The Mineralization

The report

One of the first observations we can make concerns the migration of water to the core of the material that can reach the steel reinforcement of concrete constructions and oxidize them. Carbonation will degrade the concretes and will be responsible for exposing their steel reinforcements. In both cases, the swelling of the steel due to rust will cause concrete splinters and weakening of the structure.

Other observations lead us to observe the evolution of materials under the effect of freeze/thaw in some regions of the world. The water in the porosities will swell and cause the material to burst, giving rise to a larger porosity. This new structure of the material will be able to absorb more water, as the porosity is greater, which in turn will have a greater damaging effect by freezing. Thus the flaking, the deterioration of stones or concretes by freezing, is exponential over time.

In other cases, chlorides, associated with pollution particles, will degrade the surfaces of materials and make them friable, powdery, floury.

For more aesthetic considerations, it is advisable to provide protection in cases where, as with paving stones or slabs, the latter are likely to absorb a multitude of liquids (oil, soda, wine, etc.) and dirt (grease, brake pad dust, tyre dust, exhaust soot, etc.) that become embedded in the porosities. A lack of protection often makes it difficult to eliminate tasks.

Finally, mosses and lichens find their happiness in the wet roughness of stones and concretes. Their proliferation also affects the aesthetics and durability of materials.

Better than a film-forming coating, mineralizers penetrate the supports by capillary action, where they crystallize lime and form silica in the porosities. The material is thus waterproofed, consolidated and made more resistant to external aggressions.

The key points

On the contrary of a water repellent treatment based on an organic product will require renewal over time, the mineralization reaction is definitive. The mineralization treatment is to be done only once in the life of the material.

It is like a cold liquid glass that penetrates the materials by capillary action.

The treatment nevertheless allows all kinds of subsequent applications (paints, glue, plaster, etc.),.


Allows the material to breathe. Does not alter the skid resistance. Consolidates the support. Waterproofing and non-film forming.


Easy maintenance. Stops dirt and pollutants from encrusting, not sensitive to abrasion and cleaning products.


Does not release any decomposition products. Naturally absorbed into the structure of the materials. Resistant to UV and chemicals.


The reaction is permanent. Maintains a natural aspect, Increases the life expectancy of the materials.

Cutting edge

New generation of mineralizers, a return to natural and sustainable protection.

The mineralization

Hydro Mineral mineralizers penetrate the supports by capillarity, where they crystallize lime and form silica in the pores. The support is thus waterproofed, consolidated and more resistant to aggression (frost, abrasion, stains etc.).

Invisible to the naked eye, mineralization acts at the heart of the material, here is what we observe under a microscope:







The silica that forms during mineralization at a hardness of 7 on the Mohs scale*1 is the equivalent of quartz.

Mineralizers are solutions of polycrystals of silicon.

They penetrate by capillarity into the supports where they provoke chemical reactions:

The crystallization of free lime

The formation of silica in the pores

Mineralizing increases the cohesion of materials.

It penetrates into the support according to its porosity to an average depth of between 2 and 12 mm.

Mineralizing forms a silica film inside porosities to prevent the penetration of liquid and soil into the heart of materials.

The material remains breathable.
