Foundation Crack Repair
From small cracks to huge foundation issues
A crack in your home’s foundation can represent great harm to the building. The good part is that each type of crack signifies a different kind of problem and it tells you what caused it and what kind of foundation crack repair you need to do. So, let’s see how many types of foundation fissures are there and how can each be mended.
Seeing crumbling or cracked foundations in old Toronto houses is rather common. Though, the same problem can be observed in new buildings due to some construction errors or immense foundation settling.
The materials for foundations can also vary. Cinder block, stone, concrete, rubble, or brick are quite widely used. No matter what kind of material the foundation is made of, our experts will easily fix the issue. We always select the best solutions, right materials, and make the accurate problem identification to repair the crack or other defect in the foundation wall.
Such cracks can be fixed either from the outside part or from the inside one. The interior problems with cracks occur very often when the basement is not completed, for example, when there is no paneling or drywall. In this case, we utilize the epoxy/urethane injection process. It consists of two steps. The first step involves the crack sealing with the epoxy paste from the inside and the other one which deals with the urethane resin injection for filling the crack completely up to its outer soil.
When the problem is a result of the lack of paneling or drywall, the repair is done from the outside part. This process is called wall-clay. We usually core a hole in the ground near the crack and fill it with granular clay. It forms the barrier against the water.
Both processes used for crack repairing are not too invasive and time-consuming. However, they are quite effective. They are usually completed with a life-time warranty that can be ensured to the homeowner or transferred to someone else.
No wonder that the crack in the foundation of your house can cause bigger harm to the whole construction. Since the cracks can be of different types, they can be signs of various kinds of problems. So, it is easy to identify what has led to such a crack. The way of doing the repair can also be chosen due to the nature of the issue. Let us consider different types of foundation problems and how each of them can be fixed.

Foundation Crack Repair Instructions for Each Type of Damage
There are three main types of foundation cracks – horizontal, vertical, and diagonal. However, sometimes, it is difficult to be 100% sure of the fissure nature from the beginning, therefore, you should observe it and see if it increases in size. Experts from Toronto always say that tracking the cracks will help them to conclude how they were developed and plan the best foundation repair procedure.
Horizontal cracks are the most severe type. They can represent serious damage to the foundation and structural integrity of your home. They can be caused by both hydrostatic pressure that can make your basement walls bend and by soil pressure that adds to the problem.
This type of cracks should be repaired immediately and will involve strengthening your foundation as well as a basement leak repair.
These are the most common type of cracks that require the least foundation repair cost. They are the outcome of a foundation settling and can appear even in new houses.
They can be solved with some urethane or epoxy substance injected right into the crack.

The last type is also a very common crack. It forms a 30-75 degree angle diagonal concrete crack and can be seen on both the foundation and basement walls. The reason for this crack can be the position of the house foundation. If a part settles deeper than the rest, you will most likely see this kind of crack.
