Waterproofing Elevator Shafts
Elevator shafts may be exposed to moisture, and even leakage problems in time due to weak, or deteriorated insulation, or cracking of the concrete.
Waterproofing elevator shafts from outside is mostly impossible. So the problem can be perfectly solved by applying Permo Chim Crystal from inside, which is a waterproofing material resistant to negative water pressure.
The surface to be treated must be clean and solid, and free from water repellent materials such as grease, rust, cement foam, paint residues, curing materials, release agent and silicon.
Cracks found in static, or non-moving parts must be enlarged, moistured and repaired with plaster and repair mortar containing Emulzer Latex.
Any dynamic, or moving cracks must be waterproofed with Emulzer Anchorage Paste. (See Eliminating Water Leakage At Floor/Wall Intersections In Basements)
The areas prone to cracking such as pointed tips or horizontal/vertical intersections must be beveled.
Any pressured water leakage from the wall must be blocked by Speed-X Powder (Figure 1-2) (See Blocking Pressured Water).
And then the surface must be saturated with plenty of water and kept damp all through the application.
Permo Chim Crystal is poured into a clean container, and mixed with 10 liters of water for brushing or 7 liters of water for trowelling until a homogenous mixture is obtained (for approximately 3 minutes with a low speed mixer).
You should add water to Permo Chim Crystal; never vice versa. Water must be added gradually, not all at once.
