Roofing waterproof construction skills

Waterproof layer is basically made on the cement base. The roof, in particular, needs both rigidity and softness for feng shui and sun exposure.

Flexible waterproof

The first layer is flexible waterproof, that is, special anti-aging waterproof coating for roof.

Mortar waterproofing

The second layer is mortar waterproofing (mortar waterproofing agent), which can protect the flexible waterproofing of the bottom layer at the same time.

Rigid-flexible structure

Roofing waterproof can't use a single waterproof material, but must be combined with rigid and flexible construction. Flexible waterproof has good stretch, and a little settlement or deformation will not damage the waterproof layer. Rigid waterproofing (mortar waterproofing agent) can play a protective role while waterproofing, and the waterproof layer is not easy to be damaged.
