KHIA ID: 8947
Industry: Other (OTHER)
Application: FPA-Floor Problem Areas (FPA)
Substrate: Concrete
Customer Location: Piedmont, NC, USA
Application Date: February 2023
Products: Belzona 2211 (MP Hi-Build Elastomer), Belzona 2911 (Elastomer QD Conditioner), Belzona 4111 (Magma-Quartz), Belzona 4411 (Granogrip), Belzona 4911 (Magma TX Conditioner)
Problem: The metal plate covering the expansion joint outside an operating room in a sterile area was trip hazard because the plate was lifting up and separating from the floor. Several employees had tripped and surgical carts toppled from the plate.

Removal of plate reveals extensive amount of debris in a sterile area at doorway to operating room.

After the plate was removed, the joint was cleaned out and Belzona 4111 was applied to build out the joint nosings.

Once Belzona 4111 cured, a thick coating of Belzona 4411 was applied. It was chosen for its fast cure and durability.

Last step was to condition the joint area with Belzona 2911 and tape off / fill with Belzona 2211 Elastomer.

Application Situation
We conduct this work on the weekends when the hospitals are slower. Typically we arrive on a Friday to do most of the work and come back Saturday morning after the Belzona 4411 has time to cure. These joints are considered quite costly however, the main benefit is smooth joints, no trip hazards and also sanitary joints with no debri and bacteria.
Application Method
Manual tools were used to remove the plate and the grinder for joint nosing preparation work. The Belzona 4111 application was done with trowel after the area was taped off. Belzona 4411 was applied with a stiff bristle brush after the Belzona 4111 had cured sufficiently. Next morning the joint space was grinded a little to allow for adhesion of the Belzona 2211 which was applied using a Belzona applicator. The area was returned to service in under 24 hours.
Belzona Facts
These are not the cheapest expansion joints on the market; actually very expensive but they are long lasting, safe, sanitary, and joint of choice in many application types .
