How much does it cost to waterproof basement walls from outside?

If you want to control excess moisture in your basement, opt for exterior walls waterproofing. The foundation walls should be exposed before waterproofing procedures. Some basements have the walls that are half-exposed so they can be waterproofed easily. Much digging may be needed for some others. However, after the exposure, the backfilling procedure should be completed. It means that all the dirt that has been dug out should be placed back. That will still provide better protection to your basement.

Bentonite Waterproofing Cost / The Cost of Waterproofing with Bentonite

Bentonite is a great construction material that is made of clay. It can expand while mixed with water molecules. It is especially related to the sodium bentonite that expands extensively and fills in the cracks and protects the walls reliably from the exterior part not allowing the cracks to form or grow wider. The material makes up a great option if your house stands on the very wet soil. However, this variant is not the best one but rather temporary because it is believed that the material cannot withstand the changes of temperatures and weather conditions.  The cost of using the betonites sheets for basement waterproofing can vary from $ ___ to $ ____ per one square foot. 

Liquid Membrane Waterproofing / Waterproofing with the Liquid Membrane

This liquid agent can be applied to your foundation’s exterior part as a more long-lasting and reliable material. It will not need any maintenance or additional application for many years.

The characteristics of this material can differ for different manufacturers so you need to look for a contractor that deals with one specific brand and has a professional certification for it. The cost of the liquid membrane installation varies between $___ and $___ per one square foot.

Sheet Membrane Waterproofing / Waterproofing with the Sheet Membrane

Such a method of waterproofing implies the installation of special sheets alongside the entire foundation, in fact, wrapping it with these sheets. However, it needs more expertise than any other method because there are seams at the points where the sheets are connected so they can become a potential source of leaking if installed improperly. Moreover, thorough preparation is needed for the walls to install such membranes, especially if the foundation is not new and the concrete is not fresh. Sometimes, several layers are installed, though one layer is enough to make this method of waterproofing easier and faster. The cost of waterproofing with the sheet membrane varies from $ ___ to $ ___ per one square foot.

The Interior Basement Waterproofing As a Good Alternative to the Exterior One

One more method of basement waterproofing is doing it from the inside. It is a very cost-effective procedure that involves the installation of a perforated pipe alongside the footing perimeter. The method implies removing the concrete from the edge of the slab and replacing it with the fresh layer. When the drain pipe is installed under the slab, it can direct the excess water downside to lower layers. The connection to a sump pump matters much in this process.

The dimpled sheet made of plastic is installed under the edge of the slab at the base of the wall. The dimpled shape allows for draining water freely into the pipes. Such an installation does not cost as much as more complicated drainage systems but it is very effective. When the soil has a low permeability, the system blocks the groundwaters from penetrating inside but there should not be an aggregate layer beneath the slab.

We can recommend this method in combination with the effective management system for soil gases that is connected to the sump pump too. The drain pipe installed alongside the perimeter of the basement should also be connected to the pump.
