Background technology
No matter basement or roofing or toilet are required for setting waterproof to building, according to waterproofing grade design requirement
Number is set up defences using corresponding and different kind of material carries out waterproof or moisture-proof.Although waterproofing work budget only accounts for construction budget very
A few part, but its effect is but extremely huge.If not carrying out building waterproof processing, basement, roofing can leak, and defend
Between life, kitchen all can leak, this not only upsets the normal life, work, orders of life of people, but also directly influences whole and build
Build the service life of object.
With the high speed development of capital construction cause, construction waterproofing engineering technology and various waterproof new materials, new process
Exploitation is also continued to bring out with application.But current waterproof system still has some problems, and waterproof is caused to fail, specific reason
Have：
1, the waterproof effect of waterproof roll is bad
Show that requirement of the waterproof roll to formation level is high first, if base surface out-of-flatness or peeling, dusting, contained
Water rate is too high, will have a direct impact on coiled material and the bond effect of base, and coil waterproof layer is caused to generate drum alice phenomenon.Followed by
On showing the cohesive force of waterproof roll and formation level not enough, general waterproof roll only has physics with cast-in-place concrete bottom plate
Mortise and tenon active force be easy to cause the bonding failure of basal plane and coiled material, generates interlayer string water drainage.It is that market is common anti-again

Connection transition position be closely bonded completely, bring leak, water of leaping up hidden danger；If using traditional polyurethane water-proof paint,
Polymer waterproof coating material, hot melt ointment etc. are smeared at node, it may appear that water-repellent paint and all kinds of material bad adhesions, it is moist,
Moisture surface can not bond, and these coating are incompatible with big face waterproof roll material, easily be detached from layering, there are very big percolating waters
Hidden danger.
According to analysis, the generation of the leakage problems of waterproofing work 90% is all to be happened at few position of joints, at coiled material lapping
Equal positions.Because traditional waterproof system belongs to shading type waterproof, can be played in the case of no breakthrough preferable anti-
Water effect, but big face waterproof layer breaking point once occurs or overlap edge is not firm, and position of joints handles leakiness, just will appear
Broken some leakage is a piece of, directly affects entire waterproof system, causes waterproof failure.
