The exterior method involves excavating your walls down to the base(footings) of your home. In order quote with this method, you would need to measure the linear footage of the exterior wall. That is pretty much it. Although you need to keep in mind that additional costs may be applied depending on obstructions associated with the dig. Factors such as window wells, shrubs and trees, concrete, interlock, larger than average depths to the base of house (average depth to base of house is 5’-6’), soil composition(clay) and if the area that needs to excavated can support and has room for an excavator. If your foundation is cinderblock, it is necessary that that the entire wall is addressed because the walls are
The interior method involves breaking the concrete along the wall being treated and creating a channel for new weeping tiles. This channel is connected to proper drainage that will discharge the water away from the home. If you have a drain near the problem area, the channel can be connected along the wall and attached to the drain. In this case you would measure the problem wall and the distance to the drain for your linear footage. If there is not a drain near the wall your other option is to connect to a sump pump. This method will allow the channel to be connected to a newly installed sump pump which would expel the water out and away from your home. In this case you would measure the linear footage of the wall to where you would hypothetically place the sump pump. Remember a sump pump needs to be connected to an electrical outlet in order to operate, or a power outlet needs to be installed.
Crack injections are only possible when the foundation is poured concrete. If you have a block foundation it is not possible because the blocks are hollow. If you have a brick or fieldstone foundation there are air gaps in the concrete and mortar that injections will not completely seal. Cracks can run vertically or horizontally along the wall or floor and the price is based on a 7’-8’ length with the walls completely exposed.
