I'm looking for some help and advice. I am building a house and going with superior walls. I have never dealt with them or the building process. I have a couple of questions that I have been unable to find complete answers on. The first one is what does it mean by having the corners pinned. Is that anything more then just marking out the 4 corners after your excavation is done and stone is set before the installation crew shows up? Second part of that is how long should they be and how high should they stick up. I will have frost walls on about half of the walls so do those need to be the same height sticking out as the two that are higher? Second question backfill material and timing for frost panels. Is it best to use stone for the frost panels. Any estimate of how many truck loads of stone may be needed for about 75 linear feet of frost panels 4 foot high? How wide is the trench for the frost panels? Can the material be the same for the interior and external of the panels on the trench. I was doing just drain tile on the exterior ground does not get very wet even during high rain times do I need a sump pump setup? I keep seeing that before backfilling a deck needs to be installed? I am not planning on building a deck at the time of the build will that present an issue. I told the superior wall guy and he hasn't said anything? Thanks for any help.
