FAQs

  • Is foundation waterproofing necessary?

    Foundation waterproofing is a crucial process that provides an impenetrable barrier around your home's foundation. It prevents water and moisture from penetrating the walls and causing potential damage. This process utilizes various techniques and materials, including sealants and drainage systems, which are specifically designed to keep water away from the structure of your home.


    Moreover, proper foundation waterproofing ensures that groundwater or rainwater does not seep into your basement or crawl space. It safeguards your property against the potential risks of water damage such as mold growth, structural damage, and decreased property value. Therefore, it's a worthwhile investment for every homeowner.


  • How long does the waterproofing process take?

    The duration of the waterproofing process largely depends on the size of your home and the complexity of the work required. On average, it can take anywhere between 2 to 5 days for a standard residential property. However, larger projects may require more time.


    For instance, if extensive excavation is required or if severe weather conditions slow down progress, it could extend beyond this timeframe. Regardless of the project size or complexity, our team always endeavours to complete their work efficiently without compromising on quality.


  • How often should I have my foundation inspected for leaks?

    It's a great idea for you to visually inspect your basement and or crawl spaces for water or dampness.. The best time to complete the inspection is after heavy rain or in the spring once the frost has left the ground.

    Water on the walls, on the floors or dampness are indicators that your foundation is not waterproof.


    Sometimes these issues can be fixed by making sure your eves downspouts are pointed away from the foundation and clear of debris.


    It's also important to note that building up gardens against the foundation of your home or building can cause water to collect around the foundation increasing the risk of a leak.


    Remember prevention is better than cure - catching potential problems early can save you considerable time and money in repairs down the line.


  • What are the signs that my foundation needs waterproofing?

    Several signs indicate that your foundation might need waterproofing. These include visible water stains on the walls or floors, a musty smell indicating mould or mildew presence, efflorescence (white, chalky substance on your walls), and dampness in your basement.


    In addition to these, if you notice cracks in your foundation walls or floors, it’s a clear sign that water is getting into your home. Additionally, issues like warped doors and windows can also suggest a problem with your foundation. If you observe any of these signs, it’s best to contact a professional for an inspection immediately.
