Method Statement -Water Proofing
1.0 OBJECTIVE
OF PROCEDURE
This work method
statement covers the applying waterproofing for (your project's name).
This work method
statement provides information concerning method of application to ensure
compliance with contract requirements and drawings besides to perform safe
working environment and compliance with safety requirements.
2.0 DESCRIPTION
Estokote Grey is a cement based two component
polymer modified flexible waterproof coating. When used in reservoir or similar
structure, it is able to accommodate the bending moment of the structure when
it is filled with water. It fills and seals pores and voids of concrete or
Masonry Surfaces to prevent water infiltration.
It is compatible to concrete. The bonding agent
imparts excellent adhesion to concrete surfaces and forms part of the
structure.
Packing :
22.5 kg pack
Coverage :
11 m² per pack per two coats

METHODOLOGY
v Preparation
a.
The
surfaces, which are to receive Estokote Grey coating, must be free from oil,
grease, wax, dirt or loosely adhering particles and sharp edges or any other
form of foreign material, which might affect adhesion. The surface must be
roughened.
b.
Spalled
and deeply disintegrated concrete should be removed to sound concrete and
repaired with a suitable concrete repair mortar.
c.
Absorbent
surfaces have to be thoroughly saturated with water prior to application of
first coat of Estokote Grey. However, no loose standing water should be on the
surface before application.
v Mixing
a.
Mix
in a clean container by slowly adding the powder component to the liquid
component.
b.
Stirring
with slow speed mixer for 2 – 4 minutes to avoid lump formation.
c.
Use
mixture within 30 minutes.
d.
Do
not add water.
v Application
a.
Whilst
the substrate is still damp from saturation, apply the first coat.
b.
Leave
to harden for approximately 4 – 8 hours at temperatures above 20°C before
applying the second coat.
c.
Re-mixed
the Estokote Grey material remained in mixing vessel for every application of
Estokote Grey.
d.
For
floor application, to avoid risk of damage to the first coat, it is recommended
that the second coat be applied before 24 hours.
e.
If
the second coat is applied 12 hours or later, the first coat shall be slightly
pre-wetted, preferably using a fine spray.
f.
After
the second coat has been applied, better finishing can be achieved by rubbing
down with a soft, dry sponge.
g.
Floor
screeding inside the water trough to be done before waterproofing applied.
v Over
Coating
a.
Allow
the coating as above to be hardened for at least 3 days prior subsequence over
coating work.
v Protection
a.
The
freshly applied waterproof coating shall be protected from rain, dirt, oil
grease or other loose materials during its drying time.
b.
The
contractor should also take precautions to protect the Estokote Grey coating
from any mechanical damage during the construction of other trade of works.
v Curing
a.
Precaution
should be taken for applications done directly under sunlight and windy
conditions. It should also be protected from direct rain for at least 4 hours.
b.
The
finishing coat shall be cured for 3 – 5 days before other trade shall be
proceeded.
v Ponding
Test
a.
The
waterproof area has allowed to be cured for hours before ponding test was
carried out for 24 hours duration.
b.
If
the ponding test was failed, rectification work shall be carried out and after
the rectification work was done, the ponding test will be carried out.

OF PLANTING
5.1
Site Preparation
The Main Contractor is required to grade the planting
area to finish grades and allowed for a smooth and uniform to the consultant
approval. The Main Contractor is required to roll, scarify, rake and level so
to obtain the even planting area. All loose stones, gravel, tree stumps in which
is not desirable is required to cart away from site to the approved dumping
area. To lay 50mm thick layer of approved black vegetable soil / top soil
