Preventing Water Ingress & Damp for Long-Term Structural Protection

Basements and below-ground structures are highly susceptible to water ingress, as groundwater pressure, poor drainage, and foundation cracks can allow moisture to penetrate walls, floors, and underground spaces. Without effective waterproofing, this can lead to flooding, damp, mold growth, and structural deterioration, significantly impacting building safety and usability.

At Peak Access Abseilers London, we provide specialist basement and below-ground waterproofing solutions, ensuring long-term protection against water damage. Using BS 8102-compliant tanking systems, cavity drain membranes, and resin injection techniques, we create a robust waterproof barrier that protects residential, commercial, and industrial underground spaces.
