Job Stories From Bellevue, WA
Pooling Water in Bellevue, WA

Barry W. had a problem with his front walkway in Bellevue, WA, as it was pooling water right before the concrete steps due to settlement. He was worried that this could lead to a slipping risk or the water flowing into his foundation, so he contacted TerraFirma for help. 

Tulane Seville, the Sales Manager, met with Barry and assessed the property. He found that not only was the walkway settled, but the front steps had also cracked and settled. To fix this issue, Tulane recommended TerraFirma's Concrete Leveling Solutions, which involved using polyurethane foam and Nexus Pro. He then passed on this information to Robert Marciniak and his crew to come up with a plan. 

The TerraFirma crew quickly got to work and within a day, they had repaired and stabilized Barry's walkway and front steps. As a result, the pool of water and the potential slipping hazard were eliminated.
