settleing of quick 4 chambers

[hockeyologist]

Has any one had any problems of shifting over a period of time and silt being washed into the trench bottom through the louvers on sides of chambers . We've tried putting a small amount of gravel under chambers , this helps some , soil type is sandy loam. System installed at 24" max depth. Back fill native soil.

Here's a couple of ideas.....

1. Did you install the chambers in a pre-existing field that may not be percolating well?

2. Is there a low spot in the ground just above the chambers that would puddle water in a heavy rain and saturate the field?

3. Did you apply any landscape cloth over the louvers to prevent mud form getting back into the chambers?

4. Did you drive rebar stakes around the chambers to prevent shifting?
