The Semmelweis University (SU), in downtown Budapest has a medical and educational services
building that was in need of waterproofing repairs. The building is 113 years old and was originally made
of high quality ceramic bricks and mortar without any waterproofing solution. In 2006, water leaks in
the basement rooms were noticed as water was making its way through the thick ceramic brick walls.
Between 2006 and 2007, the building was renovated and contractors used epoxy injections to do the
waterproofing repair, with poor results. The walls have since leaked again and the management of SU
were eager to find a permanent waterproofing solution for the basement clinics.
To provide the long-term waterproofing the SU management wanted they decided to test Kryton’s
Krystol Mortar Admixture (KMA) solution. KMA is a hydrophilic crystalline admixture used to provide
long-term protection of masonry mortars and concrete masonry units against water and waterborne
contaminants by reducing permeability and absorption of the mortar. KMA provides superior
waterproofing performance that lowers building maintenance and repair costs. Once applied to
the negative (inside) side of the wall, the KMA has been able to permanently waterproof the SU
basement walls.
