How to repair a concrete driveway pothole
As for how to repair a concrete driveway pothole, we suggest you use our SC type
concrete repair material. This product is ideal because it can perfectly fill pothole,no
dry shrinkage cracks in new and old adhesion area.
1.It have better performance parameter when use SC material repair potholes in concrete driveway.
Test items | Unit | Technical requirement | Test result | Individual conclusion | |
Setting time | Initial setting | Min | ≥20 | 25 | Meet requirement |
Final setting | ≤60 | 35 | |||
Compressive strength | 2h | Mpa | ≥20 | 33.0 | Meet requirement |
1d | ≥40 | 66.1 | |||
28d | ≥50 | 90.5 | |||
Pulling strength | 28d | Mpa | ≥2.0 | 2.8 | Meet requirement |
2.When repair potholes in concrete driveway,SC type concrete repair material have 8 core advantages:
1)Achieved 1 h rapid open to traffic.
2)High compressive strength:2h>33Mpa,1d >60Mpa,meet requirement of rapid repair strength.
3)Good adhesion: Have super adhesion force with original concrete.
4)Good anti-crack property: Adapt to deformation of concrete base, and don't crack or fall off.
5)Good toughness: it is 5-8 times of normal concrete.
6)Expansion shrinkage coefficient is basically same with base course concrete.
7)Can be used in damp base course and damp environment as first-aid repair materials.
8)Simple and rapid construction.
3.Construction process of repair pothole in concrete driveway:
First: Joint-cutting
Second: Chiseling
Third: Cleaning
Forth: Mixing material
Fifth: Repairing completed
4.Matters Need Attention when repair potholes in concrete driveway:
1)Repair area should clean clearly by high pressure water gun,can't have any float ash.
2)Pavement should be wetted fully, until it no longer ooze water.
3)Repairing area should be washed clearly before paving, wet but can't have any water.
4)As far as possible to use mixer to mix repair material, control water cement ratio well. The mixed well repair material can't appear bleeding.
5)It can't construct when rainy day or temperature below zero.
5.Compared with concrete driveway paving asphalt to repair potholes,
SC concrete repair method have follow advantages:
1)Perfectly filling potholes,water difficultly to enter.If repaired by other way,
it still is broken slab,weak strength caused water easy enter into.
2)Nice color,color is same as original concrete road.
3)No dry shrinkage cracks in new and old adhesion area.
4)High adhesion strength,original concrete slab won't be broken.
5)Extend concrete road pavement service life.
SC concrete repair material is your good choice if repair potholes in concrete driveway.
Welcome for your inquiry. we ensure good repair effect.also save your time and money.
