Kenapa berlaku masalah kebocoran di siling rumah:
Perkara seperti ini sering melanda kepada pemilik rumah lama ,tapi rumah baru pun ada berlaku sedemikian, kenapa?
Biasanya faktor bumbung :Pengubahsuaian rekabentuk yang tidak sesuai mempengaruhi sistem pengaliran air yang turun diatasnya.
Keretakan concrete, berlaku juga pada bumbung rumah yang dibina dengan menggunakan cara concrete slab gutter ,kebiasaannya sukar untuk mengenal pasti tempat berlaku kebocoran yang tepat.
Genting : Berlaku akibat keretakan pada alur genting atau genting pecah, kerosakan genting biasanya berlaku sewaktu pemasangan dimana pijakan tukang sewaktu bekerja .Berlaku juga jika terdapat objek terbang sewaktu ribut. kesukaran mengenal pasti tempat berlaku bocor yang sebenar terjadi jika ada pemasangan aluminium foil di bawah atap,sebab halangan ini memberi kesan besar mengenal pasti tempat sebenar yang bocor ,cara mengesan spot bocor yang terbaik ialah dari dalam siling kerana terdapat cahaya menembusi dibawah bumbung. Jika atap genting adalah pemasangan baru ,berlaku kebocoran mungkin di sebabkan kecerunan atap yang rendah,dimana bila hujaan terlalu lebat desertai angin yang kuat akan menolak air yang turun naik keatas atau disebut reverse flow. jika selisih atau cerun atap rendah maka mudah lah air menitis kedalam siling rumah.
|Concrete Gutter Lining System
Our system for treating concrete gutters on domestic properties combines a lining system impervious to the movement common with this type of construction. We also offer a high quality flexible white coating for the exposed outer surface of the gutter.The various stages of treatment are detailed below.
Most concrete gutter have been coated with waterproofing material at some stage in their life these generally only last two or three years. If they have not been treated the old oxidised bitumen coating is so brittle it has cracked and de-laminated. For proper treatment we have to remove at least the first three rows of tiles to remove all of the old coatings. In 99% of cases the old sarking felt has rotted away and if still present can be crumbled by hand. The two lower lines of battens are generally rotten and require replacement.
As most homeowners with poured-in-place concrete foundations can attest: Cracks in basement walls are a fact of life. These cracks due to drying shrinkage, thermal movement, and other causes usually are minor and result in few problems. But over time, even minor cracks can grow larger and cause big headaches, such as loss of structural integrity or, more commonly, water leakage.
The good news is that in most cases homeowners can now have these cracks fixed permanently without the need for costly, disruptive excavation using low-pressure injection of epoxy or polyurethane foam repair materials.
Most basements eventually leak. “Even if a crack is not leaking now, eventually water will find it,” says Lou Cole, president of Emecole Inc., Romeoville, Ill., a manufacturer of epoxies and polyurethane foams for all types of foundation crack repair. Cole says that in the Midwest, crack injection has been an accepted way of tackling these repairs for many years, and more and more foundation repair contractors around the country are adopting the technique because it is cost-effective, reliable, and permanent.
“Emecole’s customers, primarily residential waterproofing contractors, have less than a 1% callback rate for crack repair work. More than 99% of the time, crack injection will fix the problem,” says Cole. “Most contractors in the Chicago area (as well as other parts of the country) warranty the injection repair for the life of the structure,” he adds.
Cole launched his company in 1987, after coming up with the concept of dual-cartridge dispensing of two-component materials using a spring-assisted dispensing tool similar to a caulking gun. The application that seemed to show the most promise for his dual-cartridge system was low-pressure injection of cracks in concrete. That gave him the impetus to develop a line of epoxies and polyurethane foams specifically formulated for those types of repairs.
The whole purpose is to fill the crack, from front to back, with epoxy or polyurethane. “For basement walls, low-pressure injection is the best way to ensure that the crack is completely filled,” Cole maintains. This method is effective for filling cracks 0.002 to 1 inch wide in walls up to 12 inches thick. It can also be used to fill cracks in concrete floors and ceilings
There is also the option of having the outside surface of the gutter refurbished. This includes the removal of all loose paint coats the application of a sealant in any open joint and the multiple application of a very high quality white polymer coating which is not only aesthetically pleasing it is a breathable waterproof coating.
We have undertaken a large number of concrete gutter installations and can provide many references as to the quality of our product and the unobtrusive, professional manner in which we carry out the work.
