Waterproofing and Dampproofing Basements from Inside (Concrete or Plastered Surfaces)
Basements may be exposed to moisture, and even leakage problems in time due to weak, or deteriorated insulation, or cracking of the concrete.
Although it is healthier to insulate from inside, it may not always be possible due to factors such as adjacent buildings or high excavation costs. So the problem can be perfectly solved by applying Permo Chim Crystal from interior surfaces, 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 motionless 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 filleted.
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.
