CLIENT LIST

Dryseal_Brochure_March2018

What is Dryseal?Pre-cured System Dryseal is a fully mechanically fixed waterproofing membrane system made from Glass Reinforced Polyester, which is commonly referred to as GRP or fibreglass. It is different from ‘wet lay’ systems in that the whole system is made up from

preformed components packed ready to fix and joint on site.

Quality Dryseal is manufactured in the UK in accordance with strict BS EN ISO 9001-2015 Quality Control procedures. British Board of Agrément

(BBA) product performance and compliance standards are applied to Dryseal.

Speed of Installation The means of fixing and jointing make Dryseal quicker to install than ‘wet lay’ systems but more robust than ‘single ply’ PVC membranes,

because of the high impact resistance.

Dependable Dryseal is a versatile, flexible system which can be used with ease on projects in ‘cold’ or ‘warm’ roof configurations from a Leisure Centre through to a domestic extension. Easy

to detail, repairable and able to be refurbished in situ, It is proven to deliver 20 year guaranteed BBA certified dependability, with an expected life in excess of 30 years.

The Dryseal membrane sheets are set out, then overlapped and fixed to the substrate.

The preformed trims and other components are then installed to accommodate drainage, roof lighting, ventilation, parapet and other details. Next, the components are laminated together using the same compounds as those used in manufacturing.

Dryseal can be installed without pitch restriction - from 0 degrees to vertical.

At this stage the roof is waterproof.

The finish is provided by the application of a pigmented polyester top coat which encapsulates the entire roof surface. This surface finish can be matched to any BS and RAL colour as described on page 11.

For more detailed step by step installation guides, please contact us.

Commercial

Major clients Dryseal can be used for a wide range of commercial installations, such as this private hospital in Sligo, Ireland, where the original failed asphalt roof was overlaid with 100mm insulation and Dryseal. The improvements have resulted in huge savings to heating costs.

Nationwide use Dryseal’s ease of detailing, robust resistance to damage, extensive colour choice and aesthetics have led to repeated use by major clients across the UK and Ireland.

From a hotel in Poole to a school in the Scottish Highlands, from a leisure centre in Nottinghamshire to a hospital in Ireland, Dryseal has been successfully installed for over 25 years and continues to be the first choice for many specifiers.

Housing

Insulated roof Be it a new extension, a ‘green’ roof or the upgrade of an existing building to a ‘warm’ roof to comply with current Building Regulations, Dryseal can provide the solution for your domestic project.

Refurbishment Dryseal can be easily used in a re-roof. The existing roof deck can be used, as long as it is in good condition, and with the addition of insulation to form a ‘warm’ roof, the cost benefits become rapidly obvious.

• Reduces land-fill costs if the existing roof covering is overlaid.

• Reduces labour costs.

• Reduces risk during installation due to shorter ‘open’ times.

• Reduces long-term risk as Dryseal is guaranteed against leaks for 20 years.

• Lower embodied CO2 than any comparable roofing system.“ ”

Heritage

Lead replacement, life & theft deterrent Dryseal can be fitted with decorative ‘rib’ trims which help give the appearance of a roll on a lead roof. The system has been widely used on Grade 1, 2 and 2* listed buildings, as approved by English Heritage, National Trust and Historic Scotland.

Costed over a 50 year lifespan, Dryseal can be refurbished ‘in situ’, extending the installed life of the system way beyond that of other roof coverings, at considerably lower costs. The system holds highly regarded ‘Secured by Design’ accreditation, approved and recommended by UK Police as a theft deterrent. The total lack of scrap value in Dryseal eliminates any worth to the metal thief.

Environmentally friendly & low risk An additional benefit to Listed Buildings is the ability for Dryseal to be completely removed from the building without damage, allowing the original covering (lead, copper etc.) to be re-fitted, if required. This ‘reversibility’ due to being mechanically fixed gives Dryseal advantages that many other modern systems do not possess. At the end of its service life, Dryseal can be removed and taken away for recycling back into new products, helping contribute to Dryseal’s exceptionally low embodied carbon footprint.

Dryseal is designed to minimise risk during and after installation, as it is installed without the use of naked flames or intensive heat sources, potentially critical considerations on older buildings.

Dryseal looks like lead, it’s got longevity and it will save this church for generations to come.

Green roof and terrace/balcony areas

Green roof The Dryseal system has many uses as a waterproofing membrane under a green roof as shown in this ‘Passive House’ in Melrose, Scotland. A very high resistant to impact damage makes the system one of the most reliable on the market for this kind of installation.

Terrace or balcony waterproofing Dryseal is highly suitable for use as a waterproofing layer under timber decking or under concrete paving and many walkway systems.

Low risk Dryseal achieves unrestricted use under Fire Regulations, even when installed directly over a combustible substrate, without the need for a surface protective fleece. This feature delivers fire performance without the risk of silt

The system also hold ‘Zero falls’ certification under certificate 95/3114 - ensuring peace of mind for specifiers of green roof and terrace applications.

Dryseal is suitable for occasional limited foot traffic. Where there is a need for regular roof access then Dryseal can be adapted to meet the desired requirements.

Thermal expansion, size and colour

Flexible Dryseal is mechanically fixed and accommodates thermal expansion and contraction forces within the system itself, unlike ‘wet lay’ GRP systems. As a result of this, there is no need for expansion joints within the membrane, except where a construction joint or localised building movement is present, and there is no restriction to a roof’s size.

Colour choice The colour of Dryseal’s polyester top coat can be tailored to suit client requirements and mixed to any BS or RAL colour.

Quantity and cost details are available upon request.

The roof below was finished in blue at the request of the college to match their own colour scheme.

Approved Contractors and 20 year guarantee

Fully trained installers Dryseal can only be fitted by fully trained Approved Contractors after completing our two day training course. The course covers the basic principles behind GRP as a material, as well as the pitfalls which can be encountered when installing a flat roof. Our Approved Contractors cover the UK and Ireland.

High standards As we promote high standards of workmanship we encourage our Approved Contractors to affiliate themselves to the National Federation of Roofing Contractors (NFRC) and achieve CompetentRoofer status.

NFRC The NFRC actively promotes high quality standards and pride in the job, representing 70% of the UK roofing industry. Hambleside Danelaw are pleased to be a long-standing NFRC Supplier Member and prominent supporter of CompetentRoofer.

Site Support Once an Approved Contractor has trained, we offer on-going site technical support and assistance, to ensure that high standards are maintained.

Insured guarantee Upon satisfactory completion, a 20 year ‘leak free’ guarantee is issued, along with details of the pre-paid insurance cover against a claim should the installing contractor have ceased to trade.

Dryseal provides a meaningful, enforceable insurance-backed guarantee that provides peace of mind for all.
