Infiltration tank benefits

concrete tank benefits.

Unique design – made with angled hole inserts, our infiltration tanks allow for continuous outward draining of grey water.

Easy installation – each panel is designed in a way that allows for simple and straightforward installation.

Made with retrofitting in mind – should the need for increased holding capacity arise, additional tanks can be installed at a later stage due to their modular nature.

Exceptional strength – the integral strength of each panel has been tested against industrial concrete standards to maintain a minimum of 40 Mpa compressive strength. This means our tanks are strong enough to withstand the weight of a 2 tonne truck!

Consistency – using specially designed spacers (during manufacture) that ensure our wire mesh grids are kept exactly midway in the moulds, our panels provide consistent quality.

MANY PURPOSES, MANY BENEFITS:

Made to order – we can manufacture tanks according to engineer, architect or municipal specification.

Modular design – tank holding capacity can be modified by adding or removing panels.

Versatile – with small panel changes, the tanks can be modified to suit different applications. For example, positioning the centre panel and exit panel 160mm holes at the bottom of the tank allows for a stormwater attenuation tank, whereas positioning them at the top allows for a mini concrete septic tank or grease & fat tank.

Municipal Covers

We are able to manufacture customised manhole covers that are suited to municipal use. Our customisations include adding municipal logos and names on our specially-designed cover rings as well as unique colours. The colour of these rings can be matched with each municipality to ensure easy identification and, therefore, deter theft. The plastic rings also prolong the lifespan of the manhole lids, as they act as a buffer and reduce concrete chipping upon removal and insertion of the covers.
