Thank you for posting.

It seems they are moving pretty quickly.

Yeah likely at street level by the end of the year?

Looks like this will be right next door. Wonder how long it will take to build

This topic is currently being discussed in the 'SFU Surrey Expansion' thread.

Oops! Thanks so much!

@clee7903 ~ Just curious the black material lining the floors and the walls is the vapor barrier I presume? I'm just comparing this to other developments and it's interesting to see what people do differently I guess.

Looking pretty close to street level:

I think you're right. I've also noticed all developments have this barrier surrounding the site before concrete are built around it.

If you are referring to the black material applied to the excavation walls (to the shotcrete); it would be a water barrier. The concrete foundation wall would not have a vapour barrier. Vapour barriers typically apply to assemblies which are insulated and you want to control the location where vapour condenses.

OfficeProcrastinator · #**235** Posted **Nov 10, 2016, 6:26 PM**

Hmm interesting I wonder if it's standardized process? From the photos I have of the Polygon: Midori development I don't see them applying any of that material to the excavation walls. From what I could tell it looks like it was applied to the exterior facing portion of the retaining walls ~ where the retaining walls at some portions are spaced about 2-3 feet from the excavation wall.

Marshal · #**236** Posted **Nov 11, 2016, 2:00 AM**

The issue is draining surface water away from the building. For a very long time, and still today, the main method was to apply a coating to the concrete of the exterior foundation face so water could not penetrate and gravity would pull it down to a drainage system at the foundation's base. This is very typical of house-scale construction, but is also done on larger projects.

More modern methods include a membrane applied as discussed above. And also, a physical screen can be applied to the foundation face. These products come in large rolls and include a void space between two physical membranes, the exterior one of which is perforated to allow water in. The void in the 'sandwich' allows the water to fall directly to the bottom. Two things are accomplished: 1) relatively high volumes of water are shed quickly, and 2) water pressure against the foundation concrete is prevented.

These can be used exclusively or in combination. It all depends upon the existing drainage issues (including groundwater) of the site.
