Structural Waterproofing Systems

Sovereign offer a unique service within the waterproofing/basement conversion industry in that we are able to assist with your project from initial design through to full individual specification and the appointment of an approved contractor. 

Sovereign offers two forms of structural waterproofing system:

Hey’di K11 (Type A)

SovDrain (Type C)

The Sovereign Hey’di K11 System (Type A) is an alkali-resistant synthetically modified cement which is mixed with styrene-butadiene and water, producing a waterproof slurry coating preventing both damp and water penetration.

The chemicals in the slurry react, penetrate and fill off or block the capillaries, bonding onto the prepared surface, forming a strong monolithic bond enabling it to resist hydrostatic pressure. Lateral/penetrating damp in above and below ground situations can be resolved for both old properties and new buildings using the Sovereign Hey’di K11 Tanking System. The K11 Tanking System has proved to be highly successful for waterproofing many varying types of structure worldwide for many years.

Basement Tanking Systems is the creation of a watertight envelope as it must be assumed that water pressure will come to bear upon the structure at some point in its life – BS 8102 refers. Therefore with any below ground or retaining structure, cellar tanking should be applied to all surfaces below ground level, and ideally linked in with an effective damp proof course above ground level in order to achieve a continuous system.

The SovDrain Cavity Drainage Membrane System (Type C) uses advanced cavity drain membranes, proven specialist fixing and jointing technology, and leading-edge drainage and pumping stations. SovDrain is ideal for a wide variety of demanding above and below ground situations; providing a highly effective membrane system that acts as a barrier against the effects of water, damp and salt contamination enabling the area to be transformed into your desired valuable living space.

Both Sovereign’s Type A and Type C Systems have the benefit of third party accreditation in the form of BBA Certification and have been tried and tested for many years.

With thousands of written specifications produced annually there is clearly a requirement for professional guidance in cellar damp proofing and waterproofing solutions but remember when it comes to choosing a system it’s not “one size fits all”, rather

Sovereign also stocks a range of products including Pumping Stations, including accessories such as Power Backup and Alarms both are designed for use with the SovDrain Cavity Draining Membrane System, where a safe form of natural drainage is not available.
