PP Hollow Construction Formwork Advantages
1. PP Formwork The construction came out great, and the exposed concrete looks amazing
-
The surface is dense and smooth, doesn't absorb water or seep slurry. The poured concrete wall is flat and shiny, with no honeycombing, rough spots, water marks, or color differences, meeting the standard for fair-faced concrete.
2. Easy to demold, saves time and effort during construction
-
Made of polypropylene, it doesn’t stick to cement, and in most situations you don’t need to apply a release agent; just tap lightly to remove the mold, and it won’t pull off the concrete surface, keeping the edges of the component intact.
3. Higher turnover means lower overall costs
-
Product turnover far exceeds that of plywood and bamboo plywood; waterproof and moisture-proof, won’t mold or delaminate, won’t easily warp or get damaged in basements, coastal damp areas, or saline-alkali sites, and has low wastage.
4. Lightweight and easy to work with, making construction convenient and safe
-
Lightweight, can be handled by one person, reducing hoisting and labor; can be sawed, nailed, or drilled on site, fitting beams, columns, arches, and custom-shaped components.
5. Environmentally friendly and widely applicable
-
Using plastic instead of wood reduces logging, is recyclable, and doesn't create construction waste pollution; suitable for residential shear walls, basements, bridge piers, water channels, precast concrete components, factories, and various other civil engineering projects.
