Roof waterproofing monument
Project: Waterproofing roof of stronghold Herzele
Our products are used for a wide range of applications, which means that we are involved in many (construction)projects. But it is always a great honor for us to be able to contribute to special projects such as this one.
The stronghold of Herzele was probably built in the 13th or 14th century. The stronghold consisted of a gatehouse, the keep, kitchen, knights’ hall, utilities and the (still standing) round residential tower with attached staircase tower. During the Dutch revolt in 1579, the stronghold was heavily destroyed by the Spaniards and the stronghold has not been fully restored after. Only the gatehouse, the northeast wing (with the residential tower and kitchen), the barn and stables have been restored.
Since 1957, the stronghold of Herzele has been protected monument and restoration works started in 1972, which were completed in 1977. Now, almost 50 years later, it is the roof of the residential tower what needs restoration.
For the conservation and waterproofing of the roof Liquid Rubber has been chosen, partly because of the sustainable solution that it creates. The zinc roof has been roughened beforehand and thoroughly cleaned. All details, joints and seams are first sealed with Liquid Rubber HBS200 and reinforced with the Geotextile. Subsequently, the entire roof was waterproofed by using the two-component spray system. Because our products are applied seamlessly and have excellent adhesion, this great monument is protected yet again!
