Silipell SP2: Smarter Concrete for Modern Infrastructure

Kuala Lumpur’s iN Design Lab will spotlight Silipell SP2 by Tech‑Dry through a new collaboration with Apong Stones, one of Malaysia’s fastest‑growing manufacturers of concrete ventilation blocks. This partnership highlights the Lab’s mission to connect cutting‑edge materials with forward‑thinking design practices.

Situated in KL Eco City, the iN Design Lab positions itself as Malaysia’s first and largest materials and design centre, spanning more than 30,000 square feet. The Lab promotes itself as a hub for interior design, architecture, and creative innovation. It curates resources and hosts regular events that encourage collaboration and networking among industry professionals.

Apong Stones: Driving Change in Ventilation Blocks

Apong Stones, founded in 2022, rapidly expanded to five factories nationwide. The company produces concrete ventilation blocks, which play a vital role in tropical architecture. Traditionally, manufacturers sold these blocks unsealed, forcing end users to apply water‑repellent sealers or paint. Yet in Malaysia’s humid climate, moisture ingress consistently undermines durability and aesthetics.

Now, Apong Stones integrates Tech‑Dry’s Silipell SP2 directly into production. As a result, the company delivers Malaysia’s first pre‑sealed concrete ventilation blocks. This breakthrough eliminates post‑installation sealing and significantly reduces long‑term maintenance costs.

Why Moisture Matters

Water penetration does more than damage appearances. It triggers fungal and algae growth, creates unsightly stains, and accelerates surface deterioration. Even when users apply traditional sealers, protection typically lasts only one to three years. Consequently, high‑rise buildings face costly, labour‑intensive maintenance cycles.

By embedding Silipell SP2 during manufacturing, Apong Stones provides a durable solution that resists moisture from the start.

What Makes Silipell SP2 Unique?

Silipell SP2 acts as an advanced water‑repellent admixture that bonds permanently within the concrete matrix. Unlike conventional sealers or admixtures, it cannot wash out, ensuring long‑lasting performance.

Key advantages include:

• Reduced water absorption and efflorescence: Protects surfaces against staining and weather‑related damage.
• Compatibility with multiple concrete forms: Performs effectively in precast, ready‑mix, mortar, and renders.
• No oily residue: Preserves the natural appearance of finished surfaces.
• Flexible dosing: Allows manufacturers to tailor water resistance by adjusting dosage rates.
• Easy integration: Fits seamlessly into existing concrete processes.

Sustainable Impact

Silipell SP2 not only strengthens concrete but also advances sustainability. Longer‑lasting structures require fewer repairs and replacements, which in turn reduces resource use and environmental impact throughout a building’s life cycle.

Concrete may serve as the backbone of modern infrastructure, but moisture ingress has long compromised its performance. By embedding advanced silicone nanotechnology directly into the mix, Silipell SP2 delivers lasting protection and sets a new benchmark for climate‑responsive building materials.
