Interior Basement Waterproofing: Vapor Barriers & Sealants

Interior waterproofing is essential when moisture seeps through porous walls or under the foundation slab. Our team installs subfloor drainage systems, vapor barriers, and sealants. For structural cracks, we use hydraulic or polyurethane injections, depending on the wall type and depth. This method is perfect for homes in Markham with limited exterior access or signs of hydrostatic pressure.

Exterior Basement Waterproofing: Excavation, Membranes & Drain Boards

Exterior waterproofing systems safeguard your foundation by preventing groundwater from contacting basement walls. This process includes excavation, applying a waterproof membrane, and installing drainage panels with a weeping tile system. It effectively stops water from reaching the basement walls and is the most dependable solution for long-term saturation and wall pressure, crucial for Markham's variable weather conditions.

Sump Pumps for Basement Flood Prevention

Sump pump systems are designed to remove groundwater that accumulates beneath the basement floor. At AquaBoss, we provide sealed pits equipped with high-capacity pumps, backflow prevention, and battery backups to ensure functionality during storm-related power outages. Each system is installed with proper discharge routing and overflow protection. This ensures your basement in Markham stays dry, even during power outages caused by severe weather.

French Drains, Window Wells & Drainage Control

French drains are designed to collect and redirect groundwater, preventing pressure buildup around your foundation. Window wells protect below-ground windows from water accumulation and leaks, particularly during Markham's heavy rainfalls, ensuring your basement stays dry and your foundation is waterproofed effectively. These passive systems are perfect for Markham homes with poor surface grading or older window frames. At AquaBoss, we incorporate these solutions into comprehensive perimeter waterproofing plans, offering protection from every angle.

Drain Cleaning & Perimeter Drain Repair

Blocked perimeter drains can cause a damp or wet basement, even if your waterproofing system is operational. Our team conducts camera inspections, hydro-jetting, and snaking to clear blockages from soil, clay, or root intrusion. We also adjust drainage slopes and replace collapsed weeping tiles to ensure water stays out of your basement and maintains proper flow. These services are crucial for both internal and external waterproofing systems, especially in areas like Markham with clay-heavy soil.

Backwater Valve Installation

Backwater valves are an effective way to prevent flooding by stopping sewage from reversing into your home. We install valves that comply with municipal codes, blocking reverse flow and meeting all local standards. This protection is vital for preventing basement leaks, particularly in Markham's older neighborhoods with aging sewer systems.

Battery Backup Sump Systems

Power outages from storms can leave standard sump pumps inoperative just when they are most needed. Our battery backup systems kick in during blackouts, ensuring your basement in Markham stays dry and secure even without electricity. These systems are crucial for waterproofing against rising groundwater and provide the best protection during severe weather events.

Drain Snaking & Pipe Cleaning

A damp or wet basement often results from clogged pipes and blocked weeping tiles. We employ camera inspections and high-pressure snaking to clear out sediment, roots, and debris that hinder flow. This vital service enhances full-system drainage performance and can be a cost-effective part of any basement waterproofing project, especially as part of regular wet basement repair strategies.

Drain Line Repair & Pipe Replacement

Chronic leaks and flooding can stem from broken or misaligned drain lines. Our team focuses on repairing only the damaged sections, preserving your yard and shielding your basement from water intrusion. This service is key when your waterproofing project relies on dependable subsurface drainage. It's a common inclusion in many Markham basement waterproofing plans for homes with older or compromised infrastructure.

Bench Footings & Slab Replacement

Bench footing installation offers a stable alternative to full basement underpinning, particularly in older or compact homes in Markham. We pour reinforced concrete along wall perimeters and replace floor sections in your basement where cracks or settlement have appeared. This structural approach is frequently paired with both interior and exterior waterproofing to ensure comprehensive foundation support and long-lasting water protection.
