Pier and Abutment Repairs

Concrete Repairs

Nelosca Technologies’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 Nelosca, 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. Nelosca 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.

Grouting Repairs

Pressure grouting is an integral part of Nelosca’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.
