Coltman 50th Year Logo



Coltman prestressed concrete hollowcore floor and roof slabs comprise hollow and solid concrete flooring units, nominally 1200mm wide and of various depths placed side by side with a grouted joint.

Precast concrete floors provide our customers with a quick form of flooring construction, enabling the principal contractor to progress in most cases to the next level of construction within a day of the precast concrete hollowcore flooring units being installed, saving time and money.

Layout drawings are prepared for use during site erection by Coltman Precast Concrete floors fixing crew or by others employed by the principal contractor.
