Economical and Practical - Renovation of Parking Lot in a Large Commercial Center in Nanjing

Project Name: Parking Lot of a Large Commercial Center in Nanjing

Renovation time: September 2007

Comparison of renovation plans: The floor is a C30 concrete floor constructed in 2000, with an area of 13000 square meters. Due to long-term vehicle rolling and wear, the garage has experienced dust and sand formation. The construction party had planned to use ground polishing and then apply epoxy flooring. After calculation, the renovation cost is: 55 yuan/square meter * 13000 square meters=715000 yuan, and the epoxy flooring has a lifespan of 5 years, The cost of using it for 30 years is 715000 yuan * 6 times=4.29 million yuan. We suggest that the construction party adopt a concrete sealing and curing agent treatment plan, and the renovation cost for 30 years is: 65 yuan/square meter * 13000 square meters=845000 yuan. Compared with the plan of using epoxy to renovate the floor, it saves 3.445 million yuan, truly achieving a super value product that can be used for 30 years in one construction. It also solves the problem of water seepage in the concrete pores during the rainy season that has long plagued the construction party

Clean and polish the original ground, then spray concrete sealing and curing agent

Advantages: 1. It can be used for more than 20 years without dust or sand formation

2. Dust proof, wear-resistant, load-bearing, easy to clean, and the longer used, the brighter the surface gloss

3. Convenient construction and short cycle, without affecting the normal production of the factory
