Sprayed Concrete

Sprayed Concrete

Sprayed concrete is a concrete which is delivered to the point of installation in a sealed, pressure resistant hose or pipe, applied by “spraying” and this method of application also compacts it simultaneously.

Uses

Sprayed concrete is mainly used in the following applications:

·     Heading consolidation in tunnelling

·     Rock and slope consolidation

·     High performance linings

·     Repair and refurbishment works

Quality Sprayed Concrete Requirements

·     High economy due to rebound reduction

·     Increase in compressive strength

·     Thicker sprayed layers due to increased cohesion

·     Better waterproofing

·     High frost and freeze/thaw resistance

·     Good adhesion and tensile bond strength
