DESCRIPTION: |
| CRACK WELD is a two
component epoxy adhesive designed for injection into
nonmoving cracks in concrete. Formulations range from
extremely low viscosity, to materials that may be
injected into concrete that is underwater, to very
flexible, rubber-like compounds.
CRACK WELD GP - General
Purpose, low viscosity, high strength.
CRACK WELD LMF - Low
modulus, very flexible.
CRACK WELD XLV - Extra
low viscosity, high strength. |
|
USES: |
|
Injection
of cracked concrete, and wet or underwater cracks in:
Precast Members, Retaining Walls, Piers, Roads, Bridges,
Beams & Columns, Pilings, etc. |
|
ADVANTAGES: |
| 100% solids, conforms
to VOC regulations.
Moisture insensitive.
Various viscosities.
Various hardness. |
|
SURFACE
PREPARATION: |
| Crack should be free of
dust residue. If the material is to be injected, install
injection ports at appropriate intervals along the crack
to allow for full depth penetration. Use DBA-5 or DBA-30
to install entry ports and to seal the surface of the
cracked concrete. Injection can start once DBA-5 or
DBA-30 is sufficiently cured. |
|
MIXING
AND APPLICATION: |
|
CRACK WELD
can be injected into cracked concrete using a two
component positive displacement injection machine or two
component cartridge. CRACK WELD may also be hand mixed
and poured into horizontal cracks. |
|
LIMITATIONS: |
| Do NOT allow the
product to freeze.
Do NOT apply when
temperature is below 50°F.
Do NOT apply to latex
modified mortar or concrete. |
|
CLEAN
UP: |
| Clean tools and
equipment immediately with a suitable solvent such as
xylene or lacquer thinner. |
