The hydraulic tile is a type of covering made from a mixture of cement, lime, sand, and natural pigments. It is produced without the use of an oven, meaning that the curing occurs through pressure and humidity (hence the name "hydraulic"). This process allows the tiles to acquire great resistance and durability.
Its main characteristic is the finish, which can be made with geometric patterns, designs, or even images, making it a highly sought-after element to personalize floors and walls, especially in projects such as kitchens, bathrooms, outdoor areas, and commercial spaces.
The hydraulic tile emerged in France around 1850, during the Industrial Revolution, as an alternative to ceramic tile. It was initially used in floors of high-traffic projects, such as shops, cafés, and restaurants, due to its durability, moisture resistance, and ease of maintenance.
The name “hydraulic” comes from the manufacturing process, which uses hydraulic pressure to compact the materials. This ensures that the tile has great resistance, without the need for an oven, making its production more economical.
The hydraulic tile is present in some of the most iconic constructions in Brazil and around the world, being a symbol of elegance and sophistication. In Brazil, for example, it is possible to find examples of hydraulic tiles in various historical constructions, such as the Palácio dos Bandeirantes in São Paulo and the Casa do Bandeirante in Rio de Janeiro. In Rio de Janeiro, the sidewalks are also adorned with traditional hydraulic tiles, a characteristic that dates back to the colonial period.
In other parts of the world, hydraulic tiles can be seen in buildings of great historical relevance, such as the famous restaurant La Coupole in Paris and the Mercado de San Miguel in Madrid. These constructions are landmarks of architecture and demonstrate how hydraulic tiles can be used in a sophisticated and timeless manner.
The manufacture of hydraulic tile is a detailed process that requires skill and manual dexterity. Its production is distinguished by the absence of oven firing, making it a sustainable and artisanal alternative. Below, each step of the process is explained in detail.
The quality of hydraulic tile begins with the selection of materials. Cement, fine sand, marble dust, and natural pigments are used. These components are carefully mixed until a homogeneous paste is formed, ensuring resistance and vibrant colors that do not fade over time.
The design of the tile is defined by metal molds, called "dividers", which create compartments for the colors. The pigments mixed with cement are poured manually into the spaces of the mold, resulting in geometric, floral, or abstract patterns, made with artisanal precision.
After applying the colors, the mold with the mixture is subjected to a high-pressure hydraulic press, around 1200 kgf/cm². This step compacts the materials and ensures the resistance of the tile, without the need for firing in industrial ovens.
The tiles are submerged in water for 24 hours for complete hydration of the cement. Then, they undergo a drying period outdoors of about 28 days, ensuring they reach their maximum resistance naturally and sustainably.
Each piece undergoes manual inspection to ensure the uniformity of designs and colors. Minor adjustments can be made, and a sealant may be applied for greater protection against moisture and stains, keeping the appearance of the tile preserved for longer.
In a world where mass production technologies dominate the market, hydraulic tile stands out for its manual and sustainable production. The artisanal work is fundamental for the quality and authenticity of the product, making it increasingly valued in the construction and decoration market. Furthermore, the manufacturing process without the use of ovens and the choice of natural materials makes hydraulic tiles an ecologically responsible option.
