Cavity drain system protects sea front property from storm floods! WATCH VIDEO FOOTAGE!

Tuesday, January 14th, 2014

A waterfront property at West Kirby on the Wirrall was recently threatened during a storm by flooding from the heavy seas.

The owner had recently converted part of her basement garage to a bedroom whilst leaving the remainder for storage. During the heavy storm, sea water crashed into the front of the property filling the unconverted part of the garage with approximately five feet of sea water!  Fortunately Dampshield of Buckley (01244 537236) had installed a Platon cavity drain membrane and Aqua Pump system as part of the bedroom conversion that meant the new bedroom remained completely dry.

Both neighbouring properties were completely flooded and the property owner was extremely happy with, and relieved by, the performance of the waterproofing system installed.

Watch this video taken in front of the property during the storm to see just how severe the weather conditions were!

The trend is for Triton membranes in new build schemes

Monday, January 13th, 2014

The new year is seeing Platon cavity drain membranes from Triton being  installed as waterproofing systems on new build projects across the UK. Here’s an example of external basement waterproofing using Platon Double Drain and Triton TT Vapour Membrane on a domestic new build in Farnham, Surrey.  Platon Multi and Platon P20 will be installed on the internal walls and floors.

Aerial view of property (terrace top right) during flooding

Determined not to sell the flood-prone riverside property he loved, the owner turned to Triton for the specification and supply of effective flood resilience measures. The property, built on the banks of the River Severn in Worcester, had consistently been the victim of flooding since its construction and, just before renovation works, severe flooding caused the water level to rise above the ground floor window sills.  Prior to renovation, the original floor slab was cracked and the dpm had failed. There was constant water ingress into the ground floor whenever the river levels rose or during heavy rain.

Triton specified a system comprising Aqua Pumps and Aqua Channel conduit, installed in conjunction with a sealed system of Platon Cavity Drain Membranes – more normally specified in basement waterproofing applications.  The system is designed to direct any water entering from behind the profiled membrane into the Aqua Channel conduit around the perimeter of the property to either of two sumps fitted into the floor. Flushing points were incorporated within the Aqua Channel to enable ongoing maintenance of the system and flushing through with Triton’s X5 Sanitiser if required after ingress of contaminated water.

In view of the high risk of severe flooding of this property, Triton recommended two pumps were installed in each sump chamber to guard against mechanical failure of the first pump and to provide additional pumping capacity when required.   Because the success of this system depends entirely on the performance of the pumps, audio and visual high water alarms have also been installed to each sump chamber to ensure the owner can respond to any power failure by the operation of a stand by generator.

The Aqua Channel conduit was installed into a channel preformed by shuttering before the new slab was poured.  The slab was then lined with high capacity Platon P20 membrane, followed by a reinforced screed and insulation layer, before an underfloor heating system was installed throughout the ground floor.  (Triton’s TT Admix is often specified as a waterproofer within the floor slab mix in this type of application.) Timber floors have since been laid to the living and dining rooms and ceramic tiles in the kitchen.   Platon Plasterbase and P5 membranes were fitted to the external and party walls before direct plastering or dry lining as required.

No more drying out

This system was tried and tested even before renovation works were complete when heavy rain caused the neighbouring property to flood and ground seepage water entered through the party wall.  All water remained behind the membranes and was pumped away from the property which, for the first time after a flooding episode, remained dry.  Previously the property owner would vacate the ground floor after a flood, and wait for it to dry out before redecorating.

External steel flood barriers have also been purchased for the property as a measure against very high water levels and are fitted when required in front of ground floor windows and doors, and at each end of the pathway between the terraces.  It takes around half an hour to install the barriers and normally householders are given around three to four hours notice by the local authority before they are required.  However flood warnings are normally in place two to three days before this.  The owners of the properties in the terrace help each other out by installing barriers for anyone who is away.

The owners of some neighbouring properties have decided to sell their homes (at vastly reduced prices) due to their vulnerability to flooding and the consequential damage and upheaval.   But, the combination of the flood resilience measures supplied by Triton, suitable flood defence barriers and non return valves to service entry pipes, has brought peace of mind to the owner of this property. The risk of future flooding has been dramatically reduced and, should water enter behind the membrane system, there will no longer be the need to vacate the property and endure a long drying out period.

Basement Information Centre’s waterproofing guide – download for free from here!

The Basement Information Centre’s ‘Waterproofing Design Guide – general guidance to BS 8102: 2009′ is a useful document. You can use the link below to access the free download:

The 44 page publication examines the factors to consider when deciding on the form of basement construction, and types of waterproofing for single-storey domestic basements.

It provides guidance on the form and characteristics of the main categories of waterproofing systems: bonded sheet membranes, bentonite clay active membranes, liquid-applied membranes, mastic asphalt, cementitious proprietary multi-coat renders, toppings, coatings, and cavity drain systems.

It also contains information on soil characteristics and detailed illustrations relating to drainage, waterproofing and means of assessing risk.

The guidance in this publication follows the principles given in BS 8102:2009, which should be referred to for more recommendations and guidance on methods of dealing with and preventing the entry of water from surrounding ground into a structure below ground level for both shallow and deep basements.
