Sika Injection-105 RC is a polyurethane injection foam, water-reactive, solvent-free, low viscosity, which, when cured, forms a tight, flexible foam with a fine cellular structure.

Features

• it swells up to 15 times in contact with water
• mixing ratio 1: 1 allows easy application with injection pumps in both one- and two-component
• the swelling reaction begins only after direct contact with water
• Sika Injection-105 RC can be injected like one-component products
• the rate of reaction (foam formation) depends on the temperature of the mixed material, the water properties and the hydrodynamic conditions
• at low temperatures (<+10 C) Sika Injection 105 RC can be accelerated with Sika Injection-AC10

Application

Sika Injection-105 RC is used for temporary static and working sealing of cracks, joints and voids in concrete, natural stone, brick, as well as in piling and foundation works. The product is particularly suitable for waterproofing structures where little movement is expected.
