self-healing concrete

The UK's first commercial self-healing concrete.

longer lasting concrete.
Self-Healing concrete doesn’t just save you money on maintenance – it adds another layer of protection to reinforcement steel and increases the life-span of structures.

How self-healing bacteria in concrete 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.

the benefits of self-healing

Lower embodied carbon
Reducing the amount of cement and steel in a concrete structure can reduce the amount of CO2 by 72 kg/m3
Greater durability

Seals crack widths up to 0.8mm – removing the need for manual 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

Standards compliant

Meets relevant European and British design codes and is CE Marked. 

what is it for

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

self healing

Reduce the amount of steel reinforcement, increase the lifespan of structures, and reduce maintenance of concrete structures.



Eco-engineering combines biomimicry with self-healing concrete to create nature inclusive structures and coastal defences.



Ultra-durable concrete structures by combining low-carbon concrete with self-healing additive + additional protection to structural steel in with a corrosion inhibitor.

frequently asked questions

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.

The self-healing additive can by purchased direclty from us. If you are loooking for precast products, then head over to the Modular Cubed website. 

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.  

The 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.
