Brick a wall yourself and make it waterproof

There will not be many people who have built the bricks walls of their own house, but building a wall in the garden, the walls for a small gazebo or garden fireplace, is already a lot closer to the possibilities of many DIY -self. In this blog, we look at what has involved in bricklaying a wall, and we also look at what it takes to make that wall suitable for our wet climate. Because even if it is sunny and 20 degrees when you build the wall, not long after rain and wind will hit it with force. How do you ensure that all that moisture does not affect your masonry? We also pay attention to this.

What kind of wall are you going to brick and make water-resistant?

Most brickwork in the Wall format is used in masonry. That is the well-known brick of 21 x 10 x 5 centimeters. Most of the masonry is semi-brick, with the bricks being bricked together in the longitudinal direction and the end result is a wall of 10 cm thickness. Stone bonds are used for thicker walls and freestanding garden walls, where the wall is as thick as the length of the bricks wall. A cavity wall consists of two parallel masonry half-brick walls with space in between. This cavity helps prevent moisture penetration from the outside to the inside and is also often used to apply insulating material.

Foundation for a masonry wall

The quality of your masonry wall stands or falls with the quality of the foundation. A solid foundation must be laid under your brick wall, preferably of concrete. A common rule of thumb is that you need to count one centimeter of concrete foundation for each layer of bricks. The foundation must be at least twice as wide as the wall.

Make masonry yourself

People often talk about cement that is used for masonry, but actually the mortar is meant. Cement is the basic material, which is mixed together with masonry sand and water to form the masonry mortar with which you can brick your brick a wall. The ratio is often 1 part cement and 3 parts sand, but the correct ratio also depends a bit on the application. Depending on whether your masonry job is indoors or outdoors and the type of stone used. By the way, masonry mortar is also available in ready-made bags where you do not have to think about the correct mixing ratio, but only need to add water. It is important that you do not make too much masonry at the same time. The processing time is a maximum of about 2 hours, so do not prepare more masonry mortar than you can process in two hours.

Masonry profiles for straight masonry

Further preparation is important for the quality of your self-masonry wall. In addition to a good foundation of the wall, it is also important to properly align your masonry. You want a straight wall that is level with even joints of about 10 to 12 millimeters between the bricks. You can achieve this by using masonry profiles. These are beams that you place at the ends of the wall to be bricked, and of course, you must ensure that they precisely mark the ends of the wall and are level. By tension a rope between the profiles you can then accurately mark along which line and at what height you have to brick a new row of bricks. That way you can place each new row of bricks straight and level with neat, even joints.

Finishing and waterproofing your brick wall

Once your wall is ready, the masonry should dry and harden for another two weeks. After that, the wall can be grouted. If you then see the beautiful end result of yourself-bricked a wall, you will also wonder how you can keep it so beautiful. Weather and wind can quickly weather your wall, especially if moisture can pull into your wall. And that is unfortunately possible because both bricks and masonry mortar are not naturally waterproof. The material has pores that allow water to penetrate. The effect is that the stones and masonry absorb moisture and dirt. The wall becomes dirty, looks weathered and eventually, the moisture can also penetrate to the inside.

You can make your masonry mortar immediately waterproof by using Cement Mix instead of water when mixing the mortar. You can easily make and keep the entire wall water-repellent by impregnating the wall with Oppercon. This biodegradable hydrophobic agent ensures that no water can penetrate your wall or even breakthrough to the other side. At the same time, the wall continues to ‘breathe’, because the stones are not hermetically sealed and remain vapor-permeable. Thanks to Oppercon’s protection, the wall not only retains moisture but also becomes dirt-resistant. A moisture-resistant and clean result. You can enjoy your brick wall for longer.
