Basement Tanking & Basement Waterproofing Services

The condition of a basement is often overlooked when first moving into a property, but over time, if it is not waterproofed,  basement tanking services can be expensive. Structural waterproofing, is imperative for your house and it can be applied internally or externally as no two houses are the same.


At Timkon, we provide three types of structural waterproofing services that can protect your basement from any future issues:

Type A – Basement Tanking

Type A waterproofing is commonly known as ‘basement tanking’ and usually comprises of multi coat renders, cement-based coatings, bituminous paints or epoxy coatings. Like all our basement waterproofing, this can be applied internally or externally, but the areas worked on must be cleared of any defects for Type A to work. All walls and floors must be clean to protect renders, plasters and other coatings applied.

Type B – Concrete Waterproofing

Type B waterproofing is integral to the structure; comprised of concrete. There are inherent weaknesses in structures at joints and seams which are the most likely points to fail and allow penetration to occur. When they fail, they are virtually impossible to repair. Our services ensure that your structure is repaired before any permanent damage can be done.

Type C – Cavity Membrane

Type C waterproofing is a water management system that enables the water to flow freely between the cavity drain membrane and the wall structure. We mechanically secure the system to the walls with perimeter draining that can direct flow away from the internal structure. These are the simplest forms of basement tanking water management and have been effective for many decades.


Not only can we structurally waterproof your basement, but our services stretch as far as penetrating damp treatmentrising damp treatment as well as wall condensation control. We are also a re-plastering specialist and can plaster your damp walls and ensure our 20 year guarantee on all of our work upholds, meaning that our damp proofing services will be the least of your worries.
