Concrete VibrationConcrete vibrated as it is poured into the ground beam. Vibrators are necessary to ensure that the concrete doesn't have voids and settles evenly though out the form.

CPAC Quality ControlCPAC Quality Control staff take a sample of poured cement for a compressive strength test. They will let it dry for 2 weeks and then remove the concrete sample from the form. It is taken to a testing center where the stated KSC (Kilograms per Square Centimeter) compressive strength specification of the concrete is tested. A report will be generated.

Floor pour set-upThe prep for the pour of the floor. Note the spacers and wood that will be used to indicate floor depth. The plastic under the rebar frame is the damp course which will seal the floor and ground beam and protect them from ground moisture.

Rebar Floor MeshingThis is a scale shot which shows the 6mm rebar meshing used in the floor pour. Additionally, note the spacer and the piece of rebar that extrudes from the ground beam, which is used to secure the floor mesh in place.

Different Size Crushed StoneNotice the two different sizes of crushed stone aggregate that will be used. The smaller one on the left is used for concrete which will be poured into the large cinderblock holes.

Damp CourseThe damp course is a thin plastic sheet which prevents water penetrating concrete on top of it. This is the look of sub flooring ready for the ready mix concrete floor to be poured. Note the bent pieces of rebar which come out of the ground beam and tie in the rebar to a fixed surface. Also note the depth indicators and spacers.

Ready Mix Pour of the FloorNote the consistency of the concrete. It should have just enough moisture to be able to work it and not be watery.

Footing HoleA footing hole with metal frame work. Each hole was 1 meter square by about 40 cm. deep. In this design there are only two foundation columns in the patio. Throughout the rest of the house there are footing and then a ground beam on top of the footings. The walls are load bearing with columns inside the wall material itself.

Frame SpacerThe use of a spacer with metal tie to keep the metal frame off the surface. The spacer is used to keep the rebar metal frame in the middle of the anticipated concrete pour.

Ground BeamThe ground beam which sits on top of the footings will be 45 centimeters high by 25 centimeters wide. This shows the metal rebar frame work which will be encased in concrete to make the ground beam.

Ground Beam Frame sits on a FootingSince we are using load bearing (heavy) walls, appx. 5.5 pieces of the 12 mm rebar on average cover each section of the ground beam. This shows a T section of the ground beam metal frame sitting on concrete footing.
