Since the beginning of times, clay has played an important role in human history. Clay has been used for finishing buildings and dwellings already for millennia.
Clay as an interior construction material is beneficial for the health of both the wall build-up as well as inhabitants. Nowadays, a smart choice of materials may be more relevant than ever before, with clay having the smallest ecological footprint and being the most sustainable building material on the Earth. UKU raw clay products are pure, consist of none but natural ingredients, are antistatic and can greatly contribute to a healthy indoor climate in your premises. In a room with clay plastered walls, you can be in direct contact with nature and feel the ancient wisdom of the world's oldest building method. Working with clay is a pleasant and natural process – the mixtures are easy to mix and apply. One may even find working with clay plasters and paints therapeutic (there is a risk that all the family members may wish to partake in the working process).
Our plaster mixtures are 100% natural and with the widest range of tones in Estonia. To achieve the right tone of the clay products, we only use pure natural clays of different colour and vast majority of them are local – from within a radius of a few hundred kilometres from the production site. The manufacturing process is no less important, for production we use 100% renewable energy coming directly from solar panels installed on the roof of our production building.
Over time, we have always stood for preservation of clay houses and protecting the clay building heritage and this is why we have developed different special mortars for renovation/restauration of old clay buildings, also light-clay and massive clay mortars. Our product line provides both CEB (compressed earth blocks) and lightweight blocks for various applications; as well as clay mortar for masonry heaters.
The quality of UKU clay plasters has been assessed to be compliant to the German standard of factory-made earth plasters and accordingly, the base, finish and fine finish clays in our product line are exclusively of the highest strength class.
