Saw Cut & Seal

Every concrete floor will crack as it cures and dries as water leaves the concrete and the volume shrinks. With good design and accurate saw cuts, we can define where the cracks will land, and hide them under a neat sealed cut as opposed to letting them occur at random.

Improves concrete appearance by controlling cracks

Sawcuts are a feature of most ground floor slabs and are straight line cuts made by a diamond tipped blade to a depth of over 25% of the slab depth. These cuts are made by blades of between 5 and 10mm diameter. This joint is then sealed with the application of a thick liquid resin such as mastic.

The saw cuts are installed on a predetermined grid as per the design and encourage cracks in the concrete to fall under the sealant, thus making them invisible from above.

Our process

Saw Cut and Seal application

Firstly, the position of the sawcut is marked in conjunction with the drawings under supervision of an engineer.

Cut locations are marked
Saw cutters use a powered cutting machine to cut straight lines at prescribed depths
Dust is vacuumed and suppressed during cutting
Joints are sealed with a gun that squeezes resin into the joint before it is ‘struck off’ by a skilled tradesman.

Typically sawcuts are performed 8 – 48 hours after finishing operations, sealing takes place normally 28 days later.
