A suspended floor construction refers to a floor slab where its perimeter is, or at least two of its opposite edges are, supported on walls, beams or columns that carry their own weight and imposed loading.


As buildings are of various shapes and sizes, the materials and floor framing approaches are brought together to form various unique combinations tailored to your requirement; so that the resulting floor systems do not deflect. The success of a construction site depends on two things—an effective pre construction planning program and the ability of the contractor to identify and adjust to unexpected conditions. They need to cater to the needs of a diverse group of customers, from self-builders to national home builders, we tailor our approach based on the client’s requirements of suspended floor construction.

Technical Field

The invention of suspended floor construction relates to a construction system and in particular to floor-forming form work and methods. It is however understood as the invention which is also applicable to walling form work and to walling systems and methods.The invention is not exclusive of application to flooring and to forming working methods but also involves systems for the construction of suspended concrete slab floors in housing or in multilevel buildings.

The challenge

It can be challenging for contractors to build suspended floor constructions that are acceptably flat and at level. Every elevated floor sags or deflects slightly beneath its weight, whether supported by steel beams or a cast-in-place concrete frame. And only if everything works right, the contractor’s finished surface is a perfect complement to structural deflection.


The method of constructing a suspended floor is described as a beam-forming form work process in which assemblies are organised in parallel alignment, the beam-forming form work assemblies are supported on a support base in stable equilibrium, consequently concrete is poured, and allowed to set, and the form work assemblies are removed from the set concrete for re-use in the process of suspended floor construction.

Evaluating Results

Post-placement, after the concrete hardens, data is collected and compared with pre-placement data to establish actual deflection. The results can be compared with the movement anticipated by the engineer. The floor consultant in addition to this evaluates the surface after each placement. Data is collected using a Dipstick. Profiles are generated and used to evaluate the flatness and levelness of the suspended floor. Levelness is gauged by measuring the percentage of all profiles that fall within a shallow horizontal envelope.
