Lowcountry Foundation Repair Case Studies: Erosion Under Hotel Parking Deck in Savannah, GA is Fixed!

Friday, November 16th, 2018 by Michael Connolly

Challenge

The Savannah River had slowly been eroding the soil under the Savannah Marriott Riverfront Hotel parking deck. The void was measured with a snake camera. The area was approximately 15 feet wide and 20 feet long. The parking deck was sagging 2 inches from the original grade.


Management of the Savannah Marriott Riverfront Hotel wanted to stabilize the foundation and prevent further issues. Lowcountry Basement Systems was called to inspect the settlement and fix the problem.

Solution

After the inspection, it was recommended to fill the voids under the parking deck with PolyLevel. PolyLevel is a two-part polyurethane foam that can be injected beneath settled concrete. Management approved the project and Lowcountry Basement Systems went to work.

Small holes the size of dimes were drilled through the parking deck concrete to allow PolyLevel to be injected. As PolyLevel was injected the foam expanded. The two components mixed, and created enough expansive power to fill the void and lift the parking deck.

PolyLevel is environmentally-friendly. The material does not react with soil and does not release harmful chemicals. PolyLevel does not impose added weight on unstable soil, but can still support a substantial load. PolyLevel is also waterproof and will not wash away once it has cured.

The job took one day for the Lowcountry Basement Systems’ team to complete. Management was happy.

PolyLevel: 40 square feet long x 31 square feet wide x 6 square feet deep
