Perhaps, the constant dampness of the washing bay has resulted in the above situation over the long run. In the part of the washing bay further away from the water dispensing unit, crack lines have formed on the ground, as though a mild earthquake has taken place. The toilets in most households are laid with ceramic tiles. Toilet is a place which is constant damp as well, and the tiles in my house’s toilet are not showing any signs of weakness after a good 20 years. Perhaps, HDB could consider laying the washing bay with ceramic tiles when designing future HDB multi-storey carparks.
For existing washing bays, perhaps the respective town councils could conduct regular inspections to ensure that they are in good condition, and perform the necessary maintenance work as and when required.
