Your basement is prone to “water attacks” with time. This can make up very big damages to the home, hence, the need for basement waterproofing. Waterproofing requires the introduction of materials that help prevent water from permeating the whole essence of the basement.
In each case of waterproofing, the processes all start with a consultation. Here are some of the processes underlying these kinds of basement waterproofing.
External Basement Waterproofing
External basement waterproofing has been highlighted as the best method for protecting the basement against water. The processes involved here are quite more elaborate and labour-intensive than the internal basement waterproofing. After consultancy of a plumbing agency, they analyze the problem and work begins based on recommendation.
Processes involved in external basement waterproofing include:
This can be otherwise called digging around. It involves striking through the earth until the foundation walls are visible. If the only problems involved are with the weeping tiles and or French drain, then full excavation will not be necessary. Excavation is typically between 4 to 8 feet.
- Fix Cracks and Clean
If the foundation has weeping tiles, they are detached from the foundation walls and cleaned. There usually is a possibility for cracks permitting water into the foundation. This process finds such cracks and fixes them with hydraulic cement which is a coat that expands. Hydraulic cement reduces the possibility of cracks even in the future.
- Application of Membrane
This thoroughly shields the foundation from water. It involves the use of polyurethane materials. The use of quality products here is essential. Elastomeric membranes, for example, are great waterproofs. They can move to inhibit cracks when they eventually occur.
- Installation of Drainage Mat
You will need to install a drainage membrane that has moulded dimple sheets. It is usually sized the same depth as the foundation. It acts to inhibit lateral pressure for the foundation and serves as a drainage membrane.
After these processes, the French drain or weeping tile is installed at the bottom of the footing weeping underneath the basement floor. Then, backfilling is done with the native soil excavated from the foundation. And the home is secure.
Your basement is prone to “water attacks” with time. This can make up very big damages to the home, hence, the need for basement waterproofing.
Internal Basement Waterproofing
This is inferior to the external basement waterproofing. It is done in cases where the foundation cannot be accessed directly or where excavation is optimal. It begins with consultancy and identification of the problem areas.
The processes involved include;
- Breaking the floor area involved, about 7-10 inches away from the walls of the foundation.
- Installation of the weeping tile (3 inch and perforated) is done after the concretes are removed.
- The weeping tile is connected to a floor drain or pump
- Dimpled membrane drainage sheet and ¾ inch gravel are added to the weeping tile.
- Concrete is used at the last stage on the exposed part back to the ground level.
External and internal basement waterproofing are both essential based on situations to counter water permeation. The external method is preferred because it attacks the problem from the real source. Contact your local plumbing company to get a perfect response on your basement waterproofing needs.
