Mapei HB25

Planitop HB25 is a polymer-modified cementitious repair mortar designed for repairing vertical or overhead concrete surfaces. This mortar has medium mechanical performance characteristics and can be applied to substantial thickness without the need for formwork.

Key Features

• Excellent Adhesion: Superior adhesion to existing concrete surfaces provided they are saturated with water and reinforcing bars are treated with Mapefer before application.
• Good Mechanical Performance: Designed flexural and compressive strength, with modulus of elasticity, thermal expansion coefficient, and permeability coefficient similar to that of medium quality concrete.
• Easy Application: Forms an easy-to-apply thixotropic mortar that can be applied without sagging, even on vertical and overhead surfaces, in substantial thickness.
• Eco-Friendly Formula: Free from chlorides, making it environmentally friendly.

Typical Usage

• Concrete Surface Repair: Repair deteriorated concrete surfaces and soffits of beams damaged by rusted reinforcing bars.
• Fast Repairs: Quick repairs to vertical, horizontal, overhead concrete, or mortar surfaces.
• Large Area Reinforcement Cover Reconstruction: Reconstruction of concrete coverings of reinforcing bars over large areas.
• Surface Irregularity Repair: Repair surface irregularities including exposed aggregate, joints between new and old concrete, holes in formwork concrete, protruding steel, etc.
