Altes Gerberhaus, Wels (AT)

The listed former Gerberhaus (tannery building) in Wels, Upper Austria, is a particular eye-catcher. On the roof of the building, built in 1925, two imposing tanner figures adorn the front of the building. Due to their exposed location, the representative statues have become in need of refurbishment over the years. Constantly exposed to all weather conditions without any protection, the old coating is already crumbling off and the bare concrete showing through. The waterproofing specialists commissioned by Santech Ges.m.b.H. from Linz perform masterfully both in terms of craftsmanship and logistics. A particularly flexible and easy to apply material was required for the refurbishment work, as the original shape of the figures was to be retained under all circumstances. Therefore, Triflex ProFibre, a fast-setting Triflex waterproofing resin based on polymethyl methacrylate (PMMA).

Refurbishment requirements

  • Flexible and elastic waterproofing of hard-to-reach details
  • Retention of the original shape of the Gerber figures
  • Excellent adhesion to concrete
  • Lasting protection from adverse weather conditions
  • Crack-bridging and impermeable from all sides

Refurbishment steps overview

  1. Thorough grinding off of the old coating
  2. Priming the figures
  3. Waterproofing larger areas such as the base with Triflex ProDetail
  4. Waterproofing all details such as hands, face or muscle parts with Triflex ProFibre

THANKS TO ITS EXCELLENT ADHESION TO CONCRETE, THE LIQUID RESIN HUGS THE FIGURES
LIKE A SECOND SKIN.
