Surface waterproofing

The isolation of roofs and buildings is very necessary; This is due to the unwillingness for water to enter the house. When comparing the types of houses and buildings with each other, concrete buildings take the lead when it comes to their water resistance, but attention must be paid to cracks and cracks that can be treated, and the following are the steps for how to isolate surfaces from water:

Preparing the concrete surface before starting the waterproofing; This is done by filling cracks and expansion joints with polyurethane.
concrete surface smoothing; in order to settle it.
Clean the concrete surface well.

Choose the appropriate type of insulator, according to efficiency and cost.
Apply waterproofing by following the instructions for each type of insulation.
Applying the finishes of the chosen type of waterproofing.

Types of roof waterproofing
Types of waterproofing roofs are divided into several sections as follows: 
Cement insulation: It is an easy-to-mix cement material that is applied to the surface to be insulated.
Liquid insulation: One or two layers of liquid insulation are sprayed on the surface to be insulated.
Waterproofing using bitumen coating: It is a type of coating that acts as a protective, waterproofing layer across the surface.

Insulation using bitumen membrane: It is an insulating membrane of bitumen material that is applied in the form of blankets over the surface to be insulated when there is no consistent slope of the surface, and it is characterized by its own ability to adhere to the surface.

Insulation using polyurethane liquid: It is the application of a highly flexible polyurethane material on the surface to be isolated, but this method is considered one of the costly methods of insulation
