Preparation
The resurrection of a unique surface preparation method and traditional wall fixing. The timber ‘Dochan’ quickly flattens out any uneven surface for a true, flat, vertical finish that holds together rather than disturbing old lime mortar and loose stone or brickwork.
Mixing
Revolutionary small scale hempcrete mixing process for safe clean material handling making domestic projects accessible and affordable. Measured and consistent mixing with the correct amount of water will prevent drying problem and improve performance.
Casting
The shuttering is secured to the Dochans and the Hemp and Lime is cascaded in. A plasterers ‘Hawk’ makes an ideal guide. Rather than stratifying layers with a flat tamping tool, a sharp stick is used to knit the composite together at the optimum density of 200kg per cubic metre (200 grams per litre).
Results
Temperature and humidity monitoring. Hydrothermal passive heat recovery, no interstitial condensation.
