Modular Drainage System

The Rosehill Rail Modular Drainage System (MDS) revolutionises rail drainage by replacing traditional perforated pipes and concrete systems with an innovative, sustainable solution.

Manufactured from recycled rubber and featuring 45% void space, the system ensures sustained high permeability across its entire installation.

Modular Drainage System Overview

The Modular Drainage System (MDS) is a replacement for perforated pipe and/or perforated concrete within track drainage.

It provides sustained high permeability across its entire installation due to its 45% void space, effectively reducing and preventing surface and trapped water within the track ballast and formation.

Unlike perforated pipes and channels, which are prone to blockages and structural failures, the increased resilience and permanent voids within the MDS material and its structure significantly de-risks failure modes associated with poor or minimal maintenance, providing mitigation against the rapid deterioration and premature end of service life for rail assets.

Additionally, the MDS will self-correct installation misalignments, ensuring consistent, long-lasting drainage performance.
