Brick pointing, also known as repointing, is a crucial aspect of masonry that involves renewing the external part of mortar joints between brickwork or stone. This process not only enhances the aesthetic appeal of structures but also ensures their structural integrity by preventing moisture penetration and decay. Different types of brick pointing techniques have evolved over time, each with its unique characteristics and applications. In this blog, we’ll delve into various types of brick pointing techniques, their methods, and their suitability for different contexts.
Flush pointing, also known as flat pointing, involves filling mortar joints flush with the surface of the bricks. This technique creates a smooth and uniform appearance, making it suitable for modern buildings with clean lines and contemporary designs. Flush pointing requires precision and attention to detail to achieve a seamless finish.
Weathered or Struck Pointing
Weathered or struck pointing is characterized by slightly recessing the mortar joint from the brick face and creating a sloped profile. This technique provides better protection against water penetration by directing moisture away from the joint. Weathered pointing adds depth and dimension to the brickwork, giving it a classic and timeless look often found in traditional or historical buildings.
Tuck pointing involves using two different colons of mortar to create the illusion of thin joints between bricks. Initially, a base layer of mortar matching the colour of the bricks is applied, followed by a thin strip of a different coloured mortar on top. This technique is commonly used to mimic the appearance of fine joints in expensive brickwork or to refurbish deteriorating mortar joints without completely re-laying the bricks.
Recessed pointing, also known as raked pointing, involves cutting or raking out the old mortar to a certain depth and then refilling the joints with fresh mortar set back from the brick face. This technique exposes more of the brick surface, creating a distinctive shadow effect and highlighting the individual bricks. Recessed pointing is often chosen for its rustic and textured appearance, making it suitable for traditional and rustic-style buildings.
Ribbon pointing involves applying mortar in a thin ribbon-like strip along the mortar joint. This technique is typically used for decorative purposes, adding a subtle accent to the brickwork and emphasizing its vertical or horizontal lines. Ribbon pointing can be combined with other pointing techniques to create custom designs and patterns, adding visual interest to the facade of buildings.
V-joint pointing, as the name suggests, involves shaping the mortar joints into a V-shaped profile. This technique creates a distinct pattern where the mortar slopes inward from the brick faces, forming a subtle groove down the centre of each joint. V-joint pointing adds texture and dimension to brickwork, lending a classic and sophisticated look to the structure. It’s often used in combination with other pointing styles to create visual interest and contrast.
Grapevine pointing, also known as concave or grapevine jointing, is characterized by concave mortar joints that curve inward from the brick faces. This technique resembles the shape of a grapevine or a shallow arch, creating a graceful and elegant appearance. Grapevine pointing is commonly found in historical buildings and architectural styles where intricate detailing is desired. It not only enhances the aesthetic appeal of the brickwork but also provides better protection against water infiltration by directing moisture away from the joints.
What happens if I choice to ignore having my property repointed ?
- Moisture Damage – mortar seals the natural gaps that moisture would normally get through. If this is not treated then over time moisture will find a way through and cause significant damage to interior walls and furthermore, heightens the risk of mold growth which in itself poses health risks.
- Property Valuation – the exterior of a property is the first thing that a purchaser or surveyor sees. Using the right mortar resulting in a high class finish will improve the buildings exterior visual appeal. Having a home which clearly requires repointing in some cases, can decrease your current valuation by up to 10% which in todays average property market equates to a £28,500.00 loss to you.
- Energy Efficiency – because your mortar covers any obvious gaps that wind/air would naturally get through, larger holes and cracks will make a negative difference to your home remaining warmer in the winter months. Long term, this will no doubt have a negative impact on your energy costs.
Clearly over a period, the work involved will increase and therefore overall costs will be more. Coupled with the loss in property valuation, this would result in a total loss of £40,000.00 to the average homeowner so it’s important to…ACT NOW!
