Terrazzo – Cast-in-situ Synthetic Resin Mosaic Stone

Terrazzo – Cast-in-situ Synthetic Resin Mosaic Stone

Because of its water-permeable, non-slip design and resistance to heavy pedestrian and light vehicle traffic, it is a beautiful floor covering that may be utilized both indoors and outdoors, such as walkways, parking lots, poolsides, squares, and parking lots.

It’s made by combining natural aggregate and synthetic resin at a thickness of 2mm to 4mm, then spreading it over the ground (minimum 8mm). The many color options allow for patterning.

The production of white cast-in-place synthetic resin flooring that adheres to the outside with a natural aggregate combination begins with the mixing of binder, hardener, and aggregate shards with appropriate properties. It’s then molded by pouring and pressing 8mm thick on footpaths or bicycle routes.

Ground Conditions

  1. Before the application, the following operations should be carried out by the administration on the floor to be applied, and the floor should be delivered to the contractor.
  2. The C25-C30 steel mesh reinforced concrete/screed of the floor must have completed a minimum of 21 days of curing. If a screed is to be made, the screed should preferably be reinforced on a reinforced concrete floor, with a minimum of 350 doses, and if possible, fiber reinforced, at least 5 cm. Otherwise, the contractor cannot start work until the necessary conditions are met.
  3. Plumbing and electrical work that must be left on the ground and completed must be completed.
  4. The floor should be delivered with a level difference of +/-3mm and with a polished finish.
  5. There should be no oil and derivative stains, cracks, crusts, and weak layers on the floor. It should be delivered after cleaning and corrections, if any.
  6. The floor is delivered/received with the “Site Delivery Minute”, which includes the above items, to be issued jointly by the administration representative and the contractor site authority.
  7. If the ground conditions are not met, a report is taken from the administration and the application is not covered by the warranty.


  • Joint laths are made with 2 mm thick aluminum profiles. Joint laths are mechanically mounted on the floor in such a way that there are no gaps that may cause chemical leakage from under the lath.
  • After the floor to be applied is cleaned of dust and dirt, epoxy polyurethane-based primer (200gr/m2) is applied to the floor.
  • Aggregate shards are mixed homogeneously with the binder + hardener resin and 5% mechanical mixers.
  • The prepared mixture is poured at the desired level based on the elevations of the joint laths that have been prepared before, and the floor is leveled after being compacted with a trowel.
  • It should be waited for as long as the curing time suggested by the contractor, ensuring that there is no pedestrian, bicycle, and vehicle traffic on it and there is no contact from anywhere. This period is between 12 hours and 24 hours depending on the weather conditions.
