High Quality Construction Materials
PENETRON's construction materials are critical to the strength and sustainability of the hotel complex. PENETRON ADMIX® ensures the tightness and durability of concrete.
This special architectural creation should be able to withstand many problems. They are created in a structure of such volume and complexity in a coastal environment. The hotel complex is located a few meters away from the sea. Reinforced concrete buildings are also part of the design, which even include underground facilities as well as the construction of numerous swimming pools.
The reinforced concrete should not only be completely waterproof, but also protected from the corrosion of its reinforcements. Through the penetration of chlorides, as well as resistant to its carbonation mechanism. For all these reasons, the project engineers decided to permanently and completely seal the concrete, with the addition of PENETRON ADMIX. Special additional concrete with crystal growth, as well as the sealing of the concrete break joints with PENEBAR® SW 55 water-inflatable cords.
The specific project has been certified according to the international LEED standard. LEED (Leadership in Energy & Environmental Design) certification is a green building certification program. From sustainable construction to indoor environmental quality, LEED certification focuses on practices that support human health and the environment in buildings. Green buildings save money, have a positive effect on the health of their users and promote renewable energy sources. They can also improve rental prices to 20% above average and increase sale prices.
The PENETRON materials used are LEED certified
As a first step, PENETRON ADMIX® (crystalline action admixture) was applied for the new concretings, approximately 4000 m3. PENEBAR® SW 55 water-inflatable cords were installed in all construction joints. PENETRON ADMIX® is added to the concrete at the time of its preparation. The concrete is permanently sealed against the penetration of water or other liquids from any direction. It is also protected from wear due to extreme environmental conditions. PENEBAR® SW 55 hydro-inflatable sealing cord, made of controlled swelling hydrophilic butyl is suitable for application in wet or rainy conditions. For its fixing, use the PENEBAR® PRIMER welding primer or a fixing hoop with nails, in conditions of intense humidity.
As a second step, where the concrete needed repairs, it was cleaned and repaired with PENECRETE MORTAR®. Prior to this, the surfaces were primed with PENETRON®, in order to protect the concrete from the influx of seawater. Afterwards, PENETRON® crystalline action spreader was applied over the entire surface, in order to ensure its waterproofing. Also to protect the reinforcement from corrosion due to chlorides. PENETRON® cement-based waterproofing product consists of PORTLAND cement, specially graded quartz sand and various chemicals. They ensure the most effective and permanent sealing of the concrete. PENECRETE MORTAR® is a ready-to-use cementitious mortar that waterproofs, repairs and seals concrete.
Finally, PENETRON GROUT® was applied to fill the gaps between the metal pillars and the bearing plate. PENETRON GROUT® is a controlled-swelling, non-shrinking, non-corrosive, castable cementitious mortar for concrete anchoring and repair.
