DAK-STORM THE STORMWATER SYSTEM

DAK-Storm is a highly efficient, underground modular system for stormwater management in urban, residential, and infrastructure settings. Manufactured from high-strength injection-moulded polypropylene (PP) drainage blocks, it creates vast subterranean reservoirs for water storage, lamination (attenuation)*, or dispersion. By holding large volumes of rainwater below ground, DAK-Storm frees up valuable surface space while mitigating flood risk, recharging natural aquifers, and enabling water reuse — transforming a potential liability into a sustainable asset for modern cities.

*Lamination (attenuation) is a storm water management technique where excess rainwater is temporarily held in underground reservoirs and then discharged at a controlled, gradual rate. This delays the rush of water into sewers and waterways, smoothing out storm surges and protecting surrounding areas from flooding - turning a sudden downpour into a manageable, slow-release process.

Why choose DAK-Storm

  • Maximum volume efficiency — greater storage capacity in a smaller footprint;
  • Certified strength — uncompromising structural integrity;
  • Fully modular — adaptable to any project requirement;
  • Smart logistics — streamlined from warehouse to site;
  • Easy inspection and maintenance — ensuring long-term performance;
  • Eco-compatible — 100% recyclable materials.
