Terraform Construction Ltd. | Professional Hardscaping & Outdoor Living Design

Most patio projects are completed within 3 to 7 business days. This timeline includes site excavation, foundation preparation, and the final laying of materials, though it may vary based on the project scale and site accessibility. 

No, while both are outdoor living spaces, patios are built directly on the ground using stone or concrete, making them ideal for level surfaces. Decks are raised platforms typically made of wood or composite, which are better suited for sloped yards or uneven terrain. 

The average cost of patio installation in the Lower Mainland typically ranges from $15 to $35 per square foot. Total pricing depends on your choice of materials—such as interlocking pavers, natural flagstone, or stamped concrete—as well as the complexity of the site preparation and drainage requirements. At Terraform Construction Ltd., we provide transparent, line-item landscaping estimates to help you budget for your high-end outdoor renovation. 

In most cases, a ground-level paver patio installation does not require a building permit in municipalities like Richmond, Burnaby, or Surrey. However, if your design includes a raised deck, a retaining wall over 1.2 meters, or significant changes to your property’s drainage plan, a permit may be necessary. We ensure all our hardscape designs comply with local BC building codes and municipal bylaws. 

Proper surface grading is the most critical factor for patio drainage in Vancouver. We ensure every patio is sloped at a minimum 2% grade to direct stormwater runoff away from your home’s foundation. For yards with high water tables, we integrate French drains, catch basins, or permeable pavers to prevent pooling and protect your landscape from erosion. 

We prevent weed growth by using high-performance polymeric sand to fill the joints between your patio stones. When activated with water, this sand hardens into a powerful barrier that resists insects and prevents seeds from taking root. When combined with a professional-grade weed barrier during the base installation, your patio will remain clean and virtually maintenance-free. 

Yes, we can perform a paver overlay if your existing concrete patio is structurally sound and free of major settling. This method allows you to upgrade to the look of natural stone or modern pavers without the cost of a full demolition. Our team will assess your concrete’s integrity and height clearances to ensure a safe and level hardscape renovation. 

To maintain your hardscape investment, we recommend a simple routine of sweeping and occasional rinsing. Applying a professional paver sealer every 3 to 5 years will protect the surface from UV fading, oil stains, and moisture penetration. For natural stone patios, periodic cleaning prevents the buildup of moss and algae common in the damp Lower Mainland environment.
