Silt Barrier Problem
Why does my silt barrier keep tearing at the anchor points?
Question: I have a silt barrier installed and it keeps tearing at the bottom where the anchors are. Can you help? I really don't want to keep repairing or have to buy a new one.
Answer: Thank you for contacting GEI Works with your inquiry. We would be happy to discuss your Silt Barrier problem with you. From the picture that you have sent, the tearing seems to be linked to your anchoring system, since that is where it's occurring. You mentioned that it is tearing at the bottom where the anchors are. This may be the root of the problem.
Anchor Installation with Turbidity Barriers
When anchoring a turbidity barrier, we typically recommend that the anchors be attached to buoys at the top of the turbidity barrier, not at the bottom. The anchors combined with the weight of the ballast chain, plus any sort of current or wave could be putting excessive pressure on the curtain. It is highly likely that this configuration in causing the tearing.
When anchoring the turbidity barriers, anchors should be attached to an anchoring line which is then attached to a buoy. This buoy is then attached to the barrier. This helps to relieve pressure on the barrier, while still keeping the curtain anchored and in place.
Additional Potential Problems
It is also possible that you may be using the incorrect silt curtain type for the water in which it's deployed. If you give us a call and provide us with a few more details, we can provide you with with more information and possible solution.
In general, the each barrier should be used in the following locations:
- Type 1: Calm Water Conditions
- Type 2: Medium Duty/Moving Water Conditions
- Type 3: Rough Water Conditions
If you are using a barrier like the Type 1 in a moving water application, too much pressure will be placed on the curtain and may cause tears or problems with the barrier.
