BIG MISTAKES WHILE USING SHUTTERING PLYWOOD IN CONSTRUCTION ?
Shuttering plywood (also known as Film Faced Shuttering plywood) in construction is crucial for creating concrete forms. However, there are eight common mistakes that can lead to issues with the final construction:
Incorrect Plywood: Using commercial plywood of inappropriate grade can result in poor formwork quality. Need to always use 100% High Densified, BWP grade film faced shuttering plywood.
Inadequate Support: Failing to provide proper bracing and support can lead to formwork failure or deformation. The support system should be designed to handle the load of wet concrete and the construction environment.
Poor Sealing and Finishing: Not sealing the plywood properly before pouring concrete can lead to the plywood absorbing moisture, which can affect the quality of the concrete surface. Additionally, rough or uneven surfaces on the plywood can leave marks on the concrete.
Improper Joint Alignment: Misaligned joints between plywood sheets can create gaps or irregularities in the concrete formwork, leading to defects in the final concrete structure.
Neglecting Maintenance: Not maintaining the plywood properly between uses can lead to deterioration and reduced effectiveness. Plywood should be cleaned, repaired, and properly stored to extend its lifespan.
Overloading: Overloading the formwork with excessive weight can cause deformation or failure. Proper calculation of the load-bearing capacity is essential.
Ignoring Local Conditions: Not considering environmental conditions such as humidity and temperature can affect the performance of plywood and the curing of the concrete.Inadequate Fastening: Using insufficient or incorrect fasteners can lead to formwork instability. Ensure that all connections are secure and appropriate for the load they will bear.
Avoiding these mistakes involves careful planning, proper material selection, and regular inspections during the construction process.
