Stage 1: Superior Site Preparation, Fabric Reinforcement & Compaction
Every durable concrete project starts with a strong base.
- High-performance equipment suited for any terrain.
- 98% compaction rating with our advanced RCM process.
- 4”–12” compacted gravel base, customized to the slab thickness.
- Multi-lift compaction to eliminate settling or shifting.
Geotextile Fabric Installation:
- Prevents soil migration into gravel, ensuring permanent stability.
- Stops moisture buildup, protecting against frost heave and erosion.
- Creates a barrier that eliminates contamination and weak spots.
Why We’re Better: Most contractors in Peterborough and Durham skip geotextile fabric, leading to settling and slab failures. Our reinforced base ensures permanent strength.
Stage 2: Precision Carpentry for Custom Designs
Our carpenters form patios, porches, steps, and walkways with millimeter accuracy.
- Custom shapes, curves, and design features.
- Structures built for both strength and aesthetics.
Why We’re Better: Many competitors use basic forms. We build customized layouts that enhance appearance and durability.
Stage 3: Reinforcement with Vinyl Rebar & Vapor Barriers
We use the most advanced reinforcement methods in Ontario.
- Vinyl rebar: 2.5X stronger than steel, corrosion-proof, and longer-lasting.
- Lightweight, high-strength reinforcement that ensures structural integrity for decades.
- Vapor barriers installed in moisture-prone areas to prevent slab curling, mold, and deterioration.
Why We’re Better: Most stamped concrete contractors in Peterborough and Durham ignore moisture barriers. We protect your slab from the ground up.
Stage 4 & 5: Concrete Placement & Finishing
We pour and finish concrete with precision methods designed for strength and appearance.
- Screeding for level surfaces.
- Magnesium float and steel trowel finishing for smooth, durable results.
- Custom stamping techniques for natural stone, slate, wood, or tile looks.
Why We’re Better: Our finishing prevents defects, reduces cracking, and ensures a professional appearance.
Stage 6: Structural Integrity & Final Touches
- Strategic relief cuts control expansion and prevent random cracking.
- Clean form removal for professional edges.
- Proper backfilling for long-term stability.
- Optional foundation anchors for added slab stability during freeze-thaw cycles.
Why We’re Better: Most companies ignore anchoring. Our slabs remain aligned and stable through Ontario’s toughest winters.
Stage 7: Protection & Sealing (Stamped Concrete Only)
We protect every stamped concrete surface in Peterborough and Durham with commercial-grade sealers.
- Deep cleaning and washing prior to sealing.
- Sealers that resist stains, salt, and weathering.
- Optional anti-slip coatings for safety around pools and walkways.
Why We’re Better: Standard sealers fade quickly. Our sealing system provides long-lasting color retention and protection.
Advanced Concrete Mixes for Maximum Durability
- 15+ years of testing with building science professionals.
- High-strength 35MPa mix with mono-poly fiber reinforcement.
- Vinyl rebar and optional embedded sensors for performance monitoring.
Why We’re Better: Many local contractors rely on standard mixes. Our engineered concrete delivers superior strength and longevity.
