Description:

High build, high strength, very low shrinkage, patch repair mortar, compatible with concrete >45 MPa.

For the reinstatement of localised patch repairs and larger areas where suitable reinforcement is incorporated. Renderoc HB70 is alkaline in nature and will protect embedded steel reinforcement. It is specifically designed for locations where high build and high compressive strengths are required or in locations where good abrasion resistance is necessary. The mortar is suitable where resistance is required to chlorides and carbon dioxide.

Uses:

Renderoc HB70 is designed for vertical or horizontal use. It can be applied up to 40 mm thickness in vertical sections. Greater thickness can be achieved in small pockets or by the use of formwork. In horizontal locations, Renderoc HB70 can be applied up to 150 mm thickness. Thicker sections can be built up in layers. The material should not be applied at less than 5 mm thickness. Thicknesses greater than those nominated in large areas can be achieved by spray application. Consult your local Parchem sales office for further information.

Features & Benefits:

• High strength and high abrasion resistanceHigh build repairs
• Extremely low permeability provides maximum protection against carbon dioxide and chlorides
• Excellent bond to the concrete substrate
• Shrinkage compensated
• Pre-bagged to overcome site-batched variations – only the site-addition of clean water required
• Can be applied by the wet or dry spray process for fast, exceptionally high build repairs with enhanced characteristics
• Contains no chloride admixtures
• Suitable for internal and external use
