Delta Basement Waterproofing of Luxury North London Property

October 2017

Luxury North London Property

Overview

Our Technical Consultant, Paul Callaghan was approached by Kings of Essex to give assistance on a particularly technically complicated project. Kings of Essex have previously worked with Paul on waterproofing projects and knew Paul would be able to furnish them with a waterproofing solution which could be incorporated in this complex waterproofing challenge.
The project in question was a new build luxury property in North London, providing almost 17,000 sq ft of accommodation, set over four floors. This spectacular mansion is refined in luxury with marbled flooring, atrium hallway, several bedrooms, a home cinema, luxury spa, swimming pool, massage, nail bar and hair dressing salon, entertaining rooms, formal and informal dining rooms.
High volumes of hydrostatic water pressure was bearing on the structure, which was causing the property to suffer severe water ingress through construction joints.
The property when constructed was built at a low level, it sits lower than the neighbouring properties adding to the hydrostatic water pressure issue. An additional problem was the property had been built without a waterbar/hydrophilic strip. A waterbar or hydrophilic strip will expand when a structure experiences water ingress, slowing down/stopping water ingress. It is good building practice to incorporate a waterbar/hydrophilic strip to any below ground structure.
The property when built incorporated a cavity drain membrane system (not Delta’s) and sump pump units.
The rooms to the basement considered of: swimming pool area, spa, massage, nail bar and hair dressing salon, comms room, electrical intake room and maids quarters.
The electrical intake room was exceptionally flooded which raised a health and safety issues for the occupiers of the property, leading Kings of Essex needing to take immediate remedial action.

Methodology
The project, due to its size and complexity was set into phases.
The first phase was to ensure the property was made safe from electrical dangers.
The second phase was to stop the water ingress. Once the structure had been stripped back to its concrete core, the water ingress to construction joints was addressed.
A waterbar/hydrophilic strip cannot be retrofitted, meaning this project could not allow for installation. Paul recommended using the Koster brand of concrete repair solutions to limit and slow down the water ingress experienced.
Paul’s first recommendation was to use Koster KD 2 Blitz – waterstop to the construction joints. Koster KD Blitz Waterstop, stops active water ingress and safely seals off pressurized water from the negative side. Koster KD 2 Blitz is highly reactive with an extremely short setting time (active water leakages are sealed within seconds).
Once the construction joints were sealed Paul suggested applications of Koster NB1 and Koster Repair Motar Plus. KD Blitz was added as a secondary line of defence with NB1 coated to external walls throughout the basement structure to stop any water ingress (“locking down the structure”).
Consideration was given to managing future water ingress issues. Paul suggested adding additional sump pump stations throughout the structure. Paul met with Delta’s partner company PPS (Package Pump Systems Limited) on site to explore options.
Delta’s MS20 offered a perfect solution to the floor design, with its 20mm stud it is ideally equipped to deal with the volume of water ingress. The next phase of the project is for installation of the same.

System Components
Paul recommended:
Koster KD 2 Blitz – waterstop
Koster NB1
Koster Repair Motar Plus
Delta MS20
Delta MS500
Delta AlertMaxx2
Delta Sump Pump Stations
The AlertMaxx2 with its wifi capabilities would allow the client a monitoring system. The client opted to subscribe to PumpAware allowing PPS to monitor the property 24/7/365.
Case Study Review
Les King and Peter Colella were overjoyed with Paul’s understanding and no nonsense approach.
Paul’s on site attendance and eye for detail were exactly what was needed for this project. Paul created a waterproofing system which would allow for the issues caused by the hydrostatic water ingress to be addressed.
By incorporating Paul’s waterproofing solutions, water ingress was nullified.
The Delta membrane system will be installed within the next 6 weeks and we look forward to revisiting this project as it evolves.

Delta attends BRE Urban Flood Resilience Innovation

September 2017

Delta Membrane Systems Limited attends the BRE Urban Flood Resilience Innovation, Innovation-UK Project:Dissemination Event, BRE Innovation Park, Ravenscraig, 7 September 2017.

As part of Delta’s continuing research and development programme into flood resilient systems, our Technical Consultant, Michael Vernon was pleased to attend the BRE Urban Flood Resilience Dissemination Seminar on Thursday 7 September at the BRE Innovation Park, Ravenscraig.

The event was hosted by the Director of the BRE Dr Stephen Garvin. Dr Garvin was closely involved in the development of the Flood Resilient Repair Home at BRE Innovation Park, Watford.

Other speakers included Rob Dakin of AXA Insurance and Dermot McNally of Lexis Nexis.

The purpose of the event was to give an insight into considerations that Insurance companies take into account when considering flood risk and awarding of insurance policies. It also gave a strong indication of the types of technical criteria and resilient measures that insurance companies will be looking for in the future, including homes and businesses where Delta leak stopping, cavity drainage and sump pump technology can be used to protect buildings from flooding (Flood Resistance) and to drain and mitigate the effects of flooding should water enter a building (Flood Resilience).

Delta products, (cavity membranes and drainage products) can be used not only to block or slow down water but also to drastically speed up re-occupation time after a flood event. For example, Delta’s unique air gap technology not only enables water to drain away, it also allows structures to continue to dry out passively long after the building has been re-occupied, so protecting new finishes and saving huge amounts of insurance company money which would otherwise be diverted to providing temporary accommodation for residents and enabling residents to get back to their homes and businesses sooner. Delta products can be used and integrated together to comply with design guidance given in BS85500:2015 Flood Resistant and Resilient Construction – Guide to Improving the Flood Performance of Buildings.

Dr Garvin also introduced the concept of the “Property Flood Resilient Database”, which is a project currently under development with BRE, AXA Insurance and Lexis Nexis (the database consultants). In essence, the Property Flood Resilient Database (PFRd) will be a practical IT and web based tool that insurance companies can use to assess flood risk to any property in the United Kingdom. The risk assessment is formed as part of a “points score” based system. Points indicating risk factors will be accrued or subtracted on the basis of location, area flood event history, form of construction, installed structural flood resilience measures, flood resilient internal finishes etc.

The event also comprised a lively debate regarding potential design responsibility, potential liability, qualified installers, design rationale and what criteria should be met by future Flood Surveyors.

Delta Membrane Systems Limited is pleased to offer support where needed and to be involved in the technical and wider industry debates that are currently moulding this relatively young industry sector. Flooding is a growing threat and a potentially long term and devastating blight on people’s lives. Delta Membrane Systems Limited is proud to be at the cutting edge of flood resilience construction and research, bringing safety and security to people’s homes and businesses.
