What is reverse waterproofing for buildings?

Reverse waterproofing for construction works is a solution to waterproofing the inside of the building (the side that is not in direct contact with the source of water seepage). In other words, reverse waterproofing is the way that the waterproofing contractor is in the opposite direction to the source of the seepage. This option helps the waterproof surface to not be stagnant water and prevents capillary phenomenon inside the structure of the building.

When the protective layer, waterproofing outside the building (forward waterproofing) cannot prevent water from seeping into the wall, surface... then reverse waterproofing will be the best solution to reduce water pressure, avoid peeling walls, The building deteriorated rapidly due to water infiltration.

Causes of reverse seepage

The phenomenon of reverse water seepage at construction sites mainly originates from a number of basic causes as follows:

  • Due to water or moisture penetrating through the capillaries in concrete structures, brick wall structures.
  • Due to heavy rain, rainwater penetrates from the outer wall through the inner wall.
  • Due to the high humidity environment, water condensation on the wall for a long time causes mold, leakage and water infiltration.
  • The process of building the wall foundation does not ensure the technical process, not using enough cement mortar when building, leading to a large gap between bricks, creating conditions for water to penetrate quickly and deeply into the wall.

Cases where it is necessary to take measures for reverse waterproofing for specific works such as:

  • Permeation of walls due to water entering between 2 adjacent houses
  • Swimming pools, underground tanks, underground floors, gardens are at risk of seepage due to external groundwater sources
  • The wall is cracked or is too old and there is a phenomenon of water seepage from the outside to the inside

What type of material is used for reverse waterproofing?

  • Clean cracks, remove defective concrete
  • Remove obstacles and clean the work surface area to perform.

Step 3: Construction of reverse waterproofing

  • Fix drain pipes with mortar
  • Start applying a reverse waterproofing layer to the surface
  • After 3 hours enough for the waterproofing layer to dry, continue to use Sika waterproofing chemicals by covering the surface with 2-3 layers of Sika (This step is fast or slow depending on the drying speed of each layer of Sika. different waiting times).
