Waterproofing--By Trowel--Exterior

What Does GL Code 99953 Cover?

ISO GL class code 99953 specifically covers contractors specializing in exterior waterproofing applications performed by trowel. This classification applies to businesses that apply waterproofing materials to the exterior surfaces of structures, primarily using trowel-based methods, to prevent water intrusion and damage. It encompasses operations focused on protecting building exteriors from moisture.

Who Uses This Class Code?

Businesses that fall under this code include specialized exterior waterproofing contractors, masonry restoration companies performing waterproofing, and building envelope specialists. These are typically firms that focus on applying sealants, membranes, and coatings to foundations, walls, and other exterior elements of commercial and residential properties.

Common GL Claims for This Class

Common General Liability claims for exterior waterproofing contractors include property damage due to water intrusion from failed waterproofing applications, leading to mold growth or structural damage inside the building. Other claims may involve damage to adjacent property during the application process or allegations of faulty workmanship resulting in leaks.

Coverage Tips for Code 99953

• Ensure your General Liability policy includes 'Completed Operations' coverage, as many waterproofing failures and subsequent claims may arise after the project is finished and accepted by the client.
• Verify that your policy does not contain exclusions for 'EIFS' (Exterior Insulation and Finish Systems) or 'synthetic stucco' if your work involves these materials, as these are common areas for coverage disputes.
• Maintain meticulous records of all materials used, application methods, and project specifications, as detailed documentation is crucial for defending against potential construction defect claims.
• For Florida contractors, be aware of specific building codes and licensing requirements related to waterproofing and moisture intrusion prevention, as non-compliance can lead to significant liability and coverage issues.
