Types Of Brickwork Pointing
TYPES OF BRICKWORK POINTING
Types of brickwork pointing in either new or old walls is very important, not only does it make your brickwork look good, but it adds resistance to weather, which will greatly add to the brickworks longevity.
There are quite a few tools employed by bricklayers to achieve the very neat and consistent results that are required to make the brickwork look tidy, consistency of the brickworks joints when building the wall will greatly improve the results and comes with experience. There are 3 main types of pointing that are used today, others are used, but these are normally required when re-pointing existing brickwork on old buildings.
CONCAVE OR BUCKET HANDLE POINTING
Concave pointing or more commonly known as “”bucket handle” is probably the most commonly used in the UK today and is created with a Jointing Iron, which can either be purchased or achieved with an appropriately sized piece of pipe. The mortar should be pushed up to the arris (edge of the brick) with the jointer to create a curved affect, which will allow the water to run off the joint and achieve good resistance to rain.
Weather Struck jointing is a less common technique used today, mainly due to the fact that it is time consuming to achieve and requires a lot of experience the get the required results. When done correctly it will give a lovely aesthetically pleasing look to the wall. A few tools and a lot of patience is required, but will give a great resistance to adverse weather.
RECESSED OR RAKED
Raked pointing is more about looks than actual benefits to the wall in a structural sense. Great emphasise should be given when laying the bricks to full joints, this is needed when raking out the joint with a wheeled raker, so that you do not spend a lot of time filling back in the joints with bits of mortar. With the edge of the brick exposed, consideration should be given when using this method as it will allow water to sit on your brickwork, which will in some areas expose your brickwork to potential frost damage.
Many things will affect the outcome of your pointing, the main problems are:
• Excessive moister in the bricks
• Laying the bricks in the rain
• Very low temperatures when laying
• Very high temperatures when laying
Brickwork pointing will require some experience, but is worth every minute of time taken to get this right, nothing looks worse than badly pointed brickwork.
