The difference

  • In an industry comprised of so many lookalike, make-a-quick-buck, and basement waterproofing franchise companies, with similar approaches and solutions…
A.C.C.L Waterproofing Systems stands alone.

The majority of basement waterproofing performed today comes from temporary water control companies, not waterproofing companies. Water control companies claim to do all types of waterproofing, but will always steer you to their method of dealing with a wet basement, usually a water control system, which in reality is not waterproofing at all.

In controlling the water problem these systems not only compromise the structural integrity of the home, but in most cases fail completely within a few years. Unlike us, many other “waterproofing” companies use the least costly materials to remedy the problem.

Waterproofing is only as good as the materials used to accomplish it, and will only last as long as the materials applied. Waterproofing is exactly what the name implies, if it is not waterproof it is subject to deterioration, and if non-deteriorative materials are not utilized it is a temporary fix at best. Waterproofing your basement is not something you want to do twice, and certainly shouldn’t have to do twice if done properly with the highest quality materials.

By employing the most talented and experienced foundation experts in the business, A.C.C.L Waterproofing Systems offers our customers a permanent solution specific to their wet basement circumstances. This not only assures satisfaction, but also saves our customers money in the long run.

At A.C.C.L, our core values drive everything we do. We believe that if you can help enough other people get what they want; you will get what you want. This holds true for the way we approach our customers, as well as the way we treat our valued team members.

We believe that it is better to under-promise and over-deliver, and in the end provide for our customers more than they expect. We strive to think long term and act with integrity in each and every decision we make. We love to help people, and we love what we do, that’s why we do it with perfection and this is what sets us apart from other companies.

A.C.C.L Waterproofing Systems, Ontario Basement Technologies and Mould Removal Corp. will eliminate all your wet basement related problems, large or small. We recommend what is necessary to solve your wet basement problem permanently.

Whether you have water coming through your basement walls, floor, cracks, doorways or basement windows, we can ultimately put an end to it by using the most effective, permanent, waterproofing materials and unsurpassed non-deteriorative drainage solutions in the industry.

A wet basement is more than just an inconvenience, and waterproofing against it becomes more than just a necessity. Discovering a wet basement leads you to an exhaustive, stressful cleanup as you race to protect your home from further damage.

Not only can a wet basement lead to serious structural damage to your home, but to the growth of mold and poor indoor air quality that can potentially damage your health. Homeowners with humid, damp, leaking basements are prohibited from using the valuable living and storage space that makes up one third of their homes.

The most cost-effective approach to adding tremendous value, and additional living space to your home is to eliminate your wet basement problem. The fact is that the problems in your wet basement do not stay in the basement.
Water penetration will ultimately lead to the deterioration and weakening of a foundation, undermining the structural integrity of the entire house. A wet basement can lead to mold infestation, which can also effect the whole home.

    • Our services include, complete and permanent basement waterproofing, partial exterior waterproofing and corner digs, foundation repair and structural restoration, foundation wall rebuilds, interior and exterior non-deteriorative drainage systems, certified mold removal & remediation, and total moisture control & indoor air quality solutions.

Foundation interior drainage systems are one of the most important aspects of residential construction. Drain tile systems are also one of the most misunderstood aspects. Because these systems are buried and cannot be easily modified or corrected, it is vitally important that they are installed correctlyFoundation drainage systems, which are installed properly, can serve a dual role.

Foundation drain tile systems are the means by which groundwater can be transported away from your basement. If you want a dry basement and a sound foundation, you must have an adequate foundation drainage system. The water content in the soil surrounding your house can fluctuate seasonally. There is always a point at which you can dig and hit water. Geologists often refer to this as the water table. This water table rises and falls in response to the amount of precipitation in any given time period. The water table in many parts of the country can rise to within a few feet of the surface during wet spells. Water will take the path of least resistance. If there is no exterior waterproofing water can go sideways through a crack in your foundation, or it can go down alongside your foundation into a pipe. I’m sure that you will agree that it is a better idea for the water to go down into the pipe.

Interior drainage systems work extremely well for many customers. Depending on your circumstances, this may be an effective solution. Many water control system companies claim to be waterproofers and offer this method as a solution to every basement water problem. If a company proposes opening the floor on the inside for any reason, they are offering an interior drainage system. Only an exterior excavation to the footer or bottom of the foundation accomplishes waterproofing. Never contract for a water control system if dampness, seepage, and or cracking on the walls are your concern, as this may result in further damage to your foundation.

Pressure relief systems, also known as drainage systems and French drains, are an extremely efficient way to prevent water seepage through the basement floor caused by hydrostatic pressure. Hydrostatic pressure is the force exerted by water against an item such as a foundation. When the groundwater levels outside the basement rise above the level of the floor, the basement acts like a boat in a pond. If a boat is sitting in water, water will leak in through any open cracks, holes or porous areas. It works the same way with a basement. Hydrostatic pressure can push water through hairline cracks. Symptoms of this are water coming up through the basement floor or water coming in at multiple locations.

Properly installed systems will remove the water before it has a chance to rise above the level of the basement floor. This water is then diverted to a sump well recessed in the floor where a pump discharges it to a safe and legal location. To accomplish this there are two popular methods of installation on today’s market, the top of footer method and the deep system method.

To de-water a basement from the interior, a perimeter drain must be installed. In cases where water is coming up through the floor, we prefer adding lateral (front to back) drain pipe to collect water before it comes in contact with the underside of the slab. The water is transported away from the basement, preventing floor water, and flooding. If a basement has a concrete slab floor this will entail breaking the floor at the walls and/or across the floor and installing drain pipe that leads to a sump-pump or gravity drain, and then re-pouring the broken sections of the floor. If grade conditions and slope of land are adequate to accommodate a gravity drain, or you build on a hillside, your drain tile pipe will simply ‘daylight’ or come to the surface. It is a much more reliable system, as you do not have to rely on electricity to discharge the water in a torrential rain, your system depends entirely on gravity to work. If you build on level ground, you have basically two choices, install a sump pit or a large buried french drain. A french drain pit is a large subterranean pit filled with gravel. The drain tile pipe runs to this pit and the water fills this pit. French drains do not work well in areas where the water table rises above the level of the French drain pit or the basement floor. A sump pit is installed inside the basement of your home. The drain tile pipe runs to this sump. The collected water is then mechanically pumped from the sump and away from the home.

Internally we are redirecting the water and thus not letting it remain standing in the structure of your basement. Remembering that we want to keep the structure, not just the living space, as dry as possible, we put the weeping tile beside the footer. You can keep the basement dry with a drain installed on top of the footer, or even with a “baseboard” system. However, using these last two methods, the footer is permanently high in moisture. This means that over time it will begin to crumble and start to disintegrate, impinging on the integrity of the complete building. As a repair, for an existing problem, the following happens.

  • Trench the floor slab.
  • Install a sump pump and connect new weeping tile to it. Connecting the weeping tile to a floor drain is possible, but generally not advised, in some instances.
  • If the walls are made with “block” drill holes into the hollows.
  • Install low-level drainage board.
  • Install weeping tile.
  • Install a layer of gravel.
  • Refinish the floor.
Whichever method you decide to use, get it done professionally as a job done properly protects your investment and should give you peace of mind in the form of a 30 years warranty.

The A.C.C.L Waterproofing Systems Advantage.

Drainage systems located on the top of the foundation footing are typically placed very shallow and actually reside above the bottom of the basement floor. While it could prevent water from rising to a level above the floor because of their slim profile these systems are low capacity. Additional problems arise because the concrete foundation floor is still sitting in moisture, moisture that can be wicked into the basement and cause dampness or, over long periods of time damage the concrete.

Deep systems reside next to the foundation footing below the basement floor. This system intercepts and removes any water that rises above the level of the foundation’s footing. A typical installation uses a four inch perforated pipe to direct the water to a sump basin where the water is then safely discharged from the home. Since these systems use four-inch pipe and can sit in a bed of ¾” drainage gravel they are considered high capacity. In extreme conditions a larger six-inch perforated pipe can be substituted for the four-inch pipe to help control flooding. The only real limitation of a deep system is the pumping power behind it.

A.C.C.L installs deep pressure relief systems coupled with one of the best primary pumps and back-up pumping systems on the market today. We fully guarantee our system to stop all sub-surface water infiltration where it is installed. We do not sub-contract our work, our foremen and crews have been with us for many years and they provide a clean and courteous installation meeting the highest standards for customer service in the industry.

The Complete Solution

Pressure relief systems are an ideal way to prevent hydrostatic water from entering your home. However when the electricity goes out, most likely during a horrible rainstorm, primary pumps cannot work. This is where our Battery Backup Systems are critical to maintaining a dry basement. We recommend that every system has a backup for times of a power outage, extreme precipitation and in the event of a primary pump failure.

Indoor air quality is also a primary factor to consider in your home. Inactive mold spores are in the air we breathe every day along with dust mites and other particulates. Filtering these particles out of the air along with humidity control is crucial to preventing a costly mold problem from happening to your home.

Air Handling Machines (Negative Air & Air Scrubbers)
Once containment has been established our crews use either a Negative Air Machine or a Neutral Air Scrubbing machine to significantly reduce the amount of airborne dust and debris inside the work area. Our units have the ability to move 750 to 2,000 cubic feet of air per minute and most are equipped with HEPA filtration. These air handling machines are just another example of how A.C.C.L will go above and beyond to provide the best in service and customer satisfaction.

Interior Foundation Coating

A.C.C.L’s interior foundation coating is a low odor, ready-mixed masonry waterproofing paint. Specially formulated to waterproof interior, exterior, above or below grade masonry walls. Ideal for use on cinder and concrete block, poured concrete walls, stucco, brick, retaining walls, and basement walls.

Our foundation coating is available in a white color that leaves a clean finished look to the foundation wall when complete.

Basement waterproofing should begin outside your home. Look for areas that contribute to the collection of water next to your foundation. Fill low areas so water flows away from your foundation. Check gutters for debris, and downspouts should extend at least 8 feet from the house. Service walks that settled and slope back to the house should be adjusted to flow away from your foundation.As the soil around your foundation becomes water-saturated, hydrostatic pressure forces water through the joint where your floor and wall meet.Water may affect your basement in various forms, either as a vapour or as a liquid. Water, as a liquid, does not always mean that you will see glaring evidence of water. The basement structure can retain a high moisture content prior to water becoming evident. The damage is slow, subtle and detrimental to your basement. This high moisture content is decaying the building. A.C.C.L Waterproofing permanently solves wet basement problems internally or externally. The method we recommend depends on the circumstances and the condition of your building.

Exterior Waterproofing

Exterior waterproofing requires excavation to the foundation footing, or the bottom of the foundation.
Regardless of your circumstances, whether you are experiencing seepage or dampness through the walls, exterior waterproofing will always solve your problem. If anyone suggests otherwise, they are trying to sell you a stand-alone interior water control system, this method of de-watering does not waterproof a basement and only prevents floor water.

Never contract for a water control system if dampness, seepage and or cracking on the walls are your concern, as this may result in further damage to your foundation.

Waterproofing the exterior of a foundation completely eliminates water and moisture penetration through the walls into a basement. For a basement to be absolutely waterproof, it needs to have protection from sub-surface water for all of the below-grade walls.

All of this protection must span from grade level down to the foundation footing or a depth deeper than the basement floor. The important difference is in the materials used to waterproof the walls. Most companies are using tar — the same sealant that was being used 20 years ago. Tar is not waterproofing; it is dampproofing. Tar cannot expand and bridge future cracking. Tar very quickly loses it’s elasticity and cracks. With the seal compromised, the whole process leading to water penetration and structural deterioration begins.

A.C.C.L Waterproofing utilizes today’s most advanced waterproofing materials to apply a superior multi-layer foundation seal that permanently eliminates water penetration.

We begin by repairing all cracks with a hydraulic cement which expands as it cures, to eliminate the damage. We then apply a portland cement-based waterproofing seal to completely fill any hairline cracks and seal mortar joints.
A second layer, made of an elastomeric membrane, is then applied; this polymer-based sealant remains pliable and expands to bridge any future cracking. This coat sets like rubber and provides an unsurpassed waterproof seal. A.C.C.L utilizes both trowel grade and heat spray-applied membranes. Finally, to obtain superior and permanent protection we hang an extremely durable dimpled Delta –MS membrane.

The plastic-dimpled core provides compressive strength to keep headwater pressure off the face of the wall, and creates a drainage space that allows high capacity flow to the foundation drainage system. The polymeric film provides additional protection to the elastomeric waterproofing membrane.

If you are going to have your foundation excavated, give yourself the peace of mind that comes from hiring a waterproofing company that utilizes the most advanced materials available, and applies them with the experience needed to get the job done right once and for all. There remains a very noticeable difference in a home that has been waterproofed with our process, compared to a home that has been damp-proofed with tar and plastic or other inferior methods.

Successfully blocking the sub-surface water from basement walls is not enough. The water that enters the ground around your foundation will not do just that, disappear, although sometimes it may seem that way.

We must engineer a drainage system to intercept the water that has been blocked by the waterproofing materials. Otherwise the water will cause immense pressure (hydrostatic pressure) to build up outside the foundation walls. Water doesn’t stack very well so it usually finds its way to the area under the basement floor and then rises from under the floor as it tries to seek its own level.

Disastrous floods can, and very often do, occur without a single drop of water penetrating the basement walls. Waterproofing without proper drainage is destined to fail, and vice versa in many cases. You would be better off having good drainage and no waterproofing! (a statement that one-size-fits-all water control system companies would love to sell everyone on).

It’s true that a good roof is not waterproof but since it drains so well, there’s not a problem. Let’s not forget, though, your roof is not surrounded by tons of backfill saturated with tons of water…you get the point. Basement drainage is much more complex. It has to be deeper than the basement floor, which is very deep in the ground.

There are three methods of moving the water that waterproofing has blocked from penetrating the walls:

One method is to install a weeping tile system to the city storm drain. Prior to connecting the new weeping tile, check the condition of the existing tile. It may require a pressure flush to ensure it will work properly. Install new weeping tile. Fill sides, under and above the weeping tile with gravel. (1 cubic foot per linear foot) Back fill grade, tamping approximately every foot.

The second method is installing a pump and a sump pit system.

The third is a gravity drain. A gravity drain is a downhill pipe sloped away from the house drain pipe (weeping tiles). It’s often referred to as a tail line. A gravity drain is the preferred method, but there must be a destination for this pipe, or pipes, well below the basement level to which the water can flow. If there is no such destination on the property nor a city storm drain, the second method of water disposal is unavoidable; a pump and sump pit system must then be used.

Exterior waterproofing and drainage is by far the best protection for a basement. It is used almost exclusively when houses are being built. However, in retrofit (re-doing other systems that failed) situations, older homes with established landscaping, connected utilities, air conditioners, patios, decks, additions, garages, etc., Exterior waterproofing can be at best impractical, if not close to impossible, so other very effective methods must be applied.
For a less expensive approach to correcting a flooding or leaky basement, see the section on interior de-watering systems.

Why Exterior Waterproofing?

As stated above, for a basement to be absolutely waterproof, it needs to have protection against sub-surface water for all of the below-grade walls, sealing a wall on the inside traps water within the wall and actually speeds up the deterioration of the wall, which could lead to foundation walls bowing and serious structural damage.


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 mold remediators will remove the mold spores, mildew, fungus, toxins and dead organic material from all surfaces, apply a superior mold resistant coating, and install a moisture control unit to prevent any recurrent mold 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.
