Slab – Final Inspection Checklist for Home Builder

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.

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.

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

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

Visually inspect the slab surface for smoothness. Look for any rough patches or tool marks that could affect the finish.

If necessary, use a finishing trowel to smooth out any imperfections. Work in a consistent pattern to maintain an even finish.

Ensure the entire slab has a consistent texture and appearance. Any variations should be addressed immediately.

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

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

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

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

Use a spirit level to check the slope of the garage floor. The slope should be consistent and direct water toward the door.

Walk the floor to identify any low spots that could collect water. Use a straightedge to confirm any suspected areas.

If depressions or incorrect slopes are found, plan for corrective measures such as resurfacing or grinding.

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

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

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

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

Use a tape measure to check the height difference between the house slab and the patio, stoop, and porch.

If the height difference exceeds 1-1/2 inches, plan for adjustments such as adding or removing material.

Record all measurements for future reference and to ensure compliance with design specifications.

Visually inspect the entire slab for any areas where aggregate is exposed.

Use a patching compound to cover any exposed aggregate, ensuring a smooth finish.

Check repaired areas to ensure they blend seamlessly with the surrounding surface.

Walk the slab and visually inspect for any cracks or signs of displacement.

If cracks are found, use a crack gauge to measure their width and determine if they exceed acceptable limits.

If necessary, plan for crack repairs using appropriate methods such as epoxy injection or concrete patching.

Use a wheelbarrow to transport 57-stone to the driveway cut area.

Use a rake to spread the stone evenly across the driveway cut, ensuring a uniform layer.

Use a plate compactor to compact the stone, providing a stable base for the driveway.

Use shovels to collect excess concrete runoff from the slab area.

Transport the collected runoff to the driveway cut using wheelbarrows.

Spread the runoff evenly in the driveway cut, using a rake to level it.
