Membrane layer waterproofing
Our membrane layer waterproofing system is only available via the Stone Steps and Paving team. Essentially, we build a layered barrier structure beneath steps, that acts as a protective shield against water ingress. Membrane sheets for waterproofing are a favourite method among professional builders because they offer:
- Seamless protection: Since the barrier layer is continuous, there are no gaps or seams where water can seep through.
- Durability: High-quality barrier layers can last for decades, offering long-term protection against water damage.
- Aesthetics: As the waterproofing is placed beneath the steps, the appearance of the stone is not altered.
- Versatility: Suitable for various surfaces, including steps, basements and walls.
Examples:

Asphalt waterproofing
Fully waterproofing and replacing steps with our membrane layer system is an investment, it can be expensive.
For homeowners with leaking steps, our asphalt waterproofing service can be a more affordable option.
When applied to surfaces, asphalt (sticky black liquid bitumen) forms a waterproof barrier that’s tough to breach. Here’s why asphalt is a good choice:
- Robust protection: Asphalt is resistant to both water and UV rays, ensuring that the surface underneath remains unscathed.
- Flexibility: Unlike some materials that can become brittle over time, asphalt retains its flexibility, accommodating minor shifts or movements in the structure without cracking.
- Cost-effective: In the long run, asphalt proves to be a cost-effective waterproofing solution, given its longevity and minimal maintenance requirements.

Why waterproofing is important
- Structural integrity: Properly implemented waterproofing ensures that materials within your house last longer by protecting them from dampness which could lead to rotting, rusting, or decay.
- Health: Damp environments tend to promote mould growth and mildew.
- Property value: A well-maintained home with high-quality waterproofed surfaces will retain its value better than one prone to leaks and related problems.
- Return on investment: Addressing water damage can be costly. Proactive waterproofing can save property owners significant repair costs in the long run.
