Groundwater has a destructive effect on residential buildings, and basement floors, basements and other premises located below ground level should be considered particularly vulnerable places. Today we will talk about why waterproofing from groundwater is needed, explain what negative (negative) water pressure is and what substances are optimally used to protect the basement.
Why is waterproofing from groundwater necessary?
First of all, it is worth explaining that groundwater has a negative pressure on the construction. In simple terms, water and steam tear off the waterproofing layer from the foundation, thus violating the integrity of the structure and negatively affecting the masonry.
If the problem is not solved in time, a small wet spot in the basement will eventually turn into a real breach, and groundwater can flood the room located below ground level. This is the main reason why it is necessary to apply waterproofing in basements, basement floors, etc. The modern construction market offers several solutions to the issue, one of the most effective is deservedly considered penetrating waterproofing.
How can penetrating waterproofing be used for a basement?
In order to reliably isolate basements from groundwater, Teknomer 200 Crystallized penetrating insulation is used. The elastic mixture consists of two components: an emulsion polymer in liquid form and a special powder consisting of cement and additives to increase water resistance.
The substance penetrates into the pores of the treated material, giving the surface resistance to negative and positive groundwater pressure. Protects against leaks and ingress of surface water masses. It has a water resistance of 4 bar at negative and 7 bar at positive pressure. It is applied at a temperature of 5 °C - 35 °C, and put into operation 7 days after application.
The advantages of penetrating polymer cement waterproofing are as follows:
high adhesion – from 1.00 N/mm2- resistance to positive/negative pressure
- resistance to freezing and thawing, thermal stability in the range - 40 ° C - 80 ° C
- preventing the carbonation process of concrete structures
- possibilities of application on vertical and horizontal planes, outside and inside, on concrete, brick, screed and plaster
- ease of application with a brush, roller or spray.
