Specialist Protection for Below-Ground Structures

Effective waterproofing for below-ground structures is essential to prevent moisture ingress, structural damage, and long-term degradation. Specialist waterproofing products, such as waterproof paints, coatings, and dampproof membranes, are designed to protect concrete, brick, and blockwork from the harmful effects of water and dampness. These products are integral in safeguarding foundations, basements, retaining walls, and other underground constructions, ensuring their longevity and performance over time.

 

Solutions for Varied Applications

Waterproofing systems for below-ground structures offer solutions that cater to both floors and walls. Products from leading brands like Fosroc, Sika, Mapei, and Resimac deliver superior performance, particularly in challenging underground environments. These systems provide protection not only from water but also from ground gases and volatile organic compounds (VOCs), which can be harmful to building integrity. Additionally, they are suitable for complex details such as pipe entries, covings, and structural joints, ensuring a complete, robust seal across the entire structure.

 

Comprehensive Protection for Underground Works

Underground works require more than standard waterproofing. The unique conditions found below ground, such as increased moisture and pressure, necessitate products that are engineered to withstand these environments. From basements to underground storage areas and tunnels, waterproof coatings and membranes play a critical role in maintaining structural soundness. Many of these systems incorporate dampproof technology, adding another layer of protection against potential damage caused by moisture or gas infiltration.

 

Ground Gas and VOC Protection

In addition to water resistance, specialist waterproofing products for below-ground structures also offer protection against ground gases like methane and radon, as well as VOCs. These hazards can compromise air quality and pose significant risks to building occupants if left untreated. By incorporating gas barriers and VOC-resistant membranes, these systems ensure comprehensive protection for underground environments.
