So does that Trass base just go on top of the native subgrade? What kind of depth is required for freeze thaw stability, or on top of poor soils? I install in a northern climate with terrible soils. (Manitoba Canada.) All clay all the time and freeze thaw out the wazoo…
You would base out the same way you would for a paver base, the bedding layer is simply the trass. Normally we recommend 1.5inches for residential non-vehicular traffic.
Thanks Phil
Thank you, hope you got something out of this.
