Access Corridor
Method/Preparation
The screed laid was failing and cracks were starting to appear in various areas. As a quick fix the client had installed checker plates in an attempt to protect the joints from cracking further. A decision was made by the client to leave the checker plates in, so our team started to mechanically grind the floor to clean and texture the substrate. We then installed 20mm x 20mm saw cuts around all checker plates and stantions, the hand laid material will fill these holes and cure, gripping the floor like an anchor point.
Our team are on site
hand laying the system to
attain an excellent finish.
This is a photo of one leg
of the corridor, it
branches off into 2 other
sections, totaling just
under 400m2 in size.
Application/Installation
Our team installed extra 10mm x 6mm chase cuts at the door thresholds, then used a hand grinder to grind the area in front of where we installed the chase cut, to ensure the material sits flush with the existing concrete, eliminating and trip hazard. Next, we repaired and replaced the joints using a rubber re-enforced polyurethane
joint and arris repair mortar, and then installed a DPM incorporated with aggregate
to provide a mechanical key for the following system.
This photo shows some of
the cracks that had
appeared and why the
client called us in.
Below is an image of the
checker plate and floor
before our team started on
site.
Application/Installation
Once the DPM had been installed and an aggregate scatter laid, our team moved on to installing 6mm polyurethane screed, hand laid by the use of a steel float trowel as shown below. This system was ideal for the client with its chemical resistance, slip resistance and durability ticking all the necessary boxes. Once laid we then saw cut a 10mm x 6mm expansion joint around the perimeter of all checker plates and installed more jointing compound, introducing an extra joint would give more flexibility and security againt cracking around the checker plates.
The improvement is
already here to see before
our team finishes off the
details around the checker
plates.
This is a great money shot
of our team on site hand
laying the 6mm
polyurethane screed.
Result
This corridor is subject to heavy foot and pump truck traffic, acting as an access route for restaurants and stores, meaning that the project had to be completed on time, with good planning and communication by Optimum ensuring the process went as smooth as possible!
The finished floor and
joints look really good,
ready to provide
a better
working enviroment for
the client.
