Finally! I started building my own house. Pt1- foundations and concrete slab

So it begins.. :) Hammering the posts of wall and foundations axes. Marking each post at the same elevation at which the finished ground floor will be. Screwing on the planks at those markings and making sure they are level. Lowering a string to each small surveyor post. These posts mark the corners of foundations and were placed there by licensed surveyor couple of days earlier.. String is then pulled to touch the vertical strings and where it touches the plank, we mark it.. small screws are screwed on to the markings so strings can pe puled between them. We marked the area where the top soil has to be removed. Cca 1m offset from the foundations plus the driveway.. Removing the 20-30cm of top soil. Arrival of the most important table and bench:) Placing a geo-textile membrane. It keeps the different layers from mixing and increases the ground load bearing. A lot of gravel.. Strings are again pulled to mark the foundations. Posts are hammered where the strings intersect. Those are the corners of the foundations. A few post are added in between so it's easier to mark.. Compacting the gravel.. And we start with the foundation dig.. Foundations will sit on 30cm of compacted gravel. The crane came from the other house construction site you can see on this channel. It has 18 meters reach, 1ton load capacity at 10m, 600kg at 18m. Rebar is here.. 5 14mm rods at the bottom, 5 14mm at the top, 2 10mm in the middle, 8mm stirrups every 25cm. Testing the level of compaction with the deflectometer. Placing the vertical rebar anchors for RC posts. Anchors for RC walls. We used 5cm extruded polystyrene for shuttering and insulation of foundations. Wooden stakes keep the shuttering at the right distance and will be removed during the concrete pour. Reinforcing the top part of Polystyrene so the pressure of the concrete doesn't brake it. Tool shack foundations wont be insulated so no polystyrene here.. Concrete is here! First pour of many.. Concrete is C25/30 grade. Vibrating and pulling out the wooden stakes. Removing the wooden reinforcements.. We marked and cut the excess polystyrene to a level plane. This will be the level of the bottom of the slab. We filled the space between the foundations with gravel and compacted it to level 8cm lower. Placing the slab shuttering. Testing the level of compaction again.. Those 8cm height difference is filled with polystyrene. It will insulate the bottom of the slab. Q257 rebar meshes. Here in the left corner you can see water and electricity pipes, unfortunately I didn't have the chance to film how they were placed.. Some concrete blocks to keep the bottom and the top meshes at the distance. Slab pour day.. This slab is 14 cm thick. That's all for this episode, See you next time:)
