Do You Notice Water, Dampness or Musty Odors in Your Basement?

Many Hamilton homeowners experience a musty or wet basement due to aging foundations, porous concrete, or poor drainage. Moisture often seeps in through foundation cracks, basement walls, or floor joints—leading to air quality issues and hidden structural deterioration. 

At AquaBoss, we specialize in basement waterproofing in Hamilton with complete interior and exterior systems tailored to the city’s soil conditions and building styles. Interior waterproofing moves water out after entry, using drainage channels and crack sealants. Exterior waterproofing stops groundwater before it reaches the foundation by applying membranes, installing drain boards, and setting up weeping tile systems. These integrated systems help prevent sump pump overload, foundation cracking, and mold formation.

Every AquaBoss installation is designed for Hamilton’s freeze-thaw cycles, clay soil, and seasonal water table fluctuations. If you’re seeing these warning signs, book a free basement inspection today.

Comprehensive Basement Waterproofing Solutions in Hamilton

AquaBoss offers professional basement waterproofing and foundation repair services designed to protect Hamilton homes from water damage, foundation leaks, and long-term structural deterioration. Whether you're dealing with seasonal dampness, persistent seepage, or early signs of foundation stress, we deliver tailored waterproofing solutions based on your home’s structure, local soil type, and environmental exposure.

Effective basement waterproofing in Hamilton requires a layered moisture defense. Water can enter from beneath the slab, through cracked foundation walls, or around the footing—each requiring a dedicated method. 

At AquaBoss, we apply interior waterproofing systems to manage water after it enters and exterior systems to prevent intrusion before it starts. Every installation is engineered to withstand Hamilton’s elevated water table, clay-heavy soil, and winter freeze-thaw patterns, creating a durable, long-term barrier around your basement.

Foundation Repair & Structural Protection Services

Foundation repair services help stabilize Hamilton homes showing signs of basement wall stress, cracking, or settlement. These issues often result from groundwater pressure, shifting soil, or aging concrete foundations. At AquaBoss, we use structural solutions like epoxy injection, bench footings, steel bracing, or full rebuilds depending on damage severity. Our process begins with a full assessment of load distribution and soil conditions to select the right long-term fix for protecting your home’s value.

How much does basement waterproofing cost in Hamilton?

Basement waterproofing costs in Hamilton typically range from $65 to $250 per linear foot, depending on the method, damage severity, and condition of the foundation.

Our Basement Waterproofing Process: Step-by-Step

At AquaBoss, we follow a structured, step-by-step process for basement waterproofing in Hamilton. Our goal is to eliminate active leaks and prevent long-term water intrusion. Every phase is completed by our trained waterproofing team, using validated techniques that comply with Ontario Building Code and address the local soil, climate, and hydrostatic conditions found in Hamilton homes.

Step 1: Initial Moisture Inspection & Free Estimate

Our waterproofing process starts with a thorough on-site inspection. A certified AquaBoss technician checks basement walls, floor joints, drainage points, and signs of moisture or mold. You receive a written estimate that includes system recommendations, pricing, and full warranty details.

Step 2: Problem Diagnosis & Custom Plan

We identify the root cause of your basement issue—whether it's rising groundwater, blocked weeping tile, or foundation wall seepage. Then we design a tailored solution using the appropriate waterproofing method, whether interior drainage or exterior excavation. The plan includes timelines, costs, and any code-compliance requirements for Hamilton.

Step 3: Exterior Excavation or Interior Prep

If exterior waterproofing is needed, we excavate the foundation wall to install membranes and drainage layers. For internal waterproofing, we cut sections of the floor in your basement to install drainage channels and sump infrastructure. The method depends on site access, soil conditions, and foundation type.

Step 4: Sealing, Crack Repair & System Installation

We install multi-layer protection systems including drainage panels, vapor barriers, and sealants. Foundation cracks are sealed using high-pressure epoxy or polyurethane injection. This step may include sump systems, backwater valves, and French drains as defined in your waterproofing plan.

Step 5: Backfilling, Site Clean-Up & Final Walkthrough

We restore all disturbed areas, including backfilling exterior trenches with clean gravel or resealing interior slab sections. A final system test ensures functionality. You receive full documentation to support insurance, resale, or rebate programs in the Hamilton area.
