They work with architects, surveyors, building contractors, as well as with householders directly, to provide complete survey, design and guaranteed installation services that carry a 10-year guarantee.

I'd like to let you know that your surveyor is a great ambassador for Renlon. He couldn't have been nicer and conducted a very thorough check of the flat. What's more, he was kind enough to wait for me to arrive home when public transport let me down, and he phoned my landlord to explain the cause of the problem upon my request.  People are very quick to give negative feedback, but I really feel that your surveyor deserves some positive recognition here - a great reflection on Renlon. Thanks again. Chloe

Renlon Ltd recently completed some damp proofing work as sub-contractor to JKS at my property in South East London.  My wife and I just wanted to reach out to say thank you to the technician who was here for a few days doing the injections and rendering. He was a thoroughly lovely bloke; he showed real care for the property while he was here and did a great job, fast and high quality. He's a credit to Renlon, as was the project manager and surveyor when they visited the property at various stages to review and give advice. I just wanted to say thanks to all involved. Jeremy

Your surveyor arrived on time to my property to answer some concerns I had regarding the Renlon tanking I have in my flat. The tanking has been in place since the early 90's but I needed advice regarding pipework installation. I was given suggestions and advice which was extremely helpful in addition to other suggestions which he noticed while looking at the tanking. Your surveyor is a credit to Renlon and an ambassador to excellent customer experience.  I would have no hesitation in recommending Renlon to others. Maria

Featured Projects

Grand Designs’ Healthy House, Richmond

Figure 1 Healthy House basement waterproofing

To provide a safe home environment for their children, who suffer from life threatening allergies, a couple embarked on a self-build project for Britain’s first ‘healthy home’. The project was featured on Channel 4’s Grand Designs in October 2018. 

Due to planning restrictions, the house was designed to be single story with a basement.  Careful consideration to the drainage and waterproofing design was critical to the overall success, as the main living areas would be effectively underground. 

Renlon undertook the waterproofing of the large basement, installing cavity wall and floor membrane, incorporating modular and perimeter drainage and a sump pump chamber to collect any potential water ingress diverting it to a sump from which it is pumped away

Storage Vaults Basement Tanking, Marylebone

Renlon carried out the refurbishment of the 12 under pavement vaults that became unusable due to the failure of a previous tanking system, which lead to water leakages and structural damage.  

With some of the vaults used to house services such as gas, electric and water throughout the building, the cabling and piping penetrations required a sealant flexible enough to allow for movement whilst remaining watertight.

To eliminate the long-term threat of water ingress, Renlon specified a structural waterproofing system to provide a watertight seal, transforming the vaults into dry, commercial storage spaces.

Liquid Gas Membrane System – Richmond Project

An old car maintenance garage is set to be the site for a new-build development of 4 homes in Richmond.   

To address contamination from previous ground gasses, Renlon designed a waterproofing strategy to provide a suitable gas barrier against the ingress of Methane, Carbon Dioxide, Radon, ground gas, VOC, air and moisture into buildings.
