    Interior basement waterproofing in Toronto

    What is interior basement waterproofing?

    Interior basement waterproofing, distinct from exterior waterproofing, is executed entirely from within the confines of the structure, offering a unique approach to water management.

    This method becomes crucial when the interior walls of a structure are plagued with issues like water infiltration, mould and mildew growth, or excessive moisture accumulation. The primary goal of interior waterproofing is to fortify the building against these damaging elements, thereby providing a layer of long-lasting protection.

    Furthermore, it enhances indoor air quality by preventing the growth of mould and mildew, which are known to cause health issues. This added layer of protection is especially beneficial in regions with high humidity or frequent rainfall, where moisture problems are more prevalent.

    By adopting this method, homeowners can enjoy a safer, healthier, and more durable living space, securing their investment in the long run.

    When to choose Interior Waterproofing

    Interior basement waterproofing enhances the safety and comfort of your home, ensuring a healthier living environment for your family. Besides improving the immediate living conditions, this process also extends the longevity and increases the overall value of your property.

    Selecting a reputable and experienced service provider for this task is crucial. Waterproofing PD stands out in this regard, boasting a team of knowledgeable and skilled professionals dedicated to ensuring your utmost satisfaction with the completed work.

    The installation of interior basement waterproofing in Toronto and Southern Ontario residences serves multiple purposes. It not only addresses and prevents the harmful effects of flooding, moisture, and water leaks, but it also plays a vital role in enhancing your home’s energy efficiency. This improvement in energy efficiency can lead to reduced heating and cooling costs, contributing to long-term financial savings.

    The interior method of basement waterproofing is particularly beneficial when exterior waterproofing isn’t feasible due to specific site conditions or other constraints. By choosing this method, homeowners can effectively tackle persistent issues related to wet basements, ensuring a dry and secure foundation for their homes. This proactive approach not only safeguards the property’s structural integrity but also contributes to a more comfortable and sustainable living environment.

    Lack of access to exterior of foundation

    When the outside of the basement is difficult to access due to excessive moisture or other factors, it is the best solution to start waterproofing from the inside and getting the water out of the home. Interior basement waterproofing in this way is also less disruptive to daily life.

    Poor soil conditions

    Poor soils condition is of the most common problems that motivate us to waterproof the interior of the basement instead of exterior first. The moisture is often so concentrated that it does not allow the affected area to be excavated. In these circumstances, it is recommended that interior waterproofing and drainage process takes place as soon as possible to mitigate the damaging effects of water infiltration.

    Limited space between structures

    Sometimes it is just not physically possible to get the necessary equipment into space between structures on a property without causing unwanted and irreparable damage to one or both buildings. In these cases, it is best to try to solve the problem with interior basement waterproofing solutions.

    Cost factor

    If you have a limited budget, interior basement waterproofing in Toronto and Southern Ontario may be the way to go as it is generally less expensive than exterior basement waterproofing. Regardless of your budget, though, do not hesitate to contact us! We will work with you to choose the most affordable waterproofing package to fit your needs.

    Extra foundation protection

    An additional layer of waterproofing for the interior of your basement foundation is never overdone; more layers mean more protection for the structure.

    Moisture in the underground walls

    Water contains salts from the ground that are deposited in the wall. These salts accumulate over time and can cause serious damage to the walls of the foundation. To solve this, the inside of the walls must be covered with a waterproofing mortar that resists water under counter-pressure, is insensitive to salts, and is applied in a thick layer to maintain support.

    Frequently Asked Questions

    The final cost of interior waterproofing will depend on several factors, such as labor, materials required and the extent of pre-existing damage to the foundation. At Waterproofing PD, interior basement waterproofing starts at $75 per lineal foot. We offer free in-home inspections complete with a full estimate on cost, so there will not be any surprises.

    Depending on the extent of work required, waterproofing can be completed in as little as one day. Interior waterproofing in general is less disruptive than exterior waterproofing and is often done more quickly.

    In short – yes! Interior waterproofing protects your home from the damaging and corrosive effects of water infiltration. A basement that is shielded from dampness is far more appealing to homeowners than one that is inhabitable because of excess moisture.
