Trước khi thi công xây dựng, công việc quan trọng nhất đó là chống mối. Tôi xin gửi các bạn phương pháp chống mối.

1. ANTI-TERMITE TREATMENT
I. THE IMPORTANCE OF THE ANTI-TERMITE
Vietnam is a country which located in tropical, hot and humid environment. It is suitable
for development of insect, especially the kind of termite activity for all time of year cause serious
damage to the building was built.
Termites are social insects, live in corporation with hundreds of thousands the number of
individuals. Given the potentially cross-mortar perforated wall (by acids in the mouth with the
original base effect in lime) with the ability to operate day and night tirelessly fertility huge (a
queen can lay over 36,000 eggs / day). Termites really has become a major threat to the
architecture of people on the ground. Especially building have used many items, wooden items
such as mold, the door, filing cabinets, document ...
Previously, due to fully experience the harmful effects caused by termites, many buildings
untreated termites from the foundation. So a lot of work put into use recently got termites attack
and cause serious damage.
From this situation, in 2008, the Ministry of Science and Technology has announced
National Standard 7958: 2008 - Anti-point for the project started construction. Under this
standard, the building dating from the expiry of 50 years or more are required to be handled
termite right from the beginning of construction.
Project: Proposed Factory Building for Linea Aqua (PVT) Limited, at Viet Nam is one of
the expiry dating for years, was built on the ground there are many remnants of plant (roots,
stems, leaves ...) inside have used a lot of furniture (cabinet documents, tables, chairs, mold, the
door ...) - this is the favorite food of termites, termite so handling is a necessary job, to protection
works to avoid the risk of being undermined by the attack, invasive of soil termites (threat -
Marcrotermes sp) and the hub (damp wood termites - Coptotermes Fomusanus Shiraki) in tropical
climates hot humidity of Vietnam.
II. SPECIFICATIONS AND WARRANTY
1. Requirement
 It prevents the penetration of long-term damage to the relationship works.
 The chemicals used must be allowed to be used in Vietnam in 2013 (the drugs listed in the
List of Plant Protection permitted, limited use in Vietnam in 2013).
 During and after use, handling termite do not adversely affect the landscape and surroundings.
2. Warranty: 12 months.
III. HOW TO INTRUSION OF AFFILIATION
There are 3 ways of termite to penetrate the building:
1. Infiltration emerges from the ground and from the neighborhood: This is the most common
intrusive and most common. According to enter this connection will be available from the
termite nest construction background or from the surrounding areas from entering the system
through the dirt road (roof line) continuous connection to the place from termites food source.
2. Infiltration by air: ie the bond maturity (approximately 3.5 to 4 years of age), they grow wings
and fly out group (also known as the cocoon phenomenon - often appear when raining or with
thunderstorms). After falling off, one of the pair bond will pair up and get into the secret
places like the door mold, damp areas ... on the floor to establish new termite nests.
3. Infiltrate transmitted infections: ie termites from entering the building through the transport of
infected items have links such as tables, chairs, beds, cabinets, door frames ... from one place
to another man.
IV. TECHNICAL SOLUTIONS ANTI – TERMITE TREATMENT
3 ways intrusion mainly as above, for the treatment of highly effective against termites,
construction units to prevent the entry of termites streets inside the building. Specifically, will
include the following steps:

2. 1. Clean the site
 When leveling the ground, if termites are found to be dug to hold. Then, using about 20-25
liters of drugs Lenfos 50EC (1.2% solution) irrigation in place to eradicate termites entire
termite system works in the background.
 For crop residues such as wood chips, formwork, wooden beams ... it prior to processing, must
be collected and brought clean destroyed. In the case of wooden formwork stuck without
being removed, they must conduct Lenfos 50EC spray solution (1.2% solution) effect
relationship in that room to disable feed and where inhabited by termites.
2. Treatment underground termite barrier outside work, as the following steps:
 Step 1: On the field adjacent to the outer part of the wall, dig a deep 10cm soil layer, 50 cm
wide, forming trenches run continuously and closed circumferential wall outside the building.
 Step 2: After trenching is done, proceed to create the hole with a diameter of 1-2cm, 30-40cm
deep, hole number 20 / m2 trench.
Arrangement borehole: Creating 3-row drill holes along the trench. First row from holes to
foundation wall by 5cm, every second row hole from the first by 20cm (every second row
hole to run staggered with every first and third holes), every third row holes from every hole
second hole by 20cm.
 Step 3: After creating the hole, spraying liquid termite Lenfos 50EC drugs are on the surface
trenches. Norm infusion termite Lenfos 50EC: 6 liters / m trench.
 Step 4: Fill in trench termite soil. When backfilling surface barrier against termites outside,
use repellent solution sprayed onto the hub Lenfos 50EC proud again.
 Step 5: Compaction surface trench refill the original surface.
3. Treatment underground termite barrier inside the building, as the following steps:
 Step 1: On the ground adjacent to the inner part of the wall, dig a deep 10cm soil layer, 30 cm
wide, forming a continuous trench run and closed around the wall inside the building.
 Step 2: - After trenching is done, proceed to create the hole with a diameter of 1-2cm, 15-
25cm deep, hole number 20 / m2 trench. Arrangement borehole layout: Create two drill holes
along the line trench. First row holes from 5cm to foundation wall, every second row hole
from the first to 20cm (every second hole with a hole to run staggered first).
 Step 3: After creating the hole, spraying liquid termite Lenfos 50EC drugs are on the surface
trenches. Norm infusion termite Lenfos 50EC: 5 liters / m trench.
 Step 4: Fill in trench termite soil. When backfilling surface barrier against termites inside,
using liquid repellent spray on your face relationship Lenfos 50EC proud again.
 Step 5: Compaction surface trench refill the original surface.
4. Treatment the termite at ground floor
 Before the unit construction finish, use the drug solution termite repellent spray Lenfos 50EC
are on the whole area of black sand embankment compaction (if any) of the 1st floor
 The infusion rate termite Lenfos 50EC: 2.5 liter / 1m2.
5. Treatment the termite at special areas
In addition to the items above, if the work has drainage pipes, underground wiring ... to
interrupt the continuity of the relationship generous, it must be treated immediately with
additional smoking connections according to the norms of generous clues inside and outside as
mentioned above.
V. EXECUTION PROGRESS
Progress of anti termite treatment depends on the progress of construction of the building
contractor. Therefore, the execution of anti termite treatment and the construction must be closely
coordinated with each other. Building Contruction progresses to where the progress of anti termite
treatment also be deployed immediately to it. Typically, the treatment is started when the
construction complete the foundation wall work of the 1st floor of the building.
