How our material behaves

We tell you everything you need to know about polymer concrete, from how it behaves with carbonation, to how pollution and temperature changes affect it.


Why is polymer concrete ideal for use in new builds and restorations?

  • Because it is impermeable and therefore ensures water-tightness.

  • Because it is very resistant and has long durability.

  • Because it is mouldable and therefore all kinds of shapes and sizes can be made.

  • Because it is light and allows better performance on site.


How does polymer concrete behave with carbonation?

  • Polymer concrete does not present the typical carbonation problems in which the internal reinforcements rust and break the concrete, firstly, because it is non-porous concrete and secondly because it is never internally reinforced, as this is not necessary due to its hardness and resistance.


How does pollution affect polymer concrete?

  • Polymer concrete offers very high resistance to chemical products and to different external agents and therefore its physical properties are not affected by pollution.


Can harsh frosts break polymer concrete?

  • No. Polymer concrete is non-porous concrete and therefore does not allow any water to enter that can expand when frozen and eventually burst or break it.


Is the correct installation of polymer concrete complicated?

  • It is not complicated, but we need to take into account several aspects. Polymer concrete is composed of silica aggregates and polyester resins, and therefore has a higher expansion coefficient than traditional building materials. This requires greater care when installing and choosing the bonding materials.


What things must be taken into account for correct installation?

  • Choice of suitable bonding materials. It is recommended to use elastic adhesive mortars to ensure greater grip and absorption of the expansion movement, especially in places where there are large temperature variations.

  • Use of the mechanical anchors provided on the pieces. Polymer concrete prefabricated elements are supplied with mechanical anchors embedded in mortar to be inserted into the adhesive mortar. This guarantees a good grip.

  • Provision of expansion joints. It is essential to provide 5-mm expansion joints to absorb movement between the pieces. The joints will have to be sealed with a suitable material to guarantee the water-tightness of the unit.


What bonding materials should be used for a good installation?

  • The use of elastic adhesive mortars capable of absorbing the movement produced by the expansion-contraction of polymer concrete is recommended.


What is the suitable material for sealing the joints?

  • The use of silicones with a high modulus of elasticity, weather resistance and high stability to UV rays is recommended to prevent yellowing.
