how to repair cracks in basement concrete wall
Construction method:
1.Surface treatment
1)Seep away sundries such as base course all the loose concrete, dust, oil stain, saltpetering, contaminant etc. If repaired structure has already exposed steel bar.it need clean all the rust on the steel bar, and all the loose concrete.
2)Wetting the repaired structure surface, make it reach the state of saturation but don't flow.
2.Preparing material
TL-01 waterproof type repair mortar mix with about 18% clean water,mechanical stirring 3 minutes,
stop 3 minutes, then stir 3 minutes, until stir evenly.
3.Construction
1)Use brush coat a layer just tuned repair mortar on processed completed base surface.
2)Immediately use trowel forcibly scrap repair mortar on new painted still wet repair mortar coating,
and scrape it flat,Each layer thickness can't more than 25mm, construction layer by layer,finally repair
flatly by trowel.
4.Dosage
Per ton TL-01 waterproof type structure repair mortar can repair 0.5 cubic meters space.
5.Curing
Under normal circumstances, spray water curing 24 hours, in hot, dry and windy climate conditions, it
should cover repair surface to curing, in colder weather, use 40 degrees warm water to stir, then keep
warm and curing.
Testing data of TL-01 concrete repair material:
Inspection items | Unit | Technical requirement | Inspection result | Individual conclusion | |
Setting time | Initial setting | Min | ≥20 | 25 | Meet requirement |
Final setting | ≤60 | 50 | |||
Compressive strength | 4h | Mpa | ≥20 | 33.0 | Meet requirement |
1d | ≥30 | 42.1 | |||
28d | ≥50 | 72.5 | |||
Pull strength | 28d | Mpa | ≥2.0 | 2.7 | Meet requirement |
Expansion rate | 28d | / | 0.0%-0.1% | 0.02% | Meet requirement |
Product advantage:
1.Easily modulate, just need add water and stir.
2.Simple construction, can operate by nasonry tool such as scraper and ash knife etc
3.Strong coating adhesion, High compressive strength, Anti-freeze thawing, resistance to sulfate corrosion, non-toxic, non-corrosive.
4.Better sagging resistance, suitable for facade and superface operation.
5.Have protective property to steel bar, good durability, also have compact better waterproof anti-permeability.
6.Can be used in damp base course and damp environment as first-aid repair materials.
7.This product is basically the same with thermal expansion and contraction stress of concrete,
solve the defect that traditional epoxy mortar make basic concrete crack.
