Project Description

Do you have a construction project we can help?


Campo Maior, Portugal

The “Centro de Ciencia do Café” museum and exhibition center in Campo Maior, Portugal pertaining to DELTA cafés includes a specially climatized area simulating a coffee plantation. This area is surrounded by a reflecting pool where the waterproofing membrane had failed. The water leaked through the suspended slab which affected a room on the lower level of the building.

Purpose for application

Cafés DELTA had been facing this issue, unable to use the lower room for five years prior to contacting Krystaline. Previous repair attempts had been made with cementitious membranes from the positive side and polyurethane resin injection from the negative side.

Krystaline proposed an integral negative side waterproofing solution. The application included crack, joint and surface treatment for the entirety of the lower part of the suspended slab.

Products applied

Krystaline 1, Krystaline Dry, Krystaline PLUG


All leaks were stopped and the area was completely dry within two weeks. Cafés DELTA recovered the previously unusable space and were very satisfied with the results.
