CEMEX is a well-known and respected producer of cement, aggregates and ready-mixed concrete. In addition to standard structural concretes, the company offers unusual PERVIA water-permeable pavements and DECO STONE decorative surfacing concretes.
PERVIA
PERVIA mixtures are a specialized solution for the construction of durable and water-permeable pavements, ensuring the percolation of rainwater without discharging it into storm-water drains.
They allow water to flow freely into the ground, thanks to a specially designed composition and a unique structure of a network of interconnected voids.
Impervious pavements in cities and stormwater drainage systems that discharge rainwater into rivers contribute to inadequate soil hydration. Tight urban development and the reduction of "green" areas means that valuable water resources are irretrievably lost.

ECOLOGICAL SOLUTION
In order to reduce the unfavorable phenomena for the environment, CEMEX has created a modern solution dedicated to urban construction. The PERVIA family of water-permeable concretes are cavernous concretes, also known as drainage concretes. This type of product is characterized by high water permeability to the ground, made possible by a system of air voids. The structure of PERVIA pavement is similar to loosely poured, water-permeable aggregate, yet as strong as standard concrete.

VARIETY OF APPLICATIONS
PERVIA is available in two types. PERVIA classic, used as a sub-base, which provides a water-permeable, even-strength base for paving materials such as polyurethane or concrete pavers, and PERVIA path, used as a water-permeable pavement, allowing to significantly reduce areas of rainwater runoff in urban areas and reduce the amount of rainfall going into storm drains. PERVIA path can be used in the construction of alleys, paths, squares, bicycle paths and bicycle parking spaces, as well as recreational zones and active leisure spaces, as well as in the construction of green roofs and for the substructure of terraces.

POSITIVE IMPACT
Benefits of PERVIA concretes:
- Reducing the adverse effects of heavy rainfall in the city without investing in more efficient sewer networks.
- Relieving the strain on current rainwater channels.
- Prevention of puddles and stagnant water.
- Reducing the negative effects of drought and heavy rains by retaining rainwater in the ground.
- Positive impact on surrounding vegetation due to improved water supply to underground parts.

DECO STONE
DECO STONE are surface concretes with exposed aggregate. They are also sometimes referred to as washed concretes because of the technology used to make them.

UNIQUE PAVEMENTS
DECO STONE can be designed in a wide range of colors and textures. To choose - the color of the concrete matrix - from natural gray to the color obtained through the use of pigments. Another element that determines the appearance is the type and fraction of aggregate - natural fine- or coarse-grained gravels or broken aggregates with a fixed color scheme, such as light gray granites, black basalts or dark Devonian dolomites. The final factor determining the appearance of the pavement is the depth of washout - there are several variations that can be used depending on the fraction of aggregate used.

TECHNICALLY PERFECT
DECO STONE products are pavement concretes of strength class C30/37 and exposure class XF3 or XF4, that is, fully resistant to frost, as well as to de-icing agents.
They do not overgrow greenery and are easy to keep clean. They are made using monolithic technology, that is, they are poured directly on site. Expansion joints are necessary, which can be achieved either by proper planning of working fields or by cutting the expansion joints with a concrete saw. Instead of cut expansion joints, lines can be made from small-size elements, such as stone or pavers.

AVAILABLE DESIGNS
Concrete mixtures on offer from CEMEX include:
-DECO STONE GRAVA with gravel aggregate
-DECO STONE SEMOLA with crushed aggregate
-fine-grained texture up to 8 mm, coarse-grained texture up to 16 mm
