Floor Joint Resealing

Floor joints act as a controlled crack in concrete slabs and are positioned to allow the floor to move. Shrinkage from drying and thermal changes over time are the main causes of floor joint movement. 

 

Diamond Grind uses sealants that are rigid enough to provide support and protection the facing edges yet flexible enough to accommodate opening of the joint and remain bonded to at least one face. 

 

Due to movement, joints are often the primary source of maintenance and repair for industrial and warehouse floors with the facing edges of joints constantly vulnerable to damage from hard wheeled mobile plant and equipment.

 

Joints with crumbling edges are commonplace on most industrial and warehouse floors and should be seen as an early indication of more serious long term damage.

Joint crumbling only gets worse with age”

By resealing joints, Diamond Grind can reduce and even prevent further edge crumbling thereby eliminating the need for expensive remedial work in the future.

 

Joint resealing is a relatively simple repair however the process works best when the edge damage is detected early. If more serious damage has already occurred, the need to re-construct the joint may be required. (see opposite).

The Problem

Mobile plant traffic impact remaining 'soft' edges and sealant causing further crumbling of facing edges.

The Solution

Damaged joint is reduced by introducing a semi- rigid joint sealant. Mobile plant now transition from surface to surface smoothly. 

Floor Joint Repair

Early detection and repair of damaged floor joints has a significant impact on the overall maintenance cost of a commercial floor. 

 

Inspection of the joint sealant should be done regularly to ensure is still performing adequately by protecting the joint edge. 

 

Once the damage has progressed past the scope of re-sealing the joint, it becomes necessary to re-construct the facing edges. This should be done using a heavy duty fast cure repair mortar designed for industrial floor use. 

 

While cement materials are less expensive, they are brittle and ultimately fail becoming costlier in the long run due to the need for continual repair. 

 

A wide joint increase the risk of edge deformation and fracture caused by the deflection of the joint sealant under load. Consequently, it is important to minimise the width of the joint opening at surface level. 

 

Diamond Grind's method of repair (shown below) allows for a 50mm wide 'traditional expansion joint' to be replaced with a neat 5mm wide, fully sealed saw cut. Each repair is ground flush with the adjacent floor surface to ensure that wheeled traffic has a smooth transition over the repaired joint. 

 

Diamond Grind use the latest vacuum assisted systems and machinery to ensure there is no airborne dust created.

The Problem

Solid wheels and heavy loads transported by mobile plant cause major damage to the joint edge.

The Solution

New durable joint system provides a smooth surface for transition from one surface to another reducing maintenance costs.
