Pier and Abutment Repairs

For over three decades we have served the railroad industry by providing critical pier and abutment repairs above and below the waterline, without using cofferdams. This delivers significant cost savings to our clients by eliminating heavy equipment or the need to impede the right-of-way.

Concrete Repairs

J.F. Brennan Company’s portfolio of concrete repair methods offers several effective choices that can reduce cost and ensure a quality repair. Whether it is above or below the waterline, we can repair existing concrete, or place new concrete. Often, access to the damaged structure is difficult and requires innovative thinking to effectively transport and place concrete within a limited time schedule. At Brennan, we have mastered the challenging logistics of difficult placements around water-based structures.

It is often thought that a successful concrete repair must be done in a dry environment; however, this is not always the case. Brennan presents several methods of underwater concrete placement that best fit each project. Our teams of experienced divers can provide multiple underwater concrete repair options including: Preplaced Aggregate Concrete (PAC), formed cast in place concrete, pre-cast concrete, and pressure grouting.

Vinyl Sheet Pile Repairs

Vinyl sheet piling offers an alternative to underwater concrete forming. Its high-density polyethylene composition allows for a long-lasting, protective barrier between the water and the structure. Once in place, the sheeting is reinforced with a steel waler system and anchored to the existing structure. Preplaced aggregate concrete is then injected, or self-consolidating concrete is then placed behind the sheeting using the tremie method. Once completed, the vinyl sheeting and newly placed concrete creates a tough and aesthetically pleasing foundation for the structure.

Grouting Repairs

Pressure grouting is an integral part of Brennan’s geotechnical services. We often pressure grout to consolidate masonry bridge piers and increase strength lost to degradation. This can be done both above and below the waterline on several types of structures to restore integrity. Pressure grouting increases the bearing capacity, consolidates structure interiors, and arrests water infiltration.

Pile Jacket Repairs

Bridge and dock piling are susceptible to degradation caused by scour, ice flows, and time. Total replacement of the piling can be avoided by jacketing the piling to restore the piling to its original strength. A popular choice for pile bent repairs, this innovative technique to restore bridge and dock piling is cost-effective. Both concrete and wood piling can be repaired using this technique and the design is adaptable to client preference.
