Waterproofing Services in Markham Ontario

Water intrusion is one of the most damaging and costly problems a property owner can face. Our waterproofing services in Markham Ontario are designed to address the root causes of basement leaks, foundation cracks, moisture seepage, and inadequate drainage before they result in long-term structural damage.

We provide both exterior and interior waterproofing solutions. Exterior waterproofing involves excavating around the foundation, applying waterproof membranes and coatings, and installing drainage systems that direct water away from the structure. Interior waterproofing addresses active leaks through crack injection, interior drainage channel installation, and sump pump systems that manage water that enters the basement.

Our waterproofing solutions use proven, industry-grade materials backed by workmanship warranties. We inspect each foundation carefully, identify the source of moisture problems, and recommend the most effective and durable solution for your specific conditions. Protecting your foundation now prevents far more costly repairs in the future.

Underpinning in Markham Ontario

When a foundation no longer provides adequate structural support, underpinning in Markham Ontario is the professional solution. Oscar Demolition Ltd. specializes in foundation underpinning for properties experiencing settlement, visible structural cracking, basement lowering projects, and older structures requiring reinforcement to meet modern load requirements.

We apply a range of underpinning methods based on the specific conditions of each project. Mass concrete underpinning is the most traditional method, involving sequential excavation and concrete pours beneath the existing footing. Beam and base underpinning distributes the load across a reinforced beam system before transferring it to concrete bases. For more complex soil or access conditions, mini-pile underpinning provides deep load transfer with minimal excavation.

All underpinning work is executed in coordination with structural engineering assessments to ensure proper load transfer and long-term foundation stabilization. Our crews follow strict safety protocols throughout every phase, and we handle all required municipal permits for underpinning work in Markham Ontario.

Concrete Pouring in Markham Ontario

Oscar Demolition Ltd. delivers high-quality concrete pouring in Markham Ontario for residential and commercial applications. Our concrete work is built around proper preparation, quality materials, and skilled finishing techniques that produce results designed to withstand Ontario weather conditions, freeze-thaw cycles, and heavy loads over the long term.

We pour concrete for foundations, basement floor slabs, driveways, walkways and sidewalks, garage floors, footings, and retaining walls. Before any pour, our team prepares the site with proper grading, compacted base material, formwork installation, and steel reinforcement placement to ensure structural integrity from the ground up.

We use quality concrete mixes appropriate to each application, and our finishing crew is experienced with smooth trowel finishes, broom textures for traction, and decorative stamped concrete patterns for driveways and patios. Every pour is cured properly to maximize strength, durability, and resistance to cracking.
