Founded in 2021, EnviroCrete was established with a clear mission: to deliver high-quality lightweight insulating concrete roof deck solutions that meet the demanding structural, thermal, and code-compliance requirements of construction in Florida.
Our leadership and technical team are actively involved in the lightweight insulating concrete industry and collaborate with organizations dedicated to advancing LWIC standards, performance, and best practices across the state. This commitment ensures that every EnviroCrete installation aligns with evolving building codes, engineering requirements, and long-term roofing system performance.
Lightweight concrete
WHAT IS LIGHTWEIGHT INSULATING CONCRETE (LWC)
Lightweight Insulating Concrete (LWIC) is a cement-based material produced by combining Portland cement, water, air, and—depending on the system—lightweight aggregates or preformed foam to create a hardened structure with insulating properties. When oven-dried, LWIC has a unit weight not greater than 50 pounds per cubic foot, significantly lighter than structural or conventional concrete.
This reduced density allows LWIC roof deck systems to provide structural support, thermal insulation, slope-to-drain capability, and long-term dimensional stability within a single monolithic layer. Compared to traditional concrete systems, LWIC delivers substantial weight savings while maintaining compressive strength and compatibility with modern roofing assemblies.
Beyond weight reduction, LWIC roof systems are:
- Non-combustible and compatible with fire-rated assemblies
- Resistant to wind uplift and moisture intrusion
- Dimensionally stable without shrinkage gaps
- Energy-efficient and permanently bonded to the roof deck
Approved for use in Florida’s high-wind and hurricane-prone environments under the Florida Building Code.
These characteristics make LWIC one of the most reliable and performance-driven roof deck insulation systems for commercial and institutional construction across Florida.
