Conbextra HF is a dual shrinkage-compensated, high-flow cementitious precision grout for applications requiring excellent flow and long flow retention. Fosroc lists it for grout gaps up to 125 mm, making it suitable where grout must travel beneath equipment or through restricted-access areas while maintaining consistent placement.

Typical applications include critical machine baseplates, sole plates, columns, precast panel joints and pumped grout installations where pouring access is limited. The grout can be pumped or poured, develops strength rapidly, provides high ultimate strength and low permeability, and uses a hydrogen-free gaseous expansion system to compensate for shrinkage. The formulation is chloride free.

High-flow performance does not replace correct site preparation. Concrete and steel contact surfaces should be sound, clean and free from contamination. Formwork must be rigid, watertight and arranged to maintain suitable grout head and continuous flow. Plan venting and placement to minimise trapped air. Water addition, mixing, minimum and maximum depth, working time, temperature, aggregate addition where permitted, curing and loading should follow the latest Fosroc Technical Data Sheet and project specification.

FAQ’s

Question: What is high-flow grout used for?
Answer: High-flow grout is useful where material must travel beneath baseplates, around detailed components or through restricted-access areas while retaining enough flow for complete placement.

Question: What gap size suits Conbextra HF?
Answer: Fosroc currently lists Conbextra HF for grout gaps up to 125 mm. Confirm the minimum depth and all project-specific limitations in the latest Technical Data Sheet.

Question: Can Conbextra HF be pumped?
Answer: Yes. Fosroc describes Conbextra HF as suitable for pumped or poured installation, provided the equipment, mixing and placement method comply with current technical guidance.

Question: Where can I buy Conbextra HF in Perth?
Answer: Safari Group supplies Conbextra HF from Canning Vale. Contact our team to confirm stock and suitability for your machinery, precast, civil or industrial grouting project in WA.
