Kenwood Plc undertake a wide range of basement waterproofing operations. As leading specialists in below ground waterproofing, our treatments include basements, under street vaults, cellars, and lower ground floor accommodation, such as garden flats.

Treatment is undertaken either by providing a complete system to a new or existing basement, or by undertaking repairs to damp walls. Often tanking is used to overcome problems associated with high ground levels such as abutting pavements or high garden / patio levels.

Kenwood tanking systems are very effective methods of waterproofing below ground structures, using either the Kenwood SWS Tanking System ©, Kenwood Rapid © or a Cavity Drain Membrane System. We are fully conversant with all tanking and waterproofing methods and offer a full range of treatment operations to meet your needs. Our treatments are fully guaranteed and provide an excellent method of maintaining or utilising below ground structures. Tanking cellars and basements can be an cost effective way of increasing living space and can increase the value of a property.

Kenwood SWS Tanking System

Basement waterproofing with Kenwood SWS (Structural waterproofing system) involves removal of the existing plasters and paints etc., using breakers, mechanical surface scarrifiers and needle gunning to remove latent coatings and to provide a sound substrate to receive the waterproofing system. Masonry is then prepared and Kenwood SWS multi-coat tanking slurry is applied to the masonry, by either brush, low pressure spray or trowel depending on the particular project and substrate. Tanking a cellar or a basement is a process that requires special attention as the tanking method will depend on the stability of the basement walls, the nature of the structure and the prospective use of that space.

Complete systems may include solid ceiling soffits, walls & floors

Kenwood SWS is ideal for use on basement rooms, cellars and below ground accommodation. Following the completion of the tanking application, the walls are replastered using Kenwood waterproof rendering system and skimmed with plaster ready to receive decoration. Kenwood SWS tanking system is one of the high quality tanking system and once the process is completed, rooms may become usable storage space or an extra guest bedroom where appropriate.

A key feature of Kenwood SWS is that it does not normally require a sump or pump to be installed and maintained, which is typically required with a cavity drain membrane system.

Kenwood Rapid Setting Tanking System

Kenwood Rapid Setting Tanking System is our premium waterproofing system, specifically designed for use in understreet vaults.

Treatment involves the removal of existing surface materials, including plasters and paints etc. The masonry is then consolidated with the application of Kenwood Rapid, which is a high strength, fast setting and curing concrete, which consists of cements, binders and dried aggregates.

Kenwood Rapid has excellent resistance to water and sulphates, along with a low modulus of elasticity which is particularly effective on friable, poor quality substrates such as those encountered in pavement vaults.

Kenwood Rapid is capable of setting under water and therefore ensures complete curing in exceptionally damp conditions.

The design of Kenwood Rapid Tanking System has the added benefit of not requiring a sump pump to be installed and maintained. Following the application of Kenwood Rapid, the walls are then treated with Kenwood SWS and Kenwood Waterproof Rendering System, ready for decoration as required.

Cavity Drain Membrane

Cavity drain membranes involve fixing a studded membrane to the substrate, incorporating drainage arrangements in the form of perimeter drainage, channels and gulleys. With a cavity drain membrane, this drainage is essential to discharge the water from behind the membrane into a drain or sump pump.

The drainage channels and pump must remain accessible to allow for periodic maintenance. We recommend that the pump is fitted with an alarm to activate in the event of failure, as membrane systems rely upon the pump to discharge the accumulated water or flooding can occur.

The membrane joints are heat welded to ensure a waterproof seal and the completed membrane is used to create a dry internal envelope, which is then plastered using an independent plaster frame and the floor covered with either a timber sheet floor or cement screed as required.

Kenwood SWS Tanking and Kenwood Rapid are typically guaranteed for 10 years. Additional Insurance backed guarantees are also available from the market leading insurers.
