Renderoc HS Xtra
High Strength Rapid Setting Structural Repair Mortar for Urgent Reinstatement
Authorized Project Distributor — Fosroc India | Space Arc Engineering, Ghaziabad
Product Overview
Renderoc HS Xtra is a factory pre-blended, single-component, rapid setting, high strength polymer-modified cementitious structural repair mortar for applications where structural reinstatement must be achieved quickly and the element must return to service within hours rather than days. The rapid setting formulation achieves high early compressive strength at 3 to 4 hours after application — allowing loads to be applied, traffic to run over, or formwork to be struck much earlier than standard setting repair mortars. This makes Renderoc HS Xtra the preferred choice for bridge deck repairs that must be completed and opened to traffic within a single overnight road closure window, airport runway and taxiway repair with minimum downtime, industrial floor repair where production cannot be stopped for days, and emergency structural repair of any element that must be returned to service urgently. Despite the rapid setting chemistry, Renderoc HS Xtra achieves high ultimate compressive strength (over 55 MPa at 28 days) and is compatible with Nitobond EP bonding primer for maximum adhesion to prepared substrates. Space Arc Engineering distributes Renderoc HS Xtra for urgent structural repair and bridge maintenance projects across Delhi NCR, Ghaziabad, and Northern India.

Frequently Asked Questions
How early can loads be applied after Renderoc HS Xtra repair?
Renderoc HS Xtra is specifically designed for early load application. In most applications at 25 degrees C, pedestrian loads can be applied at 2 to 3 hours and vehicular loads at 4 to 6 hours after application, once the specified minimum early strength has been achieved. For bridge deck repairs, verify that the repair has reached the minimum strength for opening to traffic using rebound hammer testing or temperature-matched curing cube testing if the engineer requires written confirmation before opening. In cooler weather, strength development slows and opening times should be extended.
Does the rapid setting chemistry reduce ultimate strength in Renderoc HS Xtra?
No. Renderoc HS Xtra achieves both rapid early strength and high ultimate strength of over 55 MPa at 28 days. The rapid setting system does not compromise final performance. The polymer modification of the mortar also ensures good adhesion and durability, making Renderoc HS Xtra a fully structural repair mortar despite its rapid setting characteristics — not simply an emergency short-term fix.
Can Renderoc HS Xtra be applied in hot weather conditions common in India?
Rapid setting mortars are more sensitive to temperature than normal setting products. In hot conditions (above 35 degrees C substrate and ambient temperature), the working time of Renderoc HS Xtra reduces significantly, which can make it difficult to mix, apply, and finish before the mortar stiffens. In very hot weather, pre-wet the substrate with cold water, use cold mixing water, shade the work area, and mix only the quantity that can be placed within the working time. In extreme heat (above 40 degrees C), night working should be considered for better control of the setting time.
