HOENSOEY Cells Ultra-Shallow Honeycomb Stormwater Modules for Heavy Duty Drainage Applications

HOENSOEY Stormwater Modules, Novel Shallow Drainage Cells

HOENSOEY Drainage Cells are novel stormwater modules designed for shallow water treatment. Noted for their ultra-high compressive strength and unique connection buckles, these rainwater storage honeycomb units play an integral role in shallow surface water treatment processes.

Ultra-Shallow Rainwater Storage Honeycomb Units: Heavy Duty Drainage Cells

HOENSOEY Cells - the Vertical Loading 80 tons/sqm

The Vertical Loading 80 tons/sqm

Boasting an ultra-high compressive strength, these honeycomb units can withstand a vertical loading of up to 130 Tons/sqm and a lateral loading of 40 Tons/sqm. These figures are backed by reputable testing institutions, ensuring that you're investing in a reliable product.

Incorporating heavy-duty drainage needs, HOENSOEY Cells Water Storage Crates offer a remarkable void ratio of around 95% for the water processing process, facilitating effective and rapid drainage even under heavy rainfall or high water flow conditions.

 A Void Ratio of 95 percent

Designed with a stable mechanical honeycomb structure, the hollow interiors contribute to an impressive 95% void ratio. This ensures optimized water flow efficiency amongst the modules, catering to efficient drainage needs.

HOENSOEY Cells stormwater module have Six unique patented buckles are attached to each other.

Six Sets of Unique Buckles

Each stormwater module is equipped with six unique buckles, facilitating a secure connection between units. This design not only guarantees that the modules remain firmly interlocked but also simplifies and accelerates the installation process.

Innovative Sustainable Shallow Stormwater Management System

HOENSOEY Drainage Cells are, in fact, a type of underground drainage and stormwater management system. They consist of modular plastic units, usually with a honeycomb-like structure, designed to support high surface loads. These modules can be assembled into underground storage and heavy-duty drainage systems.

HOENSOEY Cells serve several main purposes in urban and infrastructure projects:

  1. Effective Stormwater Management: Harnessing the prowess of HOENSOEY Cells ensures that rainwater is channeled into the underground system, deftly curtailing surface runoff and drastically diminishing flooding episodes.
  2. Strategic Underground Drainage: The HOENSOEY Drainage Cells fabricate an intricate subterranean drainage web, acting as a bulwark against escalating groundwater levels and staving off undesirable water ponding.
  3. Groundwater Recharge Enhancement: In apt settings, HOENSOEY Cells champion the gradual seepage of rainwater into the earth, fortifying groundwater recharge endeavors.
  4. Unwavering Commitment to Environmental Stewardship: The judicious management of rain and groundwater by our systems is a testament to our dedication to conserving local ecosystems and preserving water assets.


Owing to their modular construct and seamless installation capabilities, HOENSOEY Cells have garnered significant traction in engineering ventures. Their design and assembly can be adeptly tailored to meet the unique demands of individual projects and the intricacies of varied terrains.

The HOENSOEY stormwater modules are made from high-strength PP. With an estimated life of up to 50 years, they are a perfect alternative to traditional sub-base materials.

Features of HOENSOEY Cells

The HOENSOEY stormwater modules stand out as a premier solution tailored for rigorous drainage needs. Fabricated from high-durability PP material, these modules boast a commendable lifespan of approximately 50 years, positioning them as a superior alternative to conventional sub-base materials. Their distinct honeycomb design ensures unwavering structural stability, while the expansive geocellular storage tanks excel in rainwater retention, detention, and robust drainage. A defining advantage is the system's shallow profile, which mitigates construction disruption to the terrain. As a result, project managers can anticipate savings of up to 30% on site drainage expenditures in contrast to traditional approaches.
