Our Most Common Waterproofing Services in Chicagoland

Interior Drain Tile Systems

An interior drain tile system is a type of waterproofing system for basements or crawl spaces that helps to manage water intrusion and prevent flooding. It typically involves installing a perforated pipe or “tile” along the perimeter of the basement or crawl space, which is then covered with gravel or crushed stone.

When water enters the basement or crawl space, it is directed toward the drain tile and flows into the perforations, carrying the water away from the foundation and out of the house. The water is typically directed towards a sump pump, which pumps the water out of the house and away from the foundation.

Overall, an interior drain tile system can effectively prevent water damage and maintain a dry, healthy living space.

Exterior Drain Tile Systems

An exterior drain tile system is a type of waterproofing system for buildings designed to manage groundwater and surface water before it enters the foundation of the building.

It typically involves excavating the soil around the perimeter of the foundation and installing a perforated pipe or “tile” along the bottom of the excavation. The pipe is then covered with gravel or crushed stone, which allows water to flow toward the pipe and into it.

The pipe is then typically directed away from the building and towards a drainage system, such as a storm drain or a natural slope in the terrain, where the water can safely and effectively drain away from the building.

An exterior drain tile system can effectively prevent water damage to the foundation of a building and help maintain a dry, healthy living space. However, it can be more expensive and disruptive to install than an interior drain tile system, as it requires excavation around the perimeter of the building.

Wall Crack/Leak Repair

The best way to fix basement cracks depends on the severity and cause of the crack. For small, non-structural cracks, filling them with an epoxy or polyurethane injection can be an effective solution. We use industry-leading products and time-tested methods to give you long-lasting, guaranteed results.

For larger or more severe cracks, it’s important to determine the underlying cause of the crack and address it first, such as by fixing drainage problems or reinforcing the foundation.

Sump Pumps & Battery Back-ups

A sump pump is typically needed when you have a basement or crawl space that is prone to flooding or water infiltration. If you notice water pooling in your basement or crawl space during heavy rains or snowmelt, or if you have a high water table in your area, a sump pump can help to remove the water and prevent damage to your home.

A battery backup for your sump pump is recommended if you live in an area that is prone to power outages or if you rely on your sump pump to protect valuable items or finished living spaces in your basement. In the event of a power outage, a battery backup will allow your sump pump to continue running for a period of time, helping to prevent flooding and water damage.

Our Waterproofing Process

Our typical process for waterproofing a basement are as follows:

  1. Assessment: We will assess your basement to identify the source of water entry and determine the extent of the damage. This may involve examining the foundation, walls, and floor of your basement, as well as checking for any cracks or leaks.
  2. Preparation: Before waterproofing can begin, we will need to prepare the area by removing any debris, sealing off any pipes or ducts, and ensuring that the basement is dry.
  3. Crack repair: If there are any cracks or gaps in the foundation, walls, or floor of your basement, we will fill them with an industry-best waterproof sealant to prevent water from seeping through.
  4. Interior waterproofing: When needed we install an interior drainage system to channel water away from the foundation and out of the basement. This may involve installing a sump pump to remove water, or a French drain system to direct water away from the basement.
  5. Exterior waterproofing: In other cases, we may recommend exterior waterproofing to prevent water from entering the basement in the first place. This may involve excavating around the foundation to install a waterproof membrane or coating, or installing a drainage system around the perimeter of the house.

Overall, we will take a comprehensive approach to ensure that your home is fully protected from water damage.

Mold Removal & Remediation

mold removal, aurora, il, crs basement waterproofing

Mold removal and remediation refer to the process of identifying and eliminating mold growth from a building or structure, as well as taking steps to prevent future mold growth. Here are the general steps involved in mold removal and remediation:

  1. Identify the mold: A professional mold inspector will conduct a thorough visual inspection and may also take air or surface samples to identify the type and extent of the mold growth.
  2. Contain the area: The affected area will need to be sealed off to prevent the spread of mold spores to other parts of the building. This may include using plastic sheeting, airlocks, or negative air pressure machines.
  3. Remove the mold: All visible mold growth and contaminated materials will need to be removed and properly disposed of. This may include cutting out drywall or flooring, or using specialized cleaning techniques to remove mold from non-porous surfaces.
  4. Clean and disinfect: After the mold has been removed, the affected area will need to be thoroughly cleaned and disinfected to kill any remaining mold spores and prevent future growth.
  5. Repair and restore: Any damaged materials will need to be repaired or replaced, and the affected area will need to be restored to its pre-mold condition.
  6. Prevent future mold growth: To prevent future mold growth, it may be necessary to address any underlying moisture issues, such as leaks or poor ventilation. This may include installing dehumidifiers or ventilation fans, or making structural repairs to improve drainage.

It’s important to note that mold removal and remediation is a complex process that requires specialized training and equipment. It’s always best to consult with a professional mold remediation company to ensure that the job is done properly and safely.

Egress Basement Windows

Egress windows are required in certain circumstances to provide a safe means of exit from a basement or below-grade space. Here are some situations where egress windows are needed:

  1. Basement bedrooms: If a basement space is used as a bedroom or a sleeping area, egress windows are required. This is to ensure that occupants can safely exit the space in case of an emergency, such as a fire.
  2. Finished basements: If a basement is finished, it must have at least one egress window. This is to provide a safe means of exit in case of an emergency.
  3. Basements with habitable space: If a basement has any habitable space, such as a family room, game room, or exercise room, it must have at least one egress window.
  4. New construction: In many jurisdictions, egress windows are required by building codes for any new construction that includes a basement or below-grade space.
  5. Remodeling or renovations: If you are remodeling or renovating your basement or below-grade space, you may be required to install egress windows to meet building code requirements.

It’s important to note that the exact requirements for egress windows may vary depending on your location and local building codes, so it’s always best to consult with a building professional or local building department to ensure that you are meeting all requirements.

Cinder Block Foundation Repair

Repairing a cinder block foundation can be a complex process and the best way to repair it will depend on the specific issue that needs to be addressed. However, here are some general steps that may be involved in repairing a cinder block foundation:

  1. Identify the problem: Before starting any repair work, it’s important to identify the cause of the problem. This could include issues such as cracks, bulging walls, or water damage.
  2. Prepare the area: The area around the damaged section of the foundation will need to be cleared of any debris or loose materials. This will make it easier to work on the foundation and ensure that the repairs are properly anchored.
  3. Install reinforcement: Depending on the extent of the damage, it may be necessary to install reinforcement to strengthen the foundation. This could include steel beams, wall anchors, or carbon fiber strips.
  4. Fill cracks: If there are cracks in the foundation, they will need to be filled with an appropriate sealant or epoxy. This will help prevent water from seeping into the foundation and causing further damage.
  5. Waterproof the foundation: To prevent future water damage, the foundation may need to be waterproofed using a specialized membrane or coating.
  6. Restore the exterior: Once the repair work is complete, the exterior of the foundation will need to be restored. This could include patching any holes or gaps, repainting or sealing the surface, and installing proper drainage around the foundation.

Custom Window Well Covers

Window well covers can provide a number of benefits for homeowners, including improved safety, protection from the elements, and enhanced energy efficiency. Here are some factors to consider when deciding if your window wells need covers:

  1. Safety: If you have children or pets, or if your window wells are located in a high-traffic area, covers can help prevent accidental falls or injuries. Covers can also deter intruders from entering your home through the window wells.
  2. Protection from the elements: Window well covers can help keep out rain, snow, leaves, and other debris, which can prevent damage to your windows and foundation.
  3. Energy efficiency: Covers can also help improve the energy efficiency of your home by preventing drafts and reducing heat loss through the windows.
  4. Maintenance: If you have window wells that frequently fill with debris or water, covers can help reduce the amount of maintenance required to keep them clean.
  5. Aesthetics: Depending on the style of your window wells and covers, covers can also enhance the overall appearance of your home.

Ultimately, the decision to install window well covers will depend on your specific situation and needs. If you’re unsure whether or not your window wells need covers, you can consult with a professional contractor or home inspector who can help you determine the best course of action.
