Sha Tin, New Territories
Pok Hong Estate is the public rental estate developed by Hong Kong Housing Authority (HKHA) in year 1978.
Situated inside the Pok Hong Estate, Pok Hong Shopping Centre was opened in 1982 with a lettable area about 3,300 square metres.
The reinforced concrete structure was seriously deteriorated after long period exposure in the aggressive environment. The HKHA launched a large-scale improving project to revitalise the shopping centre.
The repair works included patch repair with high-build concrete repair mortar and recasting with non-shrink cement grout. To improve the durability and further enhance the protection on the repaired concrete columns, columns were wrapped with Carbon Fibre Reinforced Polymer (CFRP).
