Internal & External Use

Natural Hydraulic Lime is a lime based product so should produce less CO2 emissions during production than Portland Cement. We sell NHL as a convenience to our customers, making Ecolime the only web site that you need to visit.

We sell Singleton Birch NHL which is made in the UK and has no cementatious additives unlike NHL imported from Europe. Less transportation means less CO2 and is more sympathetic to restoration work.

Generaly NHL is harder and less kind to stone or brickwork, with a lower porosity and less breathability than Non Hydraulic Lime. However, it has properties that make it the ideal choice for certain applications.

NHL has natural clay content which allows it to set under water - hence the name "Hydraulic Lime". The grading system reflects the active clay content ratios within each of the three materials, NHL2 being the weakest and NHL5 being the hardest product. The 3 grades of NHL are described as Feebly, Moderately & Eminently Hydraulic Limes.

These gradings reflect the diminshed breathability of the finished product.
