Blind Area
Blind Area - Calculate construction and material requirements accurately.
What is a Blind Area?
A "Blind Area" (often called an Apron or Pavement in English, and Отмостка in Russian/European construction) is a waterproof strip of concrete or asphalt that surrounds the perimeter of a building.
Why Do You Need It?
1. Protection: It stops rainwater from soaking into the soil directly next to the foundation, preventing settling and cracks.
2. Insulation: It reduces frost heave in cold climates by keeping the ground drier and warmer.
3. Aesthetics: It provides a clean walking path around the house.
The "Pie" Structure
Base Layers (Bottom to Top)
- Compacted Soil: The native ground must be firm.
- Clay Lock (Optional): A layer of clay to stop water.
- Sand (10-20cm): For drainage and cushioning.
- Gravel (10-20cm): To prevent capillary rise of water.
Top Layer
- Concrete: The most common. 8-15cm thick.
- Reinforcement: Wire mesh (100x100mm) is crucial to prevent cracking.
- Slope: Must slope 3-5% AWAY from the house.
