Outdoor Decking FAQ
What is HPCT WPC Outdoor Decking?
HPCT WPC stands for Hollow PolyLux Composite Technology – Wood Plastic Composite. It’s an advanced outdoor decking material made by combining recycled wood fibers with high-performance polymers, creating a strong, durable, and eco-friendly product.
Compared to traditional timber, HPCT WPC decking is:
- Weather-resistant – no warping, cracking, or rotting
- Low-maintenance – no need for regular sealing or painting
- Termite & mold resistant – ideal for Singapore’s humid climate
Its hollow core design also improves heat dissipation and reduces footstep noise, making it a smarter, more comfortable choice for modern outdoor spaces like balconies, patios, and pool decks.
How does HPCT WPC Outdoor Decking compare to traditional wood decking?
While HPCT WPC Outdoor Decking is a composite material, it offers major advantages over natural wood—especially for outdoor use in Singapore’s hot and humid climate.
- Eco-friendly – Made from recycled wood fibers and polymers, making it a greener, more sustainable choice.
- Highly durable – Resistant to water, termites, rot, and UV damage. It won’t crack, warp, or splinter like natural timber.
- Low maintenance – No need for sanding, staining, or varnishing. Just occasional cleaning with water is enough to keep it looking great.
- Long-lasting colour and appearance – Engineered to maintain its colour and surface integrity over time, without fading or peeling.
In short, HPCT WPC decking gives you the look of wood without the hassle—perfect for balconies, patios, and any outdoor space.
What is the lifespan of HPCT WPC Outdoor Decking?
Traditional wooden decking typically lasts around 10 to 15 years, depending on maintenance and exposure to the elements. In comparison, HPCT WPC Outdoor Decking is built to last much longer—25 to 30 years or more with proper care.
Thanks to its resistance to weather, termites, moisture, and rot, it maintains structural integrity and appearance over time. This extended lifespan makes HPCT WPC a durable, long-term investment and a more cost-effective solution than natural wood for outdoor spaces like balconies, patios, and terraces.
Can I level up the outdoor decking at my balcony to match the living room floor height?
Yes, absolutely. At DeckTech, we specialize in both supplying and installing custom outdoor decking systems that can be elevated to match your indoor flooring height.
Our team uses a strong, waterproof substructure system to safely raise your balcony floor—ensuring it’s stable, durable, and built to last. The result is a seamless, step-free transition between your living room and outdoor space, enhancing both the aesthetics and practical flow of your home.
How should HPCT WPC Outdoor Decking be cleaned and maintained?
HPCT WPC decking is low-maintenance, but regular cleaning will help it look its best and last even longer.
- Sweep or mop regularly to remove dust, dirt, and debris.
- For deeper cleaning, you can use a pressure washer—just keep the pressure below 1500 psi and hold the nozzle at a safe distance to avoid surface damage.
- To clear debris between the decking gaps, use a plastic spatula or non-metal gardening tool. Avoid sharp metal objects like rakes or shovels, which may scratch the surface.
- For long-term protection, especially in areas with strong sunlight, we recommend adding an awning or UV screen to minimize direct exposure and extend colour retention.
With basic care, your decking will stay beautiful and functional for decades.
Is composite decking slippery when wet?
Our HPCT WPC decking is designed with textured surface finishes that improve grip and reduce the risk of slipping—even in wet conditions. It offers a safer alternative to traditional wood, which can become slippery when exposed to rain or water.
- Slip-resistant texture – safer to walk on when wet
- Ideal for balconies, pool decks, and patios
- Low-maintenance safety – no need for additional anti-slip coatings
This makes it a smart and practical choice for any outdoor area exposed to moisture or frequent rain.
Why do some sellers say composite decking attracts mold and mildew?
This concern often comes from older or poorly installed decking systems. Mold and mildew don’t grow on the composite material itself—they form on trapped moisture, dirt, or organic debris if the area is not well-maintained.
At DeckTech, we prevent this with the right materials and professional installation:
- High-quality WPC decking – built to resist mold, mildew, and insects
- Proper slope and ventilation – ensures water drains and air flows easily
- Easy-to-clean surfaces – textured and low-porous to prevent build-up
With the right care and DeckTech’s expert installation, your decking stays clean, dry, and hassle-free—even in Singapore’s humid weather.
Do dirt and water get trapped under the decking?
Over time, it’s normal for some dust, leaves, or rainwater to collect beneath outdoor decking. At DeckTech, we design our decks with smart drainage in mind:
- Built-in drainage gaps allow rainwater to flow through easily
- A sloped subframe system directs water toward the nearest floor trap
- An openable access panel is included near the drainage point for easy maintenance
This ensures any trapped debris can be cleaned without dismantling the entire decking—keeping your space clean, functional, and low-maintenance.
How does HPCT WPC decking perform in Singapore's hot and humid climate?
Our HPCT WPC decking is specially engineered to handle Singapore’s tropical weather. It performs reliably under intense heat, high humidity, and frequent rain—perfect for outdoor spaces across HDBs, condos, and landed homes.
- Heat-resistant – stays cooler under direct sun exposure
- Moisture-resistant – won’t warp, swell, or rot in humidity
- UV-stable – resists fading and maintains its appearance over time
Its durable design ensures long-lasting performance and comfort, even in Singapore’s toughest outdoor conditions.
Is HPCT WPC decking fire-resistant?
At DeckTech, our HPCT WPC decking is built with enhanced fire-retardant properties, making it a safer choice for residential outdoor use especially in areas with heat sources like BBQ pits or open balconies.
- Resists flame spread – slows ignition and limits fire expansion
- Complies with fire safety standards – tested for safe outdoor residential use
- Ideal for balconies and BBQ corners – added safety where it matters most
With these built-in features, our decking offers extra peace of mind for homes, patios, and high-rise living spaces.
Is HPCT WPC decking safe and environmentally friendly?
Yes. Our HPCT WPC decking is designed to be safe for both people and the planet. It’s a reliable choice for families, pets, and eco-conscious homeowners.
- Non-toxic and safe – free from harmful chemicals like formaldehyde and heavy metals
- Eco-friendly composition – made with recycled wood materials to reduce waste
- Low environmental impact – longer lifespan and less maintenance compared to natural wood
Whether for a home, balcony, or commercial space, our decking combines safety, durability, and sustainability in one smart solution.
Can I install HPCT WPC Outdoor Decking myself, or should I hire a professional?
While DIY installation is possible for small areas, choosing professional installation by DeckTech ensures a safe, durable, and polished result—especially for larger or elevated spaces.
Here’s why homeowners prefer our expert team:
- Precise installation – ensures proper leveling, spacing, and alignment
- Compliance with local codes – especially important for condos, balconies, and raised subframes
- Cleaner finishing – with custom cuts, seamless transitions, and concealed fastenings
With DeckTech’s skilled installers, you get more than just decking—you get peace of mind and long-term value.
Can composite decking be installed directly on the ground?
While HPCT WPC composite decking is resistant to rot, moisture, and termites, direct ground installation is not recommended for long-term performance.
For best results, we always install the decking on a raised subframe system (using WPC, Balau wood, or aluminium) to ensure:
- Proper ventilation
- Effective water drainage
- Longer lifespan and structural integrity
This method prevents moisture build-up and ensures your decking stays strong, safe, and beautiful for years—even in wet or shaded areas.
What subframe materials are available for outdoor decking?
At DeckTech, we offer three types of subframe materials for outdoor decking installation, depending on your budget, usage, and site condition:



X-Frame WPC Subframe –
A cost-effective and weather-resistant option made from Wood-Plastic Composite. Suitable for most standard residential balconies with light to moderate usage.
Balau Wood Frame –
A traditional solid hardwood frame with good strength and load-bearing capacity. Recommended for clients who prefer a natural material or heavier installations.
Aluminium Frame –
The most durable and long-lasting option. Rust-proof, termite-proof, and highly stable—ideal for long-term use, wet areas, or premium projects.
Is the decking around the balcony drainage accessible for cleaning?
Yes. At DeckTech, we design our balcony decking systems with convenience in mind. To make maintenance easy, we include:
- An openable panel at the drainage floor trap area for easy access
- Simple debris removal without needing to dismantle the decking
- Long-term functionality with a clean and clear drainage flow
This smart feature is built into every installation to ensure your balcony stays clean, practical, and hassle-free.
How long is your warranty for HPCT WPC Outdoor Decking?
At DeckTech, we back our HPCT WPC decking with long-lasting protection for both materials and workmanship:
- 20-year product warranty – covers the durability and performance of the decking boards
- 12-year workmanship warranty – ensures quality installation and long-term satisfaction
This dual warranty gives you peace of mind, knowing your outdoor space is protected by both strong materials and expert craftsmanship.
Some sellers say Hollow WPC Outdoor Decking is not strong and can’t support heavy furniture. Is that true?
This is a common misconception.
DeckTech’s HPCT Hollow WPC Outdoor Decking uses the latest-generation composite technology with internal support chambers that distribute weight evenly—making it strong enough to handle:
- Heavy furniture
- BBQ pits
- Large planters
In comparison, older solid WPC decking tends to retain more heat and may crack, warp, or expand under direct sun, especially without ventilation.
We still offer solid WPC decking upon request, but for most modern homes, hollow HPCT WPC offers better cooling, lower noise, and stronger performance.
At DeckTech, we ensure strength not just through materials, but through proper engineering and expert installation—for long-lasting safety and peace of mind.
