Frequently asked questions

Common technical and specification questions for Deck Modular.

• How does this differ from the standard Plycem Deck plank product?+

  Plycem Deck (plank) is a 150×3657mm long-grain plank fastened to joists with hidden clips — a permanent fiber-cement plank-deck system. Deck Modular is a 300×300mm tile that interlocks without fasteners — ideal when you need a removable surface (rooftop terrace where you may need under-floor access) or a fast-install pattern floor over an existing flat surface like a concrete slab. Both share ASTM C1186 fiber-cement durability.

• Do I need adhesive or fasteners to install Deck Modular tiles?+

  No. The interlocking edge engages adjacent tiles mechanically; the assembly is held in place by its own weight (9.21 kg per tile) and the perimeter constraints of the deck area. For high-wind rooftop installations or pool surrounds, perimeter edge fixing or weighted border tiles are recommended — consult our technical team for the specific anchoring detail.

• Can I remove individual tiles for under-deck access?+

  Yes — that is a key advantage of the modular system. Individual tiles can be lifted to access waterproofing membranes, drains, or services below. This makes Deck Modular well-suited for rooftop terraces above occupied spaces where maintenance access matters, where a permanent plank deck would require destructive removal.

• How does fiber-cement modular compare to plastic interlocking deck tiles?+

  Plastic modular tiles (Trex, IKEA Runnen, polypropylene grids, etc.) are lighter and cheaper but degrade under UV exposure and do not carry the load or long-term weather resistance of fiber-cement. Plycem Deck Modular delivers wood-look or graphite aesthetics with the long-term durability of cementitious material — will not warp, soften, or fade like polymer tiles.
