Nanotechnology, densifying concrete


Nanotechnology is a set of techniques and ways of creating various structures in nano size (0.1 – 100 nanometres), i.e. at the level of individual atoms or particles.


We made use of Nanotechnology in our flooring products, namely: Bautech Formula, Nanoseal® and Nanocoat® densifiers for industrial floors and Terraseal® (also available as Megahard), Terracoat® densifiers for grinded and polished concrete, as well as for decorative polished screeds (terrazzo).


Regular concrete vs densified concrete 


When Bautech Nanotechnology densifiers are applied, molecular structure of the floor is changed, reinforced and tightened. But no additional top layer is created, instead slab's internal structure is modified. This is due to lithium silicate compounds contained in our densifiers. They react with free calcium hydroxide to form hydrated calcium silicates and aluminum silicates (named "C-S-H phases" by professional literature), that provide more stable binding of concrete components.


Thanks to the penetration and hardening of concrete at molecular level, Nanotechnology allows to obtain a highly resistant cement matrix of extreme physical and chemical properties.

Advantages of using silicates of alkali metals:

  • strengthening of the floor surface
  • proper concrete curing
  • perfect penetration
  • better abrasion resistance
  • durability
  • elimination of dust and efflorescence
  • improvement of the condition of old concrete floors
  • small production down times
  • easy maintenance



Bautech Nanotechnology densifiers benefits

While there is little visual concrete's appearance change after Nanotechnology densifier is applied, research proves considerable higher slab's parameters, as shown on below charts.
