Internal Waterproofing Procedure

A.C.C.L Waterproofing Systems is a Family Owned and Operated,
Advanced Basement Waterproofing and Foundation Drainage Systems,
Certified Mold Removal and Remediation, and Basement Remodeling and Finishing.

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 correctly Foundation 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.

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.
  • 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.
  • 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.

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.

A.C.C.L Waterproofing Systems stands alone. Click to see why.

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.
