How can you prevent groundwater infiltration in underground structures?

1 Assess the site conditions

Before you start any construction project involving underground structures, you need to conduct a thorough site investigation to assess the soil conditions, water table levels, and hydrostatic pressure. These factors will determine the type and extent of groundwater infiltration you may face and the appropriate design and construction methods to prevent it. You can use various tools and methods to collect and analyze the site data, such as boreholes, piezometers, permeability tests, geophysical surveys, and hydrological models.

3 Apply a waterproofing system

A waterproofing system is another key component to prevent groundwater infiltration by creating a barrier between your underground structures and the water source. There are different types of waterproofing systems available, such as membranes, coatings, sealants, admixtures, and injections. Each type has its own advantages and disadvantages, depending on the site conditions, the type of structure, and the budget. You need to select and apply the most suitable waterproofing system for your project, following the manufacturer's instructions and the industry standards.

5 Follow the codes and regulations

To prevent groundwater infiltration in underground structures, you also need to follow the relevant codes and regulations that apply to your project. These codes and regulations may vary depending on the location, the type of structure, and the purpose of use. They may specify the minimum requirements and standards for site investigation, drainage design, waterproofing application, structural design, construction methods, and inspection and testing. You need to comply with these codes and regulations to ensure the safety, quality, and legality of your project.
