1 News TECHNOLOGY RAPI-tec innovation Repair and reconstruction of concrete pavements Very fast opening to traffic (3-6 hours) Maximal durability in time. Your internal or external floors have deteriorated and need Fast, Economical and Durable Repair? May 2013 Contact us for an inspection. Our specialists are at your disposal to propose : a personalised proposal for a time-certain and fast applied and re-usable pavement.. Logistic Platforms Freight areas - Deposits - Airports Helicopter platforms - Hangar - Port Areas Parkings - Factories - Shops - Shopping Malls - Aprons - Floors in Concrete, roofs and between levels RAPI-tec Faster, Stronger, Durable, No Shrinkage RAPI-tec aeroslab (screed/concrete) RAPI-tec pav (mortar) RAPI-tec self injection (slurry) RAPI-tec ramp 1 (ramps) RAPI-tec stone (exposed aggregate) Advantages of the RAPI-tec system: - Maximum Efficiency in Technology of Installation without interruption in Commercial and Industrial Activities - Total Package Product Management + Installation - Rapid Execution associated with a rapid hardening and opening to traffic - Resistance, No shrinkage, Durability

2 - Maximal saving in cost en time!!! - Economic advantages on short and long term!!! Which are the RAPI-tec systems? Pre-mix with innovative nano-technology with very high performance belonging to the family of : HPC High Performance Concretes HPFRC High Performance Fibre Reinforced Concretes Almost all the floors have phenomena: superficial or deep damage - Flaking of quartz particles or 'dusting' - cracks after a few months - Contraction Joints Opening and gaping - uncertain coplanarity between the frames... often as consequence the awkward and precarious driving safety for both the driver and the handling and storage of goods. Systems RAPI-tec, Specially Formulated for Rapid Hardening and taking in service in the reconstruction, repair and finishing of concrete floors, allow: Fast Safe Durable Repair - Volumetric Stability with Technology SHRINKO-tec anti-cracking - Quick opening to Pedestrians (1 hours) and the general traffic (3-6 hours) - Maximum wear Resistance - Resistance to shock - Diversification of Functional Solutions, Aesthetic, Colours. RAPI-tec systems allow optimal intervention thickness of 6-10 mm minimum up to 10 cm and more. RAPI-tec aeroslab, for rapid hardening screeds and concretes,allow almost each thickness of application up 40 cm. The correct diagnostic approach on the quality of support, resulting in the proper preparation of the substrate itself and application of RAPI-tec, the prestigious successes have led to: Elimination of Cracks - Total and Partial Elimination of dilatation Joints Restoration of the planarity - no Delaminations - Elimination of dusting - wear reduced by 80% - Excellent Durability.
