Durallag (Plastic lagging)

[InDepth]

Does anyone have any info on Duralagg (plastic hollow board lagging that gets post grout or aggregate filled) - manufacturer website info? MacNab's Earth Retention Systems Book shows an example, but I'm having a hard time finding any info?.....also with that in mind, does anyone know of plastic lagging board manufacturers?

The bigger question is why would you even want plastic lagging or lagging that needs to be filled? Never saw it, never needed it over a couple thousand jobs.

Agree with PEinc. There is a perception that wood lagging is bad long term, which is a miconception. If the lagging is for longterm (permenant) exposure, either pressure treated can be used or often a concrete face is poured.

More of a curiosity question, since MacNab's Book "Earth Retention Systems Handbook" mentions it as a possible facing. Check pg 201 Fig 5.11 - Dura-Lagg. I could potentially see an argument due to environmental issues (corrosive environments - Skyline HDPE Sheet piling in case)....or even the sustainability issue about using recycled content products.

DRC1, yes agree that pressure treated lumber or a concrete facing can be used for long term.

Have any of you used metal deck as facing? Which manufacturers and what gages?

I talked to Alan MacNab. His business partner retired to Hawaii and had the molds. So it was their product.
