Natural hydraulic lime for green building

The principles of green building involve the use of materials that allow complete environmental protection and eco-compatible development, both as regards their chemical and physical characteristics and the production method.

To find sustainable materials, we looked back to the past, for a return to natural materials, today produced and applied using the latest technologies. One of these is natural hydraulic lime, which produces less carbon dioxide both in the production phase and once applied, as through its second setting process, it reabsorbs this gas from the atmosphere. In addition, it is naturally antibacterial, it is breathable and does not require the use of additives during production. Finally, natural hydraulic lime is ideal for creating thermal insulating plasters and renders for green building.

When natural hydraulic lime is used in green building

Natural hydraulic lime can be used in the preparation of:

Masonry mortar
Natural hydraulic lime external insulation
Lime plasters and renders for interior and exterior building restoration
Grout
Natural hydraulic lime injections
Sealing
Floor screeds
Natural hydraulic lime paints without additives
High-level finishes
Products for consolidating masonry with natural hydraulic lime
Lime and hemp bricks

Natural hydraulic lime: the advantages in green building

01.
Lime, by firing at lower temperatures than cement, produces less carbon dioxide emissions due to combustion and less air pollution.
02.
The production of natural hydraulic lime does not involve the use of additives or other chemical components.
04
The high breathability of lime guarantees healthy and mould-free environments. Indeed, natural hydraulic lime is also suitable for restorations and renovations.
05
Lime is naturally antibacterial.

Lime and hemp in green building

In green building, lime is often used together with hemp, another environmentally-friendly material that was widely utilised in the past, for the construction of plasters and bricks made from NHL lime and hemp. Hemp is grown using little water and no fertilisers, has a CO2 absorption capacity that is four times higher than other plants, is ideal for areas at seismic risk, is a sound-absorbing material as it absorbs vibrations, is biodegradable and reusable. In addition, hemp helps increase the moisture-absorbing and insulating properties of lime. Lime and hemp bricks for green building are therefore a sustainable and effective solution, exploiting the experience of the past for constructing the homes of the future.

Calce dei Berici

Natural hydraulic lime

Calce dei Berici is pure natural hydraulic lime produced exclusively by firing a calcareous marl in running kilns at temperatures below 900°C. Subsequently, the lime is seasoned for an extended period of time to ensure its complete hydration, before being ground and refined with wind separators.
