Mortar is a building material consisting of sand, binder and water. It connects bricks and is used for plastering ceilings and walls. Mortar can also contain additives and agents such as short fibres.

Mortar types by function:
Masonry mortar, plaster mortar, fire protection mortar, synthetic resin mortar, joint mortar, screed mortar, grouting mortar, swelling mortar, injection mortar, levelling compound mortar, water mortar, repair mortar, injection mortar

Function of the fibre:
Moisture regulation
The fibres reinforce the level of protection against penetrating moisture.

Weather protection
Fibres have to be added to the mortar matrix to offer protection from storms, heavy rain and heat, . Fibres are used to make the mortar more resistant and to avoid stress cracks due to varying temperatures (direct sunlight).

Mechanical resistance
Technical fibres are mainly used in masonry and injection mortar to improve their mechanical properties.
The tensile strength and rigidity of the mortar matrix is significantly improved by adding short fibres.

Flexibility
The masonry mortar is very elastic. This is beneficial because it compensates for stresses in the masonry. The fibres that are used are responsible for the flexibility and elasticity of the mortar.
