Waterproofing Starts

We’re now seeing some very visible progress on the site.  Of course, most of the progress is ‘infrastructure’ and, once completed, will not be seen again.

For example, the rigid insulation (Dow High Load 40), is now neatly in place and ready to be hidden by the waterproofing.

As well, the first waterproofing was completed today.  The sewage ejector will be be at the end of ~50 ft pipe runs so it will be ~5 ft below the rest of the foundation.  The exterior walls of the sewage ejector were formed and then, inside of that, the first waterproofing was completed.

We’re using Grace Preprufe 300R under the mat slab and using Grace Preprufe 160 on the walls.

This photo shows the first waterproofing in place, where the sewage ejector will sit.  They poured the ‘protection slab’ over the waterproofing today, so this is progressing nicely.
