Guarantee & Protection

Built To Last. Guaranteed To Protect.

Discover our long-term waterproofing guarantees and protection promise — designed to give you complete peace of mind, from project completion to decades of performance.

Our Guarantee & Protection Promise

Confidence Built on Quality

Every project completed by ARTI Waterproofing is backed by our unwavering commitment to quality, durability, and long-term protection.
With more than 25 years of expertise in structural waterproofing, we don’t just deliver systems — we deliver peace of mind.

Our installations and designs are carried out in full compliance with BS 8102:2022, the benchmark British Standard for below-ground waterproofing, and every material we use is sourced from trusted manufacturers.

Our 10-Year Workmanship Guarantee

Our guarantee covers all workmanship and installation carried out directly by ARTI Waterproofing.

This means:

  • Every project is installed by our qualified in-house team, not third-party contractors.

  • All systems are inspected and approved before handover.

  • The guarantee covers defects related to workmanship, giving you complete assurance that your structure will remain watertight.

The guarantee begins on completion and is issued alongside your handover documentation.

Maintenance & Aftercare

To maintain your 10-Year Workmanship Guarantee, a routine inspection should be carried out at least once per year — particularly for systems with sump pumps, drainage membranes, or exposed elements.
Our team offers maintenance packages that include:

  • Pump and channel inspections

  • Waterproofing integrity checks

  • System cleaning and performance testing

These visits ensure your system continues to perform exactly as designed, and your guarantee remains valid.

Quality Assurance

Our guarantee is only as strong as our process — and we take every step seriously.

Before we issue a guarantee, we ensure that:

  • The design is validated by our technical team.

  • The installation is supervised and inspected by our project management team.

  • The completed system is signed off and handed over with full documentation.

  • At the client’s request, we can provide an insurance-backed warranty supported by a reputable insurance company. This offers a meaningful level of protection, ensuring that any defects will be rectified even in the unlikely event that we are unable to fulfil our own guarantee

This strict process ensures long-term performance and accountability on every project we deliver.
