What We Found
Given its storied history, it is no secret that the Rosewood Hotel London is an oasis of serenity amidst the hustle and bustle of downtown London. That being the case, this luxurious hotel should be maintained to meet the elevated standards guests have come to expect when in residence, so we were called upon to examine a matter in the basement area. After completing our extensive evaluation, we discovered evidence of dampness, which meant basement waterproofing was needed for it to become usable again.
Types of Damp
In our experience, there are generally two types of damp that are responsible for moisture damage in basements and cellars: penetrating damp and rising damp. Penetrating damp is one of the most insidious and damaging issues you can have in your home. Its sources are far-reaching, from missing roof tiles or burst pipes to loose exterior plastering and unsealed windows. It’s not always easy to pinpoint the source, but if you notice any signs of moisture on your walls or ceilings, determining the source should be a top priority before long-term damage occurs.
On the other hand, rising damp is caused by moisture below the wall, usually from the ground, being pulled into the material. It often comes from a failed damp proof course that has deteriorated over time or has been incorrectly installed. Another structure, such as steps that have been damaged, can allow the damp to be carried into the porous walls.
Rising damp can also occur when wall construction ages. The bricks become more permeable, developing cracks in the material and creating channels that pull up moisture into the wall—known as capillary action. If a wall was constructed badly, or a long time ago, then rising damp can be a real problem.
How We Fixed the Issue
In this instance, we removed all damaged surface plaster. Following that, we applied a specific waterproof basement tanking render before we proceeded with replastering the large basement. Unfortunately, the floor was also in need of repair as a result of water damage. So, as a solution to that particular issue, we added a new screed waterproof floor throughout the affected basement area, so that it would be good as new!

These are the tools we use
A damp meter
A damp meter is a diagnostic tool used to detect and measure moisture levels within building materials such as plaster, brick, timber, and concrete.
Borescope camera
borescope camera is a small inspection camera attached to a flexible semi-rigid cable that allows you to see inside areas that are otherwise inaccessible.
Inspection Drone
A drone is a remotely operated aerial device equipped with a camera that allows visual inspection from above without the need for scaffolding or ladder.
Air Humidity Sensor
Air humidity sensor measures the amount of moisture present in the air, expressed as relative humidity (RH) in percentage. It helps determine whether indoor conditions are contributing to condensation, mould growth, or damp-related issues.
Thermal Imaging Camera
A thermal imaging camera detects temperature differences on surfaces by using infrared technology to produce a heat map image. In damp investigations, it helps identify cold spots, moisture intrusion, insulation defects, thermal bridging and leaks.
Air Flow Ventilation Detector
An air flow ventilation detector measures the movement and volume of air passing through vents, extractor fans, and air bricks. It confirms whether ventilation systems are working properly and achieving adequate air changes within a room. Poor airflow leads to trapped moisture, high humidity, condensation on cold surfaces, and ultimately mould growth.
Mould Swab Test Kit
A mould swab test is carried out to confirm the presence of hidden mould growth and identify the specific species involved. Surface mould is not always visible, especially behind furniture, inside cavities, or within ventilation systems. Laboratory analysis of a swab sample determines whether active mould spores are present and what type they are, which helps assess potential health risks and decide the correct remediation approach rather than relying on visual assumption alone.
Plaster Salt Analysis Lab
Laboratory analysis of plaster is used to identify the type of salts present within the material, typically chlorides and nitrates. The presence and concentration of these salts help determine whether the moisture source is consistent with rising damp, ground contamination, or another forms [sic] of water ingress. such as mains water leak, This removes guesswork and prevents misdiagnosis, ensuring the correct remedial treatment is specified rather than applying unnecessary or ineffective solutions.
