Systèmes Sous-sol Québec Q&A

How do I repair my foundation wall that's failing, flipping upwards or sinking inwards from below?

Outside

If you have enough space outside your home, wall anchors are an effective, permanent and economical solution. The system is very simple. Our team digs a hole several feet away from your foundation and installs earth anchor. A steel rod is drilled through a 1 inch hole, thus connecting the wall plate installed inside your home to the earth anchor. Your wall is instantly stabilized and can be tightened over time during dry periods. Foundation Supportworks' GeoLock Wall Anchors are the best on the market for several reasons:

- The installations are made by experienced and certified contractors

- Several sizes are available to adapt to different situations

- All GeoLock anchors are installed with a tip that covers the stem inside the basement

- Hide-A-Way anchor covers conceal anchors to preserve the easthetic of your finished basement, but can be removed during maintenance and tightening.

- Anchors can be installed with support console channels to provide additional reinforcement

Inside

If you have limited access or no outside access is available, some choices are available to you depending on your situation.

Carbon fiber straps are made of a high traction resistance material. They are placed vertically on the wall and are covered with carbon fiber epoxy resistant to sagging. The CarbonArmor wall reinforcement straps are the best.

- They are designed according to the code of the American Institute of Concrete.

- CarbonArmor is incredibly stronger than concrete and 10 times stronger than steel and is designed specifically for the basement.

- The CarbonArmor carbon fibers adhere firmly to the wall. It guarantees coverage and ultimate strength. Whatever the shape of the wall, this product is able to tighten firmly against the wall.

- The unobtrusive design of the CarbonArmor allows for installation in tight spaces as well as behind wall obstructions such as plumbing and electrical conduits, and strips can be concealed by paint and plaster.

- The strategic quantity of the epoxy layer allow us to control the quality of the installation.

The steel beams are installed along the affected height and are then connected to the joists of the wooden floor at the top of the wall and the concrete floor at the bottom. The PowerBrace device has several advantages that set our beam apart from others.

- Our clamping device is patented because it really improves the condition of the wall

- The beam and its components are covered with zinc, which makes the whole device resistant to corrosion, reduces abrasion and erosion and creates a non-toxic surface.

- We install the beams in a professional and non-random manner by properly joining the device to the joists to ensure the integrity of the wood floor joists.

How to install a WaterGuard interior drain system?

The patented WaterGuard interior drain system is engineering specifically for the basement space. Our specialists start by digging a one-foot wide trench on the perimeter of tour basement floor. Then the WaterGuard is carefully set in place and back filled with stones. If a drainage matting is required, it can be installed. A membrane is then installed over the drain and cement is poured to restore your floor. This interior drain sits on top of the footing instead of outside drains that are installed on dirt. This way, it doesn't disrupt the structure of your foundations and it will never clog.

This drainage system has a built in 3/8-inch gap between the floor and the wall to drain wall leaks.

The WaterGuard interior drain is also installed in a way that you can connect your sump pumps and dehumidifier to eject the water away from your house while being able to inspect it every year through the inspection ports. 

Is an interior drain as good as an exterior french drain?

In many cases, an interior drain that is installed on top of the footing is much more effective than an exterior drain for the following reasons:

- The drain is almost never clogged because it is never installed on dirt soil like a French drain.

- It intercepts water coming not only from the accumulation of water around your foundation or from below your floor, but also from wall cracks, something that exterior French drains don't do.

- Our interior footing drain (WaterGuard) comes with a guarantee for the life of the house whereas French drains are guaranteed on average 15 years, and sometimes less than that.

- The interior drain does not require major excavation work such as the French drain, which makes the installation cheaper in many cases. Excavating to install a French drain sometimes requires removing and replacing everything around your home such as balconies, driveways, sidewalks, landscaping, air conditioning units, stairs etc. Then, when the work is done, you would have to put the soil back to fill the trench. 

- It is possible to install an interior drain partially to protect a specific region of the basement, which is not possible with a French drain since you must do the full perimeter for it to work properly.

What is peering and how do steel push piers work?

What is it?

Peering is known as a solution to repair a foundation settlement problem. The supporting (or push) pillars are made of steel and are driven deep in the earth to the bedrock or other stable soil layer. Installed from the inside or outside of your home, these push piers pillars bring the house back to its original position, closing cracks and problems with caulking, doors and windows.

How does it work?

First, our team removes the soil where the pillars will be installed, then heavy-duty steel piers are installed underneath and against the footing of the foundation. Brackets allow steel peer sections to be driven through stable layers of soil. Thus, the peers now support the weight of the house that has been transferred and we can then attempt to move the house back to its original position.

Choosing this option is the least risky if you do not know the soil characteristics on which your home was constructed. It is also a good choice if you plan to move the house back to its original position, restore the value of the property and solve the problem quickly, permanently and with the least possible disruption.

Foundation Supportworks' Push Pier System feature a patented outer sleeve that reinforces the abutment directly below the support, where it is most critical. It prevents twisting, deformation and rotation.

What provokes foundation settlement and what are the indicators?

Settlement is the movement of the house when the ground on which it rests can no longer support it. Soils change; they dry up, shrink up, get wet and soften or the soil is poorly backfilled. Droughts, floods, poor drainage, and house construction are all factors that affect the soil under your house.

To find out if your house's foundations are sagging, here are some clues to look for. 

Outside:

- Stair-step cracking around your bricks

- Chimneys separating away from the rest of your home

- Cracks extending from the corners of doors and windows 

- The separation of a door or a window from its frame or exterior finishing

- Doors and windows out of square

- Caulking recently applied around doors and windows

Inside:

- Cracks in the form of stairs in the concrete wall

- Vertical cracks in a poured concrete wall

- Cracks in your concrete slab

- Crack in the drywall upstairs

To fix this issue, it is imperative to install a solution that will last for the lifetime of the house and that will adapt to the changes of the soil on which your home rests, because the soil will move wheter you like it or not. Our push piers system will solve this issue and will get you the peace of mind you are looking for. 

Why is it important to dehumidify my crawl space?

Air circulates upwards and brings the dam crawl space air to the upper floors. So, if the air is wet and infected with bacteria, you will breathe it.

Here is a non-exhaustive list of the effects of a wet crawl space:

- Mites (allergens)

- Wet carpets that release bad odors

- Condensation, rot, mold in your basement and attic

- Frost or condensation inside the windows

- An increase in heating and air conditioning costs

- A decrease in the life of shingles on your roof

- worsening of allergies and asthma

To solve moisture problems, we offer a complete encapsulation system for the crawl space. We start by fixing water infiltrations, then we isolate the earth and the concrete and insulate the wall with our CleanSpace vapor barrier membrane, we seal the vents and block other air infiltrations and we finish by dehumidifying the air of the crawl space thanks to to our SaniDry Sedona which is specially designed for this environment.
