About

Void formers, also known as foam plugs, are materials used in the construction industry to create voids or empty spaces in concrete structures. They are typically made of expanded polystyrene (EPS) foam and are used in precast concrete panels, ribbed slabs, and hollow-core slabs to reduce the weight of the concrete while maintaining its structural integrity. Void formers can also be used to create insulation and to improve the thermal performance of a building. These void formers are used in a variety of applications such as precast concrete, in-situ concrete, and flooring systems. We also offer other products such as insulation, formwork, and drainage solutions. Our products are used in a variety of projects including residential, commercial, industrial, and infrastructure projects.
