What is Lime Mortar (NHL)?
Lime mortars come in a variety of types and strengths with different suitability in various applications.
One of the most commonly used types of lime mortar today is Natural Hydraulic Lime (NHL), this is a traditional building material made widespread by the Romans and used in historic construction for over 2000 years. Unlike cement, it allows vapour permeability i.e. buildings to “breathe”, preventing moisture build-up and reducing long-term damage.
NHL lime mortars come in a range of strengths ensuring suitability for a variety of applications, from soft interior stone and brickwork to high exposure areas such as chimneys and bridges. It is often even used in sea wall construction and repair for; its ability to set under water as-well as its high strength and durability in harsh marine environments.

When is Lime Mortar Required?
Lime mortar is nearly always the better choice for natural stone, however it is essential for older stone buildings, listed properties, and traditional stone construction where modern cement would cause damage over time.
- Restoration and Repointing of Historic Properties: Designed for solid-walled houses constructed before 1919, this process ensures moisture can escape, effectively preventing serious damp problems.
- Using Soft Masonry: Essential when working with materials vulnerable to harsh cement, such as traditional soft bricks, soft sandstones and limestones.
- Preventing Structural Damage: As a “softer” mortar, it acts as a sacrificial element, absorbing building movement and frost heave rather than forcing the bricks or stone to crack.
- Conservation Areas: Legislation frequently requires or stipulates its use for listed buildings.
- Environmental Considerations: It is more sustainable than cement because it absorbs carbon dioxide and can help meet contemporary sustainable building standards.
- Damp Management: Its high vapor permeability and ability to move moisture to the surface for evaporation make it essential for repairing damp in old buildings.
