Plastream® pipe finds new niche as underground air-con ducting


The unique properties of Rocla Plastream® steel-reinforced polyethylene drainage pipe have seen it used in a number of applications for underground air-conditioning ducting.

Meinhardt recently specified Plastream® pipes at the redevelopment of the RACV Country Club at Healesville in Victoria. The redevelopment by Abigroup will add 80 rooms of accommodation over four levels, multi-storey carpark, dining, lounge and function areas, golf support facilities, refurbishment works to existing building, swimming pool, day spas and landscaping.

The pipes were used for the in-ground works of the swimming pool, to supply conditioned air to the perimeter pool floor outlets. The floor outlets direct air internally up against the perimeter glass walls to prevent fogging.

The pipe was chosen because its smooth interior provides low airflow resistance, and its inherent strength, which resists crushing in underground applications. Some 200 metres were laid in a rectangle with 40 spigots as vents. The pipes are laid with normal drainage falls so that residual water can run back to a drainage sump/pump.

Plastream® drainage pipe is the strongest long-term plastic pipe product available and combines the advantages of a smooth PE bore with the structural strength of steel.

The steel reinforcement is fully encapsulated within the UV-stabilised polyethylene pipe wall, allowing the manufacture of robust, lightweight pipes with high stiffness. Further advantages include light weight and resistance to creep.
