Composite construction methods for non-curing waterproof coatings and coils

Non-cured waterproof coating and coil composite use, compared with the traditional coil waterproofing, in the construction method, construction conditions requirements, construction time and other aspects of the advantages, can greatly reduce the construction time, reduce the impact of construction on the environment, as well as reduce leakage due to construction defects, so it is widely used in modern building roof and basement and other parts of waterproof. So non-cured waterproof coatings and coils this compound practice should be how to carry out construction?construction preparation(
1
) grass-roots surface. The base surface of the wall should be solid, flat, clean and dry, and the concrete surface should not have honeycomb, holes, prominent rebar head and template seams. If it does not meet the requirements, it should be leveled again.
the outer wall through the wall tube should be fixed firmly, the yin and yang angle of the substation should be
50
×
50mm
angle.

) on-site storage requirements. Materials should be light, and in accordance with the requirements of the specifications, in the field to choose the right place to store materials, materials should avoid direct sunlight and low temperature on the material caused non-human injury. Do not stack the material on multiple layers and try to avoid pressure deformation.Construction process grass-roots acceptance→ grass-roots treatment→ brushing grass-roots treatment agent→ hot melt non-cured rubber asphalt waterproof coating→ brushing non-cured rubber asphalt waterproof coating →painting self-adhesive waterproof coil → roll mechanical fixation→ node treatment→ sealing, sealing→ waterproof layer self-inspection, repair → acceptance.
grass-roots treatment: the grass surface should be strong, flat, dry, clean, dust-free oil, corners should be made into
50mm
×
50mm
angle or radius
50mm
fillet.
Brushing grass-roots treatment agent: in the qualified grass-roots even brushing grass treatment agent, brushing should be fully stirred before the treatment agent, brushing should be thick and uniform, do not leak bottom, do not accumulate, follow the principle of first high and then low, first facade after plane. Self-adhesive coils can be applied when the brushed base treatment is dry.
hot melt non-cured rubber asphalt waterproof coating: before construction, the non-cured rubber asphalt waterproof coating should be placed in the heating tank heating liquid state, to reach the specified heat temperature can be constructed, manually scraped heating temperature ≥
120
degrees C, spraying temperature ≥
150
degrees C.
construction non-cured rubber asphalt waterproof coating: the heating tank of non-cured rubber asphalt waterproof coating with scraping or spraying methods evenly scraped on the grass, thickness
1mm
can be, scraping non-After curing rubber asphalt waterproof coating
3min
rolled self-adhesive waterproof coil, and then light scrape the surface of the coil material, drain the internal air, so that the coil material and non-cured rubber asphalt waterproof coating firmly bonded together.
Roll self-adhesive waterproof coil: in the non-cured rubber asphalt waterproof coating on the grass after painting, immediately roll self-stick waterproof coil, roll when gently scraping the surface of the coil, drain the internal air, so that the coil and liquid rubber firmly bonded together.
self-adhesive waterproof coil lifting width of
80mm
, the narrowest place must not be less than
70mm
, the joining edge application roller rolling pressure tight.
the coil is pasted, the coil should be fixed immediately with steel nails or expansion screws, fixed position from the edge of the coil
10mm
, spacing
500mm
, and covered by the coil.detail node processing:through the wall tube: through the wall pipe root should be ash treatment, and painted non-cured rubber asphalt waterproof paint, and then with self-mucous film waterproof coil wrapped, sealed tightly. Each wall-to-wall tube is not less than
250mm
.
reserved turn-over treatment: reserved turn-over for the basement exterior wall waterproof key treatment site, but also the basement leakage of the most vulnerable parts, if not handled properly will cause serious leakage hazards.
waterproof coil seal head: the coil seal is fixed with metal pressure strip and steel nails, and then sealed with sealing paste. The coil receiving port should be 500mm
above the

work can only be carried
out
the non-cured rubber asphalt waterproof coating melts into a liquid state and reaches the specified thermal temperature.
(

) scraped non-cured rubber asphalt waterproof coating at the same time rolling self-stick waterproof coil, pay attention to the bonding effect of the coil joint edge.
(
4
) coils should be mechanically secured to prevent the coils from falling off during construction, and the fixing nails should be covered by the coils.

) reserved for the tip area of the self-adhesive waterproof coil self-adhesive layer and the self-adhesive layer with hot melt heating and bonding tightly. quality acceptance
(

) coil tie edge should be all checked, all joining edge should be bonded firmly.
(
2
) coils and non-cured rubber asphalt waterproof coatings have a adhesion rate of ≥
90%
.
(

) waterproof construction is completed, no coil or non-cured rubber asphalt waterproof coating and grass-roots cracking and other phenomena.
(
4
) self-adhesive waterproof coil has a lift width of
80mm
. Product Protection and Safety Precautions (
1
) Waterproof engineering construction should have specific measures for waterproofing the finished product of the operation, the operator shall not arbitrarily destroy the finished process at the construction side. After the completion and acceptance of the project, there should be a person responsible for maintenance and management, strictly prohibited after acceptance of drilling holes, holes, damage waterproof layer.
(
2
) coils are laid and exposed directly to sunlight for more than three weeks, cover protection should be provided with plastic sheeting or other materials.
(
3
) civil works backfilling soil, the site reserved two waterproof construction personnel to track the whole field, once found waterproof layer damage, immediately repair.
(
4
) backfilling soil should be layer backfilling, layer by layer solid, strictly prohibit the emergence of one-time dumping and other phenomena, backfilling soil is prohibited to contain construction waste, stones, concrete blocks, etc., once the above phenomenon is found, construction personnel should immediately stop, and with the civil construction side, supervision side to negotiate.
