The foundation is the most important part of building your brand new dream home. And well it is also one of the first part of the house that is built.. (no duh right). So this is a crucial part where builders show their true ability and standards.. whether they are wanting to slap up another house or are actually going to build you your quality dream home that you have saved up for, for your whole life. Each picture below represents what we do as a standard unless onditions and engineers state otherwise. The most important part about this is that we take lots of photos during construction and can prove how your home is built. Thats the difference. Do other builders know exactly how its built or just a general idea?
So let’s talk about footings.
In the above picture you’ll see three rows of 15 mm rebar on ‘chairs’. The wire used for the chairs is equivalent to a 10 mm piece of rebar. This is insurance that the rebar is in the middle of the footing. The biggest advantage of these ‘chairs’ is that if you were to lay the rebar flat on the ground.. then you would have to lift them when you pour the concrete which creates the opportunity for error. The rebar holds the concrete in a tensile state.
Code requires footings to be 20 inches what you see here is actually 24 inches wide and 9 inches deep.
Hook Dowels create a monolithic structure. If soil conditions change the footing can separate from the bottom of the wall. Thus keeping the waterproof membrane intact and keeping water out.Here, we have hook dowels just prior to mushroom caps going on. These are 10 mm hook dowels 16 inches apart and their purpose is to tie the footing and the wall together.
Peel & Stick Membrane
This peel and stick membrane wraps down and around the footing providing a water proof membrane preventing water from coming in between your wall and footing. Conventional basements use only a damp proof system which includes tar on top of concrete. The black is weeping tile 4 inches with a ‘sock’. The sock prevents sand from filling up the weeping tile over time. The next step would then be to cover with washed rocks.
The footing wall is one of countless parts in the home building process that we do better.
Thats all for now!
