Difficult Geometries & Ground Conditions

Difficult geometries and ground conditions for Commercial and Public Buildings

We understand that many construction sites may not be ideally suited to house standard volume underground water storage tanks which leads to space being taken up in the building rather than in the ground. However, our Rainstream tanks are constructed using Ridgistorm-XL large diameter pipe systems and can be fabricated to meet difficult site conditions and geometries.


By analysing site conditions and installation parameters, our system can be engineered to exact stiffness classifications so that it meets the required loading specification for a project without being over or under specified. Our design engineers can create a solution with the appropriate profile strength and stiffness classifications for each project, with pipe strength at varying stiffness between SN1-SN8


Ridgistorm-XL is designed to minimise the effects of ground movement, differential settlement and deformation. To minimise groundwater pollution, exceptional structural integrity is achieved with a minimal number of high quality joints.


We offer the only large diameter plastic pipe solution with integral electro-fusion jointing. This results in the whole pipe system effectively becoming a homogeneous unit. It’s available for 750 - 3000mm diameter pipes.
