Discover a very flexible waterproofing mortar
Bigum is a
highly waterproof and flexible cementitious mortar.
It is used for the construction of waterproof coatings such as terraces, swimming pools, balconies and all environments subjected to the deteriorating action of water, before applying the tiles.
It is also suitable for the protection of concrete and masonry structures.
It is easy to prepare, as it only requires mixing with water.
Examples of waterproofing mortar applications:
- Waterproofing of concrete tanks for water containment;
- Waterproofing of bathrooms, showers, balconies, swimming pools before laying ceramic coverings;
- Waterproofing of plasterboard, plaster or cementitious surfaces and lightened concrete blocks;
- Smoothing of concrete structures;
- Protection from water and aggressive agents of plaster and concrete with cracks;
- Waterproofing of concrete surfaces that can come into contact with sea water.
The adhesion of Bigum is excellent on all concrete, masonry, ceramic and marble surfaces as long as they have been perfectly clean.

Preparation of waterproofing mortar
Pour 16 to 20% clean water into the powder mixture. Add the water gradually, under very slow stirring with a drill (max 500 rpm), until a homogeneous and lump-free mortar is obtained.
15 kg package: add 2.5 to 3 kg of water to obtain a more or less fluid mortar.
Waterproofing mortar consumption
About 1.5 Kg / m2 for a thickness of 1 mm per coat. Two coats are recommended. Do not exceed two millimeters in thickness.
Support for applying waterproofing cement mortar
The floors to be covered must be roughened and have an excellent basic cleaning.
For waterproofing concrete surfaces: remove any traces of dust and grease by washing with water under pressure, it is preferable that the surfaces to be treated and cleaned are first moistened with water.
To waterproof control joints, horizontal and vertical connections, use a rubberized tape with felt. Apply a thin layer of Bigum of at least 1 mm on the sides of the edges and expansion joints to be waterproofed. Dip the fabric part of the tape onto the still fresh Bigum layer using a spatula. In the case of joints (e.g. in terraces) the belt must be positioned in their seat so as to form an omega.
