The Standard Format

One Standard Size for Clear Project Planning

Before setting out the module field, confirm the standard HCR-1000 dimensions. Its fixed dimensions also help you plan site handling and delivery. At 82 mm deep, these stormwater storage modules suit projects with limited space below the surface.

System Principle

How Stormwater Storage Modules Work

HCR stormwater modules form a shallow layer below paving, planted areas or sports fields. Water enters the layer before flowing through its connected spaces. The system can then store the water, release it through an outlet or let it enter suitable ground.

Technical schematic · not to scale

This diagram illustrates the layer sequence. However, filtration, membranes, inlets, outlets and overflow arrangements depend on the required hydraulic function.
  1. Receive runoffInitially, water enters through the surface, drainage layers or inlet connections.
  2. Move water through the layerThen connected spaces allow water to move across the module field.
  3. Store or release waterFinally, the liner and outlet plan control where water stays and where it leaves the system.

HCR stormwater storage modules are one part of the stormwater management system. Therefore, the design also needs filters, the right base, suitable levels and a route for overflow. Together, these parts manage the expected runoff.

For example, a detention design holds runoff for a short time and then releases it at a controlled rate. In contrast, an infiltration design lets water pass into suitable ground. Alternatively, a retention design keeps water for its intended use. In each case, the liner, soil and outlet design determine the final function.

Module Delivery

Delivered Ready for Site Placement

We supply HCR-1000 as a factory-assembled module. As a result, your team has fewer parts to assemble on site. You can then move each unit into place and connect it to the next module.

Before delivery, agree the work sequence and mark the access, storage and unloading areas. For example, check that the unloading point connects to the planned placement route.

  1. Complete Stormwater Modules

    Before shipment, we join HOENSOEY Cells into complete HCR-1000 units.

  2. Packing and delivery

    After that, we protect the modules and secure them on pallets for delivery.

  3. Site preparation

    Then prepare the base and the specified geotextile or membrane on site.

  4. Alignment and connection

    Finally, place the modules tightly together and connect them. Also check the layout before adding the specified covering layers.

Internal Technology

HOENSOEY Cells Inside HCR-1000

HOENSOEY Cells form the inside of each HCR module, creating connected spaces for water. The six-sided components also have built-in connection points to hold them together.

The regular outer shape helps with handling and layout. Meanwhile, the open cell structure provides space for drainage and storage. In addition, the integrated connectors allow assembly without extra tools.

Cells test results apply to the tested component setup. Therefore, they do not set the load limit of a complete HCR installation. Ask for the relevant data so your engineer can check the finished system.

The 82 mm figure is the depth of one module. However, the total installation also needs space for the base, protection and surface layers. Request project technical data to review storage, loads and site needs.

Before counting stormwater storage modules, mark the boundaries, changes in level, access points and drain connections. Then confirm the usable area. As a result, you have a sound basis for checking the number of modules.

Typical Applications

Where to Use HCR Stormwater Modules

Stormwater storage modules can support several shallow drainage layouts. Before selecting a layout, review the intended use, available depth and loads. Then check the layers above and below the modules.

Sports Facilities

Sports Fields

Use shallow drainage modules to create storage space below a sports field. Also review the field layers, drain routes and outlet levels together.

Paved Infrastructure

Parking & Paved Areas

Add rainwater storage below a designed pavement system. In particular, your engineer must check vehicle loads, covering layers and the supporting ground before selecting the system.

Landscape Design

Landscape & Green Space

For example, use the modules within planted areas, plazas, tree zones or podium landscapes. Also check soil depth, roots, filters and structural loads as part of the design.

Runoff Management

Detention & Infiltration Areas

Use a shallow layer to hold, release or direct runoff. Therefore, the liner, soil conditions and outlets determine whether the system provides detention, retention or infiltration.

For each application, the project engineer must confirm the surface layers, loads, drainage capacity, membrane and outlets. However, these images show design concepts rather than completed project references.

Packing & Delivery

From Pallet Packing to Site Delivery

HCR-1000 can use 29 product layers per pallet. We then add stretch film, paperboard protection and green straps to secure the modules for delivery.

Before delivery, plan unloading around the pallet arrangement. Then unpack and move the modules to the prepared area in the order you intend to lay them.

In addition, include the destination port or site address when you request a supply proposal. Also tell us about access and unloading limits.

Project Configuration

HCR Accessories

Before choosing accessories, review the module layout and site needs. Then confirm their positions for installation.

HexConnector joins the layers in a stacked HCR arrangement and helps limit sideways movement. Therefore, check the connector positions and layer count before installation.

  1. Support the holder

    To begin with, place the holder flange on the geotextile at the planned position.

  2. Maintain water contact

    Then keep the white core in contact with the stored water below the holder.

  3. Provide a capillary path

    Finally, water can move along the core toward the planting medium through capillary action.

Also check the water level, wick contact and planting layers for the project. The diagram explains the path, but it does not specify a lift height or delivery rate.

Frequently Asked Questions

These answers cover the main product and site questions. For a more specific review, also send your project details.

Module format and installation

What are HCR stormwater modules?

HCR stormwater storage modules provide a shallow space for rainwater, with HOENSOEY Cells forming their internal structure. For example, the standard HCR-1000 model is the starting point for most initial layouts.

What are the HCR-1000 dimensions?

HCR-1000 measures 1000 × 1440 mm in plan and 82 mm in depth. However, the full system also needs space for the base, protection and surface layers.

Does HCR-1000 arrive assembled?

Yes, we deliver complete modules. Before placement, the site team prepares the base. Then the team places and connects the units. Finally, it adds the specified covering layers.

How do adjacent modules connect?

First, align and connect the modules tightly, following the project layout for edges, inlets and outlets. Then check each connection before adding the covering layers, leaving no deliberate gaps between modules.

Site design and delivery

Can HCR go below vehicle areas?

Your engineer may consider HCR within a designed pavement system. However, the review must cover traffic loads, surface layers and ground conditions. Therefore, Cells component tests alone do not establish traffic suitability.

Can HCR support both detention and infiltration?

Yes, if the engineer designs the complete system for that use. For example, detention holds water before a controlled release. In contrast, infiltration lets water enter suitable ground. Therefore, the membrane, soil and outlet plan determine the function.

How do you pack the modules?

HCR-1000 can use 29 layers per pallet, with wrap, paperboard protection and securing straps. For container loading, place tall pallets in one floor layer in a 40-foot high-cube container. However, final shipment details vary.

What information do you need for a proposal?

To begin with, send the location, intended use, area and delivery destination. Also add the surface layers, design loads and required depth or storage volume. Finally, attach drawings so we can check the layout and supply plan.
