Waterproofing Basement Cost

The process of waterproofing is rather complicated. It consists of many different stages, such as making an outline, getting the place ready for repairs, foundation sealing, wall waterproofing with the help of cement, drain or sump pump installation, driving the downspout flow away from the foundation walls, repairing cracks in the walls with epoxy injections, and some others.

The approximate cost of waterproofing basement is $0,000 to $0,000. The average amount can also be counted on the basis of spent materials and labor that may be estimated as between $0 and $0 per square foot. If the work does not need any excavation, for example, interior waterproofing, the cost may be lower – around $000 to $0,000. If you  need more extended repairs of severe foundation issues and drainage system installation, you will pay a bit more – $00,000 and above.

Cost of Waterproofing Basement from Outside

To repair and waterproof the basement from the outside is a very popular and widely used method. External waterproofing is the best technology to ensure the long lifespan for your basement walls. It is strongly recommended to waterproof the foundation from the outside to prevent water penetration into the walls and floor of the basement.

If the foundation is made of cinder blocks of poured concrete, waterproofing is a must. These thick materials can absorb water easily and cause problems with excess humidity in a while. If you live in the area with a high water table, good-quality waterproofing can help protect the basement from heavy water flows. The main aim of waterproofing is protecting the house from heavy rainfalls, runoffs, and floods.

Using a Special Membrane for Waterproofing of a Foundation

When you decide to install the membrane, consider the necessity to excavate the ground to add special drainage panels. They will block the excess water from penetrating. It is recommended to install a liquid panel. It does not have seams so there is nothing in it that can support leaking. The cost of such a panel is $0.00 to $0.00 per square foot per coat if you opt for the membrane made of crystalline or elastomeric materials. Normally, you will have to apply 2 or 3 coats.

You can also choose a sheet membrane. It is great for waterproofing when you wrap it around the foundation footing made of concrete or over the walls. It can also be applied to the drain system alongside its perimeter. The installation should be done close to the footing and the cost of it varies from $0.00 to $0.00 per square foot.

Using bentonite clay can approximately cost $0.00 per square foot including the cost of labor for setting one layer of the material.

The price involves the size of the house measured alongside the perimeter and the amount of excavation needed for that.

The price depends on the difficulty of access to the foundation walls and the depth of excavation. Normally a contractor that deals with excavation work can charge the minimum of $0,000 or more.

How to Estimate the Cost of Your Basement Waterproofing

So, what do you need to consider while estimating the real cost of your basement waterproofing? There are several factors to be taken into account. The final cost can depend on the actual size of the basement, on the issue that has made you waterproof the space, and the quantity of materials and labor to do all the job.

How to Detect the Source of the Issue

The immediate examination is needed to figure out where the excess moisture is coming from.

The source of the moisture in the basement can be the following:

  • Gutters and downspouts have been installed incorrectly or haven’t been installed at all.
  • The laundry work inside the basement is immense.
  • Water pipes are leaking.
  • The foundation has bad cracks in its walls.
  • The slopes around the house are graded improperly or not graded at all.
  • The excess ground water because of severe rainfalls and soil saturation can penetrate the basement.
  • The window wells are designed incorrectly.

If you know how to determine where the source of moisture is, you have done half of the job on estimating the total cost of repairs.
