Prestressed Precast Concrete Hollowcore Floors (also known as Slabs or Planks)

Hollowcore Flooring are prestressed precast concrete slabs featuring continuous cylindrical voids which run internally down the length of each precast slab. The number of voids varies depending on size and strength, with a key advantage of reducing the overall weight when compared to other floor slabs of equal thickness and strength.

 

The lightweight nature of this precast floor system offers additional benefits due to significant saving in transportation, material and labour costs. It also enables longer spans with a decreased depth ratio to be manufactured without compromising on strength and durability. Hollowcore Flooring can also be known as slabs or planks.

 

Hollowcore flooring is suitable for a range of applications including commercial buildings, car parks, offices, apartments and in all types of housing. Each precast floor slab is placed side by side and sealed with a grouted joint to provide a durable flooring solution which has a fast installation and can support even heavy loads. Designed to easily fit into any structural system, whether it is steel, in-situ, precast or concrete masonry, at ACP (Concrete) Ltd our precast concrete planks are typically 1200mm wide and are available in standard depths from 150mm to 500m. The spans of Hollowcore floor can be up to 20.5m.

 

Prestressed precast concrete floors provide our customers with a quick and cost-effective form of flooring construction which enables the Principal Contractor to progress in most cases to the next level of construction within a day of the Hollowcore Flooring being installed, saving you time and money.

 

All our prestressed precast concrete planks are all CE marked and designed and manufactured to Eurocode 2 industry standards.

    Wide range of sizes to suit various spans and loads

    At ACP (Concrete) Ltd, our prestressed precast concrete floor slabs are manufactured in a range of longer sizes to suit various spans and loads, providing flexible and tailored solutions to suit each application.

     

    One advantage with this flooring solution is due to the lower weight created by the symmetrical voids. This enables longer spans to be manufactured, which is particularly beneficial if supporting columns are unfeasible, undesirable or in applications such as multi-storey car parks. It can also provide valuable additional space by reducing the number of beams and columns required for support. The voids are sometimes used as service ducts for plumbing, electrical cable or data transmission systems.

  • Installation and Delivery Guidance

    Brief Overview: How to install Prestressed Precast Hollowcore Flooring

    Hollowcore Flooring can be installed directly from the delivery vehicle using a crane to its final position due to each unit being referenced individually to suit the approved ACP (Concrete) Limited design drawing.

     

    The units are lifted in using the choke hitch method with one unit in each individual bay of the drawing having lifting pins cast into them to place it into its final position.

     

    Once all the units have been installed the C35 concrete grout is placed in the joints to tie the floor together.
