To ensure proactive waterproofing for the basement is highly effective during the anti-seepage construction process, you need to pay attention to the following important things:

- For wall and foundation concrete, it is necessary to compact thoroughly, avoiding tangles and over-compaction. It is necessary to compact again and again to ensure that the concrete is compacted firmly. For wall concrete, you should only construct each layer with a height of about 50 cm, gradually rolling up. Each location needs to be placed with a waterstop to prevent leakage at the concrete stop location. Be careful during the pouring process not to let too much aggregate fall to the bottom of the poured layer, which can easily cause the concrete to become porous, which will cause future leaks.

- The lining or mortar coating layer needs to be applied continuously to avoid interrupted construction. If it is not possible to do it continuously, it is necessary to pay careful attention to handling the hybrid layer between plastering sessions.

- The waterproofing material layer needs to ensure the thickness according to the design, without defects to ensure effective protection of the project. This is an important material layer that determines the waterproofing effectiveness of the project. Refer to Sika waterproofing additives to choose suitable materials for this layer

- The rubber paper layer is spread on top after the waterproof material layer has dried. Be careful during construction not to damage the waterproofing material underneath.

- The clay layer constructed outside the retaining wall needs to be layered according to the height of the wall. It is necessary to ensure sturdiness to prevent water from seeping into streams.

- The protective soil layer on the outside can use compacted sandy soil and do not use construction waste.

The same goes for waterproofing walls. Water that wants to soak inside cannot flow because there is a clay layer so it can only soak in moisture. Then encountering the waterproofing material layer, cement mortar layer and compacted concrete layer, the possibility of getting inside is very low.

From theoretical and experimental basis, it shows that proactive waterproofing of the basement has maximized the waterproofing ability. With many layers capable of preventing water, errors in each layer will hardly affect the remaining waterproofing layers. This is an important factor that helps minimize water seepage into the basement.
