Lambeth Living Warm Roof & Balcony Waterproofing Applications - Prokol Refurbishment Package Prokol POLYMERS UK DIRECT Manufacturer OF HIGH PERFORMANCE hYDROPHOBIC SEAMLESS LIQUID MEMBRANES - MINIMUM 30 YEAR MANUFACTURER WARRANTY

Working In Partnership with

Prokol Polymers UK - Mears & Lambeth Local Housing Authority Working Together

Prokol Polymers UK have been working with Lambeth as a client for over twenty five years, initially we were specified by a main contractor into Lambeth Council with our 8 second cure CE Certified walkway coatings. This overcoat or Prokol regeneration structural waterproof coating with anti slip was applied to 3000 m2 of communal cantilever walkway nearly 27 years ago. That coating was Inspected and I - audited for performance last year by a Prokol quality inspector at year 26 and had worn .only 1 of a micron over that period, the 136T seamless fast cure asphalt walkway coating gave the client a fast whole of life zero maintenance application with an initial 20 year manufacturer warranty, today that application is as good as the day it was applied by the approved applicators and warranty extended another 20 years so 40 in total. Prokol Polymers are working with end user and asset owner to develop key high performance product solutions which remove the need for future maintenance and service, and that would regenerate existing substrates without the need of costly removal and environmental impact with contaminant waste.

New Lambeth External Works Package Valued at £3.5m External -Structural Waterproofing

Roupell Estate Lambeth

Lambeth Living had long standing issues with life expectancy and warranties with their existing waterproofing supplier, small print in the suppliers warranties meant that due to the lack of maintenance, things like costly roof replacements had no cover when failure occurred. The maintenance stipulated was to constantly clear any to roof plant growth & sitting water from blocked drains, also clearing blocked drains to ensure no water build up on the felt membrane. Choosing to close the link and work direct with a manufacturer Prokol UK were requested to attend a meeting with the client project managers to identify and demonstrate how Prokol hydrophobic membranes operate in the same conditions but without any maintenance clauses still achieving long term manufacturer warranties in excess of 50 years.

Once the in-depth technical consultation was complete with Prokol explaining how hydrophobic seamless membranes were superior, and showing the client existing projects that had been in service over 15 years without any issues or maintenance. Suitably Impressed Prokol were specified by Lambeth Living to envelope multiple buildings suffering high levels of structural decay from water ingress. This large London based housing estate required our specialist range of structural asset waterproof Pure Polymers, upgrades to all roof areas included applications both warm and cold. Also included in the package were seamless waterproofing overlay applications to existing asphalt communal walkways and private balconies.

Key Product Attributes in High Traffic Areas

Prokol specified for these communal walkway applications a Pure Polyurea 136T - Which is a Structural Waterproofing Application with - 100% Solids - 8 Second Cure - 330% Elongation - High Level of Anti Slip without Aggregate Broadcast - One Single Application - No Down Time Ready For Traffic Even During Application - Zero VOC's - No Odour - Warrington Fire Certified

Prokol 136T Ideal Coating System when Fire Exit & Escape Need to Remain Fully Active

Prokol Polymers 8 Second Cure 136T Floor Application 330% Elongation - Anti Slip No Aggregates Used - One Single Application

Prokol Had to Work with New Handrail Fixing Designs To Ensure The Structural Waterproofing Membrane Created a Continuous Tanked Finish, & Cover Both Substrate Mediums - Asphat To Metal. Prokol Specified Corrosion Inhibiting Primers That Were Appplied to the Base Sections of Metal Hadrails Where They Normally Fail and Degrade Causing Safety Issue & Costly Replacement. This Method is Four Times More Effective Than Standard Coatings Such As Paints, Powder Coating or Enamel Which Are Not Flexible, High Elongation Properties in The Prokol Membrane Were Key When Dealing with Transitional Details from Asphalt to Metal. Taking all Aspects into Consideration Thermal Movement and Load Deflections 3D Design from Prokol Were Created Supporting The New Application.

Completed Walkways

Completed Handrail Detail & Communal Walkway Hydrophobic Waterproofing Complete, Life Expectancy of This Application at 3 mm In Excess of 50 Years Minimum.

The Prokol Hydrophobic 136T 8 Second Cure Pure Polyurea Coating Has 330% Elongation, So Substrate Expansion Joints are Renewed Where Required & Then Sealed Into the Seamless Waterproofing Floor Coating - Most Other Systems Cannot Achieve This Level of Performance, They Finish at The Expansion Joint & Then Start Again On The Opposite Side Leaving Water To Ingress The Joints.

Neat Finishing Detail Creating Full Tanking Waterproof Finish

The walkway coating Prokol 136T is totally impenetrable and has high adhesion, 4 - 6 mpa (mega pascal) on concrete, highways standards is 1.2 mpa so over four times the standard. This high bond adhesion is also per mm so tracking water can run between the coating and substrate. As the membrane is also breathable any trapped moisture can release as well as it dissipating with gravity. 136T will also strengthen concrete by 50% and brickwork by 75% via containment.

Environmental Health & Other Key Benefits of the 136T Pure Polyurea Floor Coating - Cleaning & Maintaining

The 136T coating is fully hydrophobic and chemically resistant to acids from food, animal or human soiling. These stains will just dry on the surface leaving no odour. These chemical resistant properties play a key part in the products' attributes in hard wearing areas. If required the coating can be steam cleaned up to 180 degrees, but usually just soap and water will suffice. If necessary a further Prokol sealer can be applied over the waterproofing coating to aid in clean-ability where heavy abuse or heavy soiling is present. Prokol also offer small cordless scrubber cleaning equipment that comprises of two tanks, one clean water tank and the other to remove dirty water from the surface. Usually mopping surfaces see dirty water moved around and in non air drying temperatures autumn & winter mopping leave wet substrates, causing problems. Our automated system is aqua vacuum based and removes nearly all the excess dirty water from the coating. The Prokol structural waterproofing system is breathable & fully hydrophobic application. It is designed to halt the degradation and high cost of structural repair and redecoration. The existing open concrete or asphalt ssee's applications of strong cleaning chemicals to maintain cleanleness and environmetal health, but these high dosage's of cleaning materials will accelerate the structural degradation leading to more maintenance and more repair costs repetitively. Our automated cleaning system is supported by full certified training by the manufacturer to the estate cleaning services as part of a Prokol turn key solution.

Other Important Key Benefits of The 8 Second Cure Polymer - Stair Wells & Fire Escape Points Can Be Kept In Constant Use In Case of Emergency. Prokol Pure Polymers has Zero VOC's No Odour Water Approval BS6920

Old granolithic staircase with no structural waterproofing will be subject to future high cost structural repair, protection is paramount to keeping asset costs down. Here the approved Prokol applicators have already diamond ground the substrate and coated the leading edge under the handrail ready for the main 8 second cure coating to seal the concrete stairs.

Warm Roof Upgrades

Pre Condition Roof Surveys Were Carried Out to All Estate Blocks

Following a full assessment & pre - condition report of all the roof areas on this estate, it was found only three out of eight required a full strip back to the original substrate due to high moisture levels. Water ingress and damage was severe internally to all top level living spaces on the wet roofs, the other roof areas were able to be cost effectively warm roof overlaid. From the core sample results the thermal upgrades levels where calculated in conjunction with full condensation risk analysis.

All buildings move constantly and so should its construction products, this movement measured by elongation or e-moduluselongation required to allow for expansion and contraction with heat and freeze thaw environmental cycles. The higher the elongation in the building product the longer chance it will protect the asset for the life of the building, giving a zero maintenance & whole of life application result. well into the future needs to be aspecified correctly and understood especially at transition around lateral to vertical joint transition. The constantly changing environmental demands placed on products needs careful evaluation by the specifier, Prokol technical advisors proficient in both building & construction engineering match Prokol products to the application with precision. Prokol technical advisors insist on explaining & educating the asset owner or specifier on key points to insure they understand how important the application plays a part in future their building. Thermal expansion & contraction along with thermal shock being paramount in these explanations.

When installing a new warm roof application or overlay system moisture vapours or out gassing especially from isulation with will still be trapped in the roof area, not allowing for free relaese can place thses gases back into the building which is not healthy for the occupants. Prokol Polymers specify a primary waterproofing self vented carrier membrane, this carrier membrane is high bond self adhered and does not require any hot works application. The diamond pattern of the Prokol carrier sheet shown in the image below exhibits channels that allow any trapped moisture to transfer across the entire roof area and breathe out through the membrane upstand. This specified vented carrier membrane also acts as a primary roof waterproofing system, along with the seamless Prokol membrane it is like having two systems two lines of defence, double the protection. Also as the membrane is not directly fully bitumen bonded to the insulation and not result like standard felt systems pop up in blister in one area placing stress on

Unlike a lot of traditional water resistant applications like felts and polyurethane liquids, warranties are usually void if the roof drains are not cleared causing sitting water, or foliage & plant growth is not removed.

With the Prokol Hydrophobic membrane its designed to sit underwater for life without degrading, plant growth cannot penetrate the chemically resistant membrane due to its high non penetrative tensile strength, these everyday issues will not effect the Prokol manufacturer warranties as its designed with zero maintenance in mind.

The Prokol System Offers Two Lines Of Waterproofing Defence Not Just One, Firstly The Self Adhesive Felt Sacrificial Waterproofing Layer & Then The High Performance 3 mm Fully Hydrophobic Pure Polyurea Membrane.
