Lightweight, strong, and versatile.
The Timberless-33 prefabricated flooring system is ideal for taller structures with its ability to maintain a lighter foundation while reducing the supporting elements of the foundations and/or podiums. As a result, lower weight delivers less foundation impact and ultimately less cost. Additionally, the Timberless-33 system is ideal for areas of extreme winter weather conditions, as it can be dried in quickly with one trade driving the critical path.
Timberless-33 is ideal for Mid-Rise projects like:
Commercial
Retail
Mixed-Use
Hospitality
Student Housing
