EcodurNOx® – Decontaminating additive for earth pavements that purifies the air

EcodurNOx®

EcodurNOx® is a photocatalytic additive that converts earth pavements into active surfaces capable of capturing and neutralizing nitrogen oxides (NOx) present in the air.

It is applied as a surface treatment, anchoring itself in the aggregate and acting with sunlight, continuously improving environmental quality without altering the aesthetics of the road surface.

Advantages of using EcodurNOx® in earth pavements

Active air purification

Reduces nitrogen oxides (NOx) through photocatalysis, continuously improving environmental quality.

Long-lasting effect with sunlight

It operates autonomously every day with UV radiation, without the need for additional maintenance.

Compatible with stabilized pavements

It is easily applied on surfaces treated with Ecodurfix® or Ecodurfixsoil®, without altering their finish.

Where can EcodurNOx® be applied?



✅Park and garden paths


✅Play areas


✅Urbanizations


✅Rural hotels


✅Historic gardens


✅Bike lanes

Structure of an earthen pavement with EcodurNOx® decontaminating effect


The system incorporates a surface layer treated with EcodurNOx®, which activates photocatalysis and neutralizes pollutants such as NOx. It is applied over terracotta pavements stabilized with Ecodurfix®, maintaining their strength, natural aesthetics, and durability.

AGENDA 2030

Ecological and Sustainable Pavements | Commitment to the 2030 Agenda

At Soluciones Ecointeligentes, we are committed to the circular economy to create eco-friendly additives that transform every road into an active player in the fight against climate change. Our new line of sustainable pavement formulations not only reinforces resistance and impermeability, but also captures NOₓ and CO₂ directly from the air, reducing the environmental footprint of construction.


With our state-of-the-art products, you get:


  • Maximum durability: less maintenance and long service life.
  • Superior waterproofing: optimal drainage and weather resistance.
  • Urban decontamination: surfaces that purify the air as you walk over them.
  • Reduced ecological cost: materials designed for lower impact and maximum reusability.

At Smart Eco Solutions, we present EcodurNOx®, the exclusive additive for stabilized natural aggregate capable of neutralizing atmospheric pollutants thanks to photocatalysis and its formulation with nanotechnology.



Boost your project with our nanotechnology additives and position your brand as a leader in green construction, eco-friendly infrastructure, and sustainable urban mobility.
