Concrete Expansion Joint Repair & Sealing Service

Rebuild damaged concrete. Restore flexible seals. Minimize downtime.

Failed expansion joints can cause leaks, broken concrete edges, traffic hazards and recurring maintenance. Banks Industrial Group rebuilds deteriorated concrete and installs durable elastomeric seals to restore joint performance while accommodating movement.

Our hands-on crews use fast-curing Belzona polymer systems and other specialized materials to extend service life and minimize downtime. We serve industrial and commercial facilities throughout New Jersey, Pennsylvania, Delaware and New York. Applications include concrete tanks, chemical containment areas, underground vaults, warehouse floors and parking garages.

Extend concrete service life by rebuilding damaged edges and sealing out water and debris
Minimize downtime with fast-curing repair and sealing systems selected for your service conditions
Reduce recurring maintenance: Properly installed elastomeric systems provide a durable alternative to routine recaulking
Restore watertight performance: Seal joints to limit water loss, infiltration and damage to surrounding areas
Protect chemical containment with repair materials selected for the chemicals present
Accommodate joint movement while maintaining a flexible seal through expansion and contraction
Improve traffic safety by repairing broken edges that create bumps and trip hazards
Reduce equipment and product damage caused by forklifts and carts crossing deteriorated joints
Repair joints in any orientation: Use non-sag materials for vertical and overhead joint sealing

Why Expansion Joints Fail

Expansion joints must move while resisting traffic, weather, water and chemical exposure. Seals can tear, harden or pull away from the joint walls. Trapped debris can restrict movement, while impact, chemical attack and freeze-thaw cycles break down surrounding concrete. As damage progresses, leaks and rough edges increase maintenance costs, compromise containment and disrupt operations.

How BIG Restores Damaged Joints

BIG removes failed sealant and unsound concrete, prepares the bonding surfaces and rebuilds damaged joint edges with materials such as Belzona 4111. Restoring sound edges provides a durable foundation for the new seal.

We install flexible sealing systems selected for joint movement, orientation, traffic, immersion and chemical exposure. Depending on the application, options may include Belzona 2211 and 2221 elastomers and Belzona 4511 or 4521 expansion-joint sealants. These materials bond to prepared surfaces and flex with the joint, helping resist the tearing and separation that lead to recurring leaks.

Joint repair can be combined with concrete restoration and protective coatings to address deterioration throughout the surrounding structure.

Why Hire BIG?

Successful joint repair depends on correct assessment, material selection and installation. BIG brings these capabilities together to help your maintenance team resolve the problem and protect the asset.
