Cement repair by epoxy injection
Cracks in cement are filled by injecting a low or high viscosity epoxy resin into the crack. The epoxy resin is injected under pressure which allows it to penetrate the full depth and path of the crack, providing a complete crack repair. Not only is the crack sealed, but structural strength is gained as the epoxy resin is much stronger than the original concrete.
Epoxy's high tensile and bonding strength prevents further elongation and yawning of structural cracks. However, the cause of the structural stress itself must be determined and resolved in order to assure proper repair.
Epoxy injection services can be provided on an array of bridges, buildings, storm drains, and many other cement structures.
Cement repair for Expansion Joint System
Expansion Joint Systems are used in locations where cement sealing expansion joints are required.
These systems are available with many different specification options depending on your needs and budget.
Expansion Joint Options
- watertight seals
- small movement
- large movement
- hardness variances
- multiple tensile strengths
They provide high expansion joint performance in locations such as parking structures, stadiums, plazas, sewage and water treatment facilities, concrete roof decks, and bridges. Cement expansion joints may also be used in large scale buildings and tilt up structures that require architectural patching in Montreal.
Horizontal and vertical expansion joint systems are available for wheel, foot traffic, and non-traffic areas.
Each expansion joint system is specifically selected for the particular application as the movement capabilities and requirements vary. Please consult with one of our Montreal cement repair contractors above for more information.
Polyurethane Grout Injection for cement repair – Montreal contractors explain how it work
Polyurethane grout injection service for the refurbishment of cement and masonry structures. Polyurethane grout injection is used to stop water infiltration and seal joints. There are two main categories of polyurethane grout injection products: hydrophobic and hydrophilic.
Hydrophobic grout polyurethanes are water-activated, cure to a constant volume, flexible, and are not affected by water or dryness. Characteristics such as these and the good adhesion employed on wet and dry cement make hydrophobic grout polyurethanes the product of choice for sealing infiltrating water in moist and wet applications with varying moisture cycles.
Hydrophilic polyurethane grout is also used for stopping water infiltration, however due to water being a component of the product’s chemical structure, unlike hydrophobic grouts, wet and dry cycles may cause the material to shrink and swell. Hydrophilic polyurethane grouts are cured upon reaction to water and are flexible.
Polyurethane grout injection is commonly used for stopping water infiltration and sealing joints in the following applications: defective cement, cement joints, limestone, brick, pipe intrusions, waste water tanks, drinking water reservoirs, reservoirs, sewers, manholes, tunnels in and around Montreal.
Cement Spall Repair
The term “spalling” refers to cement that has broken away from the rest of the slab. This is typically caused by moisture penetration corroding the rebar, causing a separation or delaminating of the cement.
In order to repair a spall, we must first remove all unsound cement from the spall area. After all the unsound cement has been removed, we clean or replace any corroded rebar. Next, the rebar is coated with a corrosion inhibitor and the spall is prepared with a bonding agent for the new patch material.
The final step is to fill the void with a high strength patching agent. Depending on the location and depth of the void, the patching agent may need to be applied in lifts, or steps. The contactors above have found that, given the correct application of products and conditions, the cement repairs will be at least as good as the original state.
