Commercial car parks must be durable, safe and intelligently designed to satisfy demanding parking requirements. They are exposed to frequent vehicular traffic making them susceptible to cracks and moisture.

Modern car parks must meet building codes and safety regulations including waterproofing. The right concrete waterproofing application ensures lasting durability to car park users.

Waterproofing Roof Car Park (Top Deck)

Signs of damage include deterioration of the stucco, railing, fixtures or water intrusion that affects the structural elements below. If you noticed any of these signs, get Sydney waterproofing experts to inspect, repair and waterproof the concrete deck.

Waterproofing Multi-storey Car Park (Intermediate Deck)

Water penetrating the floor causes efflorescence, a visible white mineral stain on the concrete. In time, this can cause severe damage not only to the structure but also to people’s health.

The solution to fix efflorescence is to stop moisture penetration. This can be done with waterproofing and improving of expansion joints. Expansion joints allow possible movement from heavy traffic while stopping water leaks. This process may involve a qualified waterproofing contractor in Sydney.
