Renovation Synergy at Kuntai

From our 30,000sqm factory, we produce specialized "Low-Profile" planks and matching aluminum sub-frames designed for retrofit applications. We understand the unique constraints of renovation projects—such as door thresholds and existing drainage. Our US-patented decking provides the durability and thin-profile stability needed to make these transformations successful and long-lasting.

Residential & Commercial Renovations

  • Residential backyard patios and cracked concrete porches.
  • Commercial restaurant terraces with outdated stone or tile floors.
  • Hotel balcony upgrades where height is strictly limited.
  • Public plazas requiring a fast, non-invasive aesthetic refresh.

Retrofit Performance Benefits

  • Cost Savings: Avoids the high cost and mess of concrete removal and disposal.
  • Rapid Installation: A standard patio can be transformed in 1-2 days using simple tools.
  • Instant Aesthetic: Covers cracks and stains with a high-end, natural hardwood look.
Renovation VariableSelection Logic
Height RestrictionUltra-slim 18mm boards paired with 20mm aluminum joists.
Uneven SubstrateHeight-adjustable pedestals (10mm to 100mm) to create a perfectly level floor.
Drainage IntegrityOpen-joint or clip systems that allow water to reach existing drains beneath the deck.
  • Q: Will water get trapped under the new deck?
  • A: No, the system is designed to sit on joists or pedestals, creating an air gap that allows water to flow to existing drains and air to circulate.
  • Q: Can it handle a hot tub?
  • A: Yes, but the pedestals and joists beneath the hot tub must be spaced more closely to handle the concentrated weight.

Adjustable Pedestal & Clip Fixing

The most common method involves placing adjustable pedestals on the concrete, laying a joist grid, and then snapping the bamboo boards into place with hidden clips. This requires no drilling into the old concrete.

Precision Calibrated Thickness

Retrofit boards are precision-sanded to exact thicknesses (+/- 0.2mm) to ensure there are no "tripping hazards" or uneven joints in low-clearance installations.

Refined Renovation Aesthetics

Choose from "Sanded Caramel" for a warm traditional look or "Brushed Grey" to modernize an old space. The uniform color of our composite planks ensures the new floor looks cohesive and intentional.

Renovation Turnkey Solutions

We offer "Retrofit Kits" that include low-profile joists, boards, and fasteners, specifically curated for the most common residential patio sizes.
