Stone facades

We carry out the restoration of various stone facades. The main article for the restoration of stone facades is limestone and dolomite, as this building material has been used in Estonia for centuries. In the restoration of stone walls and façades, we carry out repairs to the stone itself as well as to the joints. In the restoration of stone facades, it is important to follow the principle: “The less the restored area differs from the main part of the wall, the closer to the intended purpose the restoration will be.” Both the texture and colour of the stone must be similar when replacing or sealing stone. The same rule applies to the restoration of joints. The colour and type of the repaired joint must not differ from the existing surface.

Maintenance of stone facades

We offer a range of stone façade maintenance solutions. This includes. Water and graffiti protection systems.

Terrasite thatch

In Estonia, terrazzite plaster is a widely used plaster system. Many of the facades of buildings completed in Estonia in the 20th century were built using this method. Aruna-Ehitus OÜ offers the installation of terra cotta plaster for the construction and restoration of new and old buildings.

For the restoration of facades of old buildings, we use terra cotta plaster similar to the original, both in terms of colour and texture. We can carry out both spot repairs and full terracite rendering. We have favoured local render repairs in those parts of the wall where the base render is firmly adhered to the wall, but where there are through cracks due to subsidence. In this case, it does not make sense to dismantle plaster in good condition in order to replace it. The same situation applies to parts of the wall where the plaster has come off locally and a small amount of patching is required. A 100% render installation is necessary in those parts of the façade where the substrate is loose or coming loose. Such areas will be stripped down to the substrate, on which new terra cotta render will then be re-installed as a full solution. The installation of the full render is normally carried out within a specifically defined area e.g. corner to corner, slate to slate, etc. to avoid the old and new render joining.

Choice of plaster

The big challenge is to find a colour and texture similar to the original terracotta. As a rule, it takes us about a month to find a combination of plaster that satisfies the customer and us. So far, we have been able to solve all the challenges related to this issue.

Maintenance of terracotta façades

We carry out maintenance and cleaning work on terrazzite façades. Often, all it takes is a simple cleaning of the terracotta façade to restore the original beauty and shine of the wall surface.
