MAPEI SOLUTIONS FOR THE PROJECT
Mapei products were involved in the levelling of the stands substrates, the preparation of the substrate in common areas and the technical support for the installation of the stone covering. Mapei proposed a comprehensive approach to create a high-quality surface, in line with the level of the project.
It is important to note that during the construction of the stadium, 486 thousand cubic metres of concrete were used. Since costruction works started 10 years ago some old concrete areas needed repair and Mapei experts proposed MAPEGROUT 430 fine-grained, fibre-reinforced, normal-setting thixotropic mortar for levelling and repairing concrete structures. Thanks to this product it is possible to eliminate any surface defects and fill rigid joints. In the hardened state, MAPEGROUT 430 is a medium strength mortar that has excellent adhesion to steel and concrete, as well as high water resistance.
To eliminate the defects of concrete surfaces, the one-component cementitious mortar MONOFINISH was used. MONOFINISH is characterized by high mechanical strength, provides an ideal grip with all concrete surfaces and forms a durable coating.
In order to prepare the stands substrates for laying the subsequent coating, PRIMER G, a water dispersion primer based on synthetic resins, was used. After drying, it forms a thick film that reduces water absorption of porous substrates and strengthens them. For levelling off the stands substrates, ultra quick-setting, self-levelling very low VOC mortars ULTRAPLAN and ULTRAPLAN ECO were used on an area of respectively 2,500 m2 and 300 m2.
When facing the 400 m2 of the common areas, for the 60x60 cm ural granite slabs the builders chose KERABOND T, a cementitious adhesive without vertical slip, KERACOLOR FF grout and ULTRACOLOR PLUS mortar, both high-quality, cement-based, polymer-modified products with water repellent DropEffect®, which makes joints less prone to dirt collection and more durable.
The arena is now set to be ready and waits for the upcoming sports events: stay tuned with us for the 2018 Football Cup!
