Self compacting concrete


Topflow is a self compacting free flowing concrete.

While conventional compacted concrete has its limitations with placement often requiring considerable manpower, machinery and time, Topflow self compacting concrete provides a cost effective and efficient solution.

Free flowing Topflow is the ultimate self compacting concrete. It can be poured quickly and spread effortlessly into any type of formwork to provide an exceptional, highly aesthetic finish. It’s not just time and money that can be saved, this quick pour concrete reduces noise and eliminates vibration, considerably improving conditions on site.

Topflow comes in several different variants which includes Topflow Horizontal, Topflow Concrete, Topflow Architectural, Topflow Precast and Topflow Trenchflow.

Topflow has fluidity and stability that delivers the ultimate free-flowing, self-compacting concrete.

Topflow can be waterproof, coloured and have fibres or other performance enhancing additives added during production.

Why use Topflow?

Additional info

Topflow can be poured quickly, is free-flowing and can spread effortlessly to provide an exceptional, highly aesthetic finish. Topflow comes in several different variants which includes Topflow Architectural, Topflow Horizontal, Topflow Precast, Topflow Concrete and Topflow Trenchflow.

Topflow Architectural provides exceptional quality on vertical applications. Omit with no remedial work. The Topflow mix is specified and designed for each project. Placing techniques and strength can also be tailored to suit project requirements. Topflow Architectural uses advanced technology for the highest surface quality. The high fluidity of this concrete mix replicates the shape and texture of formwork to match complex design applications.

Topflow Concrete is designed to flow easily through congested heavily reinforced areas. It meets the demands of all construction types. Topflow Concrete is self-compacting and can be used in all mass fill concrete foundation applications. This free-flowing concrete is also available in eco mixes.

Topflow Trenchflow reduces labour overheads, permitting the flexible use of labour onsite. Delivered in highly fluid form with high deformability, Topflow Trenchflow allows quick changes of direction and easy flow around the foundation trench. This self-compacting concrete is ideal for use in all mass fill concrete foundation applications. Topflow Trenchflow can be formulated to meet up to DC-3 sulphate resistance classification. Eco mixes are also available.

Topflow Horizontal enables the rapid and effortless construction of slabs and floors. With high finishing characteristics, surface quality eliminates the use of power floating. Floor finish tolerance to BS 8204-1 SR2

Topflow Precast concrete has been specifically developed to suit the demands of precasting. This bespoke solution can be tailored to individual requirements. Using advanced technology, this precast concrete solution has the highest surface quality. High early strength and high final strength versions are available.
