Life critical backup electrical systems for Marion Hospital lie below the block walls and roof of Marion Hospitals generator room. Water leaked in earlier this year and caused a $600,000 system to blow out. With another $5,000,000+ in equipment and lives on the line, waterproofing was required ASAP.
The general contractor, Dan Blough Construction, had received a specification for “waterproofing” using Dow Corning Elastomeric coatings. Central Coast Waterproofing was asked to bid the job using the specification.
Inspecting the job and reviewing the nitty gritty details in the spec, I realized that the Dow Corning product had serious limitations for this project. Multiple penetration in the CMU wall would prevent the elastomeric from being able to perform properly.
In discussions with the General Contractor and the Hospitals representative, we produced a specification for using Kryton Crystalline Waterproofing that was accepted. Once our contract was signed, the work was scheduled and completed in 2011.
Pressure washing the walls clean of dirt and contaminates, we then began applying Kryton T1 and T2 waterproofing by hopper gun to 2400 square feet of block walls and caps.
The Kryton was wet cured for 72 hours after application, whereby the crytals in the mix will grow into the concrete and seal the capillaries in the block wall, thereby waterproofing the walls.
Kryton requires no further maintenance, unlike the Dow product specifi
