External Waterproofing & Tanking Systems

We apply professional external waterproofing membranes and tanking systems to below-ground structures, creating permanent barriers against groundwater ingress.

Liquid Applied Membranes

Cold-applied liquid waterproofing systems that cure to form seamless, flexible barriers. Ideal for complex details, penetrations, and irregular surfaces on retaining walls and basement exteriors.

Sheet Membrane Systems

High-performance HDPE and bituminous sheet membranes mechanically fixed or torch-applied to below-ground walls, providing robust protection against hydrostatic water pressure.

Cementitious Tanking

Polymer-modified cement-based waterproofing slurries applied to external foundation walls, creating crystalline barriers that resist water pressure while remaining breathable.

Drainage Composites

Geocomposite drainage boards installed over waterproofing membranes to channel groundwater safely to perimeter drains, reducing hydrostatic pressure on basement walls.

Perimeter Land Drains

French drain systems with perforated pipes and gravel surrounds installed at foundation level, collecting and diverting groundwater away from structures before it can penetrate walls.

Structural Waterproofing

Integrated waterproofing strategies combining external membranes, drainage layers, and structural protection boards to BS 8102 Grade 3 standards for critical applications.

External Waterproofing Installation Process

01

Excavation & Exposure

Existing ground is excavated adjacent to foundation walls to expose below-ground surfaces. Temporary shoring installed if required for safety and access.

02

Surface Preparation

Walls are cleaned, defects repaired with cementitious mortars, sharp edges removed, and surfaces primed to receive waterproofing membranes according to manufacturer specifications.

03

Membrane Application

Waterproofing membranes are applied from footing level upwards with proper overlaps, sealed joints, and protection at penetrations. Drainage layers added over membranes.

04

Drainage & Backfill

Perimeter land drains installed at footing level, protection boards fixed over membranes, and excavations backfilled with free-draining granular material to prevent water accumulation.

Frequently Asked Questions

How much does external waterproofing cost?

External waterproofing costs depend on wall height, excavation depth, membrane type, access constraints, and drainage requirements. Typical residential basement waterproofing ranges from £150-£250 per linear metre including excavation and reinstatement. Commercial projects vary based on scale and specification.

When is external waterproofing better than internal solutions?

External waterproofing is the gold standard as it stops water before it enters the structure, protects the concrete itself, and doesn't reduce internal space. It's essential for new builds and recommended when excavation is already required for other works. Internal systems are more practical for existing buildings where excavation is prohibitively expensive.

How long does external waterproofing last?

When properly installed with appropriate protection and drainage, external waterproofing systems have 25-50+ year lifespans. Sheet membranes and liquid-applied systems backed by manufacturer guarantees typically last the lifetime of the structure when correctly specified and installed.

Can external waterproofing be added to existing buildings?

Yes, external waterproofing can be retrofitted to existing buildings through excavation alongside walls. This is often combined with underpinning, foundation repairs, or basement conversions to maximise value from the excavation works. Access and adjacent structures must be considered during design.

Do I need land drains with external waterproofing?

Perimeter land drains are highly recommended alongside external waterproofing membranes. They reduce hydrostatic water pressure against walls by channelling groundwater away before it can accumulate. This dramatically improves membrane longevity and system effectiveness, especially in high water table conditions.
