A house or building is meant to withstand forces of nature; wind, sun, and rainstorm. Rooftop deck and roof are another vital part because it helps protect house from forces of nature. After a while, there might be crack and leak problems, so that choosing the right product for waterproofing the house is very important, the products that address other factors such as vibration or movement including deep stain. Mr. Crocodile would like to offer suggestion in 2 parts as followed.
Roof
Roof is the area with the most leaks, and certainly mostly lead to damaging a house as well. These require correct way to repair. Roof leak problems tend to happen in these points.
1. Fixing Equipment
Bolts, screws, rubber gaskets, zinc caps degrade.
2. Roof Tiles
Tiles have chips or cracks, wrong roof pitch.
3. The area that roof tiles meet wall, or roof flashing.
Roof flashing is too short or too high from tile level.
4. Roof Ridge Cap
Roof ridge cap cracks. Cement joint does not seal neatly to tiles.
5. Leaks in Roof Valley
This is caused by tiling too close to each other.
6. Leak because of Roof Deflection
The construction work quality is not up to standard.
Those aforementioned “roof” problem could be repaired with these products as followed.
1. Crocodile Roof Shield (Waterproof Acrylic Product)
The product is a top quality waterproof acrylic that can withstand water longer than other generic acrylic with over 500% flexibility.

It is suitable for waterproofing roof, concrete, roof tiles, zinc, and rooftop deck with pitch or sloped well already.
2 Crocodile Poly-U Seal (Polyurethane Joint Sealant)
The product is for sealing joint, seam, crack, concrete area subject to movement or vibration. It can adhere to various surfaces, and can fix groove or crack with a width of 3 – 12 mm and 5 – 10 mm in depth.
3. Crocodile Tape Seal (Butyl Tape Aluminum Woven Foil)
The product is high quality multipurposed butyl seal tape with high cohesive bond and shear resistance, for sealing roof joints and seams, roof gutter, roof ridge cap, to prevent leakage.
Rooftop Deck
Rooftop deck is another area in the house that often leak, and not only from rain water, but also tap water if daily life such as cleaning activity. This water can leak in and damage lower storey. These must be correctly repaired. The main causes of rooftop leak include:
1. Waterproofing coating degrades
2. Constantly changing temperature expands and shrinks concrete and in turn cause cracks.
3. Slop or pitch is not sufficient (less than 1 to 200), leading to puddle.
4. Water drainage pipe is smaller than 3 inches, which is smaller than standard. Then it fails to drain properly, leading to puddle.
5. The concrete topping is too thin, and easily cracked and chipped.
After suitably completing structure and concrete pouring as well as sloping, the final step of the construction is waterproofing the concrete surface, Mr. Crocodile would like to suggest these chemical products as followed.
