CONCRETE CUTTING
Any damage during the hire period will be chargeable up to the full replacement or repairable cost.
Shepherd & Sons offers comprehensive concrete cutting and coring services backed by decades of industry expertise. We provide a diverse range of tailored solutions designed to meet the unique demands of your project. Our skilled operatives utilise cutting-edge equipment and advanced techniques to execute precision cuts.
Floor Sawing
Floor sawing is used to form a break line or joint within asphalt or concrete surfaces such as roads and airfield pavements. Shepherd & Son's utilise self-propelled diesel floor saws equipped with diamond blades.
Application Examples
🔧 Expansion joints
🔧Contraction joints
🔧 Removing damaged pavement sections
🔧 Drainage ducts
🔧 Break lines in slabs and roads for duct trenches
🔧 Creating clean cuts for joint sealant and crack repairs in asphalt and concrete surfaces
🔧 Full depth concrete bay replacements
Contraction Joints
🔧 Purpose:To control cracking that occurs as concrete shrinks during curing and cooling. They create a weakened plane so that if the concrete cracks, it does so in a controlled, straight line.
📐 Design: Usually sawn or formed into the slab shortly after placement (before shrinkage occurs). Shallow depth (about ¼ to ⅓ of the slab thickness).Typically, not filled with compressible material, but may be sealed to prevent water and debris ingress.
🛫 On Runways: Commonly spaced at regular intervals (e.g., 4.5m to 6m) depending on slab thickness. Often dowelled to allow load transfer across the joint.
Expansion Joints
🔧 Purpose: To allow for thermal expansion of the concrete slab without causing stress or buckling.These joints absorb movement caused by temperature changes or moisture-related expansion.
📐 Design: Typically include a compressible filler material (like foam, cork, rubber).Full-depth joint — goes through the entire thickness of the slab. May also include a sealant above the filler to keep out water and debris. Often occur at fixed points, like: Ends of a long slab where the pavement meets a structure (e.g., a building, drain, or fixed edge)
🛫 On Runways: Used more sparingly, often only where absolutely necessary. many expansion joints can weaken the pavement and increase maintenance needs.
