Precast Concrete is a durable and long lasting building product. If properly maintained it will stand the test of time.
The beauty of precast concrete with its variety of colours and textures, together with its versatility and function, is an integral component of the building envelope. By following a simple program of inspection and maintenance precast concrete can guarantee the designed service life of a building.
To ensure the continued performance of the wall system and to maintain the warranty, visual inspections should be carried out at regular intervals. It is recommended that these inspections be carried out annually.
Attention should be paid to the caulked joints, surface appearance and connections. Any signs of deterioration should be documented at once with a copy of the written report sent to the manufacturer. Any applicable defects reported within the warranty period shall be remedied by the manufacturer.
The owner is urged to maintain this annual inspection program past the warranty period in order to optimize the life of the structure.
