Rehabilitation of the masonry with the waterproof plaster MineralDicht
Historical waterfront in Tallinn revived

At the historical harbour in the Estonian capital, a line of houses threatened by disintegration has been drained with the 'epasit MineralDichtSperr' system. For decades, during heavy rains the depot complex at the harbour promenade was regularly flooded. In 2011, the Estonian engineering office Langeproon received the order to protect the 19th-century-buildings durably against moisture. After the rehabilitation and renovation, the cozy harbour road developed a busy commercial district.

Tallinn is the economic centre of Estonia, its harbour for centuries an important gate to the Baltic Sea. The originally Soviet stamped cityscape has changed since the Estonian independence and its accession to the EU. Today, Tallinn is an internationally popular destination . The rehabilitation here described is a beautiful example of the symbiosis of Baltic craftsmanship with a first-class rehabilitation system from Germany.

Historical storehouse at the harbour of Tallinn

The complex of buildings at the 'Lootsi' promenade reminds people of the 'good old times' of the commercial port in the second half of the 19th century. It comes from the time between 1870 and 1914 and is called 'Storehouse Girard and Koch' according to the original proprietors, baron Girard de Soucanton and wholesaler Joachim Christian Koch.

Flood damage and countermeasures

The settlement in the historical harbour, however, has a considerable disadvantage: With heavy rains, the total complex of buildings was regularly flooded, the premises and their masonry visibly decayed since the second world war. After the accession to the EU in 2004, the experienced planning office Langeproon got the order in 2011 to protect the buildings durably against these threats. Even though certain proposals have not yet been realized due to cost-related factors, the maintenance of the historical line of houses is guaranteed in the long term.

Rehabilitation step by step

After a drying time of over a month, the wet and loaded old plaster was knocked off at all masonry fronts and the masonry was exposed up to the stone mass. When the foundations were dried up sufficiently, the mason first applied an all-over bonding bridge. Thus, an ideal basis was created for the sealing and waterproof plaster of epasit. Subsequently, it was applied with a thickness of 2 cm and since then it protects the buildings against threatening
floods. The rehabilitation of the masonry was completed by extensive drainage; moreover, the complete area was paved carefully.

From harbour warehouse to commercial district

The old buildings are impressive contemporary witnesses. In the 19th century, they harboured storehouses of the then commercial port. After the rehabilitation, they were renovated comprehensively and rebuilt to bars, coffee houses and business lines. In the heart of the tavern 'Kochi Aidad' (in English: Koch storehouse) a small brewery is accommodated, in which Estonians probably most famous master brewer Enn Kärblane produces one of the best beers by using solid German and Czech equipment. In the small brewery, beer fanciers can participate in a brewing course and receive a certificate of completion. Next door in 'Kochs Coffee Room', guests enjoy fresh baked cakes and pie and call on the wine tavern belonging to it or on one of the many exhibitions in the gallery. So, comfortable room climate developed in the complex of buildings - a perfect completion to the cozy ambience and the pleasurable eating options.
