It was a BAD TIME for this building inspector to show up.

What happens here

Due to the discovery of an inadequate frost footing for the sun porch, the initial plan for a single-tier retaining wall has been modified. In this section, a two-tier retaining wall system will be constructed to provide the necessary frost protection for the existing house foundation. Begin by installing the base course of blocks for the lower tier, ensuring it is perfectly level. Each layer of blocks will then be built upon this base, with geogrid installed at specified intervals behind the blocks to provide reinforcement.

Goal: Build a two-tier retaining wall to ensure frost protection for the house's sun porch foundation.

Tools and materials

  • Compactor Wacker Neuson — Compacting gravel base and backfill layers
  • Excavator Daewoo — Moving gravel for the base and backfill
  • Geogrid — Reinforcing the soil behind the wall blocks
  • Hammer — Adjusting block placement
  • Laser Level Stabila — Ensuring precise leveling of each block course
  • Shovel — Spreading gravel and backfill
  • Gravel — Creating a level base for the blocks and for drainage

where the footing is at all times all right um we excavated our wall out sounds good and um found right here this uh in minnesota here you gotta have frost protection so this is a walk-out basement and the footing goes all the way down here but then steps up right there which means that's right at the ground level so if we were to put our wall where we want to put our wall by backing it up that doesn't give it enough frost protection here so change of plans we have to go back out out into here with our with a with a two-tier wall system in this section just to protect that frost footing all right the block has arrived frost this is going to be a seven foot tall wall so we would have plenty of frost protection we only need four feet but we need frost protection both vertically and horizontally and if we put the wall here and the frost footing is over here and it's not with it's it's too close within that four foot zone we're not going to get frost protection sideways so when we're building a wall we're taking into consideration not just horizontal frost protection or up and down like from the top down but also from the side as well and so to build this wall and to do it right everything has to get moved out [Music] oh don't tip it off ah figure get you on camera make you a little nervous huh if i shut if i shut the camera off is that going to work better yeah it's quite flocking me yeah god we love teasing each other in our company and we've actually toned it down a lot when tim and i first started and we didn't know better we were just two young bucks out building stuff we would make the new guys cry that was part of the initiation process if we couldn't get a new guy to cry like tears we didn't feel like we succeeded and we quickly learned that maybe not the most appropriate thing to do but we sure did have fun learning that that wasn't right alex loves the camera so this is what you're seeing here is what we have to get ready before the inspector can go and if we don't have this done we're not allowed to build up outward we're not allowed to do anything [Music] the weather people are saying that uh supposed to rain heavy this weekend so hope they're right nothing like prepping for rain that doesn't come but at least it's prepped and we get back to work right away on monday so all righty well we actually got a little rain here last night that's uh been a while since we had rain and uh kind of protected what we could out here so we didn't get too…
