Dincel Structural Walling

Dincel Structural Walling are stay-in-place polymer formwork panels that encapsulate a concrete wall. The panels can be used for load bearing and non-load bearing concrete walls for above or below ground applications. Unique patented snap-lock joints connect the panels together for fast and easy installation. This walling system is lightweight for greater safety and manoeuvrability on site.

Dincel requires no additional waterproof membrane when filled with ready mixed concrete. The flow and compaction of concrete is improved with Dincel Walls. Root causes of water problems such as porosity of walling material, leaking wall joints and wall cracks are eliminated.

The polymer skin will not melt away or contribute to the spread of fire. If the outside surface chars or burns, the core component remains as ordinary concrete. Dincel Structural Walling provides an effective barrier against external noise therefore creating a more comfortable living environment.

Limitations on Use

Dincel Construction System requires engineers, designers and installers to familiarise themselves with the Dincel Construction Manual for Designers and Builders (DCMDB).

The information contained in the DCMDB document is not intended to replace design calculations or analysis normally associated with the design and specification of buildings and their components.

Building professionals are required to assess construction site conditions and provide design /details and appropriate safe work methods accordingly.

The installers must require specific project specific detailing for each and every project. (Refer to Section (C) of Dincel Construction Manual for Designers and Builders).
