We provide specialist advice on Basement Waterproofing Design, Rising Damp and
Timber Infestation

We work in partnership with

Architects

As an architect you will no doubt often come across many situations where specialist waterproofing knowledge is required. It may be to provide additional space for a new build where the footprint of the site is limited. A good alternative option could be to go below ground. This could accommodate gyms, indoor pools or home cinemas which are very commonly built in basements these days.

Another issue that you may frequently face is the conversion of existing basements and cellars into living spaces. Ensuring they are kept dry is critical especially where they could be used for the storage of valuable items.

Surveyors

For surveyors we are able to provide specialist advice and surveys on:

  • Waterproofing
  • Rising Damp
  • Timber Treatments for Wet and Dry Rot

Our own Renlon surveyors are some of the most highly experienced surveyors in the business; they will quickly identify Rising Damp, or Wet and Dry Rot in the Timbers. Once the problem area is located we can then provide the necessary advice on how to treat the affected area, and prevent any reoccurrence.

Our Specialist Services

Basement Waterproofing

Every waterproofing project requires its own assessment and designed solution depending on the conditions present. There are just two simple objectives; prevent water penetration or manage effectively any water or moisture that comes through the structure.

We offer a variety of solutions which utilise advanced cavity drain systems, drainage channels and pump technology or cementitious tanking materials. We prevent external water that is penetrating the structure by applying a render to the internal structure. Alternatively we manage what water does come through the structure using a cavity drain system and pump technology.

Timber Infestation

Traditional building methods combined with a damp temperate climate will increase the risk of insect and fungal attack within structural timber.

Renlon surveyors are fully trained to identify wet and dry rot in a structure. If present, we begin by identifying the moisture source, so we can prevent further outbreaks. We do this by treating the areas of masonry affected and salvageable timbers within the vicinity using the appropriate fungicides.

Rising Damp

Rising damp can occur where a structural wall is in contact with the ground and where there is no existing damp proof course, or the existing one has been damaged. Dampness can rise up the wall creating a damp internal environment and damaging internal decorative finishes.

Where this has occurred we can rectify the problem by injecting a new chemical damp proof course and rendering walls to remove the damaging effects of hygroscopic salts.

Testimonials

  • Renlon were employed to undertake the waterproofing, tanking and damp protection works on Wates’ prestigious project for The London Business School at The Old Marylebone Town Hall. Being the Specialists they are in this field, they worked closely with the Wates Construction Project Team and the design team from Sheppard Robson Architects to come up with the best solutions practicable for each situation to ensure that all water ingress was eradicated from the 100-year-old building, that had suffered badly with damp problems over the preceding 10 years or so. We found the Renlon team to be helpful and the operatives were diligent in ensuring that their installation was being carried out to the highest standards to ensure that no further ingress ensued. I would have no hesitation in using Renlon again and indeed look forward to working with their team again.

    Director at Wates
  • Richardsons (Nyewood) Ltd have worked with Renlon since 2010 on 20 plus contracts in London for several established property management companies. We recommend Renlon Ltd as they are a long-established company with a proven track record. Their surveyors are responsive and willing to discuss options to assist the building process/programme without any reduction in specification. Their work is of a good standard and in all the years we have worked together there have been no issues and therefore no requirement to call upon the insurance backed guarantees.

  • I am writing to thank you for Renlon's continuous support at Carshalton College, within our Plastering department. I have been speaking to the Plastering Tutor - Richard Childs who informs me that having Renlon supporting the Plastering department in their practical sessions, gives the students a great opportunity to broaden their skills, and meet somebody working within the industry. Having spoken to Richard, the feedback from the plastering students shows they greatly value Kevin showing them, and explaining what the Plastering and Rendering industry requires from them, and explaining what would be required from them in the current Plastering and Rendering Industry work environment.
