Foundation Repair – The 8 Step Approach To Waterproofing

1 – Foundation Excavation Starts the Waterproofing Process

A combination of machine and hand digging allows access to your foundation to begin the waterproofing process without any risk of damage to the foundation. Your contractor must excavate all the way to the footing to examine the existing drainage and the condition of the foundation wall and footing. Once the excavation is complete, power-wash the foundation to remove all loose materials and examine the foundation for damage.

2 – Repair

Depending on the condition of the foundation, this step may vary. If there is any damage to the foundation it will have to be repaired.

3 – Add Footing Bevel to the Foundation for Better Waterproofing

We then apply a bevel of concrete at the joint where the foundation meets the footing. This helps to seal up one of the most vulnerable parts of the foundation. This seam is often the source of water getting into basements.

4 – Install Blueskin Waterproof Membrane on the foundation wall.

Blueskin is a rubberized asphalt membrane laminated to a Polyethylene film. This combination provides a durable, waterproof barrier that is tough and flexible and can stretch to continue providing protection even if new cracks develop after the membrane has been applied.

A primer is rolled on and then the Blueskin applied over the primer. The priming layer provides the perfect surface for the Blueskin to adhere to and provides a small amount of damp-proofing on its own. Remember, the Blueskin is providing waterproofing not just damp-proofing.

5 – Add a Protective Platon Membrane

After the Blueskin, the foundation should be wrapped in Platon Membrane which provides the first defense against water and provides physical protection to the Blueskin membrane. Platon Membrane is a tough, dimpled, 24-mil high-density polyethylene wrap that seals out water. The dimples provide an air gap behind the Platon so that any water that might get behind the membrane can drain down and won’t be trapped between the Platon and the Blueskin.

6 – Install New Drainage Tile

The next 2 steps in ensuring a dry basement are perhaps the most important: proper drainage and grading. It essential that when water flows down the Blueskin and Platon membranes that there is a system in place to carry the water away from the foundation. The age of your home will often determine the drainage solution that is available for your foundation. You may be connected to the city storm drain, a French drain on your property or to a sump pit in your basement. However, regardless of drainage solution, your contractor shouldl lay a new bed of gravel at the footing, install new window wells and drains if required, install new Drainage tile and connect it to the drainage. The Drainage tile has a “sock” that covers it to help filter out silt so that the pipe does not clog over time. Finally the new drainage tile is covered with clear gravel so that water can drain easily through it.

7 – Proper Grading in the Important Final Waterproofing Step

After the waterproofing steps are completed, the excavation around the foundation is backfilled and graded so that there is sufficient slope around the house to encourage water to run away from the foundation. Keeping water from getting to the foundation is the first line of defense in keeping a dry basement.

Compaction should be performed on a regular basis while backfilling to prevent the earth from sinking over time around the foundation.
