Deep Large Wave Textured Exterior Bamboo Decking

Waterproof Weatherproof Floor For Garden, Poolside & Balcony

Product Overview

Deep large wave textured exterior bamboo decking is engineered for outdoor environments requiring superior water drainage and slip resistance. The manufacturing process combines strand woven bamboo technology with deep wave texturing. The wave profile features 6mm depth and 10mm width with a pronounced sinusoidal curve across the board surface. This deep wave geometry provides traction in wet conditions while channeling water away from the walking surface. Material density ranges from 1.15 g/cm³ to 1.25 g/cm³. Carbonization at 180-200°C removes organic compounds and reduces moisture content to 8-12%. The deep wave texture creates a three-dimensional surface that enhances water runoff and debris evacuation. This decking is specifically developed for garden pathways, poolside areas, balcony installations, and exterior spaces requiring high slip resistance.

Core Properties

01

Deep Wave Texturing

Deep wave profile with 6mm depth and 10mm width creates a three-dimensional surface that channels water away from the walking surface. The pronounced sinusoidal curve provides multi-directional slip resistance in wet and dry conditions.

02

Waterproof Performance

Strand woven construction with phenolic resin saturation provides water resistance. Carbonization at 180-200°C reduces equilibrium moisture content to 8-12%, limiting water absorption and dimensional movement.

03

Weatherproof Durability

Material density of 1.15-1.25 g/cm³ and Janka hardness exceeding 3,000 lbf provide resistance to mechanical wear and environmental degradation. The carbonized structure resists decay organisms and UV exposure.

04

Water Drainage System

The deep wave geometry creates channels that direct water flow along the board length. The wave pattern prevents standing water accumulation and reduces slip hazards on exterior surfaces.

FAQ

Frequently Asked Questions

▶ How does the deep wave texture improve slip resistance compared to other profiles? +

The deep wave texture with 6mm depth and 10mm width creates a three-dimensional surface that provides traction in multiple directions. Unlike straight grooves that only offer grip along a single axis, the sinusoidal wave pattern distributes friction forces across both longitudinal and lateral planes. Testing under ASTM D2394 shows wet coefficient of friction values exceeding 0.75. The deep wave geometry also channels water away from the contact area through capillary action, reducing the water film thickness on the walking surface. This design is particularly effective in poolside and garden environments where continuous water exposure is present.

▶ What makes this decking waterproof and weatherproof for outdoor use? +

The waterproof performance is achieved through three mechanisms. First, the strand woven construction with phenolic resin saturation creates a composite structure with reduced porosity. Second, carbonization at 180-200°C removes organic compounds and reduces equilibrium moisture content to 8-12%, limiting water absorption. Third, the high material density of 1.15-1.25 g/cm³ provides a barrier against moisture penetration. Weatherproof performance is maintained through the carbonized structure that resists fungal decay and dimensional movement across temperature and humidity variations. The deep wave geometry also facilitates rapid water drainage, preventing prolonged water exposure.

▶ How does the deep wave profile affect cleaning and maintenance? +

The deep wave profile with 10mm width allows for effective cleaning using standard deck brushes or pressure washing equipment. The wave geometry prevents debris accumulation in narrow crevices, as the wide channels allow dirt and leaves to be easily removed. Regular cleaning with a soft-bristle brush and neutral pH detergent removes surface deposits. Pressure washing at 5-7 MPa with 300mm standoff distance is recommended for deep cleaning. The deep wave pattern maintains its slip resistance properties after cleaning without requiring special treatments or coatings. Application of water-based outdoor oil every 12-24 months preserves surface appearance and water repellency.

▶ Is this decking suitable for installation over existing surfaces? +

Yes, the decking can be installed over existing surfaces using elevated pedestal systems or sleepers that provide ventilation and drainage. A minimum 20mm air gap must be maintained between the decking and substrate to allow for moisture evaporation. The pedestal system should provide adequate slope for water drainage. Joist spacing of 400mm maximum centers applies for standard thickness boards. Stainless steel fasteners are required for all installations to prevent corrosion in wet environments. Pre-drilling is recommended for all fastener locations to prevent splitting. Expansion gaps of 5-6mm between board ends and 3-4mm between board edges are required for thermal movement.
