CASE STUDY
This is a raft foundation which will support the plan of building the Jakarta Tower which is the tallest building in Indonesia.
Problems arise when the casting took place not accompanied by subsequent curing process, causing a rift structures patterned as rebars pattern underneath.
This leads to concrete and concrete becomes monolith.
CRP measures to do is:
1. Identify the type of damage.
2. Perform initial cleaning.
3. Installing nipple with epoxy bonding agent material: Nitobond EC.
4. Replacing the seal also with epoxy bonding agent material: Nitobond EC.
5. Once installed, then the wind is blown through the nipple injection using electric-powered compressor.
6. Then epoxy injection material: Conbextra EP10TG injected by means of LPI (Low Pressure Injection) with blown from the compressor.
7. For cracks that area moist or waterlogged, we use injection material: Conbextra EP10D designed for damp and wet areas.
8. After completion of the injection process, and the seal attached nipple cleaned with a diamond grinder.
