It is often thought that a successful concrete repair must be done in the dry; however, this is not always the case. Brennan can present several methods of underwater concrete placement to best fit each project. We specialize in underwater structures such as dams, bridge piers, retaining walls, and more. Whether it is in a cooling pond or under the ice during a cold winter, we can respond to a wide range of challenges.
Methods often used include:
- Precast Concrete
- Preplaced Aggregate Concrete (PAC)
- Tremied Concrete
- Pressure Grouting
Each method has been used to successfully repair and replace deteriorated concrete underwater. Through the use of several types of formwork, J.F. Brennan Company has successfully repaired ice-damaged, degraded, eroded, and broken concrete hidden below the surface of the water.
