New build pointing forms an essential part of any construction project. Although much attention goes to the design and construction of a building, the quality of the pointing largely determines the durability and appearance of the facade. In new build projects, it is crucial that the pointing is executed correctly from the start, as this prevents later problems and costly renovations.
In Overijssel and Gelderland, we regularly see new build projects where the pointing does not receive the attention it deserves. This leads to moisture problems, cracks, and accelerated degradation of the facade. In this article, we discuss what is important in new build pointing and what you should pay attention to in order to achieve a durable and aesthetic result.
Why Is Quality So Important in New Build Pointing?
The pointing in a new build project has multiple functions that go beyond just the aesthetic aspect. The joints provide a watertight seal between the bricks, protect the facade against weather influences, and contribute to the structural integrity of the masonry.
When new build pointing is not executed correctly, problems can arise within just a few years. Moisture infiltration is one of the most common consequences of poor pointing. Water penetrating through the joints can cause damage to the insulation, the interior, and even the load-bearing structure of the building. In the regions of Overijssel and Gelderland, where we deal with changing weather conditions and regular rainfall, a watertight facade is essential.
The Right Mortar Choice for New Builds
One of the most important decisions in new build pointing is the choice of mortar. Not every mortar is suitable for every type of masonry, and the wrong choice can lead to serious problems.
Mortar Composition and Strength
The mortar must match the used masonry in terms of strength and composition. A mortar that is too strong can cause the bricks to crack instead of the joints, because the joint is less flexible than the brick itself. This phenomenon regularly occurs in historical buildings that have been pointed with modern, cement-based mortars, but it can also occur in new builds.
For new build pointing, a mortar based on cement, lime, or a combination of these is usually chosen. Lime mortar is breathable and flexible, which is beneficial for the moisture regulation of the facade. Cement mortar is stronger and more weather-resistant, but less flexible. A good pointing specialist will advise on the right composition based on the type of brick, the location of the building, and the climatic conditions.
Color and Finish
In addition to technical properties, aesthetics also play a role. The color of the pointing mortar must harmonize with the facing brick and contribute to the desired appearance. In new build projects, a neutral color is often chosen that supports the architecture without dominating it.
The finish of the joint partly determines the character of the facade. Common joint profiles are the flush joint, the slightly recessed joint, and the profiled joint. Each profile has its own appearance and functional properties regarding water drainage.
Execution: Craftsmanship Makes the Difference
Even with the best materials, the quality of new build pointing depends on professional execution. Pointing is a craft that requires precision and experience.
The Right Moment
Timing is crucial when pointing new builds. The masonry must be sufficiently cured before pointing begins, but it should also not remain unfinished for too long. Weather conditions play an important role in this. In case of frost, extreme heat, or rain, the pointing work must be postponed or protected.
In Overijssel and Gelderland, this means that pointing work is often seasonal. The ideal period is between April and October, when temperatures are mild and the risk of frost is minimal.
Preparation of the Joint
Before applying the new pointing mortar, the joints must be raked out to the correct depth. This is essential for good adhesion and durability. The joint must be raked out to a depth of at least 15 to 20 millimeters, depending on the thickness of the joint and the type of masonry.
After raking out, the joints are thoroughly cleaned and moistened. This prevents the dry bricks from extracting moisture from the new mortar too quickly, which can lead to cracks and reduced strength.
Application and Finishing
The pointing mortar is applied in layers and pressed firmly to achieve optimal adhesion and density. Finishing is done at the right moment, when the mortar has set sufficiently but is still workable. This requires experience and a good feel for the material.
Common Mistakes in New Build Pointing
Despite the availability of good materials and knowledge, we regularly see mistakes in new build pointing in practice. These mistakes can lead to problems that only become visible after a few years.
Mortar That Is Too Strong
As mentioned earlier, using a mortar that is too strong is a common mistake. This often happens from the thought that stronger is better, but this does not apply to pointing. The joint should actually be the weakest link, so that any tensions and movements in the masonry are absorbed by the joint and not by the bricks.
Insufficient Depth
Joints that are applied too shallowly have insufficient adhesion and can easily come loose. This problem often arises due to time pressure or insufficient preparation. In new build pointing, it is important that sufficient time is taken for correct execution.
Neglecting Weather Conditions
Ignoring unfavorable weather conditions is another common mistake. Pointing at temperatures that are too low, during rain, or in bright sun can lead to poor curing and reduced quality. Professional pointing specialists plan their work carefully and adjust it based on the weather forecast.
Maintenance and Lifespan
Correctly executed new build pointing has a long lifespan, but it is not maintenance-free. Regular inspection and timely maintenance significantly extend the lifespan of the pointing.
It is wise to visually inspect the facade annually for cracks, detachment, or other defects. Minor problems can then be resolved immediately before they grow into larger damages. In Overijssel and Gelderland, we advise carrying out a thorough inspection after winter, as frost and thaw place extra stress on the pointing.
With proper maintenance, new build pointing can last 25 to 40 years, depending on the quality of the execution, the materials used, and exposure to weather influences. Buildings on the coast or in wind-sensitive locations generally require a shorter maintenance interval than sheltered buildings.
Collaboration with Professionals
For an optimal result in new build pointing, collaboration with experienced professionals is essential. A specialized pointing company has the knowledge, experience, and equipment to execute the work correctly.
When selecting a pointing specialist, it is wise to pay attention to references, certifications, and experience with similar projects. A good specialist takes the time for a thorough inspection and advice, and works with high-quality materials tailored to the specific project.
In the regions of Overijssel and Gelderland, there are several specialized companies active that focus on new build pointing. It is advisable to request multiple quotes and compare them not only on price but also on the offered quality and guarantees.
Sustainability and Innovation
The pointing sector is constantly developing. New materials and techniques offer possibilities for more sustainable and higher-quality pointing. For example, mortars are now available with improved moisture-regulating properties and a longer lifespan.
Progress is also being made in the field of sustainability. Mortars with a lower cement content or based on alternative binders contribute to a smaller ecological footprint. For new build projects with sustainability ambitions, these are interesting options to consider.
Frequently Asked Questions About New Build Pointing
When should the pointing be executed in new builds?
The pointing is best executed after the masonry has sufficiently cured, usually a few weeks after bricklaying. The ideal period is between April and October, at temperatures between 5 and 25 degrees Celsius and in dry weather. It is important that the masonry does not remain unfinished for too long, as this can lead to pollution and moisture problems.
What does new build pointing cost on average?
The costs for new build pointing vary depending on several factors, such as the surface area, the type of pointing, accessibility, and the chosen materials. On average, the costs are between 30 and 60 euros per square meter. For an accurate price indication, it is advisable to request a customized quote from a specialized pointing company.
How long does it take for new build pointing to fully cure?
The curing time of pointing mortar depends on the type of mortar and the weather conditions. Generally, the mortar is sufficiently cured after a few days to withstand normal loads, but full curing can take several weeks to months. During this period, it is important that the pointing is protected against extreme weather conditions.
Can I do the pointing on my new build myself?
Although it is technically possible to do pointing work yourself, we advise against this for new build projects. Pointing is a profession that requires precision, experience, and knowledge of materials. Mistakes in the pointing can lead to serious and costly problems. For a durable and high-quality result, it is wise to hire a professional pointing specialist.
