Access Corridor

Description

This project involved the refurbishment of an access corridor subjected to heavy foot and pump truck traffic, serving as a passageway for restaurants and stores. The existing screed was failing, with cracks appearing in various areas. The objective was to provide a durable, slip-resistant flooring solution capable of withstanding the corridor’s high traffic demands.

Project Scope

• Mechanically ground the floor to clean and texture the substrate, ensuring optimal adhesion for the new flooring system.
• Installed 20mm x 20mm saw cuts around all checker plates and stanchions to create anchor points for the hand-laid material
• Repaired and replaced joints using a rubber-reinforced polyurethane joint and arris repair mortar to enhance structural integrity.​
• Applied a damp proof membrane (DPM) incorporated with aggregate to provide a mechanical key for the subsequent flooring system.​
• Hand-laid a 6mm polyurethane screed using a steel float trowel, offering chemical resistance, slip resistance, and durability.
• Saw cut a 10mm x 6mm expansion joint around the perimeter of all checker plates and installed additional jointing compound to provide flexibility and prevent cracking.​

Project Overview

The project began with the mechanical grinding of the existing floor to remove contaminants and prepare the substrate. Saw cuts were made around checker plates and stanchions to create anchor points for the new material. Door thresholds received additional chase cuts, and the areas were ground to ensure the new flooring would sit flush with existing concrete, eliminating trip hazards. Joints were repaired using a rubber-reinforced polyurethane mortar, followed by the application of a damp proof membrane with an aggregate scatter to enhance adhesion. A 6mm polyurethane screed was then hand-laid, providing a durable, slip-resistant surface. Finally, expansion joints were installed around checker plates to accommodate movement and prevent future cracking. The project was completed on time, ensuring minimal disruption to the corridor’s use as a vital access route for restaurants and stores.
