Pouring a Concrete Slab for Shed: Step-by-Step Guide

Pouring a concrete slab for a shed requires proper preparation and finishing. Follow these steps: 1. Frame with 2x4s. 2. Compact gravel base. 3. Lay wire mesh. 4. Pour and screed. 5. Edge and broom finish. This guide walks you through each step.

Step 1: Frame with 2x4s

Build forms for your slab:

• Use 2x4s: 2x4 lumber for forms
• Level and square: Ensure forms are level and square
• Stake securely: Stake forms to hold position
• Check dimensions: Verify size matches shed

Step 2: Compact Gravel Base

Prepare the base:

• Add gravel: Place 4-6 inches of gravel
• Compact thoroughly: Use plate compactor
• Level base: Ensure base is level
• Critical step: Proper base prevents settling

Step 3: Lay Wire Mesh

Install reinforcement:

• Place wire mesh: Lay wire mesh on base
• Use chairs: Elevate mesh with chairs (2 inches from bottom)
• Overlap sections: Overlap mesh sections
• Required: Provides reinforcement and prevents cracking

Step 4: Pour and Screed

Place and level concrete:

• Pour concrete: Pour concrete into forms
• Screed level: Use screed board to level
• Remove excess: Screed removes excess concrete
• Establish flatness: Screeding sets the flatness

Step 5: Edge and Broom Finish

Finish the surface:

• Edge first: Round edges with edger tool
• Broom finish: Pull broom across surface for texture
• Finish edges: Complete edging while workable
• Professional appearance: Creates finished, textured surface

The Bottom Line

Pouring a concrete slab for a shed requires: 1. Frame with 2x4s (level, square forms). 2. Compact gravel base (4-6 inches, well-compacted). 3. Lay wire mesh (on chairs, 2 inches from bottom). 4. Pour and screed (level concrete). 5. Edge and broom finish (round edges, texture surface). Follow these steps for a professional-quality shed slab.
