ArmourFlow™ – Panel Drain

Armourflow protects waterproofing coatings and channels water efficiently to the drainage system, preventing hydrostatic pressure build-up.


Armourflow™ – advanced geocomposite drainage board. Protects waterproofing coatings and channels water efficiently to the drainage system, preventing hydrostatic pressure build-up. Armourflow ™ is comprised of a dimpled high crush resistant plastic core with a geotextile filter bonded to the core to provide a drainage sheet that can collect and filter water ingressing from backfill soils.

Armourflow™ can often be used to replace conventional mineral drainage aggregate and saves time and money due to its light weight structure and quick and easy installation without the need for heavy machinery.

Takatakahia Slip Repairs – Coromandel

11 Jun 2018

A large-scale storm event struck the Coromandel Peninsula late July 2017, leaving a trail of destruction in its wake. One location profoundly affected was SH25a where the Takatakahia stream embankment had suffered extensive scouring from rising water levels. The erosion significantly jeopardised the structural integrity of the state highway bridge above. NZTA deemed this as a high-risk situation as further erosion of the bank would cause the bridge to fail. Traffic management was deployed immediately following the storm; the affected lane of the road remained closed until the completion of construction.
