Our product is designed to be used in conjunction with PHC and is not intended for standalone use. It is designed to wrap around PHC to prevent moisture from seeping in, allowing for better product performance

De-bonding foam
| NAME |
REMARKS |
De-bonding foam
for vertical reinforcement anchor bar |
There are five sizes with a diameter of 16-40m |
How the PHC Works
1. The bonding between concrete and steel is removed by covering all reinforcement bars with de-bonding covers.
2. The PHC that is installed with the water in the concrete and expand. The expansion will cause stresses in the concrete that has set. The expansive stresses will exceed that of the compressive stress of the concrete after 3 to 4 days and hence causing a crack in the pile head.
3. The cracking of the pile head at the position of the PHC will hardly propagate below the intended cracking line.
Components
1. PHC
a) Type ES-35mmWx600mml
b) Type S-45mmlWx700mml
c) Type B-70mmWx550mml
2. Steel Reinforcement De-Bonding Covers
Various sizes - From Φ16mm to Φ40mm
3. Steel Brackets
a) Type ESB
b) Type SB
c) Type BB
d) Type DBB
4. Plastic bag
a) 5C-W130mm-L1100mm
b) 5C-W140mm-1400mm
Installation Procedure
1. The PHC materials are fixed to the steel Reinforcement cage prior to lowering the cage into the bored hole for concerting.
2. The PHC are initially fitted to the steel brackets.
3. The steel brackets are then fixed to the steel reinforcement cage,with the PHC at the level that the crack should form in the pile head.
4. Install de-bonding covers to all the steel Reinforcement starter bars above the PHC.
5. The installation of the PHC is complete and ready to be installed into the bored hole for concreting.
Pile Head Removal
1. After concreting, wait 4 to 5 days for crack to form at the pile head.
2. When the crack at pile head has formed, the pile head can be removed by lifting it off with crane, when necessary with the aid of an excavator.
