Top 10 Companies in the Calcium Sulfate Anhydrite Dihydrate Hemihydrate Floor Screed Market (2026): Market Leaders Powering Global Construction

MARKET INSIGHTS

Global calcium sulfate anhydrite dihydrate hemihydrate floor screed market size was valued at USD 1.87 billion in 2025. The market is projected to grow from USD 1.98 billion in 2026 to USD 3.14 billion by 2034, exhibiting a CAGR of 5.9% during the forecast period.

Calcium sulfate floor screed encompasses three primary forms – anhydrite (fully dehydrated calcium sulfate), dihydrate (gypsum-based), and hemihydrate (semi‑hydrated, also known as alpha or beta hemihydrate) – each offering distinct performance characteristics for underlayment and leveling applications in residential, commercial, and industrial flooring systems. These self‑leveling or pump‑applied screeds are widely valued for their low shrinkage, superior flatness tolerance, and compatibility with underfloor heating systems, making them a preferred alternative to traditional cement‑based screeds across modern construction projects.

The market is witnessing steady growth driven by rising construction activity across Europe and Asia‑Pacific, increasing adoption of energy‑efficient underfloor heating systems, and a growing preference for faster‑curing, high‑performance flooring solutions. Stringent building regulations promoting sustainable and low‑carbon construction materials are encouraging contractors and developers to shift toward calcium sulfate‑based screeds. Key industry participants including Saint‑Gobain Weber, Knauf, and Lafarge (Holcim Group) continue to expand their product portfolios to address evolving construction demands globally.
