Conbextra HS High-Strength Precision Grout – Perth WA
Conbextra HS High-Strength Precision Grout – Perth WA
Conbextra HS is a high-flow, dual shrinkage-compensated cementitious grout for precision applications requiring rapid strength gain and high ultimate compressive strength. Fosroc publishes compressive strengths of approximately 26 MPa at 8 hours and 95 MPa at 28 days when mixed at flowable consistency, subject to test conditions and the current technical documentation.
The grout is commonly selected beneath machine bases and structural components where reliable load transfer and a quick return to service are important. Its high initial flow, useful flow retention and ability to suit both large and small pours can assist placement around baseplates and congested details. A hydrogen-free, chloride-free expansion system compensates for shrinkage in the plastic and hardened states.
Precision grouting requires careful preparation. The substrate and underside of the baseplate should be clean, sound and free of contamination. Formwork must be strong and watertight, with enough head pressure and access to permit continuous placement. Mixing water, grout depth, working time, temperature limits, curing and loading time must be checked against the latest Fosroc Technical Data Sheet. Published laboratory strengths should not be treated as a substitute for project engineering requirements.

FAQ’s
Question: When should Conbextra HS be selected?
Answer: Conbextra HS suits precision grouting where high flow, rapid strength development and high ultimate strength are required, including grouting beneath machine bases and structural components.
Question: What compressive strength does Conbextra HS achieve?
Answer: Fosroc publishes approximately 26 MPa at 8 hours and 95 MPa at 28 days at flowable consistency. Results depend on mixing, curing, temperature and test conditions.
Question: Is Conbextra HS shrinkage compensated?
Answer: Yes. Fosroc describes Conbextra HS as dual shrinkage compensated, using an expansion system that acts in both the plastic and hardened states.
Question: Is Conbextra HS available in Western Australia?
Answer: Safari Group supplies Conbextra HS from Canning Vale, Perth. Contact our team to confirm availability and suitability for your machinery, civil or industrial application.
