Keeping concrete strong August 1st 2008 After an initial survey of the
warehouse floor, CG
Flooring Systems (CGFS)
recommended slab and joint
repairs, with a 10mm fast
track cementitious pump
screed installation for multimetal
and steel stockholder,
Aalco's Halesowen plant.
During initial slab repairs it
was found that the concrete
slab was not thick or strong
enough to meet future
operating requirements.
Typical thickness is 150mm,
and the floor was only
75mm in the areas that
required repair. This was not
suitable for sustaining heavy
MHE traffic. CGFS submitted
a proposal to affect a
proper repair. Due to
the time frame and
the need for the
warehouse to
remain operational,
CGFS worked on the
solution over two weekends.
The first weekend involved
breaking out the floor area to
180mm deep. The areas
were saw cut for sharp arris
edges, where dowel bars
were inserted to the arris
edges as a load transfer
mechanism. Damp Proof
Membrane (DPM) and
reinforcement mesh were
installed prior to pouring a
rapid strength concrete floor.
The process offered an
additional intensity to the
floor capacity.
The final weekend
included surface preparation
by shot blasting and
diamond grinding. A 10mm
cementitious fast floor
system was then installed to
1135m2 in one day. The floor
dried within 3 to 4 hours. More articles from C G Flooring Systems Ltd: |
