Every outdoor renovation depends on the same fundamentals: correct excavation, proper base compaction, accurate grading, and drainage built for Toronto's clay soil and freeze-thaw winters. Darteno builds every project. From a single walkway to a full property renovation, on those fundamentals. That is what keeps interlock driveways, patios, and retaining walls performing for decades instead of settling within a few seasons.

• Interlock Driveways: Built for Toronto's freeze-thaw climate with proper excavation, compaction, and drainage.
• Patios: Interlock and natural stone patios designed for entertaining, relaxing, and year-round outdoor living.
• Landscaping: Sod, planting, garden beds, and grading that tie the whole property together.
• Retaining Walls: Engineered wall systems that level out slopes, control erosion, and create usable outdoor space.
• Drainage and Grading: French drains, catch basins, and grading corrections that eliminate pooling water and protect foundations.

Every project we build starts below the surface. We focus on excavation depth, granular base compaction, grading pitch, and drainage layout because those are the factors that determine how long the finished work lasts through Ontario winters. Whether the job is a small backyard patio or a full property renovation involving a driveway, retaining wall, and landscaping, every phase is managed to the same standard: a finished space that is structurally sound, properly drained, and built to perform in Canadian weather for decades.
