Lime is more than an old building material. 🏛️

It has been part of South Africa’s construction history for generations.

From the Castle of Good Hope to Robben Island, historic structures contain lime-based mortars that help tell us how these buildings were originally constructed.

When heritage buildings need restoration, understanding those original materials matters. It helps guide decisions about how the structure can be repaired while respecting its existing construction.

Why does lime still matter in South African heritage buildings? 🏛️

Old buildings carry more than history. Their walls, mortar and plaster also tell us how they were built.

Lime has been part of traditional construction in South Africa for generations.

Today, it still has an important place in heritage restoration.

Our latest blog looks at South African heritage sites, the role of traditional lime-based materials, and why choosing compatible materials matters when restoring historic buildings.

Why Lime Remains Important in South African Heritage Buildings Discover why lime remains important in South African heritage buildings and how traditional materials can support careful, compatible restoration.

Did you know lime can be used in asphalt? 🛣️

It’s not just used in construction, soil stabilisation and water treatment.

Hydrated lime can help improve the bond between bitumen and aggregate, helping asphalt resist moisture-related damage.

💡 A small but fascinating application of hydrated lime.

Why does lime go into asphalt? 👀

Lime isn't only used in soil, construction and water treatment.

Hydrated lime can also play an important role in asphalt by helping improve adhesion and resistance to moisture-related damage.

Some soils move when moisture changes. 🌧️☀️

Expansive soils can swell when wet and shrink when dry, creating movement beneath roads and structures.

The interesting part? Lime stabilisation can help reduce this volume change in suitable soils by changing the way the soil behaves.

The ground beneath you can move — even when nothing is moving. 🌱

Some soils swell when wet and shrink when dry, creating changes in volume that can cause problems for construction and roads.

So what can lime do about it?

Our latest blog explores the science behind expansive soils, how lime changes clay behaviour, and why proper soil testing matters before stabilisation.

Why Some Soils Swell and Shrink (And How Lime Helps) - Afrilime Some soils expand when wet and shrink when dry. Learn why this happens and how lime can help control soil movement and improve stability.

In mineral processing, getting the pH “close enough” isn't always enough.

A flotation circuit is a carefully controlled chemical environment.

Change the pH, and you can change how minerals and reagents interact. That can influence mineral selectivity and the way the flotation process responds.

So where does lime come in?

Lime can be used to raise and control pH, helping create the alkaline conditions required by certain mineral-processing circuits.

But there's an important part that often gets overlooked:

There isn't a universal “add this much lime” formula.

Ore characteristics, mineralogy, process conditions and water chemistry can all influence lime demand.

That means lime isn't simply an ingredient added to the process.

It's part of the chemistry behind the process.

Swipe through to see why pH control matters in mineral processing — and where lime fits into the picture.

Effective water treatment starts with understanding the water.

pH, hardness and dissolved substances can all influence the treatment process. Water Purification Lime supports key processes such as pH control, hardness reduction and chemical precipitation.

Suitable for a range of industrial, process water, effluent and wastewater treatment applications.

Clear water does not always mean everything is working as it should.

Some of the biggest factors affecting water treatment are things you cannot always see.

pH, hardness, dissolved minerals and suspended solids can all affect how a treatment process performs.

Lime can support pH adjustment, hardness reduction and chemical precipitation in suitable treatment systems. But the right result depends on understanding the water and applying the correct dose.

Water treatment is not only about removing what you can see.

The chemistry of the water matters too.

Factors such as pH, hardness, dissolved substances and suspended solids can all affect how a treatment process performs.

That is where lime can play an important role.

Water Purification Lime can support pH adjustment, hardness reduction and chemical precipitation as part of suitable water treatment processes.
