What happens here

Carefully set up the formwork to ensure the concrete slab has an appropriate pitch. The formwork should be pitched away from the house at a slight angle to allow water to drain effectively. If the formwork is not pitched correctly (e.g., flat or pitched towards the house), water will pool on the porch or flow back towards the house, potentially causing damage. Use a level to check and confirm the correct pitch.

Goal: Ensure the concrete porch surface slopes away from the house for effective water drainage.

Tools and materials

  • Formwork Lumber — Creating the mold for the concrete slab
  • Level — Checking the pitch of the formwork
  • Colored Liquid — Demonstrating drainage with and without pitch

What they say

Hide

sheathing. Pull back your house wrap and add a flashing. Install counter flashing. Now when we get water, the water will hit the flashing and your sheathing will stay dry. If this formwork doesn't get pitched away from the house, water will flow back towards your house. Pitch it away from the house, water will run away from your house. If we set our formwork too low, your concrete will be thin and weak. If we attach our formwork with nails, these forms will be hard to pull. If
