Type A Structural Waterproofing – External Membranes, Drainage & Vapour Control
Clever Shield supplies a professional range of Type A structural waterproofing systems, designed to protect basements, foundations, and retaining walls from water ingress at source. Type A systems rely on external membranes and drainage layers to form a continuous barrier that prevents water penetration and supports long-term structural durability.
Alongside external waterproofing membranes, this collection also includes vapour control layers (VCLs), used within below-ground and ground-bearing structures to manage moisture vapour movement and reduce condensation risk.
External Waterproofing Membranes
-
Liquid-Applied Waterproofing Membranes
Seamless, fully bonded systems that conform to complex details and provide continuous external protection. -
Sheet Waterproofing Membranes
Bitumen, PVC, elastomeric and composite membranes for consistent thickness and high-performance waterproofing. -
Self-Adhesive & Torch-On Membranes
Ideal for detailing, joints, penetrations and high-risk areas where robust adhesion is required.
External Drainage & Water Management
-
Dimpled Drainage Membranes
Relieve hydrostatic pressure by allowing groundwater to drain safely away from the structure. -
Geocomposite Drainage Membranes
Combined drainage cores and geotextiles for filtration and controlled water movement. -
External Drainage Solutions
Designed to divert groundwater away from foundations and reduce long-term load on waterproofing systems.
Vapour Control Layers (VCLs)
-
Moisture Vapour Barriers
Control vapour migration within ground-bearing and below-ground structures. -
Sub-slab & Foundation Applications
Suitable for use beneath concrete slabs and within foundation build-ups. -
Condensation Risk Reduction
Supports internal finishes and improves long-term building performance.
Note: Vapour control layers manage moisture vapour only and do not act as primary waterproofing systems.

Quick FAQs
What is Type A structural waterproofing?
Type A waterproofing uses external barriers such as membranes and coatings to prevent water entering the structure. It is installed on the outside face of basements, foundations and retaining walls.
Do I need drainage with Type A waterproofing?
In many cases, yes. External drainage membranes and systems help relieve groundwater pressure and improve the long-term performance of the waterproofing barrier.
Are vapour control layers the same as waterproofing membranes?
No. Vapour control layers manage moisture vapour movement but do not stop liquid water ingress. They are used as part of a wider build-up, not as primary waterproofing.
Can you help select the correct Type A system?
Yes. Call 01268 472358 for help choosing membranes, drainage layers and compatible accessories for your project.
