The most effective and durable waterproofing ways for toilets - Can do it yourself.

Toilets are the wettest place in every house and absorbing toilets is nothing too strange for Vietnamese people. Seemingly simple, but there are countless toilets to be leaked. There are two types of toilet waterproofing which are waterproofing from the time of construction and handling of leakagesduring use.

1. There are two causes of toilet leakages that are:

- Not waterproof from the beginning.
- Waterproofing from the beginning but improperly waterproofing.
* First, to waterproof the toilet, we need to imagine the structure of a toilet with a common design consisting of 5 overlapping layers from top to bottom:
+ The top layer of ceramic tiles.
+ Weak mortar layer for tiling.
+ Buffer sand layer.
+ WATERPROOF FILTER CLASS.
+ The bottom layer is concrete floor.
+ The neck pierces the floor.

The waterproofing membrane is most important as a large raincoat covers all the above layers so that water does not seep into the concrete floor causing leak. So thoroughly waterproof the toilet is to use quality waterproof membrane, and waterproof pipe neck properly.

* There are some toilet waterproofing mistakes that some families encounter below. These ways you should not do because the life is very low due to not solving the problem of waterproofing at the root:
+ Using a glue to flow water directly into the water collecting funnel. This is only a few months because adhesives are very good adhesion, but after a few months of use of water will easily pass through and the toilet will be re-absorbed.
+ Waterproofing directly onto layers of tiles without chipping out. This is only a short time because with this method the weakest position is the pipes neck position. At this time, water will easily slip through the neck of the tube and crept onto the old floor. We had to repair a lot of these toilets.

+ Reverse waterproofing by pumping expansion glue below the floor. Waterproofing expansion glue is only to disconnect the water to ensure a dry construction surface for troubleshooting with other specialized materials (The cost is quite high). Usually the leaks problem of underground works due to groundwater pressure is required to use swell glue to disconnect the water to be able to continue construction. The life expectancy of the gelatinous sealant is only about 1 year, the glue is rotten and the situation of wetting will be worse when the glue is broken. So this way does not guarantee long-term effectiveness.

+ There are many products of waterproofing membrane materials. For toilets this is a wet area, when the construction is completed and put into use, the waterproofing membrane will be filled with water so you should use two-component waterproof membranes Polymer + Cement base (Original the more soaked the cement is in water, the longer it will last) .This type of membrane is applied as a sweeping or spraying type, so there are no joints or sheets such as hot, cold-rolled sheets. For the type of spreader, it is necessary to have a high level of skills because the infiltration problem is rarely on the surface of the sheet, but after a while, the seepage situation often appears in 4 angular positions or joints. We recommend that all toilets use Polymer + cement-based waterproof membrane. Some of you use PU-based waterproofing material (Polyurethane) when the construction is very beautiful, waterproof testing but going into re-use because the life span of PU-based waterproofing membrane when immersed in water is very poor, This type of membrane should not be used for toilets.

2. How to waterproof the toilet for toilets in use.

To waterproof the toilet, we need to deal with the root problem that is waterproofing on the concrete floor.
B1. Perforated ceramic tile floor, clean flat to the concrete floor layer and chisel the drainage pipes, opaque water supply 5 cm wide and 10 cm deep to waterproof the pipe neck. Perforated rows of baseboards for waterproofing membrane up to 20 cm above the floor.
B2. Grinding surface flat, patching holes, angled positions rounded round plaster. This step is to create a smooth floor and wall surface before executing the waterproofing membrane.
B3. This step is very important. Conducting waterproofing of pipe necks. For collars, waterproof by wrapping expanded rubber, then pouring mortar without shrinkage. Conventional, non-shrink, non-shrink grout you can use SIKA GROUT 214-11. When the mortar neck is dry, apply SIKA FLEXCONSTRUCTION elastic sealant to seal it.
B4. Re-check surface before executing waterproofing membrane. Ensure the surface is flat, solid, free of impurities and water.
B5. Conducting the construction of waterproofing membranes. Note the corner of the foot of the wall, you reinforce more glass mesh or polyester mesh to avoid cracking, broken waterproofing membrane in this area, during the construction process, you need to measure the thickness continuously to avoid the construction of the film. Waterproofing is too thin. Construction waterproof membrane for the toilet you need to use a brush to sweep waterproof membrane to ensure the meticulousness and thickness of the waterproofing membrane. The angular part is done before the floor after. Reference materials: SIKA TOPSEAL 107, SIKA TOPSEAL 109.
B6. After the waterproofing membrane has dried, carry out maintenance and pour water into the water test within 48 hours.
B7. Apply the top layers of protective mortar to the waterproofing membrane, screed, and tiling.

3. How to waterproof the toilet for new houses.
You proceed to do steps from B2 to B7 above are the steps for waterproofing construction of new toilets.
