Tanking Services in London – Commercial Waterproofing by Cam Support

Specialist Structural Tanking & Waterproofing for Commercial and Industrial Buildings

At Cam Support, we provide expert tanking services in London designed to protect commercial and industrial structures from water ingress, rising damp, and structural moisture issues. With years of experience in commercial environments—from sub-basements and plant rooms to tunnels, service voids, and utility spaces—our tanking solutions ensure long-term protection and compliance with building regulations.

We work directly with contractors, facility managers, and structural engineers to deliver waterproofing systems that are effective, discreet, and built to last.

What Are Tanking Services?

Tanking makes a structure completely waterproof by applying a protective barrier or drainage system to vulnerable areas. It is an essential solution in commercial and industrial properties where any water ingress could threaten structural integrity, disrupt operations, or cause costly damage to assets and equipment.

Tanking is typically required in:

Basements and sub-ground floors
Underground plant rooms and service voids
Retaining walls, lift pits, and structural recesses
Utility corridors and undercrofts
Tunnels, culverts, and foundations

At Cam Support, we specialise in both positive-side (external) and negative-side (internal) tanking applications for existing and new-build commercial projects.

Our Commercial Tanking Solutions

Plant Room and Service Void Waterproofing

Plant rooms and service voids are mission-critical areas in most commercial buildings. Leaks in these areas can affect HVAC systems, power controls, fire suppression equipment, and more.

Our tanking services for plant rooms include:

High-strength waterproof membranes
Concrete joint and floor junction sealing
Structural tanking to pits, risers, and access voids
Solutions compatible with electrical and mechanical environments
Long-term flood protection and pump integration

We coordinate with your M&E contractors to protect all penetrations and interfaces.

Basement and Sub-Structure Tanking

Basement tanking is essential for commercial buildings that use underground space for storage, services, or equipment. Water ingress in these areas can cause damage and compromise electrical systems, leading to costly downtime.

Cam Support offers:

Cementitious tanking slurry systems
Type C cavity drain membrane installations
Internal wall and floor coatings for negative-side protection
External pre-applied membranes for new builds
Internal rendering and tanking barriers for retrofit works

We also install sump and pump systems where necessary to support long-term drainage.

Retaining Walls and Lift Pit Tanking

Retaining walls and structural voids require waterproofing that can handle hydrostatic pressure over time. Our solutions provide long-lasting, robust protection in these high-risk areas.

Cam Support tanking systems for walls and pits include:

Exterior waterproof membrane wrapping (Type A)
Internal slurry and render applications (Type A/Type C hybrid)
Epoxy coatings and injection sealing for crack repairs
Drainage board and channel installation
Waterproof expansion joints and detailing

Tanking for New Build Projects

New commercial developments in London often require tanking to concrete substructures, basements, and podium decks. We work alongside your structural engineers and contractors to implement effective waterproofing before handover.

Our services include:

Pre-applied tanking membranes on foundations
Waterproofing lift pits and concrete bases
Installation of protection boards and insulation
Detailing movement joints, pipe penetrations, and interfaces
Complete post-installation reports and compliance documents

Early-stage tanking saves money in the long term and ensures regulatory approval.

Our Tanking Systems – Type A, B & C

Type A

Barrier Tanking Systems

Type A systems create a physical barrier to prevent water from penetrating walls or floors. These are common in retrofit or negative-side scenarios.

Type B

Structural Integral Systems

Type B protection is used in new builds. It involves using waterproof concrete and joint detailing to make the structure watertight.

Type C

Cavity Drainage Membranes

These systems manage water ingress by controlling and redirecting it to a safe discharge point.
