At Decking Waterproofing, we specialise in safeguarding decks from water infiltration, environmental exposure, and damage. Our customised solutions ensure that decking remains resilient, safe, and resistant to deterioration, significantly extending its service life.

We work on residential, commercial, and industrial decking, using premium materials that comply with industry standards, in Westbury and throughout the UK. Our efficient processes reduce disruption, keeping decking areas well-protected and structurally sound.

What Are the Benefits of Decking Waterproofing?

Decking waterproofing enhances durability by protecting against water ingress, chemical exposure, and temperature variations, ensuring lasting performance. It improves resistance to moisture damage, preserving the underlying structure and reducing the risk of decay and surface wear.

By preventing surface degradation such as rotting, warping, and cracking, it boosts safety for users and maintains the aesthetic appeal of the decking. The investment also cuts down on maintenance costs, offering long-term savings and meeting relevant compliance standards.

How Much Does Decking Waterproofing Cost?

The cost of decking waterproofing varies based on the method: bituminous membranes cost between £15 and £35 per m², liquid-applied membranes range from £20 to £45 per m², while composite decking with waterproofing layers costs £40 to £90 per m².

Additional costs may include surface cleaning, sealing joints, and preparing the substrate. Though the upfront investment may seem substantial, waterproofing extends the decking’s lifespan, reducing future repair expenses.

What Are the Most Common Methods of Decking Waterproofing?

Decking waterproofing methods are selected based on material, usage, and environmental factors, including:

• Bituminous membranes – Flexible asphalt layers applied to decking surfaces, suitable for high-traffic areas, cost-effective but prone to cracking with structural movement.
• Liquid-applied membranes – Polymer-based coatings sprayed or rolled onto the decking, offering adaptability for complex shapes but requiring thorough surface preparation.
• Sheet membranes – Prefabricated sheets bonded with adhesive or heat, providing chemical resistance while necessitating accurate installation.
• Spray-applied polyurea coatings – Rapid-curing, durable coatings that bridge cracks and resist chemicals, requiring specialised application equipment.

How Is Decking Waterproofing Installed?

The decking waterproofing installation process starts with a thorough inspection to assess damage and potential water ingress points. The surface is then prepared by clearing debris, cleaning the area, and addressing any cracks.

The selected waterproofing method (bituminous, liquid-applied, or sheet membrane) is applied, followed by a protective finish to increase durability. Integrated drainage solutions help manage water runoff. Final quality checks are performed to verify waterproof integrity and adhesion.

How Long Does Decking Waterproofing Last?

The longevity of decking waterproofing depends on the chosen method: bituminous membranes typically last 8-12 years, liquid-applied membranes 12-18 years, polyurea coatings over 20 years, and composite decking overlays 15-25 years.

Regular maintenance, such as cleaning, inspecting drainage, and repairing minor damage, helps maximise the lifespan of the waterproofing system.
