibilities are confirmed in the quotation.
