Waterproofing Compounds & Sealants

  • Waterproofing compounds and sealants prevent water from penetrating surfaces, which will protect your home from moisture damage.

  • Types of Waterproofing Compounds/Sealants:

    Liquid Waterproofing Membranes: These are applied as a liquid and cure to form a flexible, waterproof membrane. They are commonly used on roofs, balconies, and foundations. They are good for irregular surfaces and can accommodate movement.

    Cementitious Waterproofing: Made from a mixture of cement, sand, and additives, these compounds are applied as a slurry. Ideal for basements and water tanks. They have strong adhesion and durability but are less flexible than liquid membranes.

    Bituminous Waterproofing: Made from asphalt or tar, these products are often used in sheet form or as a liquid. They are commonly used on roofs and below-grade applications. They are excellent for areas exposed to water but can be affected by UV light.

    Polyurethane Sealants: These are flexible sealants that can be used in various applications. Ideal for sealing joints and cracks in concrete, roofs, and around windows.

    Silicone Sealants: Flexible and durable, silicone sealants are resistant to moisture and temperature changes. They are commonly used in bathrooms, kitchens, and around windows and doors.

    Tar-Based Sealants: These are typically made from asphalt or coal tar and are known for their waterproofing properties. They are ideal for sealing roof penetrations, such as vents, pipes, and flashing. They are often used in flat roofing systems. They have excellent adhesion and durability, and are resistant to water and UV exposure. However, they can be messy to work with and may require a primer for optimal adhesion.

    Marine Sealants: These sealants are designed for use in marine environments but are also effective for roofing applications. They are often silicone or polyurethane-based. These are suitable for sealing around roof penetrations, gutters, and other areas exposed to water. They are highly flexible, resistant to water, and can withstand harsh weather conditions. They are also often resistant to mould and mildew.

    Considerations When Buying:

    Application Method: Choose a product that best suits your application method (brush, spray, or trowel).

    Surface Compatibility: Ensure the sealant is compatible with the surface you are treating (concrete, wood, metal, etc.).

Window Well Covers

  • Window well covers can help prevent water from entering the home through ground level windows.

  • When choosing a window well cover it is important to consider factors such as the size, climate (temperature, rainfall and snow load), the likelihood of flooding, and the amount of natural light desired.

    Plastic window covers are the most common but are also very brittle and prone to cracking. Consider using UV-resistant (Polycarbonate) window covers especially on south-facing windows to reduce the chance of cracking.

    Note: Only install window well covers where fire escape requirements permit.

  • Anywhere from $20 - $200 depending on size and type of window well cover. Some window wells may need specialty-made covers which could cost more.

  • No available rebates found, though check local hardware stores for sales.

Downspout Extenders & Splash Blocks

  • Extends the downspout to carry water further away from the foundation of the home.

  • The extender should be able to direct water at least 2 meters away from your home's foundation.

    Splash blocks are recommended at the end of the extender to slow down the water and spread it over a larger area, allowing it to be absorbed into the ground faster.

  • Both downsput extenders and splash blocks can cost anywhere between $10-$30.

  • No available rebates were found. Check local suppliers/retailers for offers.

Sump Pumps

  • There are two main types of sump pumps, pedestal sump pumps and submersible sump pumps. Pedestal sump pumps sit above the sump basin and the basement floor, with an impeller at the bottom to force water up and out of the pit. Submersible sump pumps sit in the water and have an impeller within the motor casing.

    No matter which pumps you intend to use, you should always have a backup in case of a power outage or primary pump failure.

  • Capacity: For most residential applications, a pump capacity of 2500 GPH at a 10-foot head is often sufficient. For larger basements or areas prone to flooding, pumps with higher capacities may be needed.

     Switch Mechanism: Barometric switches activate when they sense pressure from water. Tethered float switches activate when the water forces a floating ball to a certain height. These switches can get caught between the pump and walls of the sump pit, or the backup pump. Vertical float switches are known to be more reliable because the float is less likely to get stuck. The most reliable vertical float switches also come with a cage protecting the switch, these are also known as "reed" switches.

    Pump Housing: Pumps with metal or cast-iron housing can better dissipate the heat from the motor and are considered more reliable, especially in places with greater temperature swings (like if your basement isn’t heated).

    Filter system: The filter helps keep debris out of the impeller so that the motor can run smoothly. If you have stone or clay in your sump pit a good filter is recommended. Look for filters with a large surface area, and avoid filters with fine openings that could get jammed with silt.

    Battery backup: Marine-grade batteries are considered more reliable in areas of high flood risk. It is important to regularly test your backup sump pump system.

  • The cost of a sump pump will vary on the type , make and size of the model you choose, but you can expect to pay between $100-$400.

  • Charlottetown’s Flood Protection Rebate Program helps residents protect their homes through the installation of flood protection devices.

    Eligible flood protection devices include:

    - Sump Pumps

    - Back up battery systems for sump pumps

    - Water alarm/detection devices

    The Town of Stratford Sump Pump Redirection Rebate Program provides a rebate up to $2000 to eligible property owners who disconnect their sump pump or storm drain system from the municipal sanitary sewer system and redirect it to the exterior of the building, allowing the water to run into ditches, swales, storm catches, etc.

Backwater Valves

  • Backwater valves, also known as backflow preventers or sewer backflow valves, are devices installed in a plumping system to prevent sewage or wastewater from flowing back into a building. They are are particularly important in areas prone to flooding or where the municipal sewer system may become overwhelmed. These valves are typically installed in basements or crawl spaces close to the main sewer line.

    Proper placement is crucial for effective operation. Always make sure the valve complies with local plumbing codes and regulations. .

  • Types of Valves: There are two main types of backwater valves mechanical and automatic. Mechanical valves use a flap or gate that opens in one direction and closes when backflow occurs. Automatic valves are designed to automatically close when backflow is detected, often utilizing a float mechanism.

    Size: Ensure the valve is the correct size for your plumbing system, it should match the diameter of your sewer line. Common sizes include 2-inch 3-inch and 4-inch diameters.

    Material: Look for durable materials that can withstand corrosive environments, such as PVC or ABS. The material should be suitable for the type of wastewater it will handle. Some valves come with see-through covers so you can quickly see the water is trying to come back up into the home.

    Maintenance: Since these valves should be regularly cleaned it is important to get a valve that is easy to access for cleaning. We recommend valves that have a removable cover for easy access and a test port which allows you to check if the valve is functioning correctly.

  • Can cost anywhere between $30-$150.

Sandbags

  • Sandbags can be stacked or lined up to create a temporary barrier and divert water away from the home or other infrastructure. They absorb the water’s impact, and can help in preventing erosion. Sandbags can also be used as anchors to secure objects that could otherwise be swept away by flood waters.

  • The most common size sandbag is 14×26 inches. The weight will depend on how much sand its filled with, but typically a sandbag weighs between 25 and 40 pounds.

    Pref-filled sandbags can be a convenient option. If you plan on making your own sandbags, make sure you are using heavy-duty plastic or burlap bags that can withstand water pressure. Only fill the sandbags about halfway to two-thirds full to allow easy handling and stacking. When stacking, place them in a staggered pattern like bricks to create a stable barrier.

  • Pre-filled sandbags can cost anywhere from $3-$5 per bag.

    Making your own is usually more cost-effective. Bags cost between $0.30 - $1.50

Surge Protectors

  • Surge protectors are devices designed to protect electrical equipment from voltage spikes, commonly known as surges. These surges can occur due to various reasons, such as lightning strikes, power outages, or fluctuations in the electrical grid. Surge protectors work by diverting excess voltage away from connected devices, helping to prevent damage.

  • Types of Surge Protectors: There are different types of surge protectors, including power strips with surge protection, wall-mounted surge protectors, and whole-house surge protectors that protect the entire electrical system. Whole House surge protectors at your electrical panel are highly recommended. If you go with this option try to find a resettable circuit breaker which allows you to reset the surge protector after it has absorbed a surge, rather than having to replace it. When buying power strips with surge protection, look for ones with an indicator light so you know your sensitive electronics, such as TVs, computers, and kitchen appliances are protected.

    Joule Rating: This indicates the energy absorption capacity of the surge protector. A higher joule rating means better protection. Look for surge protectors with at least 1,000 joules for basic protection, and higher ratings for more sensitive or expensive equipment.

    Clamping Voltage: This is the voltage level at which the surge protector will start to divert excess voltage. A lower clamping voltage means better protection, as it will react to surges sooner. Look for a clamping voltage of 330V or lower for optimal protection.

    Response Time: This refers to how quickly the surge protector can react to a surge. A faster response time means better protection for your devices. Look for surge protectors with a response time of less than 1 nanosecond.

    Number of Outlets: Consider how many devices you need to protect. Surge protectors come with various outlet configurations, so choose one that fits your needs.

    Type of Protection: Some surge protectors offer additional features like EMI/RFI filtering, which helps reduce electromagnetic and radio frequency interference, improving the performance of connected devices.

  • Wall-mounted and power strip surge protectors can range between $25-$70.

    Whole house surge protectors can range from $50 -$500 depending on the brand and model.
