Crack repair

Groupe Durasec identifies the causes and suggests effective solutions for the repair of cracks in your foundation.

FOUNDATION
CRACKS

WHAT CAUSES CRACKS IN FOUNDATIONS?

Cracks are sometimes linked to completely natural phenomena. Concrete is not elastic and undergoes shrinkage which can create small cracks that are often harmless. However, you should never ignore foundation cracks, as they can hide more important problems. It is essential to control their evolution and ensure proper foundation crack repairs when needed to avoid water infiltration problems. These repairs are even more essential if your foundation walls are not protected by an effective waterproofing process.

THE OTHER MOST FREQUENT CAUSES OF CRACKING:
  • Movement and swelling of the soil, especially when it is clay-based
  • Uplift of foundations due to freezing
  • Tree roots that are located too close to the foundations
  • Poorly constructed foundations
  • Poor balancing of the weight distribution of the house during construction
  • Problems associated with pyrite in the backfill or concrete foundation walls and floors
  • A physical shock on the house or excavation work carried out in an unsafe manner
WHEN WE DON’T SEE THEM, WHAT ARE THE SIGNS OF POSSIBLE CRACKING?

Apart from visible cracks, there are many symptoms that indicate that your home does not have effective protection against external waterflow. These signs should be taken seriously and addressed immediately, since neglecting them could inflict serious damage on your home and generate significant financial costs.

Groupe Durasec’s specialists can quickly analyze and detect problems in order to carry out rapid and meticulous foundation crack repairs.

THE MOST COMMON SIGNS:

The most common signs are:

  • An excessive degree of ambient humidity in the basement
  • Signs of moisture on the walls
  • Excessive condensation on windows and piping
  • Water accumulation on the floors
  • Musty, mouldy, or bad odours and fumes
  • Softened plaster
  • Crumbling concrete or the formation of salt deposits on concrete surfaces
  • The formation of black spots and mold on walls, fabrics, or woodwork
  • Rotting floors

If you notice that some of these symptoms appear in your basement, you are definitely dealing with the foundation cracking or you don’t have adequate waterproofing of your foundation walls. This is why it is necessary to contact the experts at Groupe Durasec for specialized foundation crack repair services.

TWO SOLUTIONS ARE OFFERED WHEN YOU ARE DEALING WITH FOUNDATION CRACK ISSUES

In order to prevent the problem from arising again, we offer two solutions:

  • Injecting polyurethane foam through the interior of the cracks. This is the least expensive method and the injection is guaranteed for a period of 5 years.
  • Spraying cracks through the exterior, including excavation. We exclusively perform foundation crack repairs by applying RUB-R-WALL. This revolutionary product provides the following advantages:
    • It dries quickly and doesn’t deteriorate over time
    • It’s ecological and doesn’t give off toxic products
    • It can be installed during any season, starting at 4°C
    • It has an incomparable elasticity, even at low temperatures (as low as -26°C)
    • It repairs and stems cracks up to 3.2 mm (1/8 in) wide
    • Any repair carried out this way is guaranteed for 25 years.

 

CONCRETE INJECTION

Injecting concrete is a method to fill a void that occurs with closed formwork. Using a pump, we inject a non-shrink concrete formulation that doesn’t decrease in volume during the curing period.

WINDOW WELLS

If your house has basement windows which open directly to the exterior ground level or lower, they must always be equipped with window wells as well as adequate drainage. Without proper drainage, rainwater can accumulate on the rim and in the window and then infiltrate, damaging everything in its path. Your windows and your foundation walls may undergo serious damage. Frequent moisture can also generate decay and cause spreading of bacteria and fungi that are harmful to your health.

Take action now to avoid serious structural and financial problems.

The Durasec Solution

In order to protect your property and avoid requiring foundation crack repairs, you must:

  • Adjust the levelling and ground level of windows to create clearance
  • Conduct a crushing process and add a drainage system, resting on your French drain (not connected) around the perimeter of the window
  • Install a metal window well or masonry that will isolate the ground from the drainage area and prevent excessive water runoff from your yard to your windows

By carrying out this type of improvement, moisture and water will not stagnate anymore along your windows all while improving their lifespan. Your basement will be protected from all moisture and infiltration coming from this source.

Also, the presence of window wells is necessary for all windows that are too close to the ground. When selling or buying a property, owners who do not have window wells are often required to add them. You might as well install them as soon as possible!

FROST-FREE DOWNWARD-SLOPING
BASEMENT ENTRANCE

Whether you want to build a new downward-sloping basement entrance or replace an existing one that’s feeling the effects of time and freezing, or even build an area away, Groupe Durasec’s techniques are a durable solution.

A downward-sloping basement entrance made with insulated formwork for concrete will allow you not only to obtain a high-quality job, but will also give you a wide range of finishing possibilities that you can do yourself thanks to recycled plastic finishes available in a variety of colours.

DOWNWARD-SLOPING GARAGE
ENTRANCE GUTTERS

Who’s never been confronted with the scary sight of a garage filled with water due to a catch basin that’s too small at the bottom of their downward-sloping garage entrance?

Don’t worry, we have the solution! Whether you have a double or single garage, we will adapt your gutters accordingly. You’ll be protected, even during a downpour.

REBUILDING THE FOUNDATION
WALL FOOTING

It’s possible that during the initial excavation, the depth wasn’t respected, additional material was added to the bottom of the excavation and it didn’t have the bearing capacity to support the weight of the footing and the foundation wall. With a void underneath, the footing can then crack, creating a space between the wall and the footing. It will then be necessary to carry out foundation crack repairs.

It’s also possible that the footing was poured onto frozen ground, causing a similar result. In this situation, the footing sags and cracks when thawing.

In both cases, it’s critical to rectify the situation since the sagging footing will lead to cracking in the foundation walls and rigid sidings, such as brick or stone.
