Foundation repair services are essential for stabilizing homes with basement foundations in Markham, especially when signs of stress, cracks, or shifting appear. These problems often arise due to water infiltration, soil movement, or long-term settlement, particularly in older homes built with block or unreinforced concrete. Common issues include bowing walls, vertical cracks, sloped floors, and heaving slabs.
At AquaBoss, we address these with techniques such as epoxy injection, steel bracing, bench footings, or complete rebuilds when necessary. We begin by evaluating the foundation's load, water pressure surrounding the home, and soil movement. Then, we implement the appropriate long-term repair to prevent failure and safeguard your property's value. Markham's proximity to the Rouge River can lead to unique soil conditions, making our thorough assessment crucial.

At AquaBoss, we focus on basement waterproofing through a detailed, step-by-step procedure. Our aim is to address current leaks and prevent future moisture issues. Each stage is managed by skilled AquaBoss experts. The process includes inspection, system design, expert installation, and a final walkthrough. We utilize proven systems that comply with the Ontario Building Code, crucial for Markham's varied soil types.
Initially, a certified waterproofing specialist conducts a comprehensive evaluation of foundation walls, floor joints, drainage points, and humidity levels. We inspect for cracks, stains, efflorescence, mold, and sump failure indicators. You'll receive a written estimate that outlines the scope, system type, pricing, and warranty details.
Next, we determine the underlying issue, whether it's hydrostatic pressure, surface pooling, or weeping tile failure. We then align it with the right solution. Your plan will specify if interior systems like sump pumps or vapor barriers are necessary. Sometimes, exterior excavation is essential. The plan also covers project timeline and compliance measures.
For exterior waterproofing, we excavate the foundation wall to expose and clean the surface. For interior solutions, we remove floor sections along perimeter walls to install drainage channels and sump infrastructure. The method chosen depends on site access, soil depth, and wall type, considering Markham's unique environmental factors.
We implement multi-layer protection systems, including waterproof sheeting, drainage panels, and humidity-blocking vapor shields for thorough protection. Cracks are sealed with high-pressure epoxy or polyurethane injections. Sump pits, backwater valves, French drains, and weeping tiles are installed according to your custom plan.
Exterior trenches are backfilled with clean fill and gravel. Interior areas are sealed and restored using top-quality waterproofing materials. Our waterproofing team conducts a final system test. We then review the completed work and provide documentation, which is beneficial for resale, insurance, or rebate programs.
Immediate action is crucial when water damage strikes. Basement flooding, sump pump malfunctions, or foundation leaks demand swift intervention. These issues can lead to mold, foundation shifts, and costly repairs.
