Why Choose Secil Natural Hydraulic Lime?
 

Secil Natural Hydraulic Lime (NHL) features the same properties it used to have, decades ago, before the introduction of Portland cement. It is an exclusive result of the chemical composition of its natural raw materials.

Our Natural Hydraulic Lime features a unique brownish colour due to the characteristics of the stone that we extract from our quarry, which is the same used since the beginning of the unit’s existence.

Regular tests are carried out in our laboratory to ensure our NHL maintains the same specifications and quality.

Why choose Roundtower Natural Hydraulic Limes?

Manufactured by Secil, the largest producer of Naturally Hydraulic Lime in France, this range of limes gives first-class results, full breathability and vapour permeability, great flexibility, minimal shrinkage and, most importantly, stability over time.

 

This lime is unblended and has been a critical element to the success of thousands of projects throughout Ireland and the world.
