The UK's first commercial bio-based self-healing concrete

Powered by award-winning patented technology, our ultra-durable concrete increases the life span of structures and removes the need for repair.  

How it works

1. Concrete Cracks

It's not unusual to find cracks in reinforced concrete structures. These can be caused when stresses exceed the tensile strength of concrete.

2. Prevent Corrosion

Concrete cracks can result in leakage or corrosion to steel reinforcement. If the cracks are not repaired, it could weaken the structure.

3. Self Healing

When the bacteria inside the self-healing agent comes into contact with water, it multiplies and starts to produce limestone within the area.

4. Cracks Repaired

The limestone fills the crack and seals the damaged area, preventing any further leakage and protecting the steel reinforcement.

What are the benefits?

Lower Embodied Carbon

Uses less cement and steel, can reduce the amount of CO2 by 72kg in the structure.

Greater Durability

Seals crack widths up to 0.8mm, removing the need for repair.

Increased Lifespan

Maintains density of the structure, resulting in up to 30% longer lifespan.

Less Maintenance

Increases water tightness can lead to 30 - 40% less maintenance.

Added Protection

Provides an extra layer of protection to embedded steel reinforcement.

Compliant with Design Standards

Meets relevant European design codes.

Where can it be used?

Our self-healing concrete mix can be used in any concrete structure where exposure to water or moisture poses a risk, including:

Self healing is continuing the story

Lowering the amount of carbon in a concrete product or structure is a step in the right direction, but we can still do more to tackle the effects of climate change.

If we look at other nature based solutions, we can add more value to concrete products. 

Low carbon

Uses less steel and cement, reducing embodied carbon of structures by 50%

Nature based solutions

Offset carbon emissions of structures in urban environments


Adds an extra layer of protection to concrete structures in marine and corrosive environments


Imitates nature's designs to allow concrete to be less intrusive in marine environments

Frequently Asked Questions

What is self-healing concrete made of?

It’s a standard concrete mix with a self-healing agent added to it. The additive contains dormant bacteria which live in the concrete until cracks appear. When the bacteria come into contact with water, it produces limestone and seals cracks.

Where can you buy self-healing concrete?

Head over to JP Concrete for more information on our self-healing concrete mix. 

Who created self-healing concrete?

Self-healing concrete was invented by Henk Jonkers, a microbiologist and professor at Delft University of Technology in the Netherlands. We’re the first to commercially supply this concrete mix in the UK.  

How do you assure quality of the mix?

Our self-healing additive is CE marked globally and protected by numerous patents.

There is an incentive to contractors to use this self-healing additive when you use ultra low carbon concrete or you risk adding repair costs before delivering the product to the end user.
