What Is Tanking and Why Is It Essential?
Tanking refers to the application of a waterproof barrier or proof membrane to the basement walls, cellar walls, and concrete floors of underground spaces. This process creates a sealed environment, blocking ground moisture and resisting hydrostatic pressure that often leads to dampness in buildings. When carried out correctly by qualified trades people, tanking services form the cornerstone of effective basement waterproofing.
As tanking specialists we assess your property to determine the right damp proofing method, ensuring maximum protection against excess water, mould growth, and structural damage.
Common Signs of Damp That Require Immediate Attention
Recognising the signs of damp early can prevent severe damage to your property. Our damp proofing surveyors look for:
- Damp patches or discoloured patches on internal walls
- Tide marks along the ground floor or up to a metre in height
- A persistent musty smell or musty odours
- Condensation on windows and cold surfaces
- Evidence of black mould, especially in corners or near floor junctions
- Peeling paint or damp proofing membranes bubbling under surfaces
These symptoms can stem from various types of damp, including damp condensation, penetrating damp, and rising damp.
Our Damp Proofing and Waterproofing Services
At CA Plasterers & Builders London, we offer a comprehensive range of damp treatment services and tanking solutions suitable for all types of properties, from modern flats to period homes and commercial buildings.
1. Cementitious Tanking
This heavy-duty solution uses cement-based tanking material to form a waterproof seal on masonry surfaces. It’s ideal for cellar dry conversions and underground spaces.
2. Cavity Drain Membranes (CDMs)
Perfect for managing water penetration, CDMs direct water into internal drainage systems, keeping the interior dry. This is the go-to system for areas with high groundwater levels.
3. Chemical Damp Proof Course
Our proof injection techniques using injection creams provide a barrier against rising damp by creating a damp-proof course within walls. This method is especially useful where traditional proof courses have failed.
4. Anti-Condensation Solutions
We improve ventilation by recommending extractor fans, double glazing, and proper ventilation strategies. For severe cases of excessive condensation, we apply anti-condensation paint or epoxy coatings on internal surfaces.
Types of Waterproofing Systems We Offer
Type A – Barrier Protection
Involves applying waterproof coatings or proof paint to exterior walls and interior surfaces, forming a protective layer against external repairs and moisture. This is a common solution for properties with moderate water vapour exposure.Type B – Structurally Integral Protection
Ideal for modern buildings, where the structure itself includes waterproofing methods like concrete additives and cavity wall insulation that resist moisture.Type C – Drainage Protection
This system utilises cavity drain membranes and active ground waterproofing measures to divert water safely away, ensuring a dry basement even under heavy rains or high hydrostatic pressure.Why Property Owners Choose CA Plasterers & Builders London
