The expansion of the Oyster Creek propylene production facility in Freeport, Texas, was a key part of Dow Chemical’s multi-billion-dollar investment (Gulfstream) program to take advantage of low market prices for locally-produced shale gas. The massive scope of construction made easy application and reliability of the concrete treatment solution a priority. PENETRON ADMIX SB was specified as a robust waterproofing solution for all concrete used for the water containment tanks – each with a capacity of 1.5 million gallons (5.7 million liters). As an integral waterproofing protection, it prevents penetration of water and aggressive agents into the concrete and also features a self-healing capability. Delivered in pre-measured soluble bags, the admixture simplified accurate dosage during batching and saved time in the construction schedule.
