Freecall Ultrafloor on 1800 858 723



Ultrafloor bearers provide an extremely efficient method for constructing suspended low lying slabs (i.e. ground floor) and detention tank lids. The bearers are used in conjunction with a traditional Ultrafloor slab to create a concrete bearer and joist flooring system.

As no propping, or formwork, is required the Ultrafloor system is the cheapest, fastest and most durable solution for constructing a suspended slab when underside access is limited, or impossible. 

Bearer Range  

Any Ultrafloor beam can be used in a bearer and joist arrangement. 170 Lintels and R beams are typically supported on single brick piers and run along the inside of external walls. M and C beams are commonly used as internal bearers on standard 230mm wide brick piers.

Ultrafloor bearers are generally designed with no mechanical connection to the slab joists. However in special circumstances, when increased bearer capacity is required, they can be engineered as composite beams through the use of steel dowels connecting the bearer into the in-situ slab topping.
