Renderoc HS Xtra

Description

Description:
Renderoc HS Xtra is a high specification cementitious repair mortar that is reinforced with special fibers for enhanced physical properties. It is supplied as a ready to use blend of dry powders, which requires only the addition of clean water to produce a highly consistent repair mortar suitable for structural concrete and masonry repairs. Renderoc HS Xtra may be hand applied or sprayed with suitable equipment, please see application method statement for details.

Uses:
Renderoc HS Xtra is suitable for hand and spray application for repairs where high load bearing is required. Typical
applications would include, but not be limited to, the following:

• Vertical and overhead repairs to restore ‘cover Crete’.
•  General concrete and masonry repairs.
• Voids greater than 10 mm deep.
• Repairs to honeycombing.
• Larger scale repairs where formwork cannot be erected.

Advantages:
Renderoc HS Xtra features Dimensional Stability Technology – a new materials technology which controls the rate of drying shrinkage such that, when used correctly:
i. The dimensions of the repair remain stable; and thus
ii. Eliminating failure, due to shrinkage cracking.
This in turn leads to a series of associated benefits:

• Cost effective – shrinkage control enables repairs to be completed ‘right first time’.
• Enhanced durability – works in tandem with extremely low permeability to prolong effective working life.
• Compatibility – aligns performance closer than ever before to that of host concrete.
• User friendly – specifically developed to provide uneasy-to-apply product, suitable for local conditions.
• Definable performance – positive benefits are easily demonstrated via a single, simple measurement.
