EDYSTON, LLC delivers a quick and cost effective to solution to bringing life back to deteriorated concrete. EDYSTON creates a strong and dense concrete resistant to the damaging impact of repeated wetting, freeze-thaw cycles and salt damage. This results in extended service life of the concrete structure.

Individual EDYSTON products:

DURYGEL has been engineered to absorb deeply into the damaged concrete structure. Once inside, DURYGEL will optimize the pore structure by using impurities in surrounding concrete cracks to form a rejuvenating gel that creates a nearly impervious concrete matrix resulting in a longer life-cycle.

ENVYROGEL was developed to increase the deteriorated concrete's resiliency to environmental conditions. When applied, the ENVYROGEL technology bridges concrete cracks effectively manipulating the kinetics of alkali and hydroxide functionalization to create a protective or pacification barrier over corroded concrete, aggregate, and steel.

DENSYGEL has been developed to rejuvenate cracked and deteriorated concrete. This performance improvement leads to an increased service life, which lowers the structure's lifecycle cost for the owner.

Use and Application
  • EDYSTON is not a concentrate so do not add any water.
  • In order for EDYSTON to contact the deteriorated concrete, all coatings and contaminants must first be removed using ASTM D 4258, 4259, or equivalent methods. Condition the concrete surface to SSD before applying EDYSTON.
  • EDYSTON must be applied with an approved sprayer and/or applicator.
  • Apply EDYSTON at rate of 500 sf per gallon. A minimum of 3 applications are needed in all cases, but more may be required based on the amount of deterioration.
  • Alternate direction of successive applications.
  • Allow at least 10 minutes between applications, but do not let the surface visually dry. If the rate of drying does not allow this then utilize environmental protection or reschedule the application. Allow EDYSTON to cure for 24-hrs before applying a concrete surface sealer.
Storage and Packaging
  • Precautions must be taken to ensure that EDYSTON does not freeze, which can occur at 36 degrees.
  • EDYSTON has a shelf life of 5 years from the time of production when stored under controlled, laboratory conditions.
  • EDYSTON is available in 5 gallon buckets, 55 gallon drums, 500 gallon (1890 L) totes or by bulk delivery.
  • EDYSTON is not considered to be a dangerous material to handle. Before using, refer to the corresponding Safety Data Sheet for health, safety and environmental information.




Avoid contact with eyes, skin and clothing. Wash thoroughly after handling. Exposure may result in irritation of the skin, eyes or nasal passages from alkali in Portland cement. When wet, contact with the skin or eyes may result in irritation or burns.

Protect yourself with OSHA prescribed Personal Protective Equipment - OSHA 3267-09N-05.


In case of eye contact, flush immediately with plenty of water for at least 15 minutes and get prompt medical attention; for skin, wash thoroughly with plenty of soap and water. If irritation persists, get medical attention.
