Slab – Final Inspection Checklist for Home Builder

This checklist ensures slab construction meets quality and code standards, focusing on leveling, finishing, and proper drainage. It also ensures thorough site cleanup and preparation for subsequent construction phases. The checklist is designed to guide home-builders through a comprehensive inspection process, ensuring all aspects of the slab are up to standard before proceeding to the next phase of construction.

Verify the slab is level and plumb with no pits, depressions, or uneven areas exceeding 1/4 inch over 32 inches

Step 1: Set up laser level

Position a laser level at a central point on the slab. Ensure it is calibrated according to the manufacturer's instructions. The laser level will provide a reference line to check the slab's levelness.

Step 2: Measure slab height

Using a measuring rod, take readings at various points across the slab. Compare these readings to ensure they fall within the acceptable range of 1/4 inch over 32 inches.

Step 3: Check for depressions

Walk across the slab and visually inspect for any noticeable dips or depressions. Use a straightedge to confirm any suspected areas.

Step 4: Document findings

Record all measurements and any areas of concern. This documentation will be useful for addressing issues and for future reference.

Ensure the slab surface is trowel-finished and smooth

Pour and broom-finish the garage floor

Step 1: Prepare concrete mix

Ensure the concrete mix is appropriate for a garage floor, with the correct ratio of cement, sand, and aggregate.

Step 2: Pour concrete evenly

Pour the concrete starting from the farthest corner, spreading it evenly across the floor. Use a screed to level the surface.

Step 3: Apply broom finish

Once the concrete has set slightly, use a broom to create a textured finish. Pull the broom across the surface in straight, even strokes.

Step 4: Check slope toward door

Ensure the floor slopes gently toward the garage door to facilitate drainage, adhering to local building codes.

Ensure the garage floor slopes toward the door per code, with no pits, depressions, or uneven areas exceeding 1/4 inch over 32 inches

Pour and broom-finish the patio, stoop, and porch with the correct slope for drainage

Step 1: Prepare the site

Ensure the area is clear of debris and the subgrade is compacted and level.

Step 2: Pour concrete

Pour the concrete evenly, using a screed to level it. Ensure the mix is suitable for outdoor use.

Step 3: Apply broom finish

Once the concrete has set slightly, use a broom to create a non-slip surface. Ensure the texture is consistent across the area.

Step 4: Check slope for drainage

Verify that the surface slopes away from the house, using a level to ensure proper drainage.

Confirm the patio, stoop, and porch are no more than 1-1/2 inches from the house slab

Ensure no exposed aggregate is present in any area

Inspect for cracks or displacement and ensure none are present

Spread excess 57-stone in the driveway cut

Move excess concrete runoff to the driveway cut
