Product Description: Orco Blended Hydraulic Cement is a blended, fast setting hydraulic cement designed for plugging cracks, or holes in concrete or masonry where seeping water is a problem. The product may be used to make repairs under water. Due to its fast set, high strength and waterproof properties, it is used in a variety of applications. Uses: Sewers Fountains Underwater Concrete Piers Retaining Walls Concrete Pipe Anchor Bolts

Properties:

• Stop leaks instantly
• Sets in 3-6 minutes
• Ready to use-add water only

• Excellent pull out strength

Typical Test Data: Compressive Strengths:
One hour 1,000 psi
24 hours 2,500 psi
Seven days 4,500 psi
28 days 5,500 psi

Packaging: Hydraulic Cement is available in 50lb pails.

Coverage: 1 lb. of Hydraulic Cement will fill a void approximately 2"x2"x4".

Working Time: Working time is approximately 3-6 minutes with a hard set in 7-10 minutes. Times may vary due to weather conditions.

Preparation: Enlarge all cracks to 3/4" or larger by cutting square or with an undercut. Do not create a V shaped cut. If possible, relieve excessive hydrostatic pressure by drilling a relief hole in the crack at its lowest point. Clean surrounding areas and cavity. Dampen surfaces slightly prior to application.

Mixing: Mix with clean, potable water-4 parts Hydraulic Cement to one part water. Mix only as much as can be used in three minutes. Do not over mix or over water. DO NOT RE-TEMPER. In extremely warm weather, use ice water to slow down the set. In cold weather, all surfaces, product and water should be warmed to approximately 70 deg F.
Applications: Mold the putty like material with hands until it begins to warm and force it into the void and hold in place until set. The time required depends on hydrostatic pressure and temperature. Begin filling holes or cracks from the top.

Limitations: Do not apply when temperatures fall below 40 deg F. Do not use under base plates or for structural grouting.
