Marina Place Waterproofing and Structural Strengthening

Walker determined that the causes of the water intrusion were cracks in the stucco and exterior CMU wall, concrete spalls at windowsills, and poor sealant installation around windows. The water traveled through the cracks and spalls, down the hollow cells of the exterior wall CMU block, and under the unit flooring into the ceiling of the units below. Walker designed the recommended repairs and prioritized them as three separate projects, providing the condo association with potential costs for each project. The repairs could be spread across multiple years, with the major leak repairs prioritized first. As construction began, an additional issue was discovered. The exterior CMU block wall should normally have been reinforced with rebar to provide strength and resist wind loads, but no rebar was found. Walker recommended that this structural issue be addressed before the façade waterproofing work took place. Marina Place now has a properly installed, warranted waterproofing system that will protect the strengthened concrete structure and protect the building and owners' homes from water intrusion.
