Ecological product with a high degree of technological innovation. Mixture of cements, aggregate and 100% recycled polymeric material that confer it higher thermo-acoustic properties to those of the conventional mortar. The pre-support floorings of continuous paving can reach thicknesses of under 35 mm, providing completely levelled and light surfaces without cracks. It is a product that bring acoustic and thermal insulation based on the specifications of the technical building code.

Field of application

  • Surfaces that require higher thermal and acoustic insulation than usual.
  • Surfaces with thicknesses under 3.5 cm.
  • Surfaces for lightweight structures thanks to its low density.
  • As a final layer, PROSILENCE is compatible with floating parquet, marble, terrazzo and ceramics. In the case of ceramics, it is necessary to polish the surface layer.


  • High content in recycled material - Respects the Environment
  • Low density.
  • Better acoustic and thermal insulation.
  • Controlled dosage - Product homogeneity.
  • High planimetry.
  • Ideal and quick placement, high daily performance.
  • Good compressive strength.
  • Optimisation of the space on the site - Maximum cleanness.
  • Safety during application.
  • It provides punctuation to “eco” buildings based on the Technical Building Code.

Application system

It is supplied with a concrete mixer truck on site, and through a pumping system placed by a professional team of applicators that Promsa provides.
