How Our Foundation Waterproofing Works

Surface Preparation & Repair

  • We begin by exposing the foundation wall and cleaning it thoroughly to identify every defect. Any existing issues are handled via professional crack repair using high-grade hydraulic cement, ensuring a smooth and solid surface for the protective layers.

Multi-Layer Membrane Application

  • A thick, rubberized waterproofing membrane is applied to the entire exterior wall. This creates a seamless, flexible, and watertight barrier that prevents moisture from penetrating the concrete, even during heavy rain or Toronto’s freeze-thaw cycles.

Drainage System & Protection

We install a specialized drainage board to protect the coating and redirect water downward. At the base, a new perforated weeping tile or french drain installation is laid to collect water and carry it safely away from your home, ensuring a permanently dry basement.

    Our Foundation Waterproofing Solutions

    At Leaquida, we tailor our foundation waterproofing services to the unique needs of each property. Whether water is seeping through basement walls, pooling around the foundation, or causing structural issues, we offer reliable solutions.

    Interior Foundation Waterproofing

    Interior waterproofing is ideal for managing moisture inside a basement. This method is often chosen when exterior excavation isn’t practical.

    Our process includes:

    • Sealing Cracks & Joints – We use durable sealants to close gaps that allow moisture inside.
    • Drainage System Installation – French drains and weeping tiles help channel excess water away.
    • Sump Pump Installation – A reliable sump pump removes standing water efficiently.
    • Moisture Control Solutions – Dehumidifiers and ventilation improvements keep humidity levels balanced.

    If you’re experiencing damp walls or musty odours, foundation waterproofing near me services from Leaquida can provide a permanent fix.

    Exterior Waterproofing Foundation Solutions

    For maximum protection, exterior waterproofing services create a strong barrier against groundwater and rain infiltration.

    Our approach includes:

    • Excavation & Inspection – We expose the foundation to locate problem areas.
    • Crack & Joint Sealing – High-performance sealants prevent further damage.
    • Waterproof Membrane Installation – A durable membrane is applied to shield the foundation from moisture.
    • Drainage System Upgrades – Weeping tiles and sump systems redirect water safely.
    • Grading Adjustments – Ensuring proper slope around the property prevents water accumulation.

    If you need foundation waterproofing companies that offer full exterior protection, Leaquida delivers reliable solutions.

    Factors Affecting Foundation Waterproofing Cost:

    • Extent of Water Damage – Repairs for existing cracks and structural issues impact pricing.

    Is DIY Foundation Waterproofing a Good Idea?

    While DIY projects can be rewarding, exterior foundation waterproofing is a massive undertaking that involves significant risks and specialized labor. Before you grab a shovel, consider these critical factors:

    • Complex Excavation Risks: Digging 6 to 8 feet down around your foundation is dangerous. Without professional shoring, trenches can collapse, damaging underground utilities or even your home’s structure.
    • Professional-Grade Materials: Retail-grade sealants often fail during extreme freeze-thaw cycles. We use industrial-grade membranes and specialized hydraulic cements that retail products simply cannot match.
    • The “Hidden Leak” Trap: Water often travels behind walls. DIYers frequently seal the wrong area, leaving the real issue untouched. A professional basement leak repair is essential to stop moisture at its origin and prevent mold growth.
    • Lack of Certified Warranty: A DIY fix has zero resale value. When selling your home, buyers require a transferable warranty from a licensed contractor to satisfy home inspectors and close the deal.

    City of Toronto Rebate for Basement Flood Protection

    Homeowners can significantly reduce the cost of securing their property through the city’s basement flooding protection subsidy program. While the program specifically covers devices like backwater valves and sump pumps, these installations are most effective when combined with a professional foundation waterproofing strategy. By addressing exterior drainage and weeping tiles alongside subsidized upgrades, you ensure comprehensive protection against groundwater and sewage backups. As a licensed contractor, Leaquida ensures all related work meets municipal standards, helping you qualify for available financial assistance while creating a permanently dry and safe home environment.

    Reviews about us

    Quick, professional and at very reasonable cost. No hidden costs. The installation was complicated as the municipal sewage backed up when the pipe was cut, but the team did not complain despite working in harsh conditions.

    Lev, Whitby Vacancy

    Leaquida Waterproofing was prompt, courteous and thorough. We would recommend to anyone. We had a backwater valve installed. I called Sunday, got a quote Monday, has the work done the following Monday (including issuing of building permit).

    Trisha Grant Vacancy

    They have installed sump pump system in our house. They were very much on time and during the installation they have worked very clean. You may rely on their advises. Highly recommended.

    FAQ about Foundation Waterproofing in Toronto

    • What is the best method for foundation waterproofing?
      The best method depends on the severity of water intrusion. Exterior waterproofing foundation solutions provide maximum protection by sealing the outside walls and installing drainage systems. Interior foundation waterproofing is effective for managing moisture inside basements through sealants, sump pumps, and interior drainage.
    • How much does foundation waterproofing cost?
      The foundation waterproofing cost varies based on the size of the foundation, the extent of water damage, and the chosen waterproofing method. Interior waterproofing is usually more affordable, while exterior waterproofing offers the most long-term protection but requires excavation.
    • How do I know if my foundation needs waterproofing?
      Signs that you may need foundation waterproofing services include damp walls, basement leaks, musty odours, mould growth, and visible cracks in the foundation. If left untreated, water infiltration can weaken the structure and lead to costly repairs.
    • Can waterproofing increase my home’s value?
      Yes! Residential foundation waterproofing protects your home’s structure, improves indoor air quality, and prevents future repairs. A dry, well-maintained basement is a key selling point for potential buyers.
    • Does foundation waterproofing improve energy efficiency?
      Yes. By controlling moisture levels with professional foundation waterproofing services, you reduce the humidity your HVAC system has to manage. Dry walls provide better insulation, leading to lower heating and cooling costs year-round.
    • Is foundation waterproofing near me available for commercial buildings?
      Absolutely. We provide both residential and commercial waterproofing solutions across Toronto. Our team handles large-scale projects, ensuring industrial foundations meet safety standards and remain protected from water damage.
    • Can I waterproof my foundation if I live in a townhouse?
      Yes. For properties with limited exterior access like townhouses, we often recommend interior foundation waterproofing. This protects your unit without needing to excavate shared areas or neighboring properties.
    • How does soil grading affect my foundation's safety?
      Even the best exterior waterproofing foundation system needs help. We adjust the grading around your home to ensure a proper slope, directing rainwater away from the foundation to prevent water accumulation.
    • Will waterproofing stop my basement walls from feeling cold and damp?
      Yes. Interior waterproofing and moisture control solutions, such as vapor barriers, significantly reduce dampness. This eliminates that "basement feel" and improves the overall indoor air quality of your home.
    • Can water enter through the joints between the floor and the wall?
      Yes, this is a common entry point. Our interior foundation waterproofing includes sealing these specific joints and installing drainage systems to catch water before it reaches your basement floor.
    • How long do the waterproof membranes last?
      The high-performance membranes we use for exterior waterproofing services are designed to last for decades. They are resistant to soil chemicals and mechanical damage, ensuring your foundation stays dry for the long term.
