USES
CHEM-CRETE TUNNEL SYSTEM is used to encapsulate concrete in overhead and vertical applications. CHEM-CRETE TUNNEL SYSTEM can be used above or below grade.
APPLICATION
Limitations: Do not apply CHEM-CRETE TUNNEL SYSTEM if ambient and surface temperature is less than 38○F (3○C). Do not commence fogging until initial set has been reached; typically, 1 – 2 hours depending on the ambient conditions. The product should be conditioned to between 40○F (4○C) and 95○F (35○C) before use.
Surface Preparation: All surfaces must be clean and free of dirt, dust, paint, sealers, coatings, loose material, adhesives, curing compounds, or any material that inhibit CHEM-CRETE TUNNEL SYSTEM from coming in contact with the concrete pores. Removal of any anti-adherents or loose materials must be accomplished mechanically. For proper adhesion, the concrete must have fractured aggregate profile.
Dampen the surface thoroughly with clean water. Avoid standing water.
Application Equipment: CHEM-CRETE TUNNEL SYSTEM can be applied with dry shotcrete equipment. No water is to be added unless in the nozzle of the shotcrete application machine. Contact our company for more information on application equipment.
Water Consumption: 100 Lbs. of CEHM-CRETE TUNNEL SYSTEM will require 18 to 20 Lbs. Water.
Setting Time:
Initial set is 45 to 50 minutes
Final Setting: 50 to 55 minutes
Application Thickness: minimum recommended is ¼ inch.
Coverage: a 55 Lb (25 Kg) Bag of CHEM-CRETE TUNNEL SYSTEM will yield approximately ½ cubic foot (14.16 Liters).
Curing: the formulation of CHEM-CRETE TUNNEL SYSTEM minimizes the need for curing. However, application in direct sunlight or windy conditions may lead to rapid surface drying. The use of light water fogging for 48 hours or a water-based curing compound that complies with C-309 is recommended.
Cleaning: clean all mixing and application equipments with water immediately after use. Remove all splatter of spills with water before material sets.
STORAGE
CHEM-CRETE TUNNEL SYSTEM should be stored in dry area away from direct sunlight. When properly stored, CHEM-CRETE TUNNEL SYSTEM has a shelf life of 24 months in its original unopened bag.
SAFETY
CHEM-CRETE TUNNEL SYSTEM is a non-flammable and non-toxic in nature. Avoid contact with eyes and skin as it may cause irritation due to its alkaline nature. Splashes of CHEM-CRETE TUNNEL SYSTEM should be washed off immediately with clean water. Wear necessary safety goggles, gloves and dust mask. Keep container closed when not in use. Keep out of reach of children. This product is for industrial use only by qualified technician. Consult the material safety data sheet for further health and safety information.
