What is BuildBlock?
excellent products, excellent people, excellent results
The BuildBlock Building Systems consists of interlocking, lightweight, expanded polystyrene forms. Designed to be an integral part of the wall, the forms remain in position after the concrete is placed. The insulating capacity of expanded polystyrene coupled with the structural integrity of reinforced concrete is a powerful combination – it makes BuildBlock walls stronger, safer, quieter and more energy efficient. In test after test, BuildBlock walls meet or exceed standards set by building codes. Add our talented and service-oriented technical support network to our excellent products and it’s clear: BuildBlock is the Total Building Solution for your building projects.
