Sandersfire Firecrete mortars are dry blended, from high quality gypsum plasters, carefully graded natural and processed fire resisting aggregates,
and additives, to give excellent fire resistance, combined with ease of mixing, versatile workability range, high strength and exceptional acoustic

The controlled expansion develops a compressive membrane action, within rigid boundaries, resulting in excellent load bearing capability,
without the need for steel reinforcement, in other than exceptionally large openings.

Non-Shrinking, gas tight seals

Mixed with water, Firecrete is trowelled or poured into wall or floor penetrations around services to stop the passage of flame, smoke and toxic gases.

Excellent workability ranging from stiff to pourable consistency

Fully set within 2-3 hours.

Load bearing performance in floor seals

High compressive and flexural strength.
