Waterproofing remains one of the most essential components in the longevity and performance of commercial infrastructure. In 2025, evolving building regulations, climate resilience and asset protection are driving demand for smarter, more sustainable waterproofing systems. At Composites Construction UK, we’re proud to deliver advanced waterproofing solutions that protect infrastructure investments across numerous sectors, from buildings and bridges to tunnels and car parks.
Here’s a look at the top waterproofing systems making an impact in 2025.
Liquid-applied membranes
Still a leading choice for commercial infrastructure, liquid-applied waterproofing membranes offer seamless, joint-free protection. Thanks to improved formulations, today’s systems cure faster and adhere better to complex geometries and substrates. Elastomeric coatings are particularly effective on roofs, podiums and ramps, forming flexible barriers that resist cracking, even in extreme temperatures.
Many of the latest products also meet higher sustainability standards, with low-VOC options and enhanced durability reducing maintenance needs and lifecycle costs.
Bituminous membrane systems
Tried and tested, bituminous waterproofing remains popular in below-ground and substructure applications. Modern developments in polymer-modified bitumen have increased flexibility and UV resistance, helping to extend the life of buried structures and retaining walls. Self-adhesive bitumen sheets have also grown in popularity for their ease of installation, reduced labour costs, and consistent performance on complex projects.
Spray-applied polyurea coatings
Fast-curing polyurea systems are gaining traction for commercial sites that require minimal downtime. These systems are ideal for high-traffic areas like car parks, loading bays and industrial flooring. When applied by trained professionals such as the engineers at CCUK, spray-applied polyurea forms an exceptionally tough, chemical-resistant membrane within seconds, safeguarding structures against abrasion, water ingress and thermal movement.
Cementitious waterproofing
Advancements in polymer-enhanced cementitious coatings have made these systems more flexible and versatile than ever. Often used on concrete substrates, they’re especially suited to water-retaining structures such as reservoirs, treatment plants and basements. Easy to apply and compatible with damp surfaces, these systems offer excellent resistance to positive and negative water pressure, making them a reliable choice for below-ground waterproofing.
Carbon fibre integration for structural waterproofing
A standout development in 2025 is the use of carbon fibre-reinforced polymer (CFRP) systems that combine structural strengthening with waterproofing capabilities. CCUK is at the forefront of integrating carbon fibre wraps and laminates into waterproofing designs, particularly in critical infrastructure such as bridges, culverts and marine environments. This dual-function approach not only prevents water ingress but also enhances structural performance and extends service life.
Choosing the right system for your project
No two commercial projects are the same. Factors like substrate type, load requirements, site conditions and lifespan expectations all play a role in choosing the right waterproofing approach. That’s why CCUK offers tailored waterproofing solutions backed by expert consultation, on-site support and long-term warranties.
Whether you need protection for a new build property or a retrofit for an ageing asset, our team can design a solution that meets performance standards whilst minimising disruption and cost.
