PROLIMIT PLUS

PROLIMIT+ is a high performance concrete specially designed for pavements subjected to the most adverse conditions, such as freeze-thaw cycles.

It is a variant of PROLIMIT, a concrete that achieves characteristic compressive and residual flexural strengths without the use of single or dual reinforcement. PROLIMIT+ meets the durability needs of pavements subjected to extreme conditions thanks to its provision of structural fibres, in accordance with annex 7 of the CodE “Recommendations for the use of fibre-reinforced concrete”.

Field of application

All types of pavements subject to freeze-thaw cycles, for example:

  • Outdoor pavements.
  • Car park entrances.
  • Footpaths (from 10 cm thick).

Benefits

  • EFFICIENCY: makes it much easier to lay the concrete, as no pumping is expressly required nor the prior assembly of the reinforcement.
  • QUALITY: achieves the required resistance when optimally laid. The provided consistency avoids any on-site addition of water to concrete, plus its ease to work with. The concrete’s residual strength is guaranteed.
  • SAFETY: the elimination of the reinforcement makes it easier to work on safer and more stable surfaces. It also saves on ergonomic positions during the installation of electro-welded mesh.
  • SAVING: faster laying, elimination of the reinforcement, fewer pavement seams and less posterior maintenance.
  • VERSATILITY: multiple finishes that allow for classic concrete paving such as floating or polishing by mechanical means, as well as adaptation to different needs.

Application system

  • PROLIMIT+ is applied in a fluid or liquid consistency and always by specialised Molins teams.
  • Pumpable product.
  • The sub-base must be of excellent quality and fully-compacted to ensure a good base for the concrete.
  • PROLIMIT+ requires admissible external curing for four days, with continuous watering of the entire surface.
  • PROLIMIT+ is applied like conventional concrete. It is chiefly applied by direct pour, although it can also be pumped.
