Laying the Ventilated Stone Base: Creating a Solid Foundation for Your Structure

TLDRLearn how to create a solid foundation for your structure by laying a ventilated stone base. This video guides you through the process of coating the peripheral walls, installing the drain ventilation, and arranging the stones in a calade. It also explains the importance of ventilation and shares insights on environmental impact considerations. Follow along to ensure proper drainage and insulation for your project.

Key insights

⚒️Coating the peripheral walls with earth and lime creates a smooth, sticky mortar for better hold.

🛠️Installing drain ventilation with a perforated tube allows for the exchange of air and reduces excessive humidity.

🧱Arranging stones in a calade or hedgehog formation prevents capillary rise and promotes water vapor exchange.

🌿Using recycled glass granulates as insulation reduces environmental impact and provides anti-capillary properties.

🏗️Proper compaction of the aggregate layer ensures a stable foundation for the structure.

Q&A

Why is coating the peripheral walls important?

—Coating the walls with earth and lime creates a smooth, sticky mortar that improves hold and enhances water vapor exchange.

Why is drain ventilation necessary?

—Drain ventilation with a perforated tube allows for the exchange of air, reduces excessive humidity, and helps evacuate radon gas.

What is a calade or hedgehog formation?

—A calade or hedgehog formation is created by arranging stones on edge, preventing capillary rise and promoting water vapor exchange.

Why choose recycled glass granulates as insulation?

—Recycled glass granulates offer good insulation properties, anti-capillary properties, and a lower environmental impact compared to other materials.

Why is proper compaction important in the aggregate layer?

—Proper compaction ensures a stable foundation by reducing voids and settling, resulting in a more secure structure.
