I-beams provide midspan support for the garage floor. A header beam spans the door opening at the rear of the building.
The header beam above the door supports one of the I-beams under the garage floor slab.
A second floor support beam sits in the formed foundation pockets.
A worker bolts the steel angle to the perimeter shelf.
The crew sets the steel pans, which are strong enough to walk on but light enough to carry easily.
A welder then spot-welds the pans to the perimeter angle iron.
The pans are also welded to the I-beams.
With steel reinforcing mesh on top of the pans and temporary support walls below, we were ready to place the slab.
Temporary support was provided beneath the pans in preparation for pouring the concrete garage floor.
Chalk lines guide the screeding, leaving the slab slightly sloped for drainage.
A power trowel adds the final finish.
To create a weather lip at the garage doors, the foundation contractor sinks a length of galvanized pipe into the wet concrete, then finishes the sloping apron in front.
To create a weather lip at the garage doors, the foundation contractor sinks a length of galvanized pipe into the wet concrete (A), then finishes the sloping apron in front of it.
The pipe creates a gentle but durable transition from the apron to the floor inside.
