Epirez Highway Patch Rapid Set Cement Patching Mortar 15kg

EPIREZ Highway Patch is a quick-setting hydraulic cement patching mortar designed for fast concrete repairs. It provides high early strength, high bond strength and precision non-shrink performance for repair work where rapid return to service is important.

Highway Patch is designed for concrete repairs in transportation, commercial and industrial environments. It can be trowelled or poured into the repair area and finished by brooming, brushing or trowelling.

The material can also be extended with up to 60% pea gravel measuring 6–10 mm. This provides an economical way to increase the volume of the repair material without the excessive voids, reduced workability or long-term durability deterioration described for other extended patching materials.

Key Features and Benefits

• Quick-setting repair mortar: Designed for fast concrete repair applications.
• Rapid strength gain: Develops high early compressive strength.
• Non-shrink performance: Provides 0.0% shrinkage according to ASTM C-827.
• High bond strength: Bond strength reaches 27.6 MPa at 7 days.
• High chemical resistance: Resists oil, grease, gasoline, salts and other listed chemicals.
• Up to 60% extension: Can be extended with 6–10 mm pea gravel.
• Wet/dry resistance: Provides resistance to wet/dry conditions.
• Freeze/thaw resistance: Provides resistance for demanding patching environments.
• Flexible finishing: Can be broomed, brushed or trowelled after levelling.

Where Can EPIREZ Highway Patch Be Used?

Highway Patch is designed for a range of fast concrete repair applications, including:

• Highways
• Bridges
• Sidewalks
• Airport runways
• Ramps
• Fast concrete repairs
• Footpaths
• Factory floors

Coverage and Kit Size

The 15 kg EPIREZ® Highway Patch pack provides approximately 0.6 m² at 12.5 mm thick.

Extending Highway Patch with Pea Gravel

EPIREZ Highway Patch can be extended with up to 60% pea gravel measuring 6–10 mm.

The extension is designed to provide an economical way to increase the repair volume without creating excessive voids or reducing workability and long-term durability as described in the product information.

Surface Preparation

Existing concrete should be thoroughly prepared before applying Highway Patch.

• Remove oil and other deleterious substances.
• Remove all unsound or damaged concrete until sound, clean concrete is exposed.
• Remove loose material by wire brushing, washing and/or an oil-free jet.
• Thoroughly saturate the concrete with water two hours before application.
• Remove standing water immediately before patching.

Mixing Instructions

Mixing and placement temperatures must be above 5°C.

1. Use a mortar mixer or suitable mixing paddle with a low-speed 400–1000 rpm power mixer.
2. Wet down the mixer and drain excess water.
3. With the mixer running, add the minimum recommended water.
4. Add EPIREZ® Highway Patch.
5. Mix for 2–5 minutes.
6. Add more water only if required, without exceeding the maximum specified amount.
7. Mix only the amount that can be placed within 10 minutes.

The water requirement is 1.5–2.0 L per 15 kg pail.

Application

EPIREZ Highway Patch can be trowelled or poured into the prepared repair area.

After levelling, the surface can be finished by:

• Brooming
• Brushing
• Trowelling

Do not place Highway Patch in layers and do not feather edge the material.

Strength Development

EPIREZ Highway Patch develops high early compressive strength, making it suitable for repair applications where early strength development is important.
