Ang pag waterproofing ng roof deck slab ay para maiwasan ang pagpasok ng tubig sa loob ng bahay mula sa slab na nakakasira ng kisame at iba pang bagay sa loob ng bahay na madaling masira kapag nababasa . Upang maiwasan din ang pagtuklap ng mga pintura sa wall at para iwas short circuit din sa mga di maayos na nakabit na wirings.
Step by step kung Paano magwaterproof.
1. Linisin muna ang area kung saan iwaterproof, tanggalin ang mga buhangin at alikabok at patuyuin ang area
2. Tapalan ng grout ang mga areang lubog at may konting crack at tanggalin ang mga concrete laitance.
3. Iapply ang black primer waterproofing at patuyuin.
4. Iapply ang membrane gamit ang torch, ang membrane na ito ay ispalto na may halong maliliit na pebbles o bato. Sinusunog o iniiinit ito para lumambot para kumapit sa unang primer.
5. Lagyan ng tubig lahat ng area na may lalim na 2 inches at palipasin ng 24 oras.
Kapag walang tagas na tubig sa ilalim okay na at pasado ang waterproofing. Pwede na itong toppingan ng concrete para sa protekston nito.
The membrane of this waterproofing system is considered to be spongy and flexible. It is made of bitumen as well as some crude oil-based hydrocarbon that is to be modified with asphalt. This asphalt takes the form of either Atactic Polypropylene Plastic or APP (a plastic modified asphalt) or Styrene Butadiene Styrene or SBS (a rubber modified asphalt). This useful mixture is then properly reinforced with a layer of polyester in order to provide it with some structural integrity.
Both of these types of membranes are heat activated, and this is where a torch applied waterproofing membrane becomes more effective than other waterproofing methods. These two membranes can be joined together through properly heating the edges and eventually bonding them like the puzzle pieces. This is done in order to cover areas of different shapes and sizes.
However, like any kind of method, these two membranes also have their own set of pros and cons. The AAP is likely to be heated using a torch, making for fast installation. But it happens to be comparatively less hardwearing and flexible. Meanwhile, SBS tends to have a longer lifespan as well as better flexibility even though it may take a while for it to get heated. This is the reason why torch on roof membrane works using SBS requires more installation time.
