Waterproofing of "House of Terror" roof in Budapest
Recounting Two Dictatorships
The location of the house could not be better. Unfortunately, its history has been less than peaceful. A museummemorial reflecting on the terrifying decades of both fascist and communist repression throughout Hungary has been erected in the heart of Budapest. The Terror Háza, or the 'House of Terror', is located in Andrássy út, the world-famous boulevard in the Hungarian capital. The name is actually ill-befitting of this grand neo-renaissance building constructed in 1880. But is a reminder of the building's dark past. The house, originally built for a Jewish owner, was used to imprison, torture and murder people from 1937 until the Hungarian Revolution in 1956, after which it became the headquarters of the communist youth organisation. The museum opened in February 2002 and is a memorial to all the victims of two successive dictatorships. The permanent exhibition at the Terror Háza tells the chilling story of the Nazi-affiliated Arrow Cross Movement, which ruled the
country until 1945, and the Stalinist regime after 1945 in Hungary.
The Task - 240 m² Waterproofing
A large black frame, which has the word 'TERROR' cut out of it in large stencil letters, projects from the roof of the corner house and can be well seen from both streets
below. The arrowcross of the Hungarian fascists and a communist star are also visible at the corner where the two streets meet. This roof section was refurbished in
the summer of 2016 using KEMPEROL®, as there were visible signs of water damage at the wall junction. The existing bituminous waterproofing no longer functioned
effectively and the impact of this issue, allied with the penetrating water, meant the lettering was looking the worse for wear. The client was looking for a longterm
waterproofing solution that had already proven itself in harsh and demanding conditions. Enterol, an established contractor with many years' experience of working with
KEMPEROL®, recommended the KEMPEROL® liquidapplied waterproofing system.
The Result - Waterproofing with alpine rope access techniques
After reviewing the costs, it was decided to leave the old roofing system in place. KEMPEROL® offers superb adhesion to weathered bitumen sheeting. Nonetheless,
the substrate must be clean, dry and free from any materials that may hinder adhesion. There was, however, one particular challenge which faced the Enterol specialists
on this project. Working at a height of approximately 20 metres resulted in them utilising alpine-style rope access techniques. Installed safety nets and debris netting ensured the safety of both the public in the street below and the operatives on-site. The liquid waterproofing system was ideal for the intricate geometries of the roof. KEMPEROL® bonds fully with the substrate across the entire surface during the curing phase, creating a homogeneous, seamless surface.
