Facade Pointing: Importance, Repair and Moisture Prevention

The mortar joints may be (partially) in poor condition. This poor mortar joint is detrimental to a facade, as excessive water absorption by the bricks can lead to moisture problems in the house. This can also lead to the bricks freezing, for example, and cracking. Poor mortar joints will eventually need to be replaced.

• The old joints must be removed to a depth of at least 1 centimeter before new joints can be applied.
• Good facade pointing is crucial and serves many technical and aesthetic purposes. Good pointing "breathes" and transports and drains water.
• If desired, the facade can be waterproofed after the mortar joints have been repaired. (Waterproofing is the process of making water-repellent.)

If the mortar is in poor condition: this poor mortar is detrimental to the facade, as the bricks absorb too much water, potentially causing moisture problems in the house. This can also cause the bricks to freeze over at some point, for example, due to frost. The poor mortar must be replaced soon.

Damage and/or defects may exist in the cement window . Drainage water from the facade is then more likely to be absorbed by the underlying structure, potentially causing further damage due to freezing, for example. To reduce the risk of moisture problems in the home, these defects in the cement window must be repaired.

The mortar joint of the transom window may be in poor condition. Drainage water from the facade is then more likely to be absorbed by the masonry, potentially causing damage to the masonry due to freezing, for example. To reduce the risk of moisture problems in the home, the mortar joint of the transom window should be replaced.

• Without a trass or cement frame, frost damage can occur in the lower bricks due to rising and freezing moisture.
• If there is water in the stone and it freezes, the stones will break, because the volume of ice is greater than that of water.
