01 / PRODUCT OVERVIEW

Small modules.
A bigger water strategy.

The module is the starting point. The system comes together through the right layout, envelope and supporting components.

PP modules form the core of an underground rainwater system. Depending on the surrounding envelope and hydraulic design, a module array may be configured for collection and storage, temporary attenuation or infiltration.

Start with the required volume, available footprint, installation depth and proposed surface use. These inputs help define the appropriate module layout and supply scope.

Modular layouts

Configure the array around the available footprint and required capacity.

Three system functions

Coordinate the envelope for storage, attenuation or infiltration.

A connected supply scope

Specify modules, liners, filters and inspection access together.

04 / INSTALLATION PLANNING

A clear plan.
Before work begins.

Coordinate each stage with the selected model’s installation instructions and the approved site design.

Read the planning guide
  1. 01

    Confirm the design

    Review ground conditions, loading, capacity and access.

  2. 02

    Prepare the base & envelope

    Follow the approved excavation, base and lining details.

  3. 03

    Assemble & connect

    Coordinate module assembly, pipework and inspection points.

  4. 04

    Inspect & complete

    Verify the system before approved backfill and surface work.

06 / YOUR QUESTIONS

Before you specify.

Clear answers for your next project conversation.

How do I select the right module?

Share your required volume, site layout, installation depth and surface use. These help establish the selected model and the documents needed for review.

Can the system be installed beneath traffic areas?

Suitability depends on the selected model, ground conditions, cover depth and structural design. Confirm the loading criteria and supporting test documentation before specifying.

What is the difference between storage and infiltration?

Storage normally uses a watertight envelope. Infiltration uses an interface appropriate to the surrounding ground. The final arrangement depends on the approved hydraulic and ground-condition assessment.

Can you supply the supporting components?

Discuss liners, geotextiles, filters, inspection access and connecting components as part of the project supply scope.

What should I send for a quotation?

Include your country, project drawings, required system function, volume if known, preferred colour and timing.
