Off-Form concrete formwork is one of the most commonly used materials for load bearing and non-load bearing functions in construction. As a cost-effective building solution off-form concrete can be found in nearly every building structure throughout Australia.
The way concrete is created from a mix of materials, then applied via pouring or spreading gives rise to an almost limitless range of forms and finishes.
One of the most common ways to install concrete is using off-form or poured in place concrete. For walls and decorative surfaces, the quality of the formwork for the off-form concrete determines the resulting look of the concrete surface.
Aside from thorough planning and design, the formwork which forms a mould for the off-form concrete to be poured into, is critical to the quality of the off-form concrete finish.
For complicated off-form concrete designs where precision is required timber formwork is the most versatile of the different types of formwork available. Others include engineered or concrete formwork.
The team at LF Construction Services have over 10 years experience constructing timber formwork specifically for off-form concrete. For a residential project designed by Chanine Design Architects in Strathfield, Liam and his team were called in to do the off-form concrete formwork for the concrete walls.
The first stage of the formwork is to assemble the steel structure and prepare the timber surfaces for the off-form concrete mould.
The timber formwork must be designed to support the loads from placing and compaction of the off-form concrete during pouring.
All the joinery has to be as straight and true as possible, making sure to mitre all the formwork joins and use the appropriate fasteners so that the resulting off-form concrete comes out as designed.

The big pour day. Concrete is piped into the top of the off-form concrete formwork very carefully section by section followed by a vibrator to compact the off-form concrete. Any mistakes in the formwork could lead to a catastrophic blowout at this stage.
For this project LF Construction Services worked closely with EKC Construction on the off-form concrete pour. Paul Corbett and his team at EKC Construction are well known in the industry for their high quality workmanship and expertly managed projects.
The resulting smooth off-form concrete walls showcase the quality off-form concrete formwork of LF Construction Services and the professional workmanship of EKC Construction.
