Project: CR 12A, Kemp Road over Creek, Havana, FL (FDOT Project T3388)
Product: 1125 lbs. 1” KV13 Basfiber® (125 CY at 9 lbs/cy)
Application: FRC Concrete Bridge Deck over Precast Prestressed Beams
This project used Basalt microfiber in a cast-in-place concrete bridge deck to prevent cracking due to creep and shrinkage in curing during early ages. KV13 Basfiber® in 1” chop lengths from Kamenny Vek was added to the dry components at the batch plant before any liquids. Preliminary testing at a dosage of 7 pounds per cubic yard yielded enhanced Flexural Tensile Strength (FTS) per ASTM C78 of 50% at 7-days.
FDOT officials requested an even higher dosage at 9 pounds per cubic yard which still mixed, placed and finished well, but did not substantially enhance performance and thereby confirmed the practical upper limit of 7 pounds for dosage. The standard FDOT mix was not altered in any way by the addition of the fiber.
The concrete was placed using a bucket and consolidated with vibrators to flow easily in place. Finishing was done with screed, trowels and a broom. The fibers stayed embedded and did not appear at the surface. Inspections at 3-months age showed no visible cracks anywhere in the exposed concrete deck.
Project: Balcony Topping, Ontario, Canada
Product: BasGrid™25
Application: Basalt woven grid in thin SCC topping over Hollow Core Plank
This senior assisted living residential building included two long outdoor balconies framed with precast, prestressed hollow core plank cantilevering from the building. A
topping was required to create a smooth even surface and to make sure water
drained away from the structure. The topping mix was placed varying from ½” to 2” thick. BasGrid™25 was chosen for its 1” open cell structure and paper- thin profile. The concrete finisher was able to lift the flexible grid with fingers to the proper location midway in the topping as the Self-Compacting Concrete (SCC) mixed was poured one pail at a time and the final surface was troweled smooth.
BasGrid™ provided temperature reinforcing that is non-metallic, so it will never
rust and spall the topping in the cold climate.

Melbourne Causeway Repair SR 500 / US Hwy 192
Melbourne Causeway Bridge Rehabilitation is an FDOT project, included in this project is the cathodic protection replacement and repair. This includes chipping away the piers cracked and damaged concrete.
The scope of this project is to repair or replace the cathodic protection on each pier and repairing the piers at the water level.
Our scope of the project is to attached the grids in the outer layer of concrete that come in contact with the corrosive water. As Basalt Grid is not subject to the corrosion as can be seen by using a steel product.
Check back for additional photos prior to the concrete being poured for a better look at the process.
