Fosroc Renderoc Hb40 Plus 20kg

Renderoc HB40 Plus is a medium-weight, high-build concrete repair mortar designed for vertical and overhead structural repairs. Supplied as a pre-blended, single-component powder, it requires only the addition of clean water on site to produce a consistent, polymer-modified mortar with excellent workability and long-term durability. Formulated with advanced cementitious binders, fillers, and chemical additives, it offers rapid strength gain, low permeability, and high resistivity for enhanced performance in aggressive environments.

Key Features:

• Compatible with concrete strengths from 25 to 50 MPa

• Achieves 50 MPa compressive strength at 28 days

• Shrinkage compensated – ensures dimensional stability and reduces cracking

• High resistivity – supports durability in corrosive environments

• Low permeability – resists water, CO₂, and chloride ion ingress

• High-build formulation – ideal for vertical and overhead applications

• Wet-spray compatible – enables fast, efficient application

• Abrasion resistant – suitable for industrial and high-wear areas

• Sustainable – incorporates supplementary cementitious materials for a reduced carbon footprint

• Pre-bagged – ensures batch consistency and eliminates site mixing variability

• Complies with EN 1504-3 Class R3

Typical Uses:

• Structural repair of concrete in vertical or overhead sections

• Repairs where reduced permeability and high resistivity are required

• Infrastructure maintenance in aggressive or corrosive conditions

• Not suitable for use with galvanic anodes – consider Renderoc HB40 instead
