Analysis Finds Installation Issues in Lincoln Memorial Reflecting Pool Renovation

The Lincoln Memorial’s Reflecting Pool experienced peeling in at least seven areas along its seams. A Washington Post analysis, supported by expert interviews, suggests that improper installation is the main cause. President Donald Trump claimed vandalism was responsible for the damages, which appeared shortly after a $14 million renovation completed in early June.

On his Truth Social platform, Trump described the incidents as acts of vandalism. Interior Secretary Doug Burgum echoed this sentiment on Fox News, attributing the damage to deliberate actions by individuals looking to destroy a monument. However, a visit by reporters and a visual analysis revealed that the peeling occurred at the seams where different sections were painted.

Experts in waterproofing reviewed the findings and pointed to a likely error in the application process. Seams are prone to failure if not handled carefully. While a definitive cause without onsite work and lab testing is impossible, improper application timing might be responsible.

The application process involved two products: Rhino 406 and Pipeliner 5000, manufactured by Rhino Linings. The materials were applied in stages during May. Issues arose at the seams where the coating failed, suggesting adhesion problems. Technical documents specify that Pipeliner 5000 must adhere within a certain timeframe, yet delays occurred at multiple spots.

Photos and satellite imagery confirmed a more than 24-hour gap between the application of adjacent sections, potentially undermining the coating’s effectiveness. At another spot, where both the Pipeliner 5000 and the base primer peeled, expansion joints in concrete were noted as additional stress points.

The Post shared their findings with the White House and the Interior Department, who disputed claims of improper application. Officials insisted the installation process followed guideline standards and attributed damages to vandalism. Yet, no evidence was provided to support these assertions.

Atlantic Industrial Coatings and subcontractor Mid-America Industrial Coatings, involved in the renovation, did not respond to inquiries about the alleged vandalism and the coating failures. Both companies previously worked with Rhino materials. Additionally, Rhino Linings stated the coating separation did not affect the underlying waterproofing membrane.

The renovation followed a no-bid contract awarded to Atlantic Industrial Coatings in April, given the complexity and time constraints related to the project. Past efforts to address leaks and algae problems included a significant floor support system renovation in 2012. Sika, a company involved in previous work, declined participation in the latest renovation due to project feasibility concerns.

Doug Burgum has since confirmed that repair efforts are underway, potentially costing tens of thousands of dollars. The same contractor, Atlantic Industrial Coatings, will handle the repairs, despite the recent challenges faced in the initial installation.
