EXPANSION JOINT &

LEDGE BEAM REPAIR

We are a Toronto-based company specialized in injecting expansion joints from the inside, which makes it unnecessary to excavate podium roofs of underground parking garages.
We repair floor, wall, and ceiling expansion joints, including those located behind ledge beams.

OUR SERVICES

 

Concrete Expansion Joint &
Ledge Beam Repair

Expansion joints – spaces between concrete slabs – play
an important role by allowing concrete to expand and contract up to four inches in total.
It is necessary to waterproof expansion joints when they
start leaking, to prevent concrete degradation.

We repair concrete expansion joints and ledge beams, offering lasting waterproofing solutions.
Parking garage expansion joint repair and joint injection at medical facilities are some of our specialties.

Lasting Repair Guaranteed! 

Our specialized industrial-strength materials have been tested to the MTO standards to last 15 years, which ensures durable waterproofing.
 

APPLICATION BENEFITS

Why Expansion Joints Leak

Expansion joints located in podium roofs of parking garages can start leaking when the waterproofing membrane fails, and the roof has cracks. Water will run through the cracks into the joints, making its way inside the P1 level of parking garages, degrading concrete surfaces.

Water can leak through to the next underground levels (P2 and on) if the floor expansion joints of the P1 level and / or the traffic topping have failed, and the floor has cracks.
Water can also enter through the rampway if the trench drains are not working properly, or be brought in by vehicles in the form of snow.

Wall expansion joints can fail due to age and wear-and-tear, becoming less elastic and cracking. If the joints are located in the external walls below grade, water from the environment will leak through the cracked joints or through cracks in the wall slab.

Our Solutions

Efficient Repair Methods

Negative-Side Injection

Our specialized application methods allow us to inject liquid rubber directly into the expansion joints, from the bottom, ensuring efficient podium slab waterproofing. This brings great savings – no excavations (when repairing joints in the podium roofs of parking garages), and no extensive area closures.

Ledge Beam Repair
Concrete expansion joint repair can be part of ledge beam waterproofing. By injecting the expansion joints located behind ledge beams, as well as restoring the beams through crack repair and patching, we prevent water from infiltrating and degrading ledge beams, which could cause them to lose their load-carrying capacity.

Our Solutions

Expansion Joints in Medical Facilities

Zero-VOC Materials
Smooth finishes of interior expansion joints are vital for patient comfort and equipment transport. No odours are emitted during the repair process.

Noise & Dust Control
Temporary enclosures are used to control the dust generated during repairs. To minimize the impact of noise, most of the work is carried out during off-peak hours.

 

Minimal Impact on Operations
As a self-managed company, we do careful monitoring throughout the repair process and provide continuous updates on our progress.

Application Benefits

Cost & Time Savings
Our specialized materials enable us to repair expansion joints from the negative side, making it unnecessary to excavate parking garage podium roofs. Thanks to this less invasive method, materials, time, and labour are saved.

 

Permanent Crack Sealing
Thanks to monolithic adhesion provided by our products,
we seal concrete expansion joints and cracks in the concrete slabs around the injection. Our materials bond instantly, while allowing concrete slabs to expand and contract, providing durable expansion joint waterproofing.

 

Zero-VOC Materials
When working in medical facilities and other VOC-sensitive areas, we waterproof expansion joints with zero-VOC materials that do not impact hospital and clinic operations.

REPAIR METHODS

Ceiling Expansion Joints

To repair a ceiling expansion joint, a multi-step procedure is followed. It involves expansion joint cleaning, application of adhesive, and insertion of a backer rod before the injection
is done.

Wall Expansion Joints

Wall expansion joint repair requires a similar procedure, but involves two backer rods – one on each side of the joint, to ensure the injected material remains in place.

Floor Expansion Joints

Floor expansion joint injection is done by following
a procedure similar to ceiling expansion joint repair, with one minor difference – the backer rod is placed at the bottom of the joint.

Ledge Beam Repair

First, we determine where the expansion joint is and then drill through close to 40 cm of ledge beam concrete.
Once this injection port is ready, we waterproof the expansion joint through injection.

FAQs

Q - Causes for Expansion Joint Leaks

Q: Why are the expansion joints in our parking garage leaking?

A: Such leaking is caused by water infiltrating from the environment through cracks in the waterproofing membrane (that covers the joints) and the garage ceiling.

Q - No Excavation Needed

Q: Is it necessary to excavate to repair expansion joints in a parking garage?

A: No. We don’t excavate podium roofs of underground parking garages because our specialized methods and materials allow for injection to be done from inside.

Q - Ledge Beam Repair

Q: Is it possible to repair ledge beams?

A: Yes. We drill through up to 40 cm of ledge beam concrete to allow the injection of the expansion joint behind the beam, which is made possible by using our innovative liquid rubber materials. We also repair cracks and install patches on the ledge beam, if needed.
