Dincel World’s First Warranted Waterproof Structural Wall


16 March 2018

Dincel: Dincel Structural Walling is Australia’s first polymer-based permanent formwork system and the company’s Chairman, Burak Dincel, said that once the product’s formwork is filled with concrete it is completely waterproof.


Patented innovative ring form allows minimum 180mm (maximum 230mm) concrete slump in a single pour up to 4.5 metres







Patented Dincel barbs and cement slurry ensures that snap joint is waterproof







180mm minimum concrete slurry improves concrete flow and compaction and eliminates the possibility of air voids







275mm Dincel











“Our polymer skin is impervious to water and once concrete filled, the Dincel panel joints are completely waterproof. Naturally, the junction between Dincel Wall and the footing/slab requires waterproofing, but there is no need for the use of additional waterproofing measures such as a membrane at the wall surface. Our Dincel construction manual outlines various methods to control water penetration between the Dincel wall and footing/slab junction,” said Mr Dincel.

“Dispensing with a waterproofing membrane affords considerable time and cost savings and also eliminates works in confined spaces such as between the wall and excavated soil surface, thus improving site safety compared with traditional building methods.

“Dincel is completely waterproof because its stops water ingress at the wall surface. It eliminates the root cause of defects such as concrete cancer, steel corrosion, leaking and mould.

The polymer skin encases the concrete to create a waterproof load-bearing permanent structural wall.

Mr Dincel said building structural walls using porous materials such as composite boards and sheeting, concrete blocks and in-situ or precast concrete can easily result in rainwater or moisture absorption and cracking, which spawns a chain-reaction that can lead to expensive and prolonged rectification works. The problems at basement walls below ground levels are well known to the industry.

“These are commonplace problems any builder or asset owner should and can now easily avoid,” he said.

“It helps to understand that concrete can only be waterproof if its crack widths are less than 0.1 millimetres. Unfortunately, the science of expansion and contraction dictates that cracking in exposed conventional concrete or block walls is unavoidable, hence the requirement of waterproofing membranes.

“However, if a waterproofing membrane fails – as is too commonly the case – its repair or replacement is required. In order to waterproof the concrete, locating the leak is required, which is virtually impossible. This has widespread and long-term implications for the building industry and property owners.”


The secret to the Dincel Wall system is that its concrete core is entirely encapsulated by the non-porous outer polymer layer, which also prevents cement leakage. The latest Dincel innovation, the 275mm profile takes this unique waterproofing technology to the next level with its patented innovative ring form which allows a minimum 180mm (maximum 230 mm) concrete slump in a single continuous pour – for up to 4.5 metres.

Achieving 4.5 metre heights in a single pour with 200 mm slump concrete is currently unheard of in the Australian market (or are known to be associated with very expensive and elaborate conventional formwork systems). Dincel 275mm delivers this innovation in a cost efficient, light-weight formwork system which significantly increases construction speed and safety on-site.

The patented barbs at the joint lock tightly together and are tighter still under the tension of the concrete pour and subsequent curing. The gap between each panel connection leaves no room for aggregate to land and create air gaps in the pour. Instead, high-flow concrete slurry fills in around each panel joint, bonding them together and sealing the joint connection to complete a monolithic fill. The high-flow cement slurry without the presence of aggregates seals each barb joint to achieve complete waterproofing at the panel joints.

Dincel’s new 275mm profile achieves waterproofing at each panel joint having the following combination

“The concrete encapsulated within the stay-in-place Dincel formwork delivers a significantly increased hydration period, thus denser and stronger concrete – both in tension and compression. No air voids or honeycombing can occur when high-slump concrete is used,” he said.

Another performance feature in the system is natural crack inducement. The unique design creates controlled cracks via inducers which pre-empt tolerably small crack widths, and avoid larger cracks through movement. Such tiny cracks are subsequently healed via the concrete’s natural autogenous process, resulting in a virtually crackfree wall impregnable by water. This dispenses with the need for horizontal steel wall reinforcement usually deployed for crack control.

Dincel has conclusive CSIRO testing which states the 200mm Dincel Wall is waterproof at the panel joints under 6m head of water pressure, all without the use of a waterproof membrane. The new 275mm Dincel delivers superior performance due to its innovative ring formation, allowing up to 230mm slump concrete which is key to achieving waterproofing at the panel joints.

“Because of its integrity, Dincel Structural Walling is maintenance free - delivering an expected lifecycle of at least 100 years – which is attractive from an environmental sustainability perspective, and of course a huge advantage for building owners.”

Dincel’s qualified engineers and certified installers offer the convenience and surety of a single source supply, technical support and compliance.
