Our Waterproofing/Dampproofing Installation Process

Step 1 — Free Site Survey
We visit your property, assess the foundation and surrounding exterior walls, and identify any areas vulnerable to moisture or water ingress.

Step 2 — Inspection & Solution Planning
We evaluate drainage conditions and recommend the most effective damp proofing method and materials for your property.

Step 3 — Excavation & Surface Preparation
We carefully excavate around the foundation walls and prepare the surface to ensure proper adhesion and long-term performance.

Step 4 — Damp Proofing Application
A high-quality waterproof coating or membrane is applied to create a strong barrier against moisture.

Step 5 — Backfill & Final Clean Up
We backfill the area, restore the surroundings, and leave your property clean, secure, and protected.
