Frequently Asked Questions

Why should I fix this problem?

How serious is my water problem?

The water that is not escaping through the foundation wall is the source of trouble. This water will cause lower wall deterioration, cracks or bulges in the walls, and many other concerns. A thorough inspection by a trained professional is needed to determine the extent or severity of the problem.

Why does my basement leak?

1. Hydrostatic pressure — water penetration up from below your basement floor. This is the result of the groundwater table rising upward.

2. Lateral pressure — water penetration through your foundation walls. This can result from water movement through natural underground veins, from poor ground drainage or downspouts that empty too close to your foundation, or from water simply building up in the hole in which your house sits.

How is water getting under my house?

How does it work in the summer and winter?

What about energy factors – expelling air conditioned air in the summer or heated air in the winter?

What is Humidex?

Humidex focuses in on the major source of moisture problems which is the lowest point in a house where there is the most moisture infiltration, stagnation and condensation; namely the basement and crawl space. The unit entirely expels the cool damp air out of the house and uses the warmer and fresher upstairs air to effectively lower relative humidity and dry out the structure.

It creates an air exchange in the entire house that will reduce moisture related problems such as excess humidity, a musty basement , mildew, and alleviate conditions that aggravate asthma and allergi.

Why Exterior Waterproofing?

Water concealed below grade can get under the footings in a foundation, and destabilize the structural integrity of your home or business. This can lead to cracked foundation walls and footings, and very costly repairs.

Standing water and heavy moisture can lead to an infestation of mould, mildew and fungus on the joists, studs and sheetrock in the basement, not only can mould lead to wood-rot and costly repairs, it can be quite damaging to your health. A.C.C.L Waterproofing certified mould remediators will remove the mould spores, mildew, fungus, toxins and dead organic material from all surfaces, apply a superior mould-resistant coating, and install a moisture control unit to prevent any recurrent mould growth in the future.

Exterior waterproofing will prevent any water from damaging your home and save you thousands of dollars in the long run. Homeowners should use common sense when hiring a contractor to do exterior waterproofing. Safety must play an important role in this process. Improper excavation and backfill can lead to personal and/or structural damage. Contractors should be licensed, insured and follow Ontario Building Code and local regulations regarding excavation.

Looking for “Hidden Mould”?

How do I fix a mould problem?

If you clean up the mould, but don’t fix the water problem, then, most likely, the mould problem will come back. Mould remediation should only be performed by an experienced contractor who understands the danger of the process. Improper containment areas and removal can result in a cross-contaminated structure with a more widespread problem than existed before the work began.

What is the cost?

At A.C.C.L Waterproofing Systems, our prices are always competitive with our reputable competitors, and cheaper than many. One thing is certain: your cost will be a lot less than the increased value in your home that comes with the A.C.C.L Waterproofing Systems Lifetime Warranty.

Can we ever finish our basement with confidence that it will stay dry?

Will insurance cover the cost of the repairs that I need?

Should the previous owner have to pay for fixing the problems that I have?

What about clay (sodium bentonite) injections?

If it sounds impossible, it’s because it is. Without excavation, there is no way to spread the mixture evenly along the walls. Even if it were spread properly, the mixture would eventually fail like other exterior treatment methods. This method was long ago de-bunked by the Ontario Department of Consumer Protection (among other agencies) and does not meet the required standards by Ontario Building Code as a legitimate waterproofing method. Many companies using this method were driven out of business, although there are a few still around.

Do we have to dig out our foundation to resolve the problem?

An interior drainage system can control water from flooding a basement, and is a more cost-effective method in certain situations, but does not waterproof a basement. If there are cracks in a foundation wall or floor, water will continue to enter into the basement and be collected by the water control system.

Over time, water penetration will continue to deteriorate and weaken the structure; walls subjected to high soil pressures (hydrostatic pressure) will eventually bow, bulge, lean, or completely buckle. Sealing a wall from the inside alone with interior crack patches will trap water inside the wall and actually speed up the deterioration of the wall.

What are the rust-coloured stains on my wall?

What is the white chalky substance on my walls?

What causes the musty smell in my basement?

Mould can go unnoticed, growing behind walls and under flooring. If it is suspected that there is unseen mould growth in your home, indoor mould growth should be addressed immediately. Please contact us and we will dispatch a certified mould inspector to inspect your home.

I put up new gutters, ran extensions away from the house and re-graded, so why do I still get water in my basement?

Why do I have cracks in my foundation walls and/or floor?

Cracks can pose serious short- and long-term problems: in the short run, cracks can be an easy means for water entry into your basement. In the long run, cracks can compromise the structural integrity of your foundation.

Large cracks, cracks that have visibly grown over time, or bowed or buckling walls need immediate attention. The average house places over 50 tons of weight on its foundation walls, so the integrity of the walls must be maintained!

Cracks in your basement floor can also be caused by settling and shifting in your foundation walls, in the footer underlying your foundation, or in the floor (or “slab”) itself. However, floor cracks are more frequently caused by hydrostatic pressure.

The water pressure from below the floor must escape somewhere, so it pokes a hole or crack in your basement floor. Water penetration through a foundation wall can ultimately deteriorate the foundation wall, reducing its strength, allowing movement in the wall itself.

Why didn’t my home inspector discover the problem?

A specialist is better equipped to detect the residual signs of water/moisture problems; even in the midst of a drought.

What if I plan to sell my home shortly?

There is a better way! Waterproof your home before putting it on the market and recoup the cost of the waterproofing when you sell it. A.C.C.L Waterproofing Systems’ transferable lifetime warranty assures the success of this strategy.

Should I use an interior sealer like Dry-Loc?

First, sealers are a “band aid” solution and do not address your real problem: water is penetrating through your foundation. The band aid will eventually fail and the water penetration will resume. In addition, sealers trap water within the walls, which can actually accelerate foundation deterioration. Also, like all other wall treatments, interior sealers do not solve the problem of hydrostatic water pressure from below your basement floor.

How do I begin to deal with the problem?

In most situations, an interior drainage system is the best way to stop floor water or flooding. However, every basement is different, and you should beware of companies that offer a “one size fits all” solution. At A.C.C.L Waterproofing Systems, our inspectors are experts in the field, and our inspections are free. Call us at 1-866-701-8484, or make a request online for a free inspection.

How can I tell where the water is coming from?

Hydrostatic pressure (water does not stack very well; immense pressure builds up around the foundation when the ground is saturated) will force water through cracks in your foundation walls and/or floor. Several other sources are probable, though these are not as easily noticeable.

Our licensed inspectors are trained to determine the exact source of your problem, and advise the most effective solution for your particular situation.
