POINTING

Re pointing your home offers protection against water and damp, aswell as giving tired looking brickwork a new lease of life.

Pointing is the term given to the finish that is between the bricks or stone used to build your house. Depending on the age of the building, the mortar which was used to lay the stone or brick will either be made from lime, or more recently, cement.

The issue of pointing is one which causes irreparable damage to older buildings if done wrongly, and it is important to understand what the mortar joints actually do for the fabric of the house.

The condition of stone walls cannot be viewed in isolation and repointing of any walls will not cure water ingress problems caused by other building failures, such as gutters, roofs, and lead work. These must be in good condition to maintain the life of the walling elements.

Walls need to breathe and if the pointing does not allow this, the wall will rapidly deteriorate. Mortar joints are the lungs of a wall – they allow water within the structure to enter and leave freely. If water tries to leave through stone or brick, it will slowly disintegrate. Block the mortar joints, and the wall will destroy itself.

Mortar should be softer than the material the wall is built with. Pointing should be subservient to the material the wall is built with and assume a secondary role, visually.

At Barwick Roofing we are specialists in the field of re pointing and below is an example of the method we use

• Firstly we will grind out all the beds to a minimum of 18 – 25mm deep
(depending on brickwork)
• Then remove all loose and defective material from the surface area giving us a clean start point.
• We then use a mix of sand and cement mixed with a co polymer solution to give extra flexibility and added weather protection.

The types of brick and stone pointing are vast but our experience means that you can rely on us to advise what would best suit your property.
