Precast Hollowcore Flooring

Precast Hollowcore Flooring is a reinforced concrete Hollowcore flooring system combining ease of construction with the security of pre-cast concrete.
Precast Hollowcore Flooring adds Strength and dependable to your home. Croom Concretes floors are designed and installed to individual requirements using the latest technology and manufacturing techniques.

How Does Precast Hollowcore Flooring Work

Slabs are manufactured to differing lengths to accommodate each housing type. These pre-cast slabs are supported by the internal cavity wall and span across the upper floor. Spaces between the slabs are grouted on-site producing a solid structural floor that resists differential movement.
Electrical and plumbing services as well as insulation and underfloor heating sit on top of this solid structure, tucked away underneath a screed or timber floor.

A Home for Life

Hollowcore Concrete floors create a strong, studier home, which is less prone to movement. An investment now will reap lifelong benefits for the family including noise reduction, increased fire protection and elimination of the risk of damp or rot in later years.
If considering a Hollowcore concrete floor, discuss this with your architect at the initial stages of the design process so the system can be incorporated at the onset.
On receipt of a copy of your plans the technical team at Croom Concrete team will provide a technical floor design and quotation free of charge.

If you wish to proceed the team will visit your site to take final measurements two weeks prior to delivery, leaving a fully finished structural floor ready for your builder to continue work the next day.
