Masonry and Concrete Renovation

Façade maintenance

Over the years, masonry joints are affected by weather, the environment or by incorrect detailing on the roof and frontage. The acid elements in rain water flush the adhesive medium from mortar, making it soft and porous. This can cause moisture penetration into the brickwork, resulting in moisture penetration and frost damage. This might mean that the mortar will need to be replaced. Sijtsma Masonry and Concrete Renovation have craftsmen who are specialised in various masonry joints.

• Flush
  The flush joint is used most commonly nowadays, both for maintenance and new properties. This simple joint is called flush, because the front of the joint is equal to the front of the brick.
• Flush brushed/stippled
  To obtain a rougher effect, the flush joint is brushed with a hand brush. An even rougher effect can be obtained by stippling the flush joint.
• Concave
  A concave joint is deeper than the front of the brickwork. This makes the bricks more prominent. The joint can be up to 5 mm deeper than the surface of the bricks.
• Weathered joint
  A weathered joint is a joint that is partially angled away from the brickwork. This causes a shadow to fall on the brickwork. When sunlight hits the brickwork directly, the weathered joint gives the façade a unique appearance.
